70K for J for JNB to HKG (No F on the route) HKG-JFK in F
62.5K for J all the way through.
Obviously worth the extra 7.5K for the F segment
I'm not sure how much the chase car and the backup reservations will cost

Excellent! Thanks for the quick response. Assuming F only opens a day or two prior to departure, the fee is $125 to change? Also, if you're already on your layover when F opens, shall I assume you can NOT upgrade since you already began the award (ie already flew JNBHKG in my example)?
