Didn't parker last week state that they were going to need all the airplanes? Maybe he was commenting on the AMR order. Not sure..
Would imagine some would be for straight replacement, Send older planes back to lessor as new ones are available at more favorable terms. Think I remember US with the original AB order was getting them for X millions. They did some acct games where they would sell them to X company for 10mil profit a pop, then turn around and lease them back. or some crap. Instant profits.......Wall Street probably loved it....
