For those of you who have flown Skybus before, are they really strict with their carry-on sizes? I was able to get the $10 seats for two different trips this summer. We are going to my daughter's dance competitions and will have her dress with us. Although the bag is flat, it is bigger than their "allowable" dimensions. It does fit in the overhead bins though.
I'm trying to figure out if they will allow it or not. Checking the dress is not an option.
