Yup...just start Googling. WN is on of the few that does not status match but most of the other big players do in one form or another with various restrictions. Most are are 90 day match with a minimum points/spend challenge in that 90 days to maintain status for a full year or term.
I got a status match from WN A+/CP to Virgin America Gold a while back and used the heck outta that for non stop routes that WN didn't fly. I love Southwest but having first class upgrade being available for change were pretty sweet!...sad to see them go.
