I have travel on AC scheduled, originating from ORD, late next week with a connection through PEK. I can't get through on the phone to cancel. When I go to the website, it wants to take the $300 fee and other "unrefundable" fees totaling $700+. I can't rebook right now because we don't know when it will be okay to travel to China, nor when my partners' offices and factories will be open. Should I wait it out a few more days to see if the policy becomes more flexible? Should I try calling middle of the night when call volume is lower? I'd sure like to retain the full value of the ticket for a future booking.

PS: I had two separate bookings. UA cancelled the domestic US portion with no issue at all. XXX-ORD-XXX was cancelled with no fees applied. Done in three minutes. Thanks UA!
