Private fares for your office, seat availability and the\nodd commercial dispute do the rest.\n\n![Infographic: Lufthansa Group's extra charge per ticket by channel, six reasons a flight differs between GDSs, and a table of which airline sells through Amadeus, Sabre, Travelport and NDC](\u002Fmedia\u002Fwhy-flights-show-in-one-gds-but-not-another\u002Finfographic.png)\n\n## Who decides what a GDS shows?\n\nThe airline. A GDS (Amadeus, Sabre or Travelport) shows what each airline has agreed to distribute through it, on\nthe terms of that airline's contract with that GDS. Three airlines can sit in the same GDS on three different\ndeals.\n\nTravelport's help pages describe three levels at which an airline or other vendor can take part: a **direct\nreal-time link**, with instant availability and confirmation; **regular updates without an instant link**, where\nstaff must message the vendor to confirm; and **no direct link**, where both availability and confirmation go by\nmessage ([Travelport, \"Vendor Participation Levels\"](https:\u002F\u002Fsupport.travelport.com\u002Fwebhelp\u002FGWS\u002FContent\u002FOverview\u002Ftravel_processes\u002FVendor_Participation_Levels.htm)).\nThe other GDSs work with similar levels under their own names. So an airline can show live seats in one system and\na delayed or partial picture in another.\n\n## Why are some fares only in NDC or on the airline's website?\n\nBecause airlines want you to book them there. NDC lets the airline build the offer itself, and some airlines keep\npart of their fares out of the classic (EDIFACT) GDS channel:\n\n- **American Airlines** removed about 40% of its fares from EDIFACT channels on 3 April 2023 and made them NDC-only\n  ([Cranky Flier, 27 July 2023](https:\u002F\u002Fcrankyflier.com\u002F2023\u002F07\u002F27\u002Funited-starts-to-follow-american-by-pulling-fares-from-traditional-third-party-channels\u002F)).\n  In June 2024 it began returning fare content to the GDSs, but basic economy stays NDC-only\n  ([Business Travel Executive, 13 June 2024](https:\u002F\u002Fwww.businesstravelexecutive.com\u002Fnews\u002Famerican-tells-agencies-it-has-begun-returning-fare-content-to-legacy-gdss\u002F)).\n- **United** took Basic Economy fares (US domestic and short-haul Latin America) out of EDIFACT channels from\n  5 September 2023 ([Cranky Flier](https:\u002F\u002Fcrankyflier.com\u002F2023\u002F07\u002F27\u002Funited-starts-to-follow-american-by-pulling-fares-from-traditional-third-party-channels\u002F)).\n- **Turkish Airlines** keeps \"NDC-only promotional fares\" and its rich content for agencies connected to TKCONNECT,\n  its NDC platform ([Business Travel Executive, 16 May 2024](https:\u002F\u002Fwww.businesstravelexecutive.com\u002Fnews\u002Fturkish-airlines-launches-new-ndc-platform\u002F)).\n- **Lufthansa Group** gives a \"Base Offer\" through NDC in the GDSs and a \"Smart Offer\" through its direct\n  (\"bilateral\") NDC model ([Lufthansa Group DCC Guideline, valid from 1 January 2026](https:\u002F\u002Fbusiness.lufthansagroup.com\u002Fcontent\u002Fdam\u002Fb2b\u002Fexperts\u002Ffiles\u002FLHG_DCC_Guideline_01JAN26.pdf)).\n  So two channels show two different sets of fares for the same flight.\n\nWhether you see NDC fares in your GDS at all depends on your office.

Travelport's checklist for missing fares names\nthe usual causes: the agency's office (PCC) isn't added to the private fare's security; the fare's sales\nrestrictions don't match where and how you sell; the currency or passenger type is wrong; or the account code isn't\nentered ([Travelport, \"Missing Fares\"](https:\u002F\u002Fsupport.travelport.com\u002Fwebhelp\u002FFaresAndPricing\u002FContent\u002FMissingFares.htm)).\nThe same logic applies in every GDS: a negotiated fare loaded for one agency's office won't show for another\nagency, even in the same system.\n\n## Why do seats and connections differ?\n\nTwo more reasons, both about how a GDS builds what you see:\n\n- **Seat availability.** With a direct real-time link the GDS asks the airline live; without one it shows the\n  airline's last update, which can be out of date (the participation levels above). A class shown open may then\n  fail when you sell it.\n- **Connection building.** Minimum connecting times are agreed data sets: the airport sets a default and airlines\n  file their own exceptions. OAG handles over 157,000 of them, \"used by global distribution systems (GDS) and\n  connection builders\" ([OAG, 12 July 2023](https:\u002F\u002Fwww.oag.com\u002Fminimum-connection-time)). Each GDS's low-fare search\n  also caps how many options it returns: Amadeus's Flight Offers Search returns at most 250\n  ([Amadeus API specification](https:\u002F\u002Fgithub.com\u002Famadeus4dev\u002Famadeus-open-api-specification\u002Fblob\u002Fmain\u002Fspec\u002Fjson\u002FFlightOffersSearch_v2_swagger_specification.json)).\n  So two systems can build and keep a different set of connections for the same trip.\n\nAirlines also judge seats by the whole journey, not flight by flight, so a connection must be sold as one trip.\nSelling it one flight at a time can be refused, or fined later.\n\n## Why does an airline disappear from a GDS?\n\nA commercial dispute between the airline and the GDS:\n\n- Sabre removed all **Turkish Airlines** content on 1 September 2024. Turkish bookings could no longer be serviced\n  in Sabre, so ticketing, reissues and cancellations went to the airline\n  ([Travel Market Report, 30 August 2024](https:\u002F\u002Ftravelmarketreport.com\u002Fair\u002Farticles\u002Fsabre-drops-turkish-airlines-from-distribution)).\n  Turkish content returned to Sabre under a new deal in June 2025\n  ([Travel Bulletin](https:\u002F\u002Ftravelbulletin.com.au\u002Fnewsroom\u002Fsabre-kisses-and-makes-up-with-turkish-airlines\u002F)).\n- **American Airlines** sued Sabre in January 2011 over its display and booking fees.
