Just a note-we had some nice luggage that the wheels fell of off too, due to the airlines handling. Not Mickey, but some nice pieces. Our big one is now unusable. So, I think it could happen to anything, but it sounds as if it happens more with Mickey luggage. Too bad, I would like some too!
Oh yeah I'm sure ours came off because of the airline handling as well, goodness know they aren't gentle. The problem with our was it wasn't just the wheel it was the whold plastic thing that attaches the wheel to the suitcase. That's why we couldn't get it fixed because there was no where left to attach a wheel to. I have had good luggage and cheap luggage but I haven't ever had luggage just fall apart on me like this did.
Having said that it is very cute luggage but for the price we paid, almost $100,I would have like something a little better made. We just replaced all our mismatched luggage with a Samsonite set from Costco for $150 three pieces with those wonderful wheels that turn 360* hopefully thus can survive baggage handlers!
