Delta Air Lines is making adjustments to its winter plans. The Atlanta-based carrier has made several cuts to its transatlantic schedule this winter, especially from its hubs at New York JFK Airport and Hartsfield-Jackson Atlanta International Airport. The size of the frequency reductions vary by market, with some routes getting hit harder than others.
Delta and other carriers serving the US are facing uncertainty over air travel demand. While revenues from transatlantic flying are up from previous years, airlines are closely monitoring demand patterns as economic conditions and consumer sentiment threaten to shift in the United States. However, these flight changes might also reflect seasonal demand changes in the slower travel months.
Delta Cuts Transatlantic Frequency

Delta is cutting frequency on several routes across the Atlantic starting as early as this November, according to aviation data analytics firm Cirium. Atlanta and New York JFK will see the most cuts, but Boston and Detroit will also see some reductions in the winter season. These reductions range from modest to major changes.
Meanwhile, on the other side of the Atlantic, destinations like Paris and Frankfurt will be hit hardest, but select destinations in Italy and Spain will also see reductions. There seems to be a mix between predominantly business and leisure destinations, making it unclear exactly what is behind the frequency changes.
Delta did not provide any further information to Simple Flying regarding the flight reductions, indicating it had shared everything in its recent earnings call. The carrier explained in its Q1 2025 report that transatlantic revenue had been up 5% from the previous year, indicating that demand for transatlantic flying was still strong. However, the airline is slowing capacity growth, and is shrinking its initially planned European schedule.
JFK and Atlanta Were Hit The Hardest

Delta Air Lines' Atlanta and New York hubs saw the highest number of routes facing frequency reductions. New York serves as one of the airline's primary transatlantic gateways, while Atlanta is one of the airline's best connected hubs. The complete list of impacted routes and their respective initial reductions is as follows:
Route Flight Reductions (Weekly)
Atlanta to Barcelona 1
Atlanta to Paris 4
Boston to Dublin 1
Atlanta to Rome 1
Detroit to Frankfurt 1
Atlanta to Frankfurt 1
Atlanta to Lagos 1
Atlanta to Madrid 1
Atlanta to Munich 1
New York JFK to Milan 3
New York JFK to Venice 1
It is worth noting that some of these reductions extend into subsequent months, while others are more isolated. Most notably, Atlanta to Paris, Atlanta to Frankfurt, New York to Milan, and New York to Venice have reductions that span at least two months. Any of these cuts could last longer based on demand patterns.

A Variety Of Jets Operate These Routes

Delta has a large and relatively diverse fleet of long-haul jets. In recent years, the airline has favored Airbus over Boeing, opting for next-generation jets like the A330neo and A350. The A350 and A330, including the A330-200, -300, and -900neo all operate some of the impacted routes mentioned above. However, the A350 only appears once, operating services between Atlanta and Lagos.
Despite its age, Delta also relies heavily on the Boeing 767-400ER. The jet appears several times on this list, including on both routes from New York to Italy and flights from Atlanta to Munich, Madrid, and Barcelona. All of these jets will now be operating these routes less frequently than originally planned.
