Japan - I'm heading to Japan

I'm heading back to Japan to go to the Fuji Rock and Summer Sonic music festivals and then to hang out for a couple of weeks.

Flying United this trip. This trip is a little different because instead of flying directly to Tokyo from LAX, I'm flying to San Francisco, switching planes and then flying to Tokyo. Coming back I fly directly to LAX.

The Jet had a flat tire that they were changing before we boarded. I wonder if they have AAA roadside assistance?
