Smart move on your part for getting the K class flexible ticket. I'll definitely heed to you advice for my next travel. You got a great fare from Cathay Pacific than me, though I suspect some of it probably has to do with  travel date. I booked the flight myself online, and found out that flying the month of December is a little higher than from mid January onwards. But I didn't pay outrageously high , about $250 more than you. But this ticket will cost me a lot more if I have to change the travel date due to HKG visa issue.

You said not to worry about visa in Hong Kong. Can you elaborate more on that? Because this is precisely my worry as I may not be allowed to board Cathay Pacific plane here in New York if I failed to produce Hong Kong transit visa.

I am wondering If you , or anyone you know had such experience prior?

P.S: Asia Miles membership is also another smart move.I also signed up for it the day I bought the ticket.

cheers!
