I applied for a UA Visa. I guess I forgot to put in my UA number because they opened up a new MP account for me. In the welcome package is a coupon that says I will get double miles on my next flight (within 90 days). All I have to do is register here.

When I go to that page there is no mention of it only being for a new account--so I guess it will accept all MP numbers. I put my existing one in. We'll see what happens. If you use it, report back and let us know!
