Six flights 10 planes no problems
I traveled light on a 25 day trip to France, Spain and Ireland. I never checked a bag and this backpack was never challenged as carry-on luggage and fit easily in every overhead bin. I flew United, EasyJet, Vueling, Aer Lingus, Alaska, and Air France. There was only one bus trip where the overhead bin was too small, but there was plenty of room
