Flopster,
To be fair the 737NG has only been offered for HALF the time that the A320 has been offered. If you included 300/400/500s sold during the same time period that the A320 was offered, boeing wins. If you include on A320 sold since the NG was offered boeing wins again...
Same thing for the 330/340 vs 777. 330 and 340 go back to well before the 777. 330 was designed to beat the 767 which it did. ofcourse the 767 was designed to beat the 310/300-600 which it most certainly did. 777 has pretty effectively buried the 330/340 since it came out... however the 777 is a little large, hence the need for something in the 7e7 size...
747focal. The 747 has been the largest profit center for boeing for a VERY long time. The developement costs have been fully amortized. Much of the expense of building an aircraft (cockpit and engines) aren't that much different than a 737 (cockpit the same, but a few more engines) yet you get a HUGE increase in sticker price due to the greater "value" of the work the747 can do. But the 737 are barely a break even aircraft. The real money for boeing has always been in the larger aircraft...
Without the 747s purchased for range the production run of the 747 would have been similar to the A300 A310 production run which airbus even in their most optomistic moments has never claimed was a profitable program.
Cheers
