Loreto International Airport

Loreto International Airport carries the IATA code LTO — the three letters printed on boarding passes and baggage tags — and the ICAO code MMLT, used in flight plans and by air traffic control. It serves Loreto, Mexico.

IATA codes are assigned by the International Air Transport Association for passenger-facing use; the four-letter ICAO code encodes region and country and belongs to the operational side of aviation.
