kmp - clearly JAL thinks a market exists -- they are using BOS to NRT as the launch run for the B787 in the US
I never said anything specifically about Tokyo and the 787. On the contrary, I think Tokyo will do very well for JAL and I wouldn't be surprised to see it running as a 777 in a few years. My comment was in reference to this:
If Massport had the quality management jet blue has, there would be 747's flying to numerous Asian cities. maybe it will happen anyways...
Ultimately I suspect like most members of the traveling public, the writer wouldn't know a 747 from a 7 & 7, much less a 747 from a 787.
The only cities with the sort of demand to pull that off on their own are New York, Los Angeles and San Francisco plus Chicago, Atlanta and Dallas when you consider their feed as hubs.
