Yeah, I saw that fare too. I have to give it a closer look and see what the SQ Euro-US options are on SQ. SQ A380 suites are not permitted on the F fare TTBOMK.
Depending on where you are traveling FC CirPacs on either OW or *A are about the same price ex-HKG.
Nice that FEZSQ is ex-US; but even though I am from the US I am currently positioned for and doing repetitive ex-HKG CirPacs right now. Thinking about having that come to an end at the end of this year.
I guess I need to go over to the *A forum and check it out.
