Other Middle East and Africa Frequent Flyer Programs - Saudi Airlines from SIN or KL

Hi there,
Anyone travelled saudi airlines from singapore or KL?

How are the seats compared to other airlines (Emirates, Singapore Airlines).

Also how easy is it to purchase a ticket via their website online?

Regards

I'm not sure what metal they use to the far east, but their website has improved out of all recognition recently. It's pretty easy to book through it.
