I predict Delta and NW will merge and use the BK courts to merge the seniority lists, dump both retirement programs and write a new (sucky) contract. They will dump all of NW dc-9's order some airbuses and and furlough about one third of all employee groups. Many pilots will be furloughed but massive retirements will mitigate the long term damage to many.
There will be an opportunity for labor to participate in the merger process etc... but, in the end, no agreement will materialize and the courts will do it all. This will be the end of Duane Woerth and may be the end of ALPA as we know it.
The new airline will be a powerhouse.
Of course, I may be WAY off track, but these are my predictions.
