I will go with Atlas, but CX
744F I believe has just been delivered, so will come off the unfilled anyway. I was trying to think of a carrier that may have swapped some 777's for the 747, but only AF
really stood out, but they probably require that second ERF
I too cannot see PR
taking the four 744's, maybe Boeing could get them to change to 787's.
Sorry to say it, but the 747 and 767 may be halting in a similar timeframe! Two of my favorites.
