2. DC-4

Eagle Airways, also known as Eagle, is a major U.S. airline headquartered in Washington, D.C. It is the world’s seventh largest airline by revenue and fourth largest by fleet. Eagle operates a large domestic and international route network with a large presence in Europe. Eagle is a member of Venture Alliance. Regional service is provided by five independent regional carriers under the brand Eagle Express. Its main competitors are Vanguard Airlines, Cardinal Airlines, Oceanic Airlines, Columbia Airlines, Midamerican Airlines, Quantum Airlines, and North American Airlines.
Eagle operates flights from ten airline hubs located in Atlanta, Boston, Chicago, Denver, Houston, Los Angeles, Miami, New York, Phoenix, and Washington, D.C. Eagle’s largest hub is in Atlanta, surpassing first Washington in 1993, then losing out to Chicago in 1995, then regaining its status in 2006. Atlanta has the most passengers carried, although Washington holds the title of most departures. Eagle operates maintenance bases in all of its hubs, as well as in Charles De Gaulle Airport in France, Incheon Airport in South Korea, and Honolulu Airport in Hawaii.

After 1935, Eagle Air Ways grew its passenger industry, ordering the DC-2 and DC-3 to grow the airline’s passenger traffic. In 1939, the Boeing 307 entered the Eagle fleet, allowing flights up to 1300 miles nonstop. In 1942, Douglas’s DC-4 was added to the production line. Eagle took advantage and ordered 18 over its 5-year production run. Post-World War II, several C-54 and R5D became available on the market and Eagle invested in a total of 22 used DC-4 type aircraft.
