The first link is broken.

Anyone knows the problem still persists?

I need to either cancel 2 refundable tickets or to rebook them to something else. Travel date is in August but we would be out of the country from Mid Jul and not come back until Mid Aug past the travel date.
So really need to do this before leaving.

I prefer to do the cancellation but after reading this thread I am afraid the refund would go to a black hole.
