As far as I've heard its more like at least 3 years. Alaska is slowly phasing out the MD-80s with the last one to leave the fleet between 2005 and 2007. I've just read that here and there, so I can't verify it, but the numbers do speak. Alaska has I believe 32 MD-80s and 71 73S/4/G/9s and AS is planning to operate a summer schedule slightly over capacity in comparison to 2001 and they aren't recieving 30 737s with in the next year. Please, how would they pay? I mean AS is better off than most, but still, thats almost a 1/3 of the fleet to be replaced. The MD-80s will be around for a little while more, please, don't rush it. Do you want more 737s in the world?
