It is always a pleasure to interact with the ANA ground staff at the reservations office in India specially in the capital. They are courteous, helpful and flexible. They are always ready to offer alternative fares and alternative flights to make your travel experience with them as pleasant as possible. What I like the most about them is that they always give you sufficient time to re-confirm your booking with them before payment by putting the booking on hold for a few days because they are confident that their customers would always return to them and the new customers would choose them.
NH flights as well as their code share flights with United Airlines to U.S.A are quite convenient and affordable and more so if you are flexible with your dates. As it is they offer the best fares to Japan and a host of other amenities and discounts on your arrival there to enjoy their country to the fullest.
