Questions

Is 55x40x23 cm a cabin bag size?

It fits the carry-on limit on 9 of 28 airlines: Southwest, Frontier, Allegiant, Sun Country, easyJet, British Airways, Wizz Air, Jet2 and Air Canada. It’s too big for American (4 cm too wide), Delta (4.4 cm too wide), United (4.4 cm too wide), JetBlue (4.4 cm too wide), Alaska (4.4 cm too wide), Hawaiian (4.4 cm too wide), Breeze (4.4 cm too wide), Avelo (4.4 cm too wide), Ryanair (3 cm too deep), AirAsia (4 cm too wide), Malaysia Airlines (4 cm too wide), Batik Air (4 cm too wide), Singapore Airlines (3 cm over the total), Scoot (3 cm over the total), Cathay Pacific (4 cm too wide), WestJet (4 cm too wide), Jetstar (4 cm too wide), Qantas (4 cm too wide) and Virgin Australia (4 cm too wide).

Can a 55 × 40 × 23 cm bag go under the seat?

No: it’s bigger than every published under-seat limit, the largest being 48 × 34 × 23 cm on Qantas. It has to go in the overhead bin.

Is a 55 × 40 × 23 cm bag free to take on board?

Free in every fare on Southwest, British Airways and Jet2. Free except in the cheapest fare on Air Canada (Economy Basic). On Frontier, Allegiant, Sun Country, easyJet and Wizz Air it’s a paid cabin bag: only a smaller under-seat bag is free. On Delta, Alaska, Hawaiian, Batik Air, Cathay Pacific and Jetstar it’s over the carry-on limit and no under-seat size is published, so it’s free only if it fits under the seat in front of you. On American, United, JetBlue, Breeze, Avelo, Ryanair, AirAsia, Malaysia Airlines, Singapore Airlines, Scoot, WestJet, Qantas and Virgin Australia it’s too big for the cabin and would have to be checked.
