I just tried mine and got the following offer. Too bad it appears to be expired. The odd part is that it shows another section of expired offers - this one not included. My card has been open about 1.5 years.

You will receive a $50 flight discount after you spend $1,000 or more in purchases from the day you activate through December 31, 2016.*

We appreciate your business and hope you enjoy all of the benefits your card has to offer.
