Nevada-based Allegiant (G4) is a low-cost carrier that flies all Economy Class aircraft to about 100 destinations in 40 US states. On many routes, it only operates a couple times a week, and it typically flies to smaller, regional airports. However, Allegiant's focus cities include a mix of smaller and larger airports, including Bellingham International Airport (BLI), Fort Lauderdale–Hollywood International Airport (FLL), Los Angeles International Airport (LAX), Las Vegas's McCarran International Airport (LAS) and Phoenix–Mesa Gateway Airport (AZA).
