Good for FedEx. If the business is growing, why do you think DHL and UPS keep flying narrowbodies to MEX
? DHL flies a (terribly noisy) DC-8-61, and UPS flies a B752F.
Besides, I always see the DC8 over Viaducto Miguiel Alemán on approach well around 8AM - isn't that too late to match its competitors' arrival schedules?.
