Read the post above this one -- Jiminmem is absolutely right.
Since Compass was created people have been saying nonstop that the pilots there would be furloughed any month now due to mainline flowbacks. So far in this recession mainline just barely scraped by without sending anyone to the street. I am impressed at that, really, because so many other companies were not able to do that. Heck, look at UPS now furloughing in the face of an economic upswing! Unbelievable.
So, in return for 'keeping the seats warm' we see the flowthrough agreement about to work in the upwards direction.
I do agree with you -- the upward movement at Compass during this downturn has been a very unique situation. Bad times, but the place was created right before that started and very very few of the fNWA guys on the street took the opportunity to come back to CPZ before going all the way back to mainline, so they ended up needing new hires and of course there were some fast upgrades and such.
There is one more thing. You say that the people at Compass are a lucky bunch. In some ways, yes -- I mentioned those above. But when you examine the resumes of most of the pilots at Compass you would realize that although they are fortunate for the upward movement, very very very many of them had no opportunity to continue flying at their former employers, to include:
Gemini
ATA
Aloha
DHL
Continental
United
US Airways
NetJets
Comair
Midwest
Skyway
ExpressJet
The list goes on. Lucky, yes in some ways. But many would have stayed put if they could have. Fortunately, they found Compass and it's worked out alright so far (albeit an enormous paycut and QOL cut for most).
