Booking Error

[Jblee803]

For the last two days I have been trying to book a trip. I cannot get past the flight section. It doesn't matter what day or what time the flight (I have changed it just to see if that'll work).

The Concur error GDS 20904 is a generic profile move error from the Global Distribution System (GDS, like Sabre) when booking travel, often due to invalid or incomplete traveler profile data, such as special characters, incorrect frequent flyer numbers, or missing legal name/DOB. To fix it, check your Concur profile for errors, remove any special characters, ensure all fields (name, DOB, contact, loyalty programs) are complete and correctly formatted, then try booking again; if it persists, contact your company's travel admin or agency for support.
