The prayer room in the back says it all. This is no generic flight experience.
Turn on the in-flight entertainment and everything is edited and sanitized. A local cartoon featured a character with a metal face guard like I saw on one elderly passenger.
The seat is an economy seat, no more or less. There are various rows with extra leg room or only two seats so it pays to study the seat map. I got a row of two in the back with three seats in front so I could angle my legs out with the third seat acting as a shield.
There is a modest amenity kit.
Food is fine and includes both local and more generic options, with a proper menu.
The snack bar is stocked with little snacks and juices, would have been better if I had remembered to take a picture before clean-up.
The flight crews are primarily Filipino women with a few men overseeing things. Indifferent but not US-style surly.
On my four Saudia flights, two long-haul, two short-haul, I do not think I have ever seen passengers, in both classes, constantly popping and up and down as much as this.
UPGRD Matthew has the definitive review, I am just am amateur.
Saudia is often reasonably priced for revenue tickets and a good option for long-suffering Delta flyers looking for awards. See also my take on Saudia Business Class.
