Hello fellow Canadians I'm an FA for Air Canada... I don't know all the details for the booking, free ungrades etc etc etc... Flight number 1800 are "charter" flights... usually it's flight going out once a week... I know for Cancun it's not a charter flight since we have a flight every day and during winter we have 2... Now, let's talk about the clloset... it's so small that your dress won't even HANG... and we are taking stuff in and out of that closet during the entire flight so... My suggestion is (the same i'm giving all the happy brides boarding our flights) flat on top of the bags in the overhead bins...
