I had ordered a gluten-free meal through you I double triple checked that through you got screamed at by one of your representatives. She yelled at me and said that she had ordered the mail, she had chosen my seat, and made sure that all my baggage is were paid for. That was a lie. My experience with discover airlines in and of itself was GOOD but your representative was out of line did not do anything that she screamed at me and told me she did and I literally had to call the airlines myself to get my seat selected to double check on my gluten-free meal which still was not on board and to pay for my bags which I thought that I paid for all of them until I got to the airport and I still had to pay for my check back. So cheap flights I will never use you again.
