While the airline is focusing on the challenges of increasing business from India's eastern city like Kolkata by wooing more leisure flyers, it is set to launch four flights a week from Ahmedabad this year.

"In North India we have three flights a day from Delhi. We plan to add Ahmedabad in 2020 with four flights a week," V Ravindran, Regional Manager, India and Bangladesh, SriLankan Airlines told IBNS.

Calicut in South India is another connection on the cards, he said.

According to Ravindran, the Kolkata market has grown by five percent overall in the last year as its catchment areas are different and challenging.

"The main flyers are labour traffic and leisure. There are challenges but it has potential too and leisure traffic is only rising," he said.

Shiran Kretser Silva, Area Manager, Kolkata, SriLankan Airlines, said there are 3 flights a week from Kolkata now, while subject to availability of aircraft they would increase it to four.

He said promoting dual destination is important for the airline.

"So we are promoting Colombo with Sydney. Anyone flying to Australia by SriLankan Airlines can stop over in Colombo and enjoy a few days' holiday as well," said Silva.

"Entire India is getting to know us now and taking us well," he said.

According to the officials, while 95 percent cabin factor (occupancy) are in Economy Class, it is 30 to 35 percent in the Business Class.
