I fly professionally very often and this Samsonite suitcase is my faithful companion. There is room for everything that I need for 3-4 days, it is super light, rolled very well and has all hand luggage racks of all types of aircraft space. As luggage, so to check in, I would not let it go, because it is not a hard case simple and the material could possibly be torn by sharp objects (such as on a conveyor belt). It may well be that it is more stable than it looks, but as I said: For me, he's just hand luggage.
The little one has already some times around the world on the puckel and still looks like new. Would buy it again at any time.
