Backpacks

Ryanair allows one small personal bag free of charge for all passengers, with a maximum size of 40x30x20cm. The Flight Knight 40x30x20xcm backpack is sized to that exact allowance and fits under the seat in front of you. If you are travelling on a Priority or flexi-plus fare, you can also bring a larger overhead cabin bag - the 55x40x20cm backpack falls within Ryanair's paid overhead allowance of 55x40x20cm. Always verify the current allowance on Ryanair's website before you fly, as policies can change.
easyJet allows all passengers one free cabin bag measuring up to 45x36x20cm, which must fit under the seat in front. The Flight Knight 45x36x20cm backpack is sized to fit that allowance exactly and has been tested in the easyJet free cabin bag sizer. If you have an easyJet Plus, FLEXI or Up Front/Extra Legroom seat, you can also bring a larger overhead bag - in which case the 55x40x20cm backpack may be suitable depending on the exact overhead allowance for your fare. Check easyJet's website for the current policy before travel.
Wizz Air allows all passengers one small bag measuring up to 40x30x20cm free of charge, which must fit under the seat. The Flight Knight 40x30x20cm backpack is sized to that allowance. Passengers with a WIZZ Go fare or above can also bring a larger overhead cabin bag - the 55x40x20cm backpack falls within Wizz Air's larger cabin bag allowance. Always check the Wizz Air website for the most up-to-date policy, as fare inclusions and size limits can change.

Yes. The 55x40x20cm size sits within the overhead cabin bag allowance for a number of major airlines, including Ryanair (with Priority boarding or above), Wizz Air (WIZZ Go fare or above), British Airways, and several other carriers. As a backpack rather than a rolling case, it functions as a carry-on alternative and goes into the overhead locker. The specific fare type you book will determine whether this size is included free or requires an additional fee, so always check your airline's baggage policy before travel.
Yes - all Flight Knight backpacks are designed as hand luggage for use on flights.
