Currently en route to GVA from PDX via EWR. Seated in 2 E on an A319. Taking my 75 L pack for a five day trip in Chamonix. Both a petite woman and FA made comment of the size my backpack in the overhead bin, as I had to place it lengthwise (rather than the wheels first position if I were using a duffel or carry-on luggage piece). I felt like I was being made to feel guilty, but frankly I paid good money for my Z class ticket. I mean, the GA didn’t stop me and tell me to check it, so why should I feel bad, right? Or am I wrong? Any thoughts would be appreciated.
