I am not familiar with how the air miles on credit cards work. If I were to get the Alaska card, how much money would I have to spend in a year in order to get tickets....and how many would I get? If I understood the Jet Blue card, I had to spend like $20,000 to get a single ticket. That didn't seem like a great deal.
Well, I use a combination of things. First, I have a frequent flier account with Alaska, so that accumulates miles. Check out their website (alaskaairlines.com); there are always promotions going. You get miles flown, sometimes double miles for certain destinations, miles on their partner airlines, miles for other places like car rentals.
Second, with an Alaska credit card, you get one $50 companion ticket every year-basically, buy one ticket, get the second for $50. That's a great deal-saves several hundred dollars, and it's very easy to redeem. Right now, in addition, the bonus for getting the card is ...20,000 miles, so there's your first ticket.
Third, this is my only credit card. You'll get a mile per dollar; two miles for every dollar spent on Alaska or Horizon tickets.If you're really good about paying off your card every month, do what we do: put as many regular bills onto your card, then have an automatic payment from your checking account in the same amount every month. I know folks who've paid mortgages and college tuition. Even if you just pay, say, utilities, cel phone, phone, groceries, you could easily accumulate 10,000 more miles a year and not have paid any interest.
I'd just add that I'd fly Alaska and Horizon whenever possible without being a member of their mileage plan. Their customer service is almost always head and shoulders above other airlines. And on Horizon, you even get a free glass of wine or microbrew!
