Again, thanks for your fast response--trying to use SQ KFF, and having no luck at all :S. For reference, the flight I am investigating is SQ237 on 30 March, which is showing CS, but both SQ and a travel agent have told me no I class on that flight--shame really, I was hoping for that upgrade . Only telling you exact details because you might be able to figure out exactly what is going on--whether SQ have changed their feed on you or something.
