I’ve updated the cards and links in the Southwest Companion Pass Engine. It used to be that there were 4 cards – Plus (69 fee, not waived first year) and Premier (99, same) offered both as personal and business cards. Not so today. Personal Plus and Premier are both available, but for business, only the Premier. You only really need two to get the card – and I know multiple people who have three cards.
In any case, the way the engine is coded, it will show both personal cards. If you’d prefer to have one as business, then the link for the Premier Business card is here.
This is pretty much the best travel deal going if you are looking for domestic travel for two (with a few international locations off the southern states.)
