This article got me into the fascinating rabbit hole of airline websites for travel agencies. It turns out most airlines have one, and while some content seems to be gated behind contracts and login walls, a lot of it is just out there. Compared to the consumer-focused sites, there's a lot less marketing fluff and a lot more industry lingo (which Google and/or a frontier model can usually help you with). Most of the content is just weird aviation trivia; those sites won't let you book a flight, but you will learn a lot of minutiae about how an Amdeus PNR looks like, how to indicate that a passenger is carrying human ashes in Sabre, or what order an agent needs to make bookings in. Some interesting things I found, in no particular order: https://www.lufthansaexperts.com/shared/files/lufthansa/public/mcms/folder_102/folder_3212/folder_4631/file_136168.pdf https://www.lufthansaexperts.com/shared/files/lufthansa/publ... https://www.lufthansaexperts.com/shared/files/lufthansa/public/mcms/folder_6672/file_153087.pdf https://www.lufthansaexperts.com/shared/files/lufthansa/publ... https://www.qatarairways.com/tradeportal/en/bookingnticketing.html https://www.qatarairways.com/tradeportal/en/bookingnticketin... https://support.travelport.com/webhelp/Smartpoint1P/Content/Air/Ticketing/Revalidating_ETRs.htm https://support.travelport.com/webhelp/Smartpoint1P/Content/... https://pro.delta.com/content/agency/us/en/site-map.html https://pro.delta.com/content/agency/us/en/site-map.html https://pro.delta.com/content/agency/us/en/policy-library/distribution-and-revenue-recovery/validation-to-sell-delta-plated-tickets.html https://pro.delta.com/content/agency/us/en/policy-library/di... https://air.flyingway.com/books/amadeus/Amadeus_Guide.pdf https://air.flyingway.com/books/amadeus/Amadeus_Guide.pdf
