Have some travel coming up on Alaska and decided to attempt to status match from UA 1P to AS MVP Gold.
I signed up for Mileage Plan then sent an email to the address that I found in other posts on this thread with a copy of my new UA MP card and statement that came not so long ago and a short note. I didn't get a response though MVP Gold status is now reflected when I log in (whole process <24hours). Looking forward to giving AS a try in the coming months. ^^
