I use Allegiant because I'm based in Rapid City for six months out of the year. I regularly get $39 and $59 tickets to LAS or Mesa. I build in a day then use SWA or someone else to fly elsewhere. I FedEx my luggage and avoid carry-on fees (I just say they are medical supplies; they really are; deoderent, toothpastes, etc, never had an issue with this). I pay the extra $11.50 to bank my segments (avoiding any change fees) and 'splurge' for a window seat on the left side of the MD-80.

They really are a lifesaver to many in the area. The only other option is drive to DEN or pay extortionist type fares on the big guys.

Normal people fly G4. They're not all bus riff-raff.
