Actually, the sign-up page says you only have to be a family member of a Vet. You do not actually have to have been a vet yourself. If you read the fine print it costs about $60 per year. Unlike the old deal with Chase, it appears that the discount does not go away after 12 months and you can charge your CO purchases to the credit card of your choice. I just tried to sign up but got an error message. Do other folks recommend the program, and does it work like Chase with you putting ONEPASS in when you book?
Also, are some fares not eligible for the discount. They don't say so.
