Just 4 days ago, I cancelled a ticket. It briefly existed in the TRAVEL CREDIT section as a FLIGHT CREDIT and a few hours later was reclassified as a TRIP CREDIT. This was great, because the TC is usable for a year from issuance. As you probably know, a FC was valid for travel only up until one year from the cancelled tix' issue date.

As an aside, some months ago, an EXP agent told me they were moving to TC exclusively. So much time elapsed, I had decided that was not going to happen. It was a pleasant surprise.
