I haven't seen this on here so here it is...http://phx.corporate-ir.net/phoenix.zhtml?c=92562&p=irol-newsArticle&ID=1461656&highlight= I don't think 21,000 SPG points for 17.5 RR credits is that great of value, but this is nice if you need to top off your account
20K SPG=16.5 SW.120K SPG=99 SW.121K SPG-100 SW=6 RT's+Companion pass.
The best deal is to open a new southwest account and get the free 6 or 8 credits.
