Seems like a good showing for Emirates. I wonder how Turkish will impact them.
I'm not sure how much since Istanbul hub can serve Western/Eastern Europe. The question may be how do both airlines affect the European incumbents. Prices aren't too cheap for summer travel right now so the true war of attrition may start in October.
I'm wondering if Massport will "classify" the Istanbul flight as Middle East or Europe. You can make a case for either/or. Geographically - Europe (airport is in Europe) Culturally - Leaning towards Middle East. Turkish has also been serving the route so far with different aircraft (A343 and A333 have both been used) so it may be hard to get the numbers until the DOT releases them a few months down the line.
Also wonder how Hainan will impact JAL. If JAL has a base that continues to Beijing, it could be some lost numbers.
Shouldn't have any impact. The Boston-Tokyo flight does not connect well to China on the return home and Hainan is gearing this flight to served Beijing's (and the rest of China's) middle class with tourist packages to Boston and New England in general.
