Has anyone used any of the Allegiant Air rewards? I believe that they do not count against your reward limit - is that right? I'd be interested in hearing about the free carry on, the advance seat selection, as well as the one where you get a free second flight if you book a package. I believe that the free flight is up to a value of $200 (which rarely covers the flight cost), but a savings none the less. But I was wondering if I book a package through Allegiant can I book it in such a way that I only book 1 night hotel stay through the package? (Allegiant lets you book packages where you can book hotel only for part of the stay). I'dd like to do that because as much as I want to access the second free flight, I have some good comp selection right right through Total Rewards. So, if I can book flight and only 1 night through Allegiant, then that would be worth the companion free flight.
