UA originally did not intent to use the 762 on transcon services- the intended routes were one-stop transcon service such as NYC-DEN
......wow, have times changed. The airlines that placed the original orders for the 767-200 had short/medium haul ops in mind, which explains the large orders by AA
(which had limited international service at the time), AC
(for intra-Canada and transborder flights) and even Pacific Western.
Some interesting trivia......DL
had the option to "convert" its 767-200 aircraft to 767-300s, by converting I mean sending the aircraft back to Boeing to be lengthened and streched to -300 standard; DL
never took up the option and the 15 762s remain with DL
in their original form (also, from what I hear, their original interiors and are looking a bit worn at the moment).
Western did order 6 examples of the 767-200, as mentioned above, and converted the order to 737-200s which made more sense for their route system. The 737-200s were among the last of the type built, and were actually delivered after Western had received some 737-300s (WA placed a small order for the 733). Most of the subject 732s are still flying for Delta today....first mainline, then Express, and now mainline again.
When launched, the 767 was considered a "medium haul" airliner intended for routes up to about 2000 miles, fitting into an airlines fleet between the DC10/L1011 and the 727-200; DL
flew its first examples on NYC-FLorida and ATL
routes and the ability of the 762 to operate out of LGA
was a prime concern......the idea of the ER
types came later on, along with the idea of flying this twin jet overseas. The ER
types really saved the 767 program and the 767 became much more of a 707 replacement (in mission) that a 727 replacment (in mission).
