re: Allegiant Air

Their primary business model is to provide affordable direct routes from smaller regional airports to popular destinations like Vegas or Orlando.

They're great because a person can fly direct and cheap from places like Shreveport or Fayetteville without a connecting flight through a major hub like DFW, Houston, or ATL.

They fly older planes, charge for everything, and often only have 1 flight/day without any other flights or planes available if a problem occurs with your plane.

Delays are common. The good thing is it's a direct flight, so a 45 minute delay won't cause you to miss a connecting flight.
