I don't have elite status with Continental OR United, but merged my accounts last year. Logged in all the time to see if I got the 60k offer - nothing.
Logged in tonight and the offer was right there on the home page. My elite status is still zilch, but I got the 60k offer.
Maybe it's open to everyone now? I'm thinking so!
This was the URL for the offer page:
