Although it’s a morning flight from Washington Dulles International Airport, it’s really a short time trip for Kolkata passengers. One can reach Kolkata at 4:40 PM within 21 hours. Only one issue I am concerned that the Air India staffs at the Kolkata airport counter should be trained to help the passengers and behave appropriately. Check-in at the counter with luggage was very confusing and the lady was very rude. Overall, the trip was fine.
