The subsidiary of the AirAsia Group announced it would do so from March 24.
An AirAsia executive in India confirmed on Tuesday that the airline had announced withdrawal of its flights between New Delhi and Bangkok, owing to high operating costs that include high airport and fuel charges.
Thai AirAsia operates a daily flight between the Indian and Thai capitals, besides a weekly flight between Kolkata and Bangkok.
The Kolkata flight will continue to operate, the executive added.
Withdrawal of the service between Delhi and Bangkok will begin with a cutback to four flights a week on February 14, from what is seven now.
On March 24, it would come to a complete suspension.
