So who's booked to HKG this weekend? The obvious problem is what to do if UA voids these tickets (even if only temporarily) and you are in transit. It's obviously a long way home from HKG and I think everyone travelling during this uncertain situation needs to at least think of a back-up plan. I assume a one-way revenue ticket home would cost a fortune.
Using other frequent flyer miles for a one-way ticket back would seem to be the best back-up -- IF seats are available. What else could one do?
And, obviously, folks going in the next few days need to consider HKG hotel accomodations. CANCELLABLE hotel deals, of course.
EDIT: If you stay off the nonstops, I see that one-way fares from HKG back to the USA start at about $1000. In the scheme of things, that's not so bad! And think of how many ff miles you'll earn if you have to buy one.
