Air India continues to add new long haul flights in its network. As promised last year, it is going to start non-stop service between capitals of India and USA i.e. New Delhi and Washington DC. Air India officials in October 2016 had mentioned that they wanted to add at least two more US destinations to their network, however due to shortage of planes, they had to hold back. They may add another destination as promised last year, I believe that could be Los Angeles.
The service will be thrice a week to start with, using a Boeing 777 for this flight. This flight adds on to the 4 direct flights that Air India already has to the USA from New Delhi (to Chicago, New York and San Francisco) and Bombay (to Newark).
