About the British Airways row. BA have withdrawn the hand baggage allowances page we used to read, and now publish the figure through an interactive baggage calculator instead of on a page we can link you to. The figure shown is the last one we read from them, on 13 September 2026, and we have left it here because it is more useful than a blank. Treat it as the last known figure rather than a checked one, and confirm it in BA's own calculator before you fly.

One bag, unless you buy Priority

Wizz Air run the strictest of the arrangements in the table above. The free carry-on is the only bag you bring into the cabin. The trolley bag that goes in the overhead locker comes only with WIZZ Priority.

That makes the under-seat bag more important on Wizz Air than on almost any other carrier. It is not your second bag, it is your bag.

Wizz Air also say the free carry-on cannot be checked in free of charge, so if it does not fit at the gate you are paying to put it in the hold.

Ten kilograms in a bag that size

Wizz Air are one of only two carriers here that publish a weight for the small bag. Theirs is 10 kg, against easyJet's 15 kg. The other four state a size and leave weight alone.

Ten kilograms inside 40 x 30 x 20 is not a limit most people will reach with clothing. It is reachable with books, tools or camera gear, and it is worth knowing that the number exists because the bag is the only one you are carrying.

What counts as a separate item

Wizz Air allow a coat or blanket, a mobile phone, reading material for the flight, duty free bought after security, and for infants, food and a foldable stroller or small crib. A pair of crutches for a passenger who needs them.

A neck pillow is specifically not a separate item. Wizz Air say it has to fit inside your cabin bag, and that if it does not it can be treated as an extra item and charged. That is unusually specific and it catches people out.

Before you buy anything

Measure it the way the gate does

  1. Pack the bag the way you will actually fly with it. An empty bag measures smaller and tells you nothing.
  2. Flatten the straps against the back panel. Gate sizers make no allowance for a strap sticking out.
  3. Measure the widest point of each face, handles and pockets included. Not the fabric panel, the whole object.
  4. Compare against the airline you are flying, not the one you flew last time.

Questions about this allowance

What size bag is free on Wizz Air?

40 x 30 x 20 cm and up to 10 kg, one per passenger, and it must fit under the seat in front of you. Read from Wizz Air's own cabin baggage page on 14 September 2026.

Can I take a second bag on Wizz Air?

Only with WIZZ Priority, which adds a trolley bag for the overhead locker. Without it the free carry-on is the only bag you bring into the cabin.

Is there really a weight limit?

Yes, 10 kg. Wizz Air are one of only two carriers in the table above that publish a weight for the small bag, the other being easyJet at 15 kg.

Does a neck pillow count as a separate item?

No. Wizz Air state that it is not a separate free item and must be packed inside your cabin bag. If it does not fit it can be charged as an additional item.

What happens if my bag does not fit at the gate?

It goes in the hold and you pay for it. Wizz Air state that the free carry-on cannot be checked in free of charge, so there is no version of this that does not cost money.
