I recently flew GIG-GRU-JFK on AA 772 and JFK-SEA on AA 752. I asked the FAs for the registrations but they didn't know. I wonder if anyone here would know.
The GIG-GRU-JFK flight was #950, left GIG on Jun 26, 2004 at 18:25. The FA didn't know the registration, but what he did know was that this wasn't the triple-seven that usually does the GIG-GRU-JFK route, but one of AA's Asia/Pacific 772s.
The JFK-SEA was #199, scheduled to leave JFK at 07:30 but left late at 08:15, on Jun 27, 2004.
Thanks in advance.
