Last time Comair got planes was Summer 2005... we got a couple 50s back from SKW (I believe they went there during the strike in 2001) and this "growth" tripped our two-year pay freeze. Of course three months later Delta surprisingly "went bankrupt" and the 30+ planes we were promised to bring us to the Contractual 199 Aircraft Fleet just "went away". They did let us keep the pay freeze, though.

Then in Jan 2006 a bunch more went back to lessors. Then more went away with the RFP in 2006-2007. Meanwhile Delta is leasing planes to Freedom and SKW for $1.00 a month.

Then in 2008 we were awarded the Freedom 900s and a week later we weren't. But everyone still remembers that one.

I believe you are correct- a Displacement Bid is downgrades and base reductions and such.

If they were adding 700/900 flying to JFK, or adding a DTW/MEM base it would be a Vacancy Bid.
