well, since US is quarantining even US citizens upon arrivalb for the first time in 50 years (if they have been in China), I expect alot more leniency on AC cancellations.
I had to cancel a weeklong Easter trip to Japan & Shanghai with a friend because he works for the US Gov't (FAA) and they just banned Asia travel for employees-even on personal time. They are not able to take a risk of essential employees being quarantined and unavailable to report to work at the end of the vacation.
