Yes, I received one. I still like the idea of the threshold bonuses better, but....
The saving certificate I got as a Premier Exec (just got downgraded this year from 1K) was a saving of a certain number of miles (can't remember--varies by your rank) off a First Class award for two people. Since I would rarely redeem for a first class award, I am NOT impressed by it's value. If it was a savings off any award--that would be valuable.
