The 744 will be phased out by April 2016 and all IP's have been given the option to bid for the 787. Everybody else have 2 options: 1. B748 Cargo 2. B777.
I don't agree about bringing all operation in-house, this sounds like one of a multitude of rumours. There are too many vested interests in the wet lease operation for this to be a significant option. In addition to that AAI provide reliable substitute aircraft which are currently required on a daily basis. If it is a plan then that is all it will ever be.
