Can you book ke using af miles as 1 award?
did you mean AS miles? if so, based on above advice, it seems yes.
Can you stopover in hkg? Even on a one way?
If he wrote AF, he probably means AF...
CX bringing the a350 on EWR to HKG from late October 2017. Can fly a great business class product all the way to TLV.
While it's a nicer plane to fly on than the 777, it's going to be a reduction in the number of J seats and no F cabin so much less award availability in premium cabins.
