The Best Award Redemption Available
I'm a big fan of the Alaska Airlines credit card. For a $75 fee upon sign-up, you get a companion pass and bonus miles. Bank of America also has less stringent application rules, so it's possible for you to sign-up for and cancel an Alaska Airlines card each year (or more) to bank more miles. But for some Alaska Award redemptions, you don't even need to bother with that.
For instance, Mile Value has found a sweet spot redemption where you can book a trip to Hawaii from the mainland for 17.5k miles. Alaska also allows a free stopover on Award Redemptions. So, you can check out two islands or stop at a west coast location on your way!
