1. Cancel the original flight and get an FFC.

3. Start a new, clean booking of the desired flight and then use the two FFCs as a form of payment
What happens if it's a 2pax reservation that you need to ultimately book? Can you make the TB res for one person, cancel after 24 hour, then use the FFC on 2 pax?
