Concur does not receive flight information directly from individual airlines. Instead, flight inventory is provided through the Sabre Global Distribution System (GDS), which is the booking platform used by the university's travel management company (CBT).
Airlines choose whether to distribute their flight schedules and fares through the Sabre GDS. When an airline participates, its available flight inventory is made available to CBT and displayed in Concur.
If an airline does not participate in the Sabre GDS, or chooses not to make certain flights or fares available through Sabre, those options will not appear in Concur and cannot be booked through the university's travel management company.
Once the flight inventory is available in Concur, the system applies the CSU travel policy to determine which fare types are eligible for booking. As a result, some flights or fare classes may appear in search results but not be eligible for booking if they do not comply with CSU policy.
There are several possible reasons:
The airline does not participate in the Sabre Global Distribution System (GDS). If an airline does not distribute its flights through Sabre, those flights will not appear in Concur.
The specific flight is not available through Sabre. Even if an airline participates in the Sabre GDS, not every flight or fare may be distributed through that system.
Your search criteria are limiting the results. Travel dates, times, airports, connection preferences, and other search filters can affect which flights are displayed.
Generally, yes. Airlines that participate in the Sabre GDS typically make their available flight inventory accessible through the system, allowing those flights to appear in Concur.
However, the CSU travel policy determines which fare types can be booked. While some fares may appear in your search results, they may not be eligible for purchase.
Examples of fare types that may be restricted include:
Business Class
First Class
If a fare falls outside CSU travel policy, Concur may prevent you from completing the reservation.
Seeing a flight does not necessarily mean it is an allowable booking.
If the fare selected is outside university travel policy, Concur will display the option but may prevent you from purchasing it. This helps ensure bookings comply with CSU travel requirements.
