My first experience with Saudi Arabian Airlines and most likely my last. From the initial boarding a male flight attendant was rude and condescending to passengers. Once seated in assigned seat the aircraft was not full allowing myself and another passenger to share the four centre row seats. However before take off a flight attendant repositioned the passengers in front of us into our row stating the row was reserved. Although not pleased I thought that they had good reason perhaps a passenger who needed to lay down due to age or medical condition. However once inflight it became painfully obvious why the row had been vacated. The cabin crew actually arrived with blankets and pillows and throughout the entire flight from Dulles to Riyadh took turns sleeping. It was shocking that paying customers were placed in this position so the attendants could sleep! The food was good and adequate throughout the flight. The in flight entertainment initially appeared to be on par with other airlines however the movies ended 1.5 hr into the flight not to resume and no explanation as to why. I was very disappointed with the level of professionalism extended by the cabin crew in particular the male attendants. I will go out of my way to fly with another airline in the future even at an increased expense if it means avoiding this kind of experience again.
