Sixty seven (?) training starts on the 777. About a half dozen started in October so they'd perhaps only impact the Thanksgiving holiday. The other 60 ish starts made have had training conflicts with Thanksgiving and/or Christmas. Granted they were relatively junior already but IMO that supports the point I was trying to make - senior guys avoid the holiday conflicts if they can and there frequently can be significant back filling after a bid status goes very junior.

The junior FO's on the 777 in DFW, who were on reserve in November, are line holders in January. Guys just senior to them, who've been saying "I'd like to go to the 777 but I don't want to be on reserve" are suddenly going "whoa, did you what they're holding now?" With a couple more Europe trips (most popular to second most popular flying?) the mid pack guys are looking at more bidding horsepower.

And that's just at the bottom of the bid status. How many BNA, MEM, IND, etc, etc commuting to a G2 job have become DFW 777 lineholders as the bottom moved 2500 numbers? A lot. G4 pay changes bidding/vacancy thinking.
