I, admittedly, haphazardly book flights after sourcing the best deals that I find on Vayama or Kayak. But, I realized recently that committing to riding a single airline may be worth the return in the long run.
This recent article shared that JetBlue boasts the best domestic frequent flier program. You earn points for every dollar spent which can also be applied to Hawaiian Airlines and Emirates flights (hello Dubai). Something to consider when you travel (or would like to travel) as much as we do!
NOTE: Among the worst domestic rewards programs? Delta and American *sadface.*
