Don't know if someone here understands how *A upgrade work - I'm having the fololowing issue and run-around with TK/SQ.
I'm trying to use my TK miles to upgrade a Y fare to Business on SQ800 on 25th Oct.
TK chart tells me I need 35,000miles.
I call SQ and they say they are out of saver "I" fares but still have "D" standard redemption fare slots available.
What does TK book into - using the TK/*A redemption site it gives me the following error: "Inventory not Available.(SQ /511)"
Am I simply out of luck, and I need to be looking for "I" class availability?
