I see the 757s sticking around as pax like them and they really do have low costs. Additionally, they are doing the new premium service with the 757s, so they should be around for a while. The 747s are useful in many ways, namely in that they are paid for and many of the 777s are leased, so while they are (supposedly) selling some of the oldest 747s to Corsair, they are likely to keep a lot of them around.

A319 and A320 are newer, efficient, and popular with pax and pilots alike. 747s are useful for the Pacific but little else, so the numbers might normalize to whatever is right for that. 767-300 and 777 are good for Europe and transcon domestic. Newer 737s are fine for everything else on the domestic side that can't be served with an RJ, unless you need the capacity & low costs of a 757.
