Question:
SABRE took years to develop. Did it take equally long to develop systems for competing airlines? For those using IBM platforms, could they use any code or designs for SABRE or were they propriety to American Airlines?
re: http://www.garlic.com/~lynn/2008i.html#19 American Airlines there was airline control program (ACP) that was (vendor) operating system used for many of these online systems .... wiki page http://en.wikipedia.org/wiki/Airlines_Control_Program there was long period of development of the ACP operating system as well as the customer applications built on the operating system. In some sense SABRE is a brand which is a whole bunch of online applications that were (initially) built on ACP. Some number of the other airline res "systems" were also whole set of applications built using the ACP operating system. Currently, some number of the applications have been migrated to other platforms. circa 1980 or so ... there were some number of other kinds of institutions using ACP ... which led to renaming ACP to TPF (transaction processing facility) ... wiki page http://en.wikipedia.org/wiki/Z/TPF from above: Current users include Sabre (reservations), Amadeus (reservations), VISA Inc (authorizations), Holiday Inn (central reservations), CBOE (order routing), Singapore Airlines, KLM, Qantas, Amtrak, Marriott International , worldspan and the NYPD (911 system). ... snip ...
