One flight credit that I had forgotten about popped up at the bottom of 'Manage my Booking' a few weeks ago. Also two travel passes that had been used
. One then disappeared, but one remains.
I've been hit with a 'Change Fee' of $99 as it was a Red-e-Deal fare originally (I checked this out thoroughly - its legit, but really annoying, as you have to spend at least the value of the credit, but then start $99 behind
)
