Spirit Airlines is encouraging travelers to bring on the hate, and get free miles by doing so.

As part of their "Hate Thousand Miles Giveaway," frustrated travelers can receive up to 8,000 free Spirit miles when they vent about any airline.

“We want to change the way people think about air travel and educate them about the Spirit way of traveling” said Ben Baldanza, Spirit’s CEO.

Additionally, customers who don’t have any hate can tell the airline about a good time they had saving on Spirit and also get 8,000 free Spirit miles.

“We know many customers love us and our approach to air travel,” continued Baldanza.  “We’re confident once the haters see how we’re different, and how much money they can save, they’ll learn to love us, as well.”

The airline is giving away a billion miles in all.
