We use Spirit out of Atlantic City at least once a year. As a matter of fact, we just returned on a Spirit flight on Friday. Our trip was smooth in all aspects. Only once did we have a problem. There was a problem with a plane and they needed to bring in another one from Detroit. Ths meant a delay of 16 hours - yes - 16 hours! However, they gave each of us free round-trip tickets, plus $100.00 vouchers on future flights. Every couple of hours, they gave us food vouchers to be used at the airport. It was a bad situation. But, at least they made up for it...and they did NOT allow us to get on an unsafe plane. We have flown with them many times since then and have never had a problem. They have a new gate at the Orlando airport which is also an improvement from when they shared gates.
