Last May 23 2011, we book flights for Dec 2011. As time went by, the fares got lower and we got credit. In Jan 2012, I booked flights for May 15 2012 using the SW credits and CC. Again flights have gone down. But it would appeared that the credit I am now getting will expire on May 23 2012. I thought the old credits would have been used up and I would have new credit that would be valid until Jan 2013.
I don’t see a page of rules listing what’s what with using credit. Can anyone see one? I’d rather read something before calling them up.
