Ever rented a car in Colorado and wondered about that extra $3 daily fee? It’s here to stay. The American Car Rental Association tried to have it tossed, claiming it violated federal aviation tax laws, but a federal appeals court shut that down this week. The judge ruled the fee targets consumers, not rental businesses, so the aviation law doesn’t apply. If you’re road-tripping the Rockies and need a rental, you’ll still pay those extra bucks.
