I have had 2 flights booked with this airline and both got cancelled at the last minute. It looks like they cancel when they don't have enough passengers booked. Yesterday I was booked MCO-GSP and got a text about 2 hours before flight that it was cancelled and to read the email about what todo. I have still never received any email from them about the cancellation. I had to book a last minute flight on another airline and am out over $500 because of this useless airline. Again save your money and don't book with Frontier.
