You can really get specific when it comes to marketing terms in the pre-jumbo and jumbo introduction years. Not only were the aircraft "named" (i.e. Whisperjets/Whisperliners), but particular runs were labeled, as well. UA
's flights to the Florida and the southwest US were called "Sunbirds," National's 747's were "Sun Kings," UA
's service to Hawaii was billed as "The Royal Hawaiian" regardless of A/C, and PS
's L1011's were called "Mother Grinning Birds." Their narrow bodies were simply "Grinning Birds." TW
had their "Royal Ambassador" service, PA had their "Clippers" and "The President Special (FC) and Rainbow Service (YC)." JA
had their jets billed as "Jet Couriers," and BA
(then BOAC) had their "Speedbirds."
The various marketing tools went beyond names. The terms were on menus, special service items such as stationary, movie programs, and inflight magazines. It all added some glamour to flying. If you flew coast-to-coast, you flew American's Mercury service, United's Red Carpet, and TWA's Ambassador. It really made flying something special and not the cattle cars of today.
