Environment

Jet fuel consumed

Every gallon the airline reports to the US Department of Transportation (airline fuel cost and consumption report) — all scheduled and charter flights, domestic and international.

In June 2026, Frontier Airlines consumed 35,885,550 US gallons of fuel (33,698,093 on domestic and 2,187,457 on international flights), according to the US Bureau of Transportation Statistics — about 349,884 tonnes of CO₂.
