If required, you can easily add project codes to your flight and/or hotel bookings. This will be added to a respective booking's invoice.
To do so, make a search and flight/hotel selection as you normally would. At the bottom of the final trip summary page you will see a project code drop-down menu. Start typing the project code name and select the correct one when it appears. Alternatively, you can also create a new project code by clicking on Create a new code. Confidential project codes will not have project names (descriptors).
Then simply proceed with the booking and the project code will be automatically added to the reservation.
Note: Your company account must have project codes activated to enable this functionality. Please speak to your administrator.
