I'd like some clarification on "no-cancellation fees" for international flight. United says "You also won’t pay change fees for international travel originating in the U.S."
For a trip to Portugal, does that cover the flight out and the return (We're planning for DEN-LIS, OPO-DEN?
If part of the flight is on Lufthansa or TAP, will those cancellation fees be waived too?
And finally - how long will I have to use the credit?
Thank you (So much information here!)
