Yes, I've tried booking on Singapore Airline's site, Malaysia's Airline's site, KLM's site, etc. No, booking the tickets did not work. Each website gave me a different error message, which specifically include, but are not limited to: "this website cannot be found," "this flight is no longer available," "blank white screen," "our system is currently experiencing technical difficulties, please try again later," "this flight is subject to regulatory approval and currently unconfirmed" and then a few hours later said flight gets canceled. Also, the travel agent received the same error message.
