Ryanair, Vueling, and Iberia Within Spain: Total Cost With Bags

You spot a domestic flight from Madrid to Seville for less than the price of a sit-down lunch, book it in a rush of excitement, and then watch the total climb at every screen: a fee for your cabin trolley, a fee for the suitcase, a fee to choose a seat next to your partner. By the time you reach the payment page, the bargain has tripled. This guide breaks down how Ryanair, Vueling and Iberia actually charge for bags on flights within Spain, how to calculate a true door-to-door cost, and when the train or bus quietly beats all three.

I have flown all three airlines between Spanish cities more times than I can count, usually with more luggage than I meant to bring. The lesson I learned the expensive way is that the headline fare tells you almost nothing. What matters is the total for your real trip, with your real bags, from your front door to your destination.

Why the Headline Fare Is Never the Real Price

Domestic flights in Spain are sold on a model that splits the journey into small pieces and charges for each one separately. Understanding this model is the first step towards never being surprised at the gate again.

Unbundled Fares Explained

An unbundled fare means the base ticket covers only the seat itself, and sometimes not even a choice of seat. Everything else is an extra: a full-size cabin bag, a checked suitcase, seat selection, priority boarding, and sometimes even printing a boarding pass at the airport.

Low-cost airlines pioneered this approach, but full-service carriers have adopted versions of it too. The logic is that travellers with only a small backpack should not subsidise those with two suitcases. The problem is that most people, especially expats moving between cities or families on holiday, are in the second group.

Before comparing any prices, decide honestly what you are going to carry. A weekend in Valencia with a backpack is a completely different calculation from a two-week trip to Galicia with a suitcase for each family member.

The Three Bag Categories That Matter

Almost every airline flying within Spain now uses three categories of luggage:

1. Small personal item: a handbag, laptop bag or small backpack that fits under the seat in front of you. This is usually included in the cheapest fare.
2. Cabin trolley: the classic wheeled carry-on that goes in the overhead locker, usually up to around 10 kilograms. On low-cost fares, this is often an add-on.
3. Checked bag: a suitcase that goes in the hold, typically sold in weight bands such as 10, 20 or 23 to 25 kilograms depending on the airline.

The exact sizes differ between airlines by a few centimetres, and those few centimetres are where gate fees come from. Measure your bags at home, including wheels and handles, and compare them with the dimensions listed on the airline’s own baggage page before you book.

Why Bag Fees Change From Flight to Flight

Bag fees on low-cost airlines are not fixed. They tend to vary by route, by date, and by how close to departure you add them. Adding a bag during the initial booking is generally cheaper than adding it later in the “manage booking” section, and adding it at the airport is usually the most expensive option of all.

This is why I never quote a single price for “a Ryanair bag” or “a Vueling bag”. The figure you saw on a friend’s booking last month may bear no relation to what you will be offered on your own flight. Always price the bags at the moment you book, on the actual flight you want.

Spain’s consumer affairs ministry has also taken action against several low-cost airlines over charging for cabin bags, and the airlines have challenged those decisions. Until the matter is settled for good, assume you will be asked to pay for a trolley on the cheapest fares, and check the airline’s own conditions when you book.

Which Airlines Fly Within Spain

Ryanair, Vueling and Iberia carry a large share of domestic passengers, but they are not the only options. Air Europa, Volotea and Binter also fly domestic routes, and Binter is particularly important for the Canary Islands. Iberia’s domestic network includes flights operated by Iberia Express and by Air Nostrum under the Iberia Regional name.

For a wider picture of when flying makes sense at all, Domestic Flights in Spain: When They Beat the Train is a useful starting point.

Ryanair, Vueling and Iberia: How Each One Structures Bags

Each of the three airlines takes a slightly different approach. None of them is always the cheapest. The cheapest option depends entirely on how much luggage you carry and which route you fly.

Ryanair: The Most Aggressively Unbundled

Ryanair’s cheapest fare typically includes only a small personal item that must fit under the seat. If you want a cabin trolley, you usually need to buy a priority boarding product that includes it, or a bundled fare that includes it. Checked bags are sold separately, generally in a lighter and a heavier weight band.

Points to watch with Ryanair:

• Check in online. Checking in at the airport can carry a substantial fee. Do it in the app or on the website within the online check-in window, and keep your boarding pass on your phone.
• Seat selection. If you do not pay for a seat, the airline assigns one, which may separate a group travelling together.
• Bundles. Ryanair sells bundles that combine a trolley, seat and priority boarding. They can be good value if you would have bought those items anyway.
• Gate checks. If your personal item is too large at the gate, the fee charged there is typically much higher than buying a bag in advance.

Ryanair is often unbeatable for travellers with only a backpack. For travellers with a checked bag each, the advantage can disappear quickly.

Vueling: Fare Families Built Around Bags

Vueling, which belongs to the same airline group as Iberia, structures its fares as families. The basic fare usually includes a small under-seat bag. Higher fares add a cabin trolley, seat selection and, depending on the fare and route, a checked bag and more flexibility to change.

Points to watch with Vueling:

• Compare fare families, not add-ons. Sometimes a higher fare that includes a trolley and seat costs less than the basic fare plus the same extras bought individually.
• Check-in bag weights. Vueling’s checked bag allowances are typically generous in weight compared with some low-cost carriers, but check the details for your fare.
• Barcelona hub. Vueling’s biggest base is Barcelona, so it often has the most frequencies from there, which can mean more choice of times and fares.
• Avios. Vueling’s loyalty programme uses Avios, so you can earn and spend points within the same group as Iberia.

Iberia: Full Service, Mostly

Iberia’s short-haul fares are also split into families, from a basic fare upwards. Historically, Iberia’s domestic fares have been more generous with cabin luggage than the pure low-cost carriers, and checked bags are included on the higher fare families. Check exactly what your chosen fare includes, because the cheapest fare is not the same as the classic full-service ticket.

Points to watch with Iberia:

• Regional aircraft. On flights operated by smaller regional aircraft, overhead lockers are smaller, and trolleys are sometimes taken at the aircraft door and returned on arrival.
• Connections. If your domestic flight connects to an international flight on the same ticket, the baggage allowance of the long-haul ticket often applies to the whole journey, which can make Iberia the clear winner.
• Madrid hub. Iberia’s base is Madrid-Barajas, with frequent domestic connections from there.

Because prices change constantly, this table compares the structure of each airline, not the amounts. Run the numbers for your own trip, as shown below.

Calculating Your True Door-to-Door Cost

The only fair comparison is the total from your door to your destination, with your actual luggage. Here is how I do it before every domestic trip.

Step-by-Step Cost Calculation

1. Define your luggage. Write down exactly how many under-seat items, trolleys and checked bags your group is carrying.
2. Price each airline with those bags. Go through each airline’s booking flow up to the payment page, adding the bags and seats you need. Note the total.
3. Check fare families. For Vueling and Iberia, compare the basic fare plus extras against the next fare up.
4. Add the airport transfer at each end. Include the metro, bus, train or taxi from your home to the departure airport and from the arrival airport to your accommodation.
5. Add the time cost. Airports require arriving well ahead of departure. Add that time and compare it with the total time by train or bus.
6. Compare with ground transport. Search the same journey by train and bus for the same day.

Step six is where Omio saves a lot of effort. Omio lets you search trains, buses and flights for the same route and date on one screen, so you can see immediately whether the AVE, an intercity coach or a flight fits your trip best. It does not replace step two, because you still need to work out the baggage cost for the flights, but it shows you instantly whether a ground option exists that would make the whole baggage question disappear.

A Worked Example With Round Numbers

Imagine a couple travelling from central Madrid to central Barcelona with one trolley and one checked bag between them. The figures below are round numbers to illustrate the method, not real quotes from any airline.

Cost item	Low-cost flight	Train
Two base fares	70 euros	120 euros
Trolley	30 euros	Included
Checked bag	35 euros	Included
Seats together	20 euros	Included
Transfers to and from both airports or stations	30 euros	10 euros
Total	185 euros	130 euros
Door-to-door time	About 4 hours	About 3.5 hours

In this example, the flight looked cheaper at the first screen, at 70 euros against 120. Once bags, seats and airport transfers are added, the train is 55 euros cheaper and slightly faster door to door. Your own numbers will differ, but the pattern is extremely common on routes served by high-speed trains.

If you want to dig deeper into this particular route, Madrid to Barcelona: Train vs Flight vs Bus Compared goes through it in detail, and Renfe vs Ouigo vs Iryo vs Avlo: Spain’s High-Speed Competition Compared explains the differences between the train operators.

Do Not Forget Airport Transfers

Airport transfers are the hidden cost that people forget most often. Madrid-Barajas and Barcelona-El Prat both have good public transport, but a taxi at either end of a trip adds a noticeable amount, and smaller airports may have limited buses late at night. Plan the transfer before you book an early-morning or late-night flight. For Madrid specifically, see How to Get From Madrid Airport to the City Center.

If you are connecting between a flight and a train, give yourself a generous buffer, as explained in Connecting Between Spanish Airports and Train Stations: Timing Your Transfer.

When Each Option Usually Wins

Your situation	Usually cheapest	Why
Solo traveller with only a backpack	Low-cost flight or Avlo-style budget train	The base fare is all you pay
Couple with a trolley each	Compare carefully	Bundles and fare families vary by route
Family with checked bags	Train, or a full-service fare	Bags and seats add up fast on low-cost fares
Route with no high-speed train	Flight	Ground travel may take a whole day
Island travel	Flight or ferry	No train option

Routes Where the Choice Is Different

Not all domestic routes are like Madrid to Barcelona. On some, flying is the only realistic option. On others, the train wins on almost every count.

Mainland Routes With High-Speed Rail

On routes like Madrid to Seville, Málaga, Valencia, Zaragoza or Barcelona, the high-speed train is a strong competitor. Stations are central, there are no strict liquid rules, and you can bring generous luggage without extra charges. Search these routes on Omio first, because the train may well make the flight comparison unnecessary.

Routes Where Flying Makes Sense

Flying tends to win on long diagonal routes across Spain where there is no fast direct train, such as Barcelona to Seville, Bilbao to Málaga or Valencia to Santiago de Compostela, and on routes to the islands. Even on these, it is worth checking Omio for overnight buses or train combinations, especially if you are carrying a lot of luggage.

Flights to and Between the Islands

For the Balearic and Canary Islands, the choice is between flying and taking a ferry. Ferries let you bring much more luggage and even a car, but they are slower. The trade-offs are covered in Balearic Islands: Ferry vs Flight Priced Out for Each Island and Cheapest Flights to the Canary Islands: Airlines, Booking Windows, and Baggage.

Residents of the Canary Islands, the Balearic Islands, Ceuta and Melilla are entitled to a large state-funded discount on flights between their island or city and the rest of Spain, and between islands. If you are a registered resident there, make sure your residency is recorded correctly when you book, because the discount is checked at the airport. Within the Canaries, regional airlines and ferries compete closely, as explained in Inter-Island Travel in the Canaries: Ferries and Regional Flights.

Large Families and Other Discounts

Spain also offers discounts on domestic travel to officially recognised large families, known as familia numerosa, on many transport modes. If you hold the card, check whether the discount applies to your chosen flight or train before booking, and carry the card when you travel.

The Other Extras That Inflate Your Total

Bags are the biggest add-on, but they are not the only one. A handful of other charges can push the total of a domestic flight well past the train fare, and they are easy to overlook when you are focused on suitcase sizes.

Sports Equipment, Instruments and Bulky Items

Golf clubs, bicycles, surfboards, skis and musical instruments are treated as special luggage on all three airlines. They usually need to be booked in advance, carry their own fee, and may be limited in number per flight because hold space is finite. A guitar in a soft case is not a cabin trolley, whatever you tell yourself at the gate.

If you are heading to the Sierra Nevada with skis or to the Canaries with a board, price the sports equipment as part of the initial comparison. On mainland routes, a train or a coach with a generous luggage policy may be dramatically cheaper. For bicycles, check the rail operator’s own rules, because high-speed trains usually require bikes to be dismantled and bagged.

Infants, Children and Pets

Travelling with a baby on a domestic flight usually means paying an infant fee even though the child sits on your lap, and adding allowances for a pushchair and car seat, which airlines generally carry at no extra charge but with conditions. Older children pay a seat fare like adults on most domestic routes, and on low-cost fares the airline may require at least one adult to sit with them, which can mean paying for seat selection.

Small pets in the cabin are accepted by some airlines on domestic routes and not by others, always with a fee and a weight limit for pet and carrier combined. Spanish trains also accept small pets on many services, with their own conditions. If the dog is coming, compare the pet policies before you compare the fares, because they rule options in or out completely.

Payment, Changes and Name Corrections

Two smaller traps catch people regularly. First, changing the date or time of a cheap fare can cost more than the original ticket, because you pay a change fee plus any fare difference. If your plans are uncertain, a more flexible fare family may be the better choice from the start, and trains often have more forgiving change rules.

Second, name corrections. A spelling mistake in a passenger name can carry a fee to correct, and Spanish double surnames are a classic source of errors. Enter names exactly as they appear on the ID document each passenger will show at the airport.

Finally, look at how you pay. Paying in a currency other than euros can trigger a conversion at a poor rate, so if the booking page offers to charge you in your home currency, decline and pay in euros with a card that has low foreign transaction costs. It is a small saving per ticket, but across a family and a return trip it adds up to a meaningful amount.

Three Real-World Scenarios Worked Through

Theory only goes so far. Here are three trips of the kind I and friends have actually made, worked through with the method above. As before, the figures are round illustrative numbers designed to show how the totals behave, not quotes from any airline or rail operator.

Scenario One: The Solo Weekend in Seville

Lucía lives in Barcelona and wants a long weekend in Seville in late October. She travels light: one small backpack that fits under a seat, nothing else. There is no fast direct train that gets her there in a comfortable time, so this is a route where flying makes sense.

Because she carries only an under-seat bag, the cheapest fare on any of the three airlines covers everything she needs. She does not care where she sits, so she skips seat selection. Her total is essentially the base fare plus her airport transfers. In this situation, whichever airline has the lowest base fare on her chosen days wins, and the low-cost carriers frequently come out ahead.

The only real risk for Lucía is her backpack. If it is slightly too big, she could face a gate fee that is larger than her fare. She measures it at home, removes the bulky jacket, and wears it on the plane instead. That one habit is worth more than any fare alert.

Scenario Two: The Couple Moving Flats From Valencia to Madrid

Tom and Ana are moving from Valencia to Madrid for a new job. Their furniture is going by van, but they want to bring two large suitcases and two trolleys with them on the day. On paper, a low-cost flight with a tempting base fare looks like the cheapest option.

Once they price their real luggage, the picture changes completely:

Cost item	Low-cost flight	High-speed train
Two base fares	60 euros	100 euros
Two trolleys	50 euros	Included
Two heavy checked bags	80 euros	Included
Seats together	20 euros	Included
Taxi to and from airports or stations	70 euros	40 euros
Total	280 euros	140 euros

The train costs half as much in this example and drops them in central Madrid, where a short taxi ride takes them to their new flat. Searching the route on Omio first would have shown them the train option within seconds, before they spent an evening comparing baggage fees. Trains on this route still have luggage limits, but they are generous and rarely enforced the way airline weight limits are.

Scenario Three: The Family Trip From Bilbao to Tenerife

The Garcías, two adults and two children, are heading from Bilbao to Tenerife for a week in the summer holidays. There is no ground alternative worth considering, so the question is purely which flight and which fare.

With four people, every add-on is multiplied by four. Two checked suitcases shared between the family, two trolleys for the adults, small backpacks for the children and seats together for a family with young children add up quickly. In this case, a fare family that bundles a checked bag and seats for each passenger may cost less than the basic fare with extras added one by one. The family prices both versions on each airline before deciding.

They also check whether a connection through Madrid on a single ticket would let them check their bags through to Tenerife, which can be easier with children than a direct low-cost flight from a smaller airport with fewer departures. Sometimes the convenience is worth a little more; sometimes the direct flight wins outright. The point is to compare like with like, with the luggage they are really carrying.

Booking Smart: Practical Tips to Keep Costs Down

Once you know the structure of the fares, a few habits will save you money and stress on every trip.

Before You Book

1. Start with a multimodal search. Search the route on Omio to see trains, buses and flights side by side, then decide whether flying is worth pricing in detail.
2. Pack before you book. Decide what you are carrying first. Booking the wrong fare and adding bags later almost always costs more.
3. Compare fare families. A higher fare that includes a trolley and seat can be cheaper than the basic fare plus extras.
4. Avoid peak days. Friday evenings, Sunday evenings and the start and end of public holidays are generally the most expensive times to travel.
5. Check the arrival airport. Some airports are much further from the city centre than others, which changes the transfer cost.

At the Airport

1. Check in online. Never pay an airport check-in fee you could have avoided.
2. Measure and weigh your bags. A luggage scale costs less than one overweight fee.
3. Board early if you have a trolley. On full flights, overhead space runs out, and late boarders may have their trolleys taken to the hold.
4. Keep valuables and medication with you. If your trolley is gate-checked, take out anything you cannot afford to lose.

Protecting Your Trip

Delays and cancellations happen on domestic routes, especially during summer and around strikes. Under EU rules, passengers on flights within the EU may be entitled to compensation and care for long delays and cancellations, depending on the circumstances. Keep your boarding passes and receipts. For broader cover, including missed connections and lost luggage, see Travel Insurance for Trips to and Within Spain.

My Honest Conclusion

None of the three airlines is always the cheapest. Ryanair is often unbeatable for a light traveller with a backpack. Vueling is strong out of Barcelona, especially when you compare fare families. Iberia makes sense for connections and for travellers who value a more traditional service. And on many routes, the train beats all three once your suitcase is part of the equation.

The smartest habit I have built is to start every domestic trip with a search on Omio, compare the ground options with the flights, and only then dig into each airline’s baggage pricing for the flights that are still in the running. It turns a frustrating hour of tabs and calculations into a ten-minute decision, and it means the price I see at the start is much closer to the price I actually pay.
