Leisure carrier Allegiant Air will discontinue two city pairs next month: Santa Barbara, California-Las Vegas and McAllen, Texas-Los Angeles.
Both closures come "due to lack of market demand", Allegiant president and CEO Maurice Gallagher Jr. says in a statement.
Flights between Santa Barbara and Las Vegas will end after 13 September, just over a year after Allegiant inaugurated the route in May 2008.
Allegiant plans to nix operations between McAllen and its newest base, Los Angeles, after 20 September, just four months after launching the city pair this May.
Allegiant has not announced where it will reallocate aircraft, an airline spokeswoman says.
