For Delta:
The official number is 300 (that's what has been funded). That being said... they will most likely receive funding for a total of 600 pilots for 2014. That announcement should be forth coming soon.
Now, I also had a conversation with someone from Network who said they would like to hire 1000 pilots in 2014. We shall see who wins out. I will put my money on 600 plus for 2014. It's real hard to pin Delta down on what, how much or where flying will be taking place.
