Also, you can do what I do.....park at the border ($5/day) and walk across the border to the Tijuana airport (literally on the border) and take the Aeromexico TIJ-NRT direct flight. Also flies from MEX-TIJ-NRT.....makes for a good mileage run. ie....ATL/SLC/LAX/JFK-MEX-TIJ-NRT and return.

The flight exists solely for the Mexican factories in Baja California (and Japanese tourists going to MEX).

Very convenient for SoCal peeps. No visa issues arise. Mexican tourist visa included in the airfare for your return.
