Can't you just cancel and only forfeit $5.6?
Cancel and rebook. What are the cancellation fees. And you may lose the return that way, unless each leg booked separately.
That's what I once thought.
But for international flights, wouldn't you forfeit the taxes, which in this case, were almost $55 (same as the change fee)?
I have the return booked separately, so not worried about that.
But I do worry about cancelling and then having available space disappear while on the phone with the rep. Much rather have them make the change without cancelling. Call me paranoid.
