Ontario INTERNATIONAL Airport

At least in our country, some airports are designated as "international" airport. The criteria appears to be "if a flight from another country has ever landed at your airport, it's international."

The international airport is not CURRENTLY required to provide international service. If it were, then Ontario's airport would have to go through a dizzying round of name changes, as service between the airport and Mexico starts, stops, then starts again.

Ontario is currently NOT receiving any international flights, but it will definitely be international beginning on November 20:

Aeromexico will resume international flights at Ontario International Airport starting in late November.

According to the airline's website, the first flight from Guadalajara, Mexico, should arrive Nov. 20 at 11:45 p.m. and depart from the Inland airport the next day at 1:15 a.m. Fares for the flights linking Ontario and Guadalajara range from $138 to $253 each way, according to the site.

The Press-Enterprise article notes that Aeromexico had stopped its service in February, expected to start it again in July, but won't actually start until late November.
