I have an ANA award on ANA metal and already have flown the outgoing flight, it is a round trip from JFK to Tokyo.
For the remaining return flight am I able to:
1) Change to a different airport for the 3K points fee, for example change from JFK to ORD?
2) Change the return to a United flight for the 3K points fee (For example NRT to EWR)?
Any help would be greatly appreciated!
