DI arrived at Orlando airport in the morning to find long line to check in. I proceeded to the line to check in. After standing line for two hours, the Frontier employee advised my planed had already left. She told me to go to another line to change my ticket. I was able to get another ticket, but the new flight was scheduled until 8. Then the flight was delayed to 10 pm , and then the plane changed to 1159pm. I am pissed. User's recommendation: Don’t fly Frontier Airline.
