Delta is the sixth-oldest operating airline by foundation date, and the oldest airline still operating in the United States. The company's history can be traced back to Huff Daland Dusters, founded in 1924 in Macon, Georgia as a crop dusting operation. The company moved to Monroe, Louisiana, and was later renamed Delta Air Services, in reference to the nearby Mississippi Delta region, and commenced passenger services on June 17, 1929. Among predecessors of today's Delta Air Lines, Western Airlines and Northwest Airlines began flying passengers in 1926 and 1927, respectively.
In 2013, Delta Air Lines was the world's largest airline in terms of scheduled passengers carried (120.6 million), and the second-largest in terms of both revenue passenger-kilometers flown (277.6 billion) and capacity (4.4 billion ASM/week; March 2013).
As of March 2015, Delta operates more than 5,400 flights per day. Delta Connection operates 2,533 daily flights. It is one of the few airlines to fly to all six inhabited continents, along with Air Canada, Air China, British Airways, Emirates, Etihad Airways, Korean Air, Qantas, Qatar Airways, Singapore Airlines, South African Airways and United Airlines. Delta is the only US carrier flying to Accra, Bangkok, Copenhagen, Dakar, Johannesburg, Moscow, Prague, Reykjavik, and Stuttgart.
