I had entered my TSA number, confirmed with the telephone representative that it was on the ticket, and it did not print on my ticket. I had to go through the security line twice. I was charged $74 to check in a bag, and $60 for a carry-on. For round-trip, this adds $260 above the cost of the ticket. For a 1.5 hour flight. I will never fly Spirit Airlines again.
