You are now enrolled in the SkyMiles Elite Match Challenge. Your temporary Medallion status will be effective on November 10, 2016. Please look for the terms of your 90 day offer to be sent to the e-mail address in your SkyMiles account. If you have any questions, please reply to this e-mail only. Southwest is matched up to our Gold Medallion status only - we do not match Companion Pass.
We appreciate your interest in our Medallion program, and look forward to proving ourselves as your airline of choice.
