Just got off the phone with a Chase supervisor. After 10 minutes on hold, I was told that I must spend $5,000 before I can receive the $99 companion certificate.

Edited to add:

I see the new limitation in the terms and conditions. The old terms from last year said: "$99 Companion Certificate on your six-month anniversary as a cardmember...."

Does anyone know when the conditions for the $99 companion certificate were changed?
