I'm waitlisted for an award J ticket for CX846 (Jul 20) and CX831 (Aug 2). I've also got a Y ticket held but ticketing is tomorrow and I think if I let it expire, the price will jump even more. What is the collective wisdom here?

Dunno how likely TPAC flights are over the summer (esp to NYC) and while my outbound is flexible, I have to be on CX831 return. Maybe just buy the economy tickets and bit the 1800HKD cancellation cost if I get off the waitlist? (Also, as an aside, the rebooking/cancellation costs have gone through the roof - it used to be 600HKD a pop and it runs from 900HKD (lower cost regional) to 1800HKD (TPAC)...)
