It allows the user to search for a PNR no matter where they are in the application and allows the user to see if and what PNR is open and immediately access actions about it (on mouse over). The PNR is the centre of TTS Consolidator activity so this area is always visible throughtout the application even if the user scrolls down. The sticky PNR search speeds up work and minimize mistakes.
Users can also import PNRs made in the GDS via Sticky PNR search. Learn more here.
