With Southwest Airlines now offering flights to Hawaii, other airlines that offer service to the Hawaiian islands are feeling the competition. Alaska Airlines is responding to the competition by introducing an interesting promotional offer. The airline is now offering discounts on flights to the islands based on the size of waves.

The airline will work with well-known surf-forecasting firm Surfline, which will supply the data. Long story short, Alaska Airlines will offer bigger discounts when the waves are bigger.

The promotion is called Swell Deals and will run from November 4 until November 8. Keep in mind all travel must occur before November 20. The discounts will be available for flights to Kona, Maui, Honolulu and Lihue. Essentially, the bigger the wave, the bigger the discount offered. The maximum discount travelers can receive is 30 percent.

The data that will be used will come from 14 popular surf spots all over Hawaii, and the airline will update the discount two times a day, at noon and 5pm, PST. Discounts will be based on wave size and are as follows:

  • under 10 ft. swells, 10 percent off
  • 10-15 ft. swells, 15 percent off
  • 16-20 ft. swells, 20 percent off
  • 21 ft. or more swells, 30 percent off

The great thing about this promotion is that you don't have to be a surfer to save money on your next flight to Hawaii. Another huge advantage of this deal is that you can apply this discount for up to six flyers per reservation.

As travel trends change and flyers often book last-minute deals to far-flung destinations, promotions like this could become more common. In fact, Alaska Airlines hinted that it could offer similar deals for flights to ski destinations based on snow levels. Those wanting to get in on the current deal can do so by going to Alaska Airlines' website.
