Qatar Airways has increased the number of flights on its Doha to Jeddah and Riyadh to Dammam routes.
An additional five flights a week will be added to current daily flights on the Dammam route, with the changes having come into effect on February 22nd.
The Riyadh service will benefit from two extra weekly flights, with five flights now operating on the route each week.
In addition, Qatar Airways will launch a new long-haul flight to Houston, Texas, on March 30th.
Akbar Al Baker, Qatar Airways’ chief executive, said he was "delighted" to see an increase in flight capacity.
"Houston is a very strategic route for Qatar Airways, as it opens up increased bilateral business opportunities for the energy sectors across the Middle East and the oil-producing southern states of America," he said.
Leisure travellers flying to and from Saudi Arabia will now benefit from greater choice when accessing Qatar’s flights network, which covers destinations in North America, the Middle East, Africa, South Asia and the far east.
The airline announced earlier this month that it had added a Boeing 777-200 to its fleet of aircraft at Doha International Airport.
