What is DTX?
DTX is the commercial passenger code for McKinney National Airport's new terminal — the code Avelo Airlines and flight-search sites use for bookings starting November 11, 2026.
What is TKI?
TKI is McKinney National Airport's longtime FAA identifier, used for general aviation, corporate, and training aircraft. It continues to apply alongside DTX.
Which code should I search for flights?
Use DTX when searching for commercial flights, once Avelo's booking engine goes live. TKI is not used for passenger ticketing.
