DETROIT - Sept. 17, 2026 - Frontier Airlines ( Nasdaq: ULCC ) announced its latest growth at Detroit Metropolitan Wayne County Airport (DTW) today, with nonstop service to New York's LaGuardia Airport (LGA) beginning later this fall. The new service, which will offer daily flights between Detroit and New York during the peak holiday travel period, marks Frontier's latest growth at DTW as it expands to offer routes formerly operated by Spirit Airlines.

Frontier is also increasing its frequency of service to Fort Lauderdale-Hollywood International Airport (FLL), Tampa International Airport (TPA), Orlando International Airport (MCO), and Miami International Airport (MIA). With its growth in operations, the airline is projected to offer 41% more total available seats for sale from DTW in March 2027 compared with March 2026.

To celebrate, America's Low Fare Airline is offering fares starting at $69.*
