I am not sure what other airlines offer, but I am fully satisfied with United Airlines Mileage Plus Program. I do about 100K miles a year. Having put 100K almost every single year, this is what I get:

1. Platinum Status
2. 6 Domestic Upgrade Certficates
3. 6 Global Upgrade Certificates
4. Free drink coupons

I am not an efficient user of miles. I also forget to record a lot of miles when I use partner airlines like Thai, Shenzhen or Air China.

What Platinum status got me:

Automatic upgrades domestic and international about 60% of the time. Economy Plus seats. Priority boarding. Lounge use when traveling international. Last year I did not use any of my upgrade certificates. I did not realize they expire. So, I could have got more upgrades if I had used these. I only recently learned that they expire.

When there are delays, I call the platinum line right away, and they get me flights and always put me in front of the line for any waitlist.

Maybe others can tell you more. But I like my UA status and mileage program.
