Welcome to FT,
SQ-1B! Is that your reserved seat?

If you had been
SQ-3A or
SQ-3F then... (I'm not gonna say anymore

)
Btw, where do you get the information on the fee waiver? I don't see it in the webpage. I'm wondering whether AMEX will offer a free switch to us PPS who have the Amex Krisflyer card already...
