I was flying to MCO from Vegas this week and the FA started her credit card pitch by saying " How many of you had to pay for your carry-on at the gate"? Now I don't know what sort of" pay for the bag show" took place for my flight because I was the first to board, but at the gate next to mine going to St Louis, there was a hot exchange that took place involving a passenger who must have been one of those professional fight club guys. He was pulling his gloves out and trying to wear them to reduce the bag volume, and he was refused entry. This guy looked like he could do some damage. So here we are on my flight and this FA is stirring up the pot reminding passengers that they got charged that carry-on fee. Tone deaf as they come, in my opinion , because someone who feels they were cheated is not going to be conducive to paying more to support the airline. She stated that having the credit card will save the passenger the carry-on fee, which we know is not true since you have to reach an Elite status to receive that perk and the credit card is a means to that end. Correct me if I am wrong, but doesn't United give travelers a free bag if they use the United credit card to buy the ticket.? I know my Delta card has that perk, up to 9 suitcases. But I do not think the Frontier card does. Am I wrong on that?
