These are the best carry-on backpacks – tried by the Good Housekeeping team
These are the backpacks our editors stash under airplane seats

These days, it’s not just the weight of your suitcase or the size of your cabin bag that you need to think about when you’re travelling by air. You also need to make sure your extra bag or backpack will fit underneath the seat in front of you.
And if you’re flying with an airline that even charges for an overhead carry-on, then having a backpack with room to cram in all your necessities and outfits (so that you’re not wearing a hundred layers on your flight) is essential.
To solve this packing conundrum, we asked the Good Housekeeping team – all frequent flyers – to tell us what backpacks they always travel with. Here's our list of best buys:

What size bag can I fit under an airplane seat?
The smallest carry-on restrictions come from Ryanair, which only allows a bag that measures 40 x 20 x 25 cm as part of the ticket price. This must fit underneath the seat in front of you, and there are fairly hefty additional fees to put luggage in the overhead lockers, not to mention the hold.
Other key under-seat airline restrictions to note include EasyJet (45 x 36 x 20 cm), WizzAir (40 x 30 x 20 cm) and British Airways (40 x 30 x 15cm). We detail all the main airline luggage restrictions in our detailed suitcase buying guide.
Below, you'll find a mix of sizes, including some that precisely meet Ryanair's stringent requirements, and others that may squeeze under, provided you don't fill them to the brim. Ultimately, it's worth picking the one you'll get the most use out of.
