The luggage tags flex and the ID cards come partially out during airline baggage handling.  They are also not as easy to see as I expected when trying to retrieve luggage from the airline carousel. I dismissed one of the four suitcases I was trying to retrieve until the 3rd or 4th time it came around because I was sure it was not ours because the bright orange luggage tag was obscured from view (the handle came out first and was resting against the lower ledge of the carousel.
