Just pulled the plug on CGK-HKG-DFW-DEN for 11 NOV. Both F and C have been zeroed out for a few weeks. Agent would only say chances don't look stellar to clear. Don't want to risk upgrade not clearing. Paid change fee and far difference (less than 300 USD) to reroute CGK-NRT-LAX-DEN. SWU for NRT-LAX-DEN cleared at changing booking.
