anyone know if its possible to change the last leg of a RT after the earlier flights have been flown with just a $20 fee or is it locked in at that point.
I.e. I want to book a one way with a stopover and therefore would like to use SQ miles but have no set plans to use the return flight so would like to be able to book it far out and just change it when i need it.
Would look like this
BGR-EWR (free stopover)
EWR-LAX
LAX-EWR (this flight would be flexible)
