the ignorance and misinformation in this thread is astounding...

there are grandfather clauses
there is a section detailing that the last 20 of the standing order of 175s are slated for pdt, as are the first 20 options (if AA exercises the order options)

it would take aag 120 days to close us down and transfer the majority of our flying to existing contract carriers (with the exception of a tiny handful of routes that would disappear) and they would most certainly do it as it would let them really put the screws to eagle(sorry, they're never going to be 'envoy' to me)
