Mistakes
7 Ryanair bag mistakes (and how to avoid them)
Updated Sep 17, 2026 · 7 min read
The most expensive Ryanair bag mistake is a bag that reaches the boarding gate unpaid or oversize: €46 to €75 to put a checked bag in the hold there, and €70 to €75 for an oversize cabin bag, per bag and per one-way flight. The other six cost less individually and are easier to make, because they all come from Ryanair's products being four different shapes rather than a ladder.
1. Looking for a cabin bag to buy on its own
- Cost
- €12.49 to €36 per person per one-way flight for Priority and 2 Cabin Bags, the only product that carries the 10 kg cabin trolley.
- Why it happens
- There is no standalone cabin bag line in the Ryanair booking flow, so people scroll past the extras screen looking for one and conclude the bag is not available. The 55 x 40 x 20 cm, 10 kg overhead bag exists only inside Priority and 2 Cabin Bags, which also covers priority boarding and the free personal item.
- What to do
- Look for the priority line rather than a bag line. If you want the overhead bag, that is the product, and it is the only one that carries it. If you only want the free under-seat bag, you need nothing at all: it is included on the cheapest Basic fare and on every bundle above it.
2. Buying Plus for a trolley, or Regular for a suitcase
- Cost
- A 20 kg checked bag bought separately afterwards is €21.49 to €59.99 at booking and €39.99 to €75 later, per person per one-way flight.
- Why it happens
- The bundles are four different shapes, not four rungs of one ladder. Regular carries the priority cabin bag and no checked bag. Plus carries a 20 kg checked bag and no trolley and no priority. Flexi Plus carries two cabin bags and no checked bag. The names suggest each level contains the one below, and none of them does.
- What to do
- Read the contents list on the bundle screen before the price. Decide which bag you need first, then pick the product that carries that specific bag. If you need both a trolley and a suitcase, no single Ryanair bundle carries both, so one of them has to be bought separately.
3. Taking the recommended bundle without pricing the parts
- Cost
- In two tests for a family of four in February 2026, a Basic fare plus the identical extras came out GBP 59 and GBP 35 cheaper than the bundle.
- Why it happens
- The bundle is presented as the sensible default and looks like a saving. Which? ran that comparison around thirty times over two years and found the bundle cheaper than Basic plus the same extras exactly once. Bundles apply the same extras to every passenger, so they get worse with group size: four people rarely need four trolleys and four seat reservations.
- What to do
- Price both versions in the same session before paying. Add up the Basic fare plus only the extras you would have bought, then compare that with the bundle total for the whole booking. Ryanair says its extras are dynamically priced so a bundle cannot be worse than its parts, and has published no test of its own.
4. Costing a return trip as one bag fee
- Cost
- Every Ryanair bag fee is per passenger per one-way flight. Two people with one 20 kg bag each on a return is four chargeable bag events, not one.
- Why it happens
- The booking flow shows the outbound extras first and the number that sticks in your head is the one you saw first. Ryanair's fee table annotates the checked bag rows as minimum and maximum charges per item per flight, and the Bulgarian table marks them per flight in Bulgarian, but the price you were quoted still reads as a trip total.
- What to do
- Multiply by the number of passengers and then by two before you decide whether a fare is cheap. A €36 fare to Rome with a bag at say €25 each way is an €86 trip for one person. That arithmetic is what decides whether a deal is worth taking, which is why every deal page here prints the bag rules beside the fare.
5. Carrying a 10 kg check-in bag through to the gate
- Cost
- €46 to €75 per bag per one-way flight to place it in the hold at the gate, against the €10.49 to €44.99 the bag itself cost at booking.
- Why it happens
- The 10 kg bag Ryanair sells is a checked bag, not a cabin bag, and it has to be dropped at the bag desk before security. It is the same size as the cabin trolley, which is what makes the mistake so easy: the bag fits the overhead locker perfectly well, and the boarding pass says it belongs in the hold.
- What to do
- Check what you bought before you leave for the airport. If the booking says 10 kg check-in bag, go to the bag desk and allow queue time for it. If the booking says Priority and 2 Cabin Bags, the same bag stays with you. Two different products, the same dimensions, opposite instructions.
6. Adding a 10 kg bag online after booking without checking the desk
- Cost
- Ryanair quotes a flat €35.99 at the airport bag-drop desk for the 10 kg bag, while the post-booking online band for the same bag runs €24 to €75.
- Why it happens
- Buy online is sound advice that has one published exception, and this is it. Ryanair's fee table carries a fixed airport bag-drop price for the 10 kg tier, so once the booking has closed the online price can climb past the desk price on a busy route. Almost every guide repeats the general rule and omits the exception.
- What to do
- Compare the two numbers when you are already past the booking. If the post-booking online quote for the 10 kg bag is above €35.99, the bag-drop desk is cheaper, provided you are at the airport early enough to use it. This applies to the bag desk only, never the gate, and only to the 10 kg tier.
7. Buying a bag just in case
- Cost
- No refund at all. Ryanair states that a cabin or check-in bag cannot be removed from a booking or refunded once it has been bought.
- Why it happens
- Adding a bag feels reversible because most of the booking is: seats can be changed and flights can be moved for a fee. Baggage is the one line that cannot be undone, so a bag bought to keep options open is money spent whether or not the bag travels. People also buy one in the belief they can downgrade later if they pack light.
- What to do
- Pack first, decide second, where the dates allow it. If the trip is far enough out, put the bag on once the packing is real rather than at the moment of booking. If the fare is a deal that will not wait, buy the bag you are confident you need and treat the rest as settled.
Questions
Is Flexi Plus a good way to get bags?
No. On the flight Which? tested in February 2026, the same extras bought separately came to GBP 186, which was GBP 168 below the Flexi Plus price. Flexi Plus carries two cabin bags and no checked bag, and its real value is the waived flight change fee, not the baggage.
Can two people share one checked bag allowance?
Bags can be pooled between passengers on the same booking who have checked bags, so two 20 kg allowances can be packed as 15 kg and 25 kg. No single piece may go over 32 kg. It is a genuine saving and most travellers never hear about it.
What does checking in at the airport cost?
€55 per passenger per sector, and €30 from Spain or €40 from Austria. Free airport check-in inside the Plus and Flexi Plus bundles applies only to bookings made before Aug 14, 2025, so anyone booking now pays it.
Does Ryanair Prime help with bags?
No. Prime closed to new members in November 2025, about eight months after it launched, and existing members keep benefits until October 2026. It covered seat reservations, insurance and member fare sales, and never included baggage at all.
Ryanair is not difficult to fly cheaply, but it does sell four products that sound like one. Decide which bag you need, buy that, and the fare is the whole cost. Live Ryanair routes are on the deals from Plovdiv and Sofia pages.
