Top Gun : You're right, I should have been more precise. I've only heard about Saudis in Riyadh. I don't know about Jeddah !
Metro : Yes, it says for non Saudi only, but this is the old bulletin. Saudi Capt / FO in Riyadh have been offered the choice when bidding for next year Vacations. Either 20/10 or 30 days vacations.
For the Riyadh base joiners, and until the end of 2017, the lines will be as followed : 20/10 with 5 consecutive days off and 5 reserve days; or on a 25/5 basis. This is because the new joiners had their vacations in 2017, while the ones who joined Ruh base in March were not untitled for it.
