Qatar Airways will increase services on its Doha to Moscow route to 14 weekly from September.
At the same time, the carrier will replace the mixed fleet of A321s and A320s that currently ply the route with a B787 Dreamliner and a newly-upgraded A320.
The twice daily schedule will, from September 1, see outbound service QR231 depart Doha and 0725 and land in Moscow at 1315 local time. Return flight QR232 will take-off from Moscow at 1445 and arrive in Doha at 1830. Both these services will be operated by a B787.
The A320 will be deployed on QR229, which departs Doha at 1245 and arrives in Moscow at 1855, and on return service QR230, which leaves Moscow at 1955 and lands in Doha at 0005.
Akbar Al Baker, Qatar Airways CEO, said: "We established our Moscow route just over ten years ago, and since then we have watched it grow steadily.
"I'm very pleased that we are able to meet our customers demand by increasing not only the frequency of flights per week, but also introducing one of the most state-of-the-art aircraft in the world to the route."
Qatar Airways has also confirmed it will start operating services to Al Hofuf in Saudi Arabia, its seventh destination in the country. The new service will fly to Al Hofuf from Doha four-times a week, starting on May 15.
And the airline will deploy a two-class B787 between Doha and Edinburgh from May 28, intially five-times weekly (see news, March 25).
