Qatar Airways will introduce a fourth daily flight between Bangkok and Doha to meet growing demand, particularly from key feeder markets across Europe, the Middle East, Africa and the Americas.
The additional service, starting on Feb 20, raises the airline's frequency between the cities to 28 a week, marking a significant rise in capacity on one of its busiest routes from its Doha hub.
Qatar Airways, one of the world's fastest-growing airlines, will continue to deploy Boeing 777s, the long-haul wide-body jets, on the route.
Chief executive Akbar al-Baker said the additional flight is possible because more long-haul aircraft are joining the fleet.
"Our strategy has always been to serve popular routes with multi-frequency flights, and Bangkok is an example," he said.
The airline will embark on new routes next year including Gassim, Saudi Arabia (Jan 7); Najaf, Iraq (Jan 23); Phnom Penh (Feb 20); Chengdu, China (March 19); Chicago, Illinois (April 10); and Salalah, Oman (May 22).
The airline flies 116 aircraft to 122 cities.
