Because I was so tired of planning my trip around award seat availability, and because they gave me a sweet signing bonus (110,000 miles) I switched most of my spending to CapOne Venture card. I love the flexibility of this program:
Double miles for every dollar spent. 100 miles for each dollar spent on travel, which is subsequently reimbursed in cash. Example: I pay $1000 fare to Hawaii on my CapOne card. I apply for reimbursement of the entire flight at the cost of 100,000 CapOne miles, which equates to $50,000 in everyday spending. Since I paid cash, I get to pocket the frequent flyer miles after I fly. Since I haven't been able to fly to Hawaii for fewer than 70,000 Delta miles in years, which is $70,000 in Delta AMEX spending, I come out ahead on all fronts. And since I'm free to pick my own itinerary, I don't have to do creative things like flying into another island on a Wednesday.
So, except for the fact that I still accumulate miles for flights flown, I'm done with the award ticket game. In the future, I'll just book the best itinerary I can find, for the best price, and then get reimbursed in cash.
