FWIW;
DAL is looking at a 100 seat jet for mainline. It is fact, and they know they need it sooner than later. They may decide to continue to sit on their hand like they have for the past five years, but the guys in route know that this RJ fix is killing them. Watch for significant pull down of the DCI fleet as soon as the contracts expire, and a new mainline platform can be found.
As for the NWA pull down effecting everyone. I hate to say it but no amount of complaining will change it. We are a WE not a them or us. We will all take the pain. That is why it is all being done after SOC. There is a point to that.
A lot of this stuff will be absorbed with new metal that is announced and newer metal that is not announced. Suffice to say we got lots of jets coming so just wait. We need the economy to truly turn around before the publicly ink deals for billions of dollars in jets.
As for the 767. There is strong talk of parking the GE 767-300 domestic birds. No time frame has been given but they will not be around like the ER's will be. They are looking at 20 years for those. They are also looking at parking the 32 5500 series 757's. That probably will come in the next three years, but there will be metal and mergers to deal with at that. (Hope the merger does not happen and with SWA playing games it might not but who knows) The 30 and 40 series 9's will be parked.
Now what replaces it? There are a lot of options. The deal of the day is the 90's and there are a lot of them to be had. The acquisition process for each of these is time consuming so to raise the fleet to 35 total and then get board approval for more will take time. The 100 seat jet is probably a few years away. I say 2012 to 2013 to commensurate with the 9 going to VCV. You also have a few 73N's that we have options for that MAY get exercised, but that is not a first or second option. In fact, at this time they do not want any more. (See if that lasts). Airbus is making some very good offers for 320's and 330's. I am sure if we wanted four engines they would do that too. Boeing is working with the 787-800 issue and I would expect to see an answer on that after SOC. Maybe before, but it depends on the lawyers. There will probably be 777-300's here before the end of 2010 to start replacing or augmenting the 744 lift.
In essence a lot is going to happen in the next four to six years.
As for bases, and fleet movement. A lot of people that are new to DAL are for the first time dealing with the prospect of getting booted out of a base. Some of us are not. Problem is that it is uncharted water for many folks. They will get through it, but they have to point of reference. My advice is to bid a jet that gives you the QOL of life you want, no matter what the base is. After 2012 there are going to be retirements that will open a lot of doors. We are not talking about the rest of your DAL career, only the next four to six years. It really is not a lot of time. It is less time than many of your brethren were on the street.

As for me Bar, if mid 30's is young what does the mid 20's equate too? You had a career change. I am sure that it will be better than people's worst fears.
On a good note, the plan is changing and for the better. Wait and see, I am sure it will change again in six weeks.
