On the East Coast, several European airlines are candidates and I seem to remember BA operating fifth freedom to Mexico. Let's go with BA LHR-IAD-MEX certain days of the week with a 747. I also think I remember LH operating its FRA-BOS flight to various points beyond (i.e. PHL certain days of the week). So, let me guess that the final flight is LH FRA-BOS-MEX with a 747 Combi.
JAL did fly a TYO (HND or NRT?) - YVR - MEX later.
I have differing opinions besides LH FRA-BOS-MEX 747 Combi. Mine are:
KLM DC8 AMS-IAH-MEX with local traffic rights for Houston - Mexico City
and two probably wrong answers
British Airways VC-10 LHR - JFK - GDL (Guadalajara)
British Airways 707 LHR - IAH - MID (Merida)
