You are revealing your lack of knowledge here. SQ sent an email to its frequent flyers in July 2011 apologising for their new website. Their website is a disgrace. I can't believe they haven't reverted back to the old website.
How is the website a disgrace? It does what it is supposed to do.
I am not a member of Singapore Airlines FF program but am a member of United Airlines who is a Star Partner that Singapore Airlines is on so in my case I would actually be booking through United's website as a codeshare partner.
But thats besides the point. I went to the Singapore Airlines website and it looked fine to me.
