remember they didnt hire for two years, they are getting into 07 with a 6 year upgrade, it will take some time as they hired alot in 07 into 08, but mid/early 08 it stopped till 2010. So when they get through 08, which is 5 years, it will drop. With the 824 it COULD be early next year they are through 08. If that were the case, it would drop to a 4 year upgrade and we did not hire many in 2010, the next big chunk was 11. I think by next summer it drops a good amount.
Until the next turd sandwich comes of course. However there is a reason they are packing the classes right now. They could hire 500 by this time next summer, looking back to the start of this year, that is a good amount of upgrades, esp with us being fat on FOs right now.
Just playing a what if game, but IF the 824 goes, and goes at the expected rate, the upgrade time is going to plummet, esp with United hiring and Delta getting ready to get back into it, as well as AA.
