Allegiant cancelled my departing flight a week prior because they didn't have enough passengers. Then, cancelled my returning flight THREE HOURS before I had to leave with no explanation and no other option to book a new flight. Had to book a flight home with a different carrier for $700. Allegiant refunded me only $177. I am always understanding and willing to give companies another chance if they make it right but Allegiant couldn't have cared less. When asked about the fee my rental car company would charge me for the cancelled flight, they told me it was my problem. Absolutely NO ATTEMPTS TO REMEDY THE SITUATION. Absolutely unbelievable.
