If I am "deciphering" these correctly it looks OK.

I called and asked AE a few days ago about my route and they agreed that it is valid because of the SQ published route.
But, my question is if I want to go via BKK (on TG) is that valid? Or is the airline that I use within the *A group restricted by the PR I quoted above? i.e. do I have to use SQ, which as we all know is next to impossible to get redemption seats on flights out of LAX/SFO.
