Looking for the best carry on bag for Jet2? Every passenger gets a free 56×45×25cm overhead bag and a free 40×30×20cm under-seat bag on every fare, so you’re covered for up to 10kg of hand luggage without spending a penny on extras.
The question is which bags are worth buying. We’ve researched the market across both allowances and picked five that fit the sizer, pack well, and won’t let you down at the gate. Three cover the main 56cm overhead allowance, and two are built for the bonus 40cm under-seat slot.
Flight Knight 56×45×25cm 4-Wheel ABS Hard Shell
Best overall — 4.3★ · 6,400+ reviews
The Flight Knight is the most reviewed 56×45×25cm hard case at this price point. It holds 52 litres, weighs 3kg, and sits exactly within Jet2’s overhead limit, leaving plenty of your allowance for clothes and kit.
The ABS hard shell is scratch-resistant and water-resistant. Four spinner wheels give full 360-degree movement through terminals, and there’s a combination padlock included. Flight Knight backs it with a five-year warranty, which is rare at this price. Body dimensions, excluding handle and wheels, are 48×44×25cm.
Available in a wide range of colours. If you want the safest, best-tested option, this is it.
Aerolite 56×45×25cm 2-Wheel Softshell
Most packing space — 4.4★ · 1,196 reviews
If packing capacity is your priority, the Aerolite is worth the extra. At 60 litres, it holds 15% more than the Flight Knight despite being lighter at 2.6kg. The softshell construction gives a little when you overstuff it.
The two rollerblade wheels run smoothly on airport floors and the telescopic aluminium handle extends to a metre. There’s a front zip pocket for documents and headphones, and the interior is lined with fabric made from recycled plastic bottles. A TSA-approved lock is built in.
The best pick if you want to maximise packing space within Jet2’s 56×45×25cm allowance.
FLYMAX 56×45×25cm 4-Wheel ABS Hard Shell
Best value — 4.5★ · 485 reviews
The FLYMAX is the budget pick: a 4-wheel ABS spinner with 57 litres of capacity, a combination lock and a foam interior protector, weighing 2.8kg.
It has fewer reviews than the Flight Knight, but its 4.5-star rating is the highest of the three, and reviews consistently praise the price-to-quality ratio.
Flymax backs the case with a one-year warranty, and the shell is both water-resistant and scratch-resistant. It comes in twelve colours, from black and navy to pink and lime, easy to spot on the carousel.
| Bag | Max size | Cost |
|---|---|---|
| Overhead bag | 56×45×25cm | Free Included |
| Under-seat bag | 40×30×20cm | Free Included |
Cabin Max Anode 24L TwinWheel
Best wheeled under-seat case — 4.6★ · 16,381 reviews
The Cabin Max Anode is one of the most reviewed under-seat cases on Amazon UK, with over 16,000 ratings at 4.6 stars. It fits Jet2’s 40×30×20cm allowance precisely, with twin wheels and a telescopic handle.
Inside: a zipped divider, packing straps and a small organiser pocket for chargers. The ABS shell is solid without being heavy, and 24 litres is plenty for a few days’ essentials.
At 1.9kg empty, the Anode is one of the lighter wheeled cases in this size, leaving more of Jet2’s 10kg weight limit for what you pack. The textured ABS shell resists scratches better than a gloss finish, and Cabin Max backs it with a three-year warranty. It comes in colours from classic black to Rose Gold and Inca Green, easy to spot on a busy carousel.
Cabin Max Metz 40×30×20cm Backpack
Lightest option — 4.6★ · 1,466 reviews
If you’d rather carry a backpack than wheel a second case, the Metz is the obvious choice. At 0.6kg empty, it leaves 9.4kg for your main bag, and holds 24 litres in the 40×30×20cm slot.
It’s made from recycled rPET polyester, with compression straps, a water bottle holder and a trolley strap for attaching it to a suitcase handle, working well as a day bag once you’ve landed.
The best carry on bag for Jet2: our verdict
For most passengers, the Flight Knight 4-Wheel Hard Shell is the safest choice for the main overhead allowance: 6,400+ reviews and a five-year warranty. If you want more capacity and don’t mind paying a little more, the Aerolite Softshell gives you 60 litres in a lighter bag. If you’re watching your budget, the FLYMAX does the job for around £40 with the highest rating of the three.
For the under-seat slot, the Cabin Max Anode TwinWheel is the standout with 16,000+ reviews at 4.6 stars. If you’d rather save the weight for your overhead bag, the Cabin Max Metz Backpack at 0.6kg is the better call. Once you’ve got your bag sorted, our guide to flying with Jet2 covers everything else, from check-in to seat selection.
“People assume Jet2’s free cabin bag is too good to be true, but it isn’t. The only thing that catches passengers out is the physical sizer at the gate, not some hidden charge.”

Jet2’s cabin bag allowance explained
Jet2 allows every passenger two free cabin bags on every fare: an overhead bag up to 56×45×25cm and 10kg, plus an under-seat bag up to 40×30×20cm. No priority boarding is needed.
This is a real advantage over Ryanair, which charges for a cabin bag on standard fares. With Jet2, you board with a full-sized case and a separate day bag without paying anything extra. It’s worth checking how Jet2 compares with the rest of the market on our UK airline hand luggage comparison. See the official Jet2 hand luggage policy for full details.
All dimensions include handles, wheels and external pockets. Jet2 uses a physical sizer at the gate, so a bag even slightly over in any dimension may be sent to the hold at extra cost. If you’re flying a different airline, our Ryanair carry-on guide, Wizz Air carry-on guide, TUI carry-on guide and British Airways carry-on guide cover the same ground for each airline’s own allowance.
Frequently asked questions
What size is Jet2’s cabin bag?
Jet2 allows one overhead cabin bag up to 56×45×25cm (maximum 10kg) and one under-seat bag up to 40×30×20cm. Both are included free on all fares.
Can I take two bags on Jet2?
Yes. Jet2 allows two cabin bags per passenger: one in the overhead locker (56×45×25cm) and one under the seat in front (40×30×20cm). Both are free on all fare types. You don’t need priority boarding.
Does Jet2 weigh cabin bags?
Jet2 has a 10kg combined cabin luggage weight limit. The size sizer at the gate is the more frequent check, but the 10kg limit is enforced. All five bags in this guide weigh under 3.5kg empty, giving you at least 6.5kg for your belongings.
Do I need priority boarding to take a cabin bag on Jet2?
No. Unlike Ryanair, Jet2 doesn’t require priority boarding to take a bag into the overhead locker. Both the 56×45×25cm overhead bag and the 40×30×20cm under-seat bag are included free on all fares, regardless of when you board.
