Flex instructor who bumped my CA this week said they were told "potentially the biggest bid in FedEx history, 900+ movements."
Jim Bowman was telling crew members in the AOC during the MEM Christmas party "very large bid, bid what you want because you're probably going to get it."
An LCA I recently flew with said they want to get guys in the aircraft where they're going to stay a long while instead of ... for example ... a low-mid seniority FO going to the 777, training on it, then leaving it on the next bid to go to 757CA.
Another flex said, big bid. After that, expect smaller bids using the new vacancy system in the TA.
