Which airline has the cheapest ticket prices?

Some of the cheapest airlines in the United States include Southwest, JetBlue, Spirit and Allegiant Air, but there is not a single airline that is always cheapest. Costs vary according to time and location.

Some airlines, such as Spirit, charge extra for baggage, drinks and food. This allows the airlines to charge less for the basic ticket, but passengers should consider these extra fees when determining which airline is cheapest. Other airlines, such as Allegiant Air, only fly to and from select cities, so they may not be available for certain trips. Passengers should also consider personal comfort levels aboard a plane, as more comfortable seats usually cost extra.
