The FA's in First when I got an op-up from J certainly knew what had happened... (ONE paid F and
me.. that was the pax load in F..

) but if the service/treatment I received was somehow diminished as a result then all I can say is the "real" F service must be amazing indeed....
(I don't think for a moment that those 2 wonderful FA's cared in the slightest- in fact I think they took GREAT pride in showing off the service)
To the OP: Enjoy your trip!!! ^
