I don't KNOW for sure, but what I would envision is when a pairing is dropped from CS to FLICA it will first go to a newly created holding window (pairing-specific waiting room) where it will sit for a set time, maybe 5 mins, while it generates an alert to all pilots who have set up an alert.

Then, when the timer for that pairing hits zero, it will drop into FCFS.

It would be like the opening seconds of the monthly FCFS but it will happen continuously for each new pairing dropped to FLICA.

Still FCFS, doesn't require a contract change, and foils the Bot boys and FLICA refreshers who get pairings before the rest of the world ever knew they existed.
