I have a First Class Star Alliance Circle Pacific booked but not yet ticketed. According to my TA, my SIN-SYD booking on SQ221 was changed from A to R class by SQ; but when she checked with SQ, she was told Suite Class was not available to Circle Pac or RTW ticket holders, even for a surcharge.
So my confirmed booking on SQ221 has now sadly become a waitlist on SQ231...
