Tijuana International Airport (IATA: TIJ, ICAO: MMTJ), officially known as General Abelardo L. Rodríguez International Airport, is the primary international airport serving Tijuana, Baja California, Mexico, and one of the most important aviation hubs in northwestern Mexico. The airport is located approximately 8.86 kilometres east of downtown Tijuana, immediately adjacent to the United States border.
TIJ is a unique binational airport. The main facilities — including the main terminal, runways, and apron — are located on Mexican soil, but the airport is directly connected to a terminal on the U.S. side in San Diego via the Cross Border Xpress (CBX) pedestrian bridge. The CBX bridge spans 120 metres and takes approximately 15 to 30 minutes to cross on foot, allowing U.S. travellers to walk directly from the San Diego side into the Tijuana airport to board their flights without passing through a traditional land border crossing.
The airport is operated by Grupo Aeroportuario del Pacífico (GAP), which has managed it since 1999 and carried out major expansions following the 2002 privatisation concession. TIJ is a major hub for Volaris, which began operating in Tijuana in 2006 and has since developed the airport into a hub connecting more than 35 destinations.
In 2025, Tijuana International Airport served 12,650,000 passengers (including CBX users), ranking as the fifth busiest airport in Mexico. This comprised approximately 8.56 million domestic passengers and 4.09 million international passengers. CBX users totalled approximately 4.02 million during the year, including approximately 1.9 million travelling from the U.S. into Mexico and 2.11 million travelling from Mexico to the U.S.
