IMHO--

More than a few MD 11 FOs are going to bid 757 Captain. But they aren't going to talk about it. They don't want the word to get out and cause an avalanche of more senior bubbas to bid it above them, possibly locking them out of it. Ditto for Airbus FO's. Perhaps more of them.....

757 CA will go relatively senior. 757 FO will go junior with 727 FE's and newhires.

Newhires will come onboard later this year with 727 FE, 727 FO and 757 FO as class assignments. I guess more MD11 ANC assignments at the beginning, again.

If they plan it well, fewer FE assignments will be available than usual or they will go near the end of the cycle.

I wonder how many over 60 DC10 FE's will come over to the 727?
