Atlantic Southeast Airlines

Atlantic Southeast Airlines was the Atlanta-based regional that flew as Delta Connection. Delta sold it to SkyWest's parent company in 2005, and in 2010 and 2011 it was combined with ExpressJet. The combined airline kept the ExpressJet name from the end of 2011, so ExpressJet's page carries the story from 2012 on.

Who it flew for

Atlantic Southeast Airlines flew for more than one airline, and sometimes several at once. Our estimate of the split between them, which is based on the airports it serves, is too rough to publish for a regional like this. The summary at the top names its partners from public record.

Fuel

In 2011 Atlantic Southeast Airlines burned 178 million gallons of jet fuel, which is 42.9 seat-miles per gallon and about 0.285 kg of CO2 per passenger-mile. Over 500 miles that's roughly 143 kg per passenger. Small regional aircraft burn more fuel per seat than the mainline jets, and a short hop spends a larger share of its fuel on take-off and climb, so these figures aren't graded against the airlines on the main list. Their flying and fuel are counted in the airlines whose names are on the tickets.
