Sustainability Score

Frontier Airlines demonstrates mixed commitment to sustainability practices. While they operate one of the most fuel-efficient fleets in the US and have made strides in reducing single-use plastics, their transparency regarding comprehensive ESG metrics could improve. Their labor practices have faced criticism, and their environmental reporting lacks detail in several areas. The airline has made some progress in reducing their carbon footprint but falls short of industry-leading sustainability standards.
