Love my Mono Carry on Plus!
I had my first trip overseas with my Mono for 10 days. It was a a perfect set up for my entire trip ( land + boat). I had no problem store my mono on an overhead bin ( even on a smaller carrier). I also bought the Metro Duffel with fits perfect with the Mono. You easily navigate the inside of the plan as the wheels rotate accordingly. Highly recommend buying both as a pair!
