can someone update the FAQ - NO UPGRADE IF YOU HAVE INFANT... sorta obvious but still....
I (silver, on N class) was travelling with infant + child + wife 4 ppl on same booking to Cebu recently. Flight was full. At checkin the agent offered me only an upgrade to J whilst others sit in Y. I refused and sat together with family in Y. In past I have been upgraded with my Green Wife only (yes even as Silver).
Child also may have dampen my luck but rule of thumb is even if you are travelling with infant, yes you might get a shot for upgrade at checkin but unlike those automatically done prior to arrival, infant/child will defuse your luck.
however anacdotal evidence of my colleuge (DM) is he and his entire family (including maid) was upgraded on flight to Tokyo, so being DM will always help of course.
