Anyone have any suggestions for the "Sorry, we have been unable to complete your transaction at this time." message?
I'm getting this when trying to book intra-Japan JL flights (with tons of availability).
I've tried different credit cards, phone numbers & address formats, with/without EC membership number, etc.
The only thing "different" I can think of is that I transferred UR points into my account this morning, but they instantly showed up. And, I've done this transfer/immediate redemption before without issue.
