I was able to buy one-way using laptops on Allegiant, but not a round-trip flight (it is a separate ticket because of multi-city). After trying to book the flight online 5 times, the goal with Google was to obtain Allegiant Airs phone numbers so that I could make a call-in booking instead. This was my first time booking by phone, so this did not feel weird as I figured they were simply trying to make sure that I was the cardholder of the card that I booked on. Guests After suffering through the same frustration everyone else has had with the Allegiants site failing to complete the checkout, I eventually signed off of my account and entered it all by hand, including the credit card information (which I have read helps with further down).
I spent the past 90 minutes entering guest information in 3 browsers, my phone, on an app, using 2 different credit cards, and could not get Allegiants system to finalize a purchase. Guest has Googled solutions online (use the app, purchase 2 singles, not using the credit card with the saved), tried these without success, and there is 2 hours waiting for their 800-number. Passengers may submit a specific request to change their Allegiant Airlines name, both with their Reservations Team as well as Customer Service, for appropriate guidance on making an appropriate change.
