I've been watching the Southwest website for the extension of a bonus credit for booking online, and we may be out of luck.
Until yesterday the date was still April 1, 2005. Today there is no mention of the promotion, at least as far as I can see. That means 8 round trips to get a RR ticket.
Hopefully I am wrong. This wasn't as good as 2X credit, but better than nothing. Too bad....
