Personally, I'm tempted to start booking
flights through Expedia more often, because not only do you earn Expedia + Rewards points, but also you get points on
whatever credit card you use for the purchase, the shopping portal you click through to get to Expedia.com (like Chase Ultimate Rewards, which gives you an extra point per dollar spent), and through Expedia's Business Rewards program that is exclusively for Chase Ink Plus, Bold or Ink Business Cash cardholders.
