Hey, i`m wondering about buying a plastic 20х30х40 bag with pull-off wheels.
I`m sure that ryanair checking frame is 22x32x42, so these sizes 100% fit.
BUT i heard that people who flewn by Wizzair have had to pay extra, because their 20х30х40 bags actually don`t fit a free-check-frame.
Somebody could or already had measured real Wizzair frame sizes?
Please, lemme know!
