QR will fly DOH-SFO and DOH-SEA four times a week, both services using A350-900s.
Alaska and QR have also announced a mileage plan partnership effective 15 Dec, coinciding with the SFO service. Of course they were going to be partners automatically once AS joins Oneworld (31 March 2021) but this will give them a head start. AS currently partners with EK, but whether that survives AS' Oneworld entrance remains to be seen.
