Air Astana is to launch a new route from Heathrow to Astana, the capital city of Kazakhstan.
The Kazakh airline will add the new weekly service from 31 October alongside its existing twice-weekly Heathrow-Almaty route.
The Heathrow-Astana route will operate on Tuesday with a 17:15 departure from London for a 05:30 arrival the next day at Astana.
Astana-Heathrow flights will run on Thursdays with a 15:15 departure for a 16:05 arrival in London.
As part of the changes, Air Astana’s current Heathrow-Almaty service will switch from Tuesday to Thursday. The other Almaty flight departs Heathrow on Saturday.
