I saw that too. However, I called AA pretending I had a friend on that flight. "Patty" told me that flight 621 landed just moments ago at LAX. The flight originated from Minn to Dallas to what is listed as Orange Co but Patty "confirmed" that the flight landed at LAX. I asked her for flight 621 taking off on 11/27 but she could not access flights from that date. Weird...
Is the airport at Orange Co. considered a part of LAX? I know I'm reaching here but...
SNA is close to LAX but doesn't use the same radio frequencies or flight paths. The aircraft would not fly over the ocean entering to or departing from SNA.

Interesting, your post about inaccessibility of plane information. BTW, John Wayne Airport, located in another county (Orange), is NOT part of LAX, which is situated out by a beach city, Santa Monica, a part of Los Angeles County.
