This bonus is worth $1,260 because of the value of the Alaska miles at 1.8 cents each. If you redeem these miles for flights on one of Alaska's partner airlines, you could potentially get more value out of it. A business class award from the U.S. mainland to Asia can include a free stop in Hong Kong.

Alaska Airlines will give a free checked bag to cardholders and up to six other people.

The Alaska companion certificate is included in the welcome bonus and is valid every year on the account anniversary. The companion certificate allows you to bring a friend or family member on a round-trip, Alaska-operated flight in economy class for 99 cents plus taxes and fees, which can be a great strategy to get two people to Hawaii or to save money on expensive flights.

Bottom line

It is possible to get 70,000 bonus miles with the Alaska Mileage Plan. These are the most valuable miles out there. It's too good to pass up. It should be easy to redeem these miles for flights worth several thousand dollars, because it is the highest offer we have ever seen.

Don't wait. It's too late to take advantage of this offer, which ends on October 25.
