I recently purchased this set and traveled to SouthAmerica for 2 weeks, we flew a total of 8 fligths and the luggage handled wonderfully! I used the small tote as a diaper bag and it made my life easier. I think it depends on the way the luggage is handled at the airports and even the toughest luggage might end up damaged at one point. I also used a few samsonite pieces during the trip and those where the ones that ended up damaged. The 4 wheel system makes it a breeze to walk through the airport and very lightweight but plenty of room to expand. I highly recommend this set!
