Allegiant airlines. I made reservations for a family member. A week before the flight he was unable to go. I called Allegiant prior to the flight. The problem, I was on hold over an hour, then it kicks you out. Called again, and again. No answer. I set my alarm one night to call, still no answer. All you get is Sorry we have lots calls, try again later or stay on hold. tired for 4 days before I was able to talk to someone. Out of the 400.00 spent, my family member received a 70.00 voucher. Customer service was rude, told me hurry up he had other calls to take. He said you didn't buy flex plan (which was not affordable) and I didn't cancel within the seven days. I told him I would have if they would answer their phones. I also lost all the money from the Alamo rental. I used Allegiants website to book it, I did all the work, when I talked to allegiant they told me I had 24 hours to cancel FROM the time I made the reservation in April. Why would I cancel 24 hours back in April (cost 141. to Allegiant). DO NOT BOOK cars, hotels, anything extra on their web-site if you cancel you LOOSE all your money. I would NEVER book another flight with them, I would be better off, paying the extra 100.00 on another airline. Terrible service.
