Metric Defined
Jet fuel from mainline + Connection Carrier operations2
Number of paying passengers multiplied by the distance they traveled in miles
Weight, in U.S. tons, of paying passengers multiplied by the distance traveled (assumed 220.5 lbs per passenger, including luggage)
Weight, in U.S. tons, of revenue generating cargo multiplied by distance traveled
Sum of passenger and cargo revenue ton kilometers
Fuel efficiency on a payload-kilometer basis
Number of seats available to sell multiplied by the distance traveled
Fuel efficiency on a capacity basis

  1. Totals may not sum due to rounding.
  2. Consistent with prior period reporting, this table excludes data from Delta Private Jets (DPJ) for all periods that DPJ was owned by Delta.
  3. Previously stated figures in revenue ton miles (RTM) are now stated in revenue ton kilometers (RTK) to align with our SBTi goal and guidance.
  4. Fuel efficiency / RTK was impacted in 2020 and 2021 by lower passenger loads during the COVID-19 pandemic and Delta’s middle seat blocking measures through April 30, 2021.
