Delta Air Lines, in partnership with KLM, operates robustly between the United States and Amsterdam, maintaining a significant number of daily flights. This collaboration stems from their joint venture with Air France-KLM and Virgin Atlantic, aiding each airline in reaching a substantial flight capacity. Together, they plan up to 33 daily departures bridging the US and Amsterdam. This partnership has resulted in nearly 80% of flights on this route, with Delta controlling between 14 and 17 flights and KLM taking responsibility for 11 to 16 flights.
According to Cirium Diio data, the airlines have planned 24 routes between May and October 2025, with Delta operating nine of them while KLM handles 15. Additionally, 19 airport combinations are proposed which include seasonal flights from Miami and Orlando. San Diego will join the list following KLM’s inaugural service on May 8.
Delta and KLM are set to provide maximum service on 10 specific dates throughout the period examined. These airlines hit their all-time high of 35 daily departures in 2019, showcasing strong demand in the pre-pandemic era. On June 2, for instance, they are expected to deploy eight A330-300s, marking this aircraft as the prevalent choice for their transatlantic ventures.
