Dave, I have a couple of problems with that letter. First of all there is no Continental MEC for the flight attendants. There is only one union now (AFA). Second, there is no Continental Micronesia flight attendants anymore. They were merged into mainline some time in the last year or so when their certificate was merged into Continental's.
This letter may be accurate, but not for the current situation. It sounds like the situation of a couple of years ago though, so maybe that should be the date on the letter.
