We use spirit all the time. We get to bypass Pittsburgh and fly out of the local airport 15 miles from us. All of our flights have been direct. Never any lines, free parking and security usually takes less than 10 minutes. So far we've had zero complaints. That is, not until our flight back home from the other airport.they always show up as the cheapest airfare, but the flights are like 16 hours including layovers
I can't stand a 2 hour layover, there is no way in hell I'll ever fly with them
