I think Air France could fly to Nagoya (Japan) as the economical situations in Asia gets better ?
Here is a speculation about the possible a/c :
The argument the Airbus A340-300 may offer to Air France is that it is a four-engine-powered aircraft, and CDG-NGO is quite a long route, so safety may be higher with two more engines.
The problem of the Boeing B777 is that it has only two engines and Asian people usually prefer to fly four-engined aircrafts, and they don't trust twin-engined as much as in USA or Western Europe where people have been used to flying on twin more than a decade ago. B777 in AF configuration has as many seats in high-yield cabins as in the B747-400, so that would be a problem to fill all those seats. A340 in comparison has a lower rate of seats high-yield per economy ones.
The Boeing B747-200 or B747-400 could also be a possibility, as it has a great number of seats in economy class. But it's huge aircraft to fill in also, and with all those seats in economy class, added to competitors capacities, that would easily flood the NGO market that isn't that strong (at least for now).
Between the -200 and -300 version, they's no problem thought AF hasn't A340-200s anymore.
I'm looking for all infomation concerning Europe-to-Nagoya routes and Nagoya airport ( firstname.lastname@example.org)
