One airline is giving away seats on its airplanes to promote a Green Week, from Tuesday to August 20.
The airline, Frontier, is also offering the promotion to emphasize its efforts to become the most green airline.
There is one catch for the deal: You must have a green name.
People with the last name of Green or Greene can claim a free domestic flight.
For the promotion, the company is not accepting people with names like Solar, Wind, Recycling, or any other green term.
Green and Greene people must book and pay for their flight. The airline will send them a refund later on.
The refund maxes out at $400.
Qualified participants must act quickly. The airline requires that people book the flight that departs on Aug. 13.
