747-300 = 743, 747-400 = 744. So, new nickname for the new Jumbo:
Budgie?
It did surprise me that the capacity expansion was so small, but already, BA seems to have warmed to the new 747, saying there were many unanswered questions about the 380.
As for other carriers: JAL, Cathay, ANZ (which has said it would order it if it were launched), CAL, SAA ?
Wonder if any M/E carriers would be interested? Saudia, perhaps, or one of the newer carriers, like QR/EY/EK?
