This was actually announced by Khun Chai some time last year already, so it is not exactly the news that site is trying to make it. I think we actually discussed it on here at the time, if my memory serves me right.
I personally am not a fan of the "Business Suites" concept, to be perfectly honest - so it is quite sad to see this go. I do however, recognise that it makes little sense to keey a whole F product going for the sake of three planes.
