Yes, I had this problem and ended up tweeting @SouthwestAir.Just tried to reprice my flight to get a $50 credit and I got an error code. It just said cannot choose this flight at this time. Flight is at the end of April and not on max 8 Has anyone experienced this before?
I sent a DM regarding the problem, and they asked me to send screenshots of the page showing the available savings, as well as the page showing the error. Make sure to provide the confirmation number, as well, with everything sent in a Private Message - do not publicly post this info.
They were able to refare and redeposit the saved points to my RR account.
I find tweeting this type of issue, rather than calling in, works much more quickly and with a good resolution to reasonable concerns.
