The JetBlue reservations system is slated to cut over from Navitaire to SabreSonic Jan. 29, a move the airline says will bring enhanced capabilities for travel agents through the Sabre, Travelport and Amadeus global distribution systems.

However, despite the changes, travel agents using their GDSs to access JetBlue still — for now, at least — will lack basic functionalities that consumers take for granted when booking JetBlue.

JetBlue, in a FAQ [pdf] for travel agencies, says the switch to Sabre as the host for the airline’s reservations system brings the following improvements in the GDSs for travel agents: last seat availability, better inventory and fare capabilities, and “industry-standard e-ticketing.”
