According to the The Telegraph of India , Indian Airlines is withdrawing from Kolkata (Calcutta - CCU) to Dhaka (DAC) route. They have instead went in an agreement with GMG Airlines to serve the CCU-DAC and CCU-Chittagong markets whereby GMG flies Indian Airlines passengers on those routes. The move is said to be temporary, however, my gut feeling is that they won't restart the route anytime soon. There was a time when IC used to fly daily to Dhaka, and even 2 flights on certain days, but over the past decade, they have been reducing frequencies gradually. BG seemed to enjoy a near monopoly on the route, but AI and GMG changed that. This is great news for GMG as they can tap into IC's vast network across India.
AI's 3x weekly flights between CCU and DAC remains unaffected.
