Jet2 has one of the most passenger-friendly hand luggage policies of any UK airline. Every passenger, on every fare, gets a 56×45×25cm overhead bag AND a 40×30×20cm under-seat bag, both completely free of charge. That means up to 10kg of carry-on luggage before you’ve spent a penny on extras.
The question is which bags are worth buying. We’ve researched the best carry on bag for Jet2 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; two are built for the bonus 40cm under-seat slot.

Jet2’s cabin bag allowance explained
Jet2 allows every passenger to bring two bags into the cabin on every fare. The main overhead bag can be up to 56×45×25cm and 10kg. The second bag goes under the seat in front and can be up to 40×30×20cm. Both are included free, with no priority boarding add-on needed.
This is a meaningful advantage over Ryanair and Wizz Air, both of which charge for overhead cabin bags on standard fares. With Jet2, you board with a full-sized cabin case and a separate day bag without paying anything extra. See the official Jet2 hand luggage policy for full details. For a comparison, see our Wizz Air cabin bag guide.
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 asked to go in the hold at extra cost. Every bag in this guide fits within the official limits.
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, which can be useful on the return leg.
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. Body dimensions are 53.5×45×25cm excluding wheels and handle.
Designed specifically for the 56×45×25cm allowance used by Jet2, BA, and easyJet. The best pick if you want to maximise what you take on board.
FLYMAX 56×45×25cm 4-Wheel ABS Hard Shell
Best value — 4.5★ · 485 reviews
The FLYMAX is the budget option here, and it punches above its price. You get a 4-wheel ABS spinner with 57 litres of capacity, a 3-digit combination lock, and a foam interior protector. It weighs 2.8kg.
It has fewer reviews than the Flight Knight, but its 4.5-star rating is the highest of the three overhead picks. FLYMAX is a small British luggage brand and the reviews consistently praise the price-to-quality ratio.
If you want a proper spinner case with a hard shell and you’re watching what you spend, this is the one to look at.
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 and comes with twin wheels and a telescopic handle so you can wheel it through the terminal rather than carry it.
Inside: a zipped divider, packing straps, and a small organiser pocket sized for chargers and travel accessories. The ABS construction is solid without being heavy, and 24 litres is plenty for a few days’ essentials alongside a main overhead bag. The handle extends to 95cm.
Works as a standalone carry-on for very short trips or as a second bag alongside any of the overhead cases above.
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 of your total allowance for your main overhead bag. It holds 24 litres and fits the 40×30×20cm under-seat slot without fuss.
It’s made from recycled rPET polyester, with compression straps, a water bottle holder, and a rear trolley strap for attaching it to a suitcase handle. It works well as a day bag once you’ve landed, which makes it more practical than a wheeled case for city breaks.
If you already have a main suitcase and just need a solid second bag that doesn’t eat into your weight allowance, this is the one.
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.
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.
