Flight Knight: cabin cases sized for Ryanair, easyJet and more

Shopping at Flight Knight? See all current Flight Knight discount codes and deals, checked regularly.

Flight Knight is a UK luggage brand from Prime Brands Group, a business that ships from its own warehouse in Hertfordshire. Its main selling point is simple: cases built around the published baggage sizes of the airlines most UK holidaymakers fly with, so you can pick a bag that fits the sizer at the gate.

It suits budget-airline regulars trying to avoid extra bag fees, families kitting out for a holiday, and anyone who wants a matching set without paying premium-brand prices. The website has a 'Shop by Airline' menu covering Ryanair, easyJet, British Airways, TUI, Jet2 and Wizz Air, plus a 'Shop by Size' menu.

What's worth a look

Here are six picks from the cases, sets and backpacks on the site.

The 40x20x25cm Travel Backpack is designed for Ryanair's free personal item and has a built-in USB-A port, a TSA lock and a sleeve for a 13-inch laptop. If you're buying for the whole family, the BUBBLE 3-Piece Suitcase Set combines a 55x35x20cm cabin case with medium and large hold cases, all on eight spinner wheels.

The SAFIR V2 range is the brand's core line. It comes in a long list of colours and in sizes from a 40x30x20cm underseat case up to a large 29-inch hold case. Other styles include Aluminium, Bubble, Curve, Print, Silver and a deeper Trunk shape, and there are soft-shell options if you prefer a case with outside pockets. Suitcase sets come in hard and soft shell, and you can also filter sets by cabin size if your airline uses an unusual allowance.

Product pages for the sets list the capacity and weight of each case. That's handy if you're trying to stay under a hold-bag weight limit, as a lighter empty case leaves more room for packing.
