For clarifications:
The SWA agent asked me for the credit card used for the tix I had wanted to cancel.
When I told her it was purchased with a confirmation # from a previously cancelled tix, she then informed me that she couldn't give out confirmation # for security reasons.
She didn't ask me for the credit card of the original tix. I had my card with me. If she had asked, I would have given it to her.
After I had explained to her my situation, my being stuck hundreds of miles away from home, trying to cancel a tix, trying to get home, one would have thought a reservation agent would have been more helpful.
I can understand for security reasons things can not be done over the phone, but she didn't even give me any options or suggestions on how to cancel the tix and apply the credits towards a flight home. She just repeated again that for security reasons confirmation #'s can not be given out.
I didn't know that unpaid reservations exist!!!
Wow, I guess I am learning a lot when things go wrong...
