Frontier Airlines is notorious for expensive baggage fees, ever wondered why?
Frontier considers itself America's greenest airline. They claim that they are 43% more fuel efficient than competing airlines.
Their biggest cost saver is weight. The heavier a plane is, the more fuel it has to burn to move from location A to location B.
Frontier wants you to pack light for their flights. Excessive baggage causes more weight and forces the airline to spend more on fuel. The high baggage fees act as an incentive not to bring extra bags on the plane but also to compensate for the fuel needed if the extra baggage needs to fly.
