Do not expect Delta to pull the MD-11 fleet. They will add the 767-400ER next year, if the ALPA will fly the planes for a reasonable price. Right now, Delta is offering $195,000 per year for the planes. The ALPA has not made its 1st offer. We'll see what happens.
As for the 777, I think that it will eventually be a part of the fleet, but not until the next contract is signed. So the MD-11 will probably stay. They continue to spend a great deal of money on the fleet. However, it remains the most unreliable plane that they have had in recent decades.
Delta's future viability is heavily dependent on labor relations with the ALPA. Delta's pilots, as a whole, are widely disliked by the rest of the employee body. As an Atlanta resident, I have many friends who work for the airline and who often chastise the ALPA.
I think we will learn of Delta's future over the next year as Contract 2000 negotiations are started. Don't hold your breath. Over the last 12 months, the ALPA has killed a pact with United and killed the B777 fleet plans. Over the last decade, the pilots have caused numerous other problems for the company. If the union had agreed to a pay cut with the Delta 7.5 program, Delta would not have had to lay people off. But no, while all of the other employees of the company took a cut, the pilots simply did not receive a raise.
It is a shame that such a great company with such a strong financial situation is being held captive by the one union that has any real strength in the company. The pilots want a seat on the Board of Directors. However, they do not want to pay for it. So I think that all of these problems would probably be solved if the pilots started buying huge chunks of stock, and then elect one of themselves to the board.
