Flight pax service tab is used to show requested materials via a PSM message. At the left side of the screen, a summary of requested services/goods can be seen. At the right side, there is the detailed information, which passenger at which seat requests what together with the transferring flight info if any.
Requested service information is also used by the 3rd party roster software.
Imported PSM messages updates the contents of this tab. In a future release, Celebris generated PSM messages will use the information in this tab, but currently no PSM message is automatically generated by Celebris.
