What I can add (as of today....)
With regard to the MDs, they are around for a while. 9 are leased and 17 are owned outright. Two leases expire next year and one in 2007 with no plans to renew. After that they expire at the rate of 1 or 2 a year through 2013. As mentioned, to get out of the leases would be expensive. The last number I heard was around $200M. There is no current market for the ones we own. When the recent aircraft order was placed, there was no provision for Boeing to buy out any leases or otherwise take any of the currently operated aircraft. Instead the company negotiated very attractive terms for the new 737-800s. Plans are being made to make some upgrades to the navigation platforms in both the aircraft and the sim. While anything can change at any time, the current plan is to continue to operate the MDs for some time to come.
As to the new bid...it should be out in a week or two. The numbers I heard today were 60 new positions from one source and 80 from another. We have been told in training to expect 8 crews per month (on both fleet types) beginning in Oct. This is going to put sim time at a premium, especially on the 737, beginning in Jan. They were still talking today about how to manage the required sim time.
The projected block hours for 2006 for the MD fleet remains about the same as this year, even though the 2 aircraft previously mentioned will be going away. The projected block hours on the 737s for next year are increased over this year's, reflecting planned growth and additional aircraft.
Again, anything can change...and probably will. But this is what I hear as of today.
