Travel writers and editors have rigorously tested a selection of backpacks to determine which ones officially fit under the seats of budget airline flights, helping travelers avoid extra baggage fees.

Testing Methodology

The testing process involved evaluating backpacks against the luggage restrictions of airlines such as Ryanair, Easyjet, and Wizz Air. Each backpack was packed with as much as possible to assess its capacity and practicality for short-haul or budget flights. Durability, comfort, and the ability to compress or conform to specific dimensions were key considerations.
