I've just returned from the US and managed to get the registrations of all the aircraft I travelled on except for one - an American Airlines MD-80 series (82?) from Denver to Chicago. Because of the aircraft positioning at the gate I couldn't get a proper look at the registration, and the crew could only tell me it had the tail number "4YG".
I've tried looking up all the databases I know of, but can't tie this fleet number to an actual N- reg. Can anyone help?
Thanks
