The Frontier Airlines LGA Terminal can be found at New York City’s LaGuardia Airport (LGA). Terminal A is also known as the Marine Air Terminal. Because it is smaller and less crowded than other terminals at LGA, passenger experiences are more efficient. Frontier offers pay-as-you-go flights; additional fees apply for checked baggage and preferred seating. Frontier links LGA with multiple US cities. Terminal A provides quick security checks, basic amenities, and limited dining and shopping options. There are shuttles, taxis, and public transportation options for visitors.
