I know you lose 25% of your miles for cancelling but is there a time limit before the flight? i.e. can I cancel the day before and still only lose 25%?
If for any reason a flight reward is not taken up, inside 7 days of departure, no miles will be refunded and no fee will be charged. No changes can be made within 14 days of travel.
Yes, indeed you do lose 100% of your miles within the 7 day deadline but what the nice lady at FC did for me was cancel my trip but leave the ticket open for 12 months from the day of booking so, I still have my UC return to use at a later date.
