Allegiant Air, the low-cost airline that caters to leisure travelers in small cities, is asking the U.S. government for approval to operate flights to Mexico.Allegiant filed an application with the Department of Transportation on Tuesday to fly twice a week between Las Vegas and the Mexican cities of Hermosillo and San Jose del Cabo.

The company said in the filing that the flights would begin around June 1, 2014 and use 166-seat McDonnell Douglas MD-80-series jets from its current fleet.
The flights would run year-round, not just seasonally, and Allegiant asked for authority to operate them for at least two years.
