Major airlines across the Northern airlines will transition to their summer timetables on March 30. During the height of summer travel, when passenger numbers, available seats, and ticket prices reach their annual maximum, over 35 commercial carriers will provide service between the United States and European destinations.
Airlines from the USA will start 25 routes
American, Delta, JetBlue, and United are all launching new transatlantic connections. More than half represent entirely new nonstop markets, including Delta’s service from New York JFK to Catania and United’s Newark to Palermo route. These will complement Italian carrier Neos’ existing Palermo-JFK service that began in 2024, bringing the total number of airlines offering US-Sicily flights to three.

Carriers from Europe will begin 15 routes
The following routes include two unprecedented services to Nashville, centered around hub connections for each respective carrier. Both will utilize narrowbody aircraft, capitalizing on their lower capacity and operational costs compared to widebody planes. This approach reduces financial risk by requiring fewer passengers to achieve profitability. Such routes would be economically unfeasible without single-aisle equipment.
