Category - Delta Air Lines

Delta Air Lines has become the most profitable airline in the United States. The carrier has been outperforming its main competitors (United Airlines and American Airlines) for quite some years now.

The airline is also the most international focused of the big 3 carriers with very strong transatlantic and transpacific operations which massively help increase yields during high and low seasonalities.

Delta is part of the SkyTeam alliance and shares a joint venture in transatlantic services with Air France-KLM and Virgin Atlantic. Also it has invested in some foreign carriers as it holds a 49% stake in Virgin Atlantic and a 10% stake in LATAM. It also has a joint venture standing with the Chilean-Brazilian airline which has helped significantly to increase connectivity offered towards south America.
