The pilots waited til they were going to have work overtime then told us they needed to stay in vegas. This all occurred after the flight was delayed AND then after we were already all boarded on the plane. We all had to deplane and wait for new pilots to come fly us. It was terrible logistical planning and staffing inefficiencies on the part of Frontier.
