I would guess that whatever estimate for when the Brookfield crews would show up would be just that. It looks like at least one of the -200's has arrived at the paint shop, however I suspect (with good first hand information) that it will be after Feb before even one of the -200's are ready to ferry.
Your comments are the first I've heard about the -200's being "sea level airport planes". Makes sense, of course, that they aren't ideal at high/ hot airports.
I'd love for you to post some first hand experiences of life on the line there. It doesn't seem plausible that we Brookfield pilots would fly the -700's if they are physically are separated at a separate base, not to mention contract issues.
