Qatar Airways will restart daily flights from Doha to Riyadh on November 13, and it will resume service to Dammam on November 14.
From November 21 the airline will increase frequencies to two daily flights each on the Riyadh and Dammam routes, rising to three daily flights each from November 28.
Flights to Abha and Taif remain temporarily suspended. The company had halted its Riyadh and Dammam routes on October 12.
Operational reasons were cited for the suspension, but Qatar Airways did not explicitly link the cancellations to the attack on Riyadh's airport on October 8, which killed three Saudi citizens.
