I took this on an 11 day trip to europe. It survived being checked and rolls nicely. You get a little bit of extra room since the wheels are inset, although it seems like you're losing some space due to the top being rounded. The expansion feature only seems to give you another inch to an inch and a half, which is less than in other pieces of luggage I've had, but it's possible that it's still a carry on size when expanded.
