only you can answer the question of, "is it worth it?"
To me, "credit" is some fabrication of a couple of companies out there. The facts remain that I am an individual who pays their bills ontime and is never late. I "churn" travel cards with the best of them. And I am refinancing my house with no problems from my credit card habits. ymmv. what do you need your "credit" for anyway?
To each their own. I would go for it, but since I have about 15 credit cards, I'm sort of maxed for a couple months now. And I focus mainly on international travel.
Question: Why not get the business card as well and get a companion pass? That's like $3300 worth of free travel! For $140 and a couple "hits" on your credit report...
So called Travel Hacking
