How to avoid the gate fee for an oversize bag

Every other place you can buy baggage is cheaper than the boarding gate, and the gap is not small.

Ryanair charges €70 to €75 to put an oversize cabin bag in the hold at the gate. Wizz Air charges €55 to €65 for a cabin bag at the airport or gate. flydubai charges AED 200, which it quotes as $55 and which is around €50, for hand baggage caught oversized or overweight at the gate, on top of anything already charged at the check-in desk.

All of those are per bag and per one-way flight. None of them buys you anything you would have wanted.

Set them against the fares on this site. On a cheap European return, one gate charge in each direction can cost more than the ticket did. That is the whole argument for spending five minutes with a tape measure.

Ryanair publishes two separate penalties in the more-information column of its fee table, and most third-party guides average them into one wrong number.

The first applies to a passenger arriving at the gate with a cabin bag that will not go into the sizer. That bag is refused, or placed in the hold, for €70 to €75.

The second applies to a passenger who bought a 10 kg check-in bag and carried it to the gate instead of dropping it at the bag desk before security. That is €46 to €75.

They are different mistakes. One is a bag that is too big. The other is a bag in the wrong part of the airport.

In both cases Ryanair states that you leave the bag at the aircraft steps or in the gate bag trolley, so you are paying a fee and travelling without the bag either way.

This is the detail that makes the Wizz Air charge feel unfair, and it is in the contract rather than in staff discretion.

Wizz Air's general conditions of carriage state that carriage of oversize or overweight cabin baggage is subject to payment of the excess fee at the boarding gate, and that the airline reserves the right to carry that baggage as checked baggage. So the €55 to €65 does not buy your bag a seat in the locker. It buys the bag a place in the hold.

A second clause goes further. Wizz Air may carry even a fully compliant trolley in the hold, free of charge, for operational or safety reasons. WIZZ Priority guarantees that you may bring the bag, not that it stays with you.

Personal property is exempt from that: your coat, your phone and your reading material stay with you whatever happens to the bag.

The measurement that decides this is taken at the gate, with the bag full, and that is the measurement to reproduce at home.

Wizz Air's conditions of carriage state that the published dimensions include side pockets. Handles are excluded and wheels may add no more than 5 cm. So a soft bag that sits at exactly the limit when empty can be over it once the side pockets are loaded and the front panel bulges.

Ryanair's sizer is a rigid frame and the bag is expected to drop into it unaided. Nobody is going to press it in for you.

The home test takes a minute. Pack the bag as you will carry it, then measure the widest point of each face, including any pocket that is now sticking out. If a face is over, move that item into the middle of the bag rather than trusting the give in the fabric.

A soft bag forgives this. A hard shell does not.

Three different frames are in play on these routes, and a bag bought for one airline can fail at another.

The free under-seat bag is 40 x 30 x 20 cm on both Ryanair and Wizz Air, so that one is consistent. The overhead trolley is not: Ryanair's is 55 x 40 x 20 cm and Wizz Air's is 55 x 40 x 23 cm.

That 3 cm matters. A case bought to the Wizz Air trolley size is three centimetres too deep for Ryanair's frame, and it is exactly the kind of bag that has passed a dozen times before failing once.

flydubai is different again, at 55 x 38 x 20 cm, and unlike the European low-cost carriers it caps hand baggage at 7 kg, which it does weigh.

On a connecting itinerary, pack for the strictest carrier on the ticket rather than the first one. The sizer at the second gate does not know what the first one allowed.

The direction of travel is consistent across sources, even where the exact numbers are not.

Travel press through 2026 reported that Ryanair raised the bonus paid to ground staff for identifying an oversize cabin bag at the gate to about €2.50 per bag in November 2025, up from about €1.50, and removed the monthly cap. Ryanair has not confirmed those amounts, so treat the figures as reported rather than official. What is consistently described, and what matters to you, is that checking got stricter rather than looser.

The passenger side has been surveyed too. A European consumer study found that about a third of all baggage charges were levied at check-in or the boarding gate, averaging around €45, and that 38 per cent of respondents had a compliant bag forced into the hold.

So this is a routine outcome rather than bad luck, and planning for it is not paranoia.

There is still a cheaper move available right up until you join the boarding queue, and it is to solve the problem at a different counter.

On Ryanair the bag-drop desk charges a flat price: €35.99 for a 10 kg checked bag and €59.99 for 20 kg. Against €70 to €75 at the gate, the desk is the cheaper answer for the same bag, and it is the only place where a walk-up purchase is a fixed number rather than a penalty.

The catch is the clock. The desk sits before security and closes well ahead of the gate, so this only works if you notice early.

On Wizz Air the arithmetic runs the other way. A hold bag bought at the airport is €70 to €80, while the cabin bag penalty at the airport or gate is €55 to €65 and ends with the bag in the hold regardless. Neither is good. The cheaper of the two is the penalty.

A bag can fail two tests at once and be billed for both, which is worth knowing before you decide to risk one of them.

On Ryanair, excess weight on a checked bag is €13 for each extra kilogram, charged at the airport, the call centre or a kiosk. That is separate from any size penalty.

On Wizz Air the excess is €13 to €15 per kilogram, per item, per flight, and the airline words its advice plainly: weigh your bags before you arrive, because the surcharge applies to a bag sitting between two of its weight tiers.

flydubai stacks its charges explicitly. Its gate fee for non-compliant hand baggage is charged on top of any excess baggage fee already paid at the check-in desk, so the same passenger can be billed twice on one flight for two different bags.

A bathroom scale at home costs nothing and removes the whole category.

Luggage marketing is the quiet cause of a good share of these fees, because the labels lag the rules.

Ryanair enlarged its free under-seat bag during 2025, from 40 x 20 x 25 cm to 40 x 30 x 20 cm, about a fifth more volume. Plenty of retail listings still advertise the older, smaller spec while calling it Ryanair size. Ryanair's own fare bundle article writes the current size with the axes reordered, as 40 x 20 x 30 cm, which is the same volume and adds to the confusion.

The phrase cabin approved on a product page means nothing on its own, because it names no airline and no year.

So buy to three numbers. Write down the size for the airline and the bag type you are flying with, then check the product's stated dimensions against it. If the listing gives only a litre figure, it is not telling you what the gate will measure.
