United announced in Onboard Updates that Flight Attendant Scheduling and Support (FASS) will, on a monthly basis, evaluate reserve coverage and increase trip trade for open flying allocations accordingly. Our contract provision (9.G.4.) requires the daily allocation to be at least 3% of the active flight attendant population, up to a maximum of 70 slots.
Over the last few months, FASS has been testing this new system. This past May, the allocations were increased by an average of 33%.
According to Onboard Updates, here's how the process will work:
If a trade is rejected because it exceeds the open allotment and the allocation is later increased, you must enter a new request for the trade to be reconsidered.
