The airline, the budget arm of the national carrier Air India, will provide the service four times a week -- Mondays, Tuesdays, Thursdays and Saturdays.
On the Dhaka-Delhi sector, the flight will be on Tuesdays, Wednesdays, Fridays and Sundays.
The carrier has a code share with Air India on this route. Besides, it plans to provide code share connections on Air India flights from the UK and the US to Dhaka and vice versa via Delhi, according to a press release.
Air India Express CEO K Shyam Sundar said the airline will offer competitive and affordable fares on both sectors.
