A look at any of the travel search engines will show MAS as having the cheapest airfares on almost any route they operat
I just now checked and no,they aren't cheaper than others. AMS-MNL chinese carriers have lowest prices between 550-650 eurs (end of nov-dec before 10.12 ) than malasian around 640 + eurs .
So what type of engines are you using? I will be interested in in prices europe -manila below 300 eurs
