since when are Continental and Delta not USA airlines?
yea but only 2 US airlines have it. Why are there no other carriers that have it and why only 2 airlines in the whole world.
1 reason is that all of the other companies who ordered the 764 cancelled/shifted their orders after the 764ERX program was killed.
Other reasons are the 764ER's range-limiting wing (specilized to fit into existing 767-capable gates) as well as its inability to carry LD3s in tandem, as the A330 can.
the 764 is a great plane to fly on, and it would probably do well in other international airlines fleets
...apparently, those airlines think otherwise.
