Before Covid I used to fly European short-haul fairly often for business reasons. On a typical 1-3 night trip I would always take my carry-on spinner case because I could fit everything in it I needed. Very convenient.
All the different airlines have slightly different dimensions allowed, by a couple of cm each way but no-one ever checked. What is the point of carry-on if you can’t carry it on?
Everything is getting worse, isn’t it?
