Good bag - don't use it as a P/I on Flair
"I can confirm Flair will not allow this bag as a personal item due to the structure of it. I just recently flew Flair from Waterloo to Nova Scotia and decided to take a chance with this bag. . . . no luck. . . cost me $175 as a carry on round trip. My son used my Osprey Daylite 26+6 which looks just as big, but because it was a soft backpack, they accepted it as a personal item."
