Frontier Airlines is currently operating at Terminal 7 at JFK Airport. However, starting in 2026, Frontier Airlines will transition its operations to the newly constructed Terminal 6 (T6) at JFK. This move is part of a major redevelopment project at JFK Airport, and the new Terminal 6 will offer a modern, technology-driven experience with amenities like biometric-enabled self-service bag drop stations and a shorter walk from security to gates. So as of now, Frontier is at Terminal 7, but from 2026 onward, it will be at Terminal 6. Terminal 6 is still under construction but is designed to be a state-of-the-art terminal with enhanced passenger experience features. If you plan to fly with Frontier in the immediate future, your terminal at JFK is Terminal 7. For flights in 2026 and beyond, expect Frontier at Terminal 6.
