The 3.1% cull means Air France-KLM’s Dutch unit will lose rights to 5,700 flights in 2024 from the just-completed summer season, including the low-cost Transavia operation. Delta Air Lines Inc., a transatlantic partner to Air France-KLM, has been told to cut 252 takeoffs and landings, and EasyJet Plc will lose 693.

Delta has begun legal proceedings against the decision for conflicting with “national, European and international regulations,” the airline said in a statement. “This decision is in violation of the U.S.-EU Open Skies Agreement and will negatively impact consumers,” the airline said, adding that it believes it’s possible to balance sustainability priorities with passengers’ desire to travel.
