McKinney National Airport (ICAO: KTKI, FAA LID: TKI), formerly known as Collin County Regional Airport at McKinney, is a public use airport located in McKinney, Texas, approximately 30 miles north of downtown Dallas. Although most U.S. airports use the same three-letter location identifier for the FAA and IATA, this airport is assigned TKI by the FAA but has no designation from the IATA (which assigned TKI to Tokeen Seaplane Base in Alaska). The airport also has on-site vehicle rental as well as US Customs services for international flights.
