What is one environmental initiative that Frontier Airlines has adopted?

Investing in fuel-efficient aircraft is a significant environmental initiative adopted by Frontier Airlines as it directly contributes to reducing the airline's carbon footprint. By incorporating newer models that utilize advanced technology and more efficient engines, the airline decreases fuel consumption per passenger mile.
