This can't possibly be just me - because I've been seeing this error for many months, and on different computers, and on different network connections. Every other two or three times I try booking a trip (with points), at the final submit screen, I get this error. I go back and re-enter the notification type, credit card, etc. and submit again and still get it. However this last time, I complained to southwest, then went back and it worked (maybe it's a session thing). Please tell me it's not just me...
