It means the carrier will operate five times a week to and from Heathrow from mid-November to early March next year. Air Mauritius had been scheduled to operate a fifth "Christmas peak" frequency from 13 December to 10 January.
However, this will now operate from 14 November to 7 March 2023, sales manager UK and Ireland Allan Owen confirmed on Tuesday (27 September).
The additional flights will depart Mauritius on Mondays, with returns the following day. Air Mauritius will operate the route using an Airbus A350 aircraft.
