This article is about the airline. For other uses, see Delta (disambiguation).

Delta Air Lines (NYSE: DAL) is the 2nd largest passenger airline in the world by available seat miles. Extreme competition in the industry has limited Delta's ability to raise prices to their natural supply/demand and cost reflective levels. As a result, Delta was forced into bankruptcy in September of 2005.^[1] During the following few years, Delta decreased its number of aircraft types in an effort to reduce maintenance costs. On October 2008, Delta and Northwest merged to form a new joint airline called "Delta," which is the largest airline in the world by both enterprise value and available seat miles.^[2]
