No, BBB is referring to Captains. There will always be an MD base in SDF. And the numbers will always be up there. Europe (including) the middle East will be much easier served by planes flying out of SDF rather than ANC. Everyone seems to think that ANC is the new thing. Well in a way, it is, but the square footage of the sort facility in SDF is probably more than the combined size of every building on the ANC airport. ANC was only done because of crew efficiency.
However, AV80R if you want to bid MD-11 SDF remember that you really can't be displaced after your first year. There may be a little play with the last few on the list, but for the most part fleets are growing and the required number of FO's is going up. The MD is the way of the future, the way of the future, the way of the future (couldn't resist). UPS will have just shy of 40 airplanes (????) within short course and they aren't all going to ANC. My prediction........SDF MD- 180/250, ANC MD- 220/300. Finally, if you look at the shifts and changes in the fleet seniority lists, there really isn't a lot of movement. What this means, is that when somebody upgrades at UPS from the panel to the front, they pretty much stay in that fleet/seat for a while. Very few move around from fleet to fleet after their intital upgrade. There is a little back and forth from Z to MD, but for the most part people sit tight. Bottom line, if you bid the MD, and you are # 180, chances are that won't change much unless there are upgrades, but you will never go back all too many. If you consider that there will be more 767 flying in Europe and every 767 going over the Atlantic is essentially stuffed, the MD will be big and beautiful for a long time in SDF. Finally, they are still short about 60 FO's on the MD in SDF.
