Issues using partial flown ticket credits - limitations due to flown segment
A friend has SFO-TPE roundtrip ticket and had already flown the outbound. He changed the return flight two months ago and got a $360 FFC. Now he needs to change the flight again and United is quoting an extra $600, due to the new flight date is beyond the maximum stay allowed on the ticket. A new OW ticket costs $750.
Is it possible to use the existing $360 FFC to pay the $600 fare difference? There doesn’t seem to be such an option on the website.
The United app is showing 480 PQP for the current return flight. Is that the residue value? If that’s the case, would it make more sense to just cancel the return flight, and use the new FFC ($480) and the existing FFC ($360) to pay for a OW flight?
