Well, technically there isn't anything preventing Phil from taking the 30th night flight out of Santiago, along with the rest of the teams. It's happened before quite a few times, especially when flights are few and far between, like they are here between Santiago and Auckland.
A pointless piece of information that belongs in the air schedules thread, but since you guys brought it up here... There is indeed a set of flights that can get Phil to Santiago before 1725 on the 30th:
5L 210 from La Paz to Santa Cruz: 0830 to 0930
5L 210 from Santa Cruz to Buenos Aires: 1045 to 1430
AC 93 from Buenos Aires to Santiago: 1600 to
1720Hey, I did say "pointless" right?
But come to think of it, these could explain Justin's "two waves" of racers coming into Santiago Airport!
