The bigger the waves, the bigger the discount.
That's the bases of Alaska Airlines' new sale for flights to and from Hawaii, in partnership with Surfline, a website which forecasts -- you guessed it -- surf conditions.
The airline will offer up to 30 percent off Hawaii flights according to data from 14 different locations around the Hawaiian islands. If the swells are less than 10 feet, you'll see 10 percent discounts on flights. If the swells are between 11 and 15 feet, you'll get a 15 percent discount. For swells between 16 and 20 feet, you'll get 20 percent off. And swells larger than 21 feet will result in a 30 percent discount. The deals will change daily around noon and 5 p.m. PST.
The deal runs through Nov. 8 and is valid for flights through Nov. 20, so act fast.
