Finding the best carry on bag for Wizz Air starts with one rule: every passenger gets a free personal item, maximum 40×30×20cm, that must fit under the seat in front. Wizz Air enforces this strictly at busy gates — choose the wrong bag and you will pay £12–20 each way. For a larger 55×40×23cm overhead bag, you need to add WIZZ Priority to your booking.
This guide covers the best carry-on bags for both allowances. All five products below were verified in stock on Amazon UK in June 2026.
| Bag | Allowance | Size | Price | Rating |
|---|---|---|---|---|
| Cabin Max Manhattan 24L | Free bag Free for all | 40×30×20cm | ~£25–30 | 4.6★ |
| BAGZY Foldable Duffel | Free bag Free for all | 40×30×20cm | ~£16 | 4.6★ |
| Aerolite Holdall | Free bag Free for all | 40×30×20cm | ~£10 | 4.6★ |
| Aerolite Expandable 2-Wheel | WIZZ Priority Paid add-on | 55×40×23cm | ~£43 | 4.6★ |
| Aerolite Hardshell 4-Wheel | WIZZ Priority Paid add-on | 55×40×23cm | ~£33 | 4.5★ |
Wizz Air bag allowance explained
Every Wizz Air passenger, regardless of fare type, gets one free personal item measuring up to 40×30×20cm. There is no weight limit stated for this item, but it must genuinely fit under the seat — Wizz Air do use bag sizers at the gate on busy routes, so a bag that is only marginally over can get pulled.
Buy WIZZ Priority (from around £6 per flight when booked in advance, higher at the airport) and you can also bring a cabin bag of up to 55×40×23cm into the overhead locker alongside your free personal item. Without Priority, that larger bag has to go in the hold, which typically costs more than Priority itself. Full carry-on rules are on the Wizz Air website.
If you also fly Ryanair, our Ryanair cabin bag guide covers a similar allowance structure — both carriers require Priority to use the overhead locker.
The best carry on bag for Wizz Air: free bag allowance (40×30×20cm)
1. Cabin Max Manhattan 24L — best all-round backpack
The Manhattan has been the top-selling 40×30×20 cabin bag on Amazon UK for several years. It measures exactly 40×30×20cm, holds 24 litres, and uses a structured clamshell opening so you can pack it flat. The rigid shape means it holds its dimensions consistently, which matters when a Wizz Air employee holds up a sizer at the gate.
It is made from recycled RPET fabric, has a dedicated padded laptop sleeve, and comes in a range of colours. More than 16,000 Amazon UK buyers have reviewed it at 4.6 stars. At around £25–30, it is not the cheapest option but it is the one most likely to last several years of regular use without the zip giving way.
Best for: travellers who want a structured backpack that works reliably trip after trip.
2. BAGZY Foldable Duffel — best mid-budget holdall
The BAGZY is designed specifically with Wizz Air in mind and measures exactly 40×30×20cm. The main selling point is the foldable construction: empty, it packs down to almost nothing, which is useful if you are travelling with a larger suitcase and want to fold the bag away on the return trip rather than managing two separate pieces of luggage.
At around £16, it costs less than half the price of the Manhattan. More than 2,100 buyers have reviewed it at 4.6 stars and it carries three sustainability certifications. It has a shoulder strap, top handles, and a front zip pocket for boarding passes and anything you need during the flight.
Best for: travellers who want a packable holdall under £20 that folds down for easy storage when not in use.
3. Aerolite Holdall — best budget option under £10
If you need something that meets the Wizz Air dimensions and costs as little as possible, the Aerolite holdall is the clearest choice in this guide. At around £10, it is the least expensive option here and it does exactly what it needs to. The bag measures 40×30×20cm, weighs around 600g, and comes with an adjustable shoulder strap, a lockable main zip, and a front document pocket.
Aerolite has been making airline-approved bags for years and their dimensions are dependable. This bag is rated 4.6 stars from 321 reviews. For a short trip or as a secondary bag, it is a sensible buy at the price.
Best for: one-off trips, budget travellers, or anyone who wants the cheapest compliant bag.
Best bags for WIZZ Priority (55×40×23cm)
4. Aerolite Expandable 2-Wheel — best soft-shell trolley
The Aerolite Expandable soft-shell trolley is built specifically for airline priority cabin allowances. In standard configuration it measures 55×40×20cm — within the free bag limit for some carriers — and expands to 55×40×23cm, the maximum for Wizz Air Priority. The 3cm expansion adds meaningful packing capacity for longer trips.
At around 2kg, it is light for a wheeled cabin case. The soft shell compresses slightly when you are forcing it into an overhead locker that is already half-full, which the hardshell version below cannot do. Two spinner wheels handle airport floors well. More than 2,000 buyers have reviewed it at 4.6 stars and it is approved for Ryanair Priority, Jet2, British Airways, and other European carriers as well as Wizz Air.
Best for: frequent travellers who want a light, flexible trolley that works across multiple airlines.
5. Aerolite Hardshell 4-Wheel — best hardshell trolley
The hardshell version uses ABS plastic rather than soft fabric, giving your contents more protection. It expands from 55×40×20cm to 55×40×23cm, matching the maximum Wizz Air Priority allowance. Four spinner wheels are noticeably easier to handle than two wheels through a busy terminal, and the rigid outer shell means the bag holds its shape properly in the overhead rather than slouching.
At around £33 in charcoal, it currently comes in slightly cheaper than the soft-shell version — Amazon pricing on this category moves around. It has 1,400+ reviews at 4.5 stars. For anyone who prefers a hardshell and wants the full Priority allowance, this is the pick.
Best for: travellers who prefer the protection and rigidity of a hardshell case with full Priority allowance.
Frequently asked questions
What size is the Wizz Air free bag allowance?
The Wizz Air free personal item must not exceed 40×30×20cm. This applies to all fare types. The bag must fit under the seat in front of you.
What size bag can I bring with WIZZ Priority?
With WIZZ Priority, you can bring a cabin bag of up to 55×40×23cm into the overhead locker, in addition to your free 40×30×20cm personal item.
Does Wizz Air check bag dimensions strictly?
Yes. Wizz Air uses physical bag sizers at the gate on many routes and particularly on busy flights. A bag that is marginally over-size or obviously overpacked can be pulled and charged at the gate rate, which is much higher than buying Priority in advance.
Is 40×30×20cm big enough for a week?
For two to three nights, a 40×30×20 bag is workable if you pack carefully. A full week of clothes and toiletries will not fit. If you are going for a week, WIZZ Priority and the 55×40×23cm allowance is the practical option.
