Don't know why so many people are so confused about what the venture points get you. It's really quite easy. All you do is use your Venture card to purchase regular travel, flights, hotels, taxi, etc. Then, you login to the rewards website and select purchases for reimbursement.
For example, if you buy a plane ticket for $200 (this is a normal revenue ticket BTW) using your venture card, you go to the venture website, and redeem a $200 credit on your statement for 20,000 points. Done. It's really that simple.
Only thing you lose is the $200 spend on another card (or any multiplying factor you have) on that other card.
