Registration request

I need the registration of an American Airlines 737-800 with 30L on the nose landing gear doors. Route was CUN-MIA

Thanks.

Hey,

American Airlines doesn't have 737-800 with the fleet number 30L. The only one which looks like 30L is 3DL.
30100 1022 B737-823 CFM56-7B27 12/20/01 AMERICAN AIRLINES (SILVERMINE RIVER) N978AN

Take care,
