If you didn't use ticketless funds for the $5.60 fee and if you care about preserving refundability of that $5.60 you would need to cancel and rebook rather than just change the reservation.
Just to be sure I understand.
If I cancel, I will be get my $5.60 back on my credit card. Then I will rebook at the lower points and pay the $5.60 again and get a new confirm number.
But if I change the reservation and something comes up and I don't go on this flight, then the $5.60 will turn into funds that must be used within a year of original purchase date.
Correct?
