AirTran Airways' principle of delivering the best flying experience to smart travelers includes a strategy of reducing emissions from aircraft operations.

Our Efforts to Reduce Emissions

  • Our fleet upgrade from DC-9 aircraft to Boeing 717 aircraft produced a 56% reduction in low altitude emissions, reducing emissions per seat from 303 grams to 134 grams.
  • Our fuel conservation efforts provide further emission reductions:
    • Single-engine taxi operations
    • Reduced APU operations in favor of ground air sources
    • Reduced Thrust Takeoff Profiles on both 717 and 737 aircraft further reduce low altitude emissions
    • Installation of Aerodynamic Efficient Blended Winglets on 737 aircraft

US Airline Engine Emissions Comparison

Emissions Comparison (NOx, CO, and HC) by Seat based on ICAO Engine Sampling Data* — Top 10 US Air Carriers by ASM

Emissions Comparison

* ICAO sample data reports low altitude emissions by takeoff, climb, descent and landing phase of flights — defined as an LTO cycle (see notes below for details).

Information on how emissions information was calculated

All information was obtained from the ICAO Engine Exhaust Emissions Data Bank.

  • Emissions indices used for study: Oxides of Nitrogen (Nox), HydroCarbons (HC) and Carbon Monoxide (CO)
  • Emissions are measured for each engine over its LTO cycle for total emissions emitted in grams.
  • LTO cycle is measured as one take-off, climb, approach and idle operation of a single engine.
  • US Operator Data is from calendar year 2006.
