I'm strongly speculating that one of the earlier flights out of LAX to get to Shanghai contained Phil and production to get ahead of the teams. Got to keep that in mind, folks, Phil has mentioned in the past that in some legs, its a challenge to get ahead of the teams by enough time to film all of his stand ups for a leg so he can leap frog ahead of the teams for the following leg.
Since I don't know when the teams finished departing for LAX from Pasadena, I'm not going to guess which flight that might be.
