Here we go again. I have decided that a potential way of locating where AR13 sent from LAX is to compare the international flight routes from LAX from 1pm to minight for both American Airlines and United Airlines. This is based on reports that teams were in both of those those terminals, although that certainly does not guarantee that my method of analysis will lead anywhere useful. Let's see.
So, I start with the American Airlines international(excluding Canada) schedules for nonstop and direct flights from LAX. There are a myriad of connecting flights to everywhere, so in order to put some boundary on this analysis I have limited it as stated. That does prove to be somewhat limiting, since American flies lots of routes to Europe and to Latin America from O'Hare, DFW and Miami, but very few from LAX. Here is where it does go:
Monterrey, Mexico (2)
Tokyo - Narita
OK, now it's time to overlay the United Airlines schedule for only those cities for 1pm to midnight departures onto the above. Here is what gets eliminated:
Hong Kong is also eliminated for having flight arrivals 11 hours apart, which is too far for fairness to the teams.
Here are the AA and UA schedules in thet designated time frame for the remaining cities(Note that most AA flight are 4 digit code-shares that are not operated by AA. Also note that I have allowed some UA connections to match up with AA nonstop/direct destinations rather than just eliminating them.):
Auckland - AA7337 2045 0505+2, UA9549 2145 0530+2, UA9545 2230 0615+2
Beijing - AA5790 1330 2320+1, UA4456 0140 0520+1 (Note: this departure is 12 hours later, arrival is only 6 hours later and little is open in the interim, so this could work even though departure is after the allowed window)
Briisbane - AA7298 2320 0605+2, UA839/9507 SYD connection 2226 0955+2, UA9545/9595 AKL connection 2230 1055+2
London Heathrow - AA136 1800 1225+1, AA134 2030 1450+1, UA934 1311 0740+1
Melbourne - AA7356 2340 0755+2, AA7337 2045 0815+2, UA9595/9543 AKL connection 2230 0950+2
Mexico City - AA8301 1320 1855, AA8303 1745 2320, UA817 1335 1916
Monterrey - AA8311 1610 1740, UA5436 516 1638, UA5437 1815 1937
Sydney - AA7364 2030 0605+2, AA7366 2350 0725+2, UA839 2226 0610+2
Taipei - AA7967 1635 2155+1, UA891/UA9683 NRT connection 1259 2050+1
Tokyo Narita - AA5829 1320 1640+1, UA 9685 1255 1625+1, UA891 1259 1631+1
So, where does that leave us. My hunch is that teams landed in Melbourne, but it could also be Sydney or Auckland, all of which were early in the morning of April 24. It is now the morning of April 25 in New Zealand and Australia, so it could be difficult to catch up with them.
