United Airlines and Delta Air Lines are set to operate narrowbody flights from the US to Europe in 2025, with United offering more routes compared to Delta. According to Cirium Diio data, these two airlines account for 16% of all take-offs on such routes this year, a slight decrease from the previous year.
Delta's operations are primarily concentrated during the summer months, while United has significantly increased its activity during this peak period. In August alone, United plans an average of 19 daily departures. During the third quarter, both airlines will operate nearly one in four transatlantic services.
United Airlines has planned 20 European routes using single-aisle aircraft for 2025. Notable changes include shifting Newark-Lisbon and Chicago O'Hare-Dublin from narrowbodies to larger aircraft like the Boeing 787s. However, United introduced new narrowbody routes such as Newark-Bilbao and Newark-Faro.
