Chennai (MAA) ⇄ Kolkata (CCU)

2 occurrences on flights between Chennai International Airport and Netaji Subhash Chandra Bose International Airport, as the departure and destination were reported for the first aircraft involved.

Reported airports are matched to an airport only when the match is unambiguous, so flights whose airports were recorded loosely are not counted here. Records hidden on the map by default (minor, with little written about them) are included.
