This is probably the top of the prayer rooms so far, literally. It was the first time for me to experience such prayer room inside an airplane where we can perform our prayer just the way we usually do on the ground.
To assist you finding the right praying direction, there's a small LCD screen on the wall indicating the plane route and current location. Hence you can determine the praying direction (qibla). There's also railing on the wall which I guess the prayers can hold onto in case there's sudden turbulence.
The prayer room is located in the rear side of the plane. Basically they removed three middle rows of economic class passenger seats to provide 3x2 meter space. Although the sign read that the area can fit 10 people, but practically it's only good for up to 5 persons praying together (1 imaam, 4 ma'mum).
During that journey I have seen more than 6 persons using the facility in separate timing, including myself and one of the female flight attendants. I've told that most Saudi Arabian aircraft have such prayer room onboard. It seems they don't mind loosing some seat capacity to gain more blessing :)
