Other major departure points include Boston, Dallas, Atlanta, San Francisco, Miami, Washington, and Seattle, while secondary cities such as Charlotte, Philadelphia, Orlando, Houston, and Phoenix also have direct service, often on a single airline like American or Delta. Most transatlantic flights are overnight, with red-eye options common from the East Coast and Midwest, though West Coast departures typically arrive the next day due to the longer flight time. Travelers typically choose their departure city based on proximity and flight frequency—those near major hubs enjoy more schedule flexibility, while connecting through a larger U.S. gateway is common for those in smaller markets without nonstop service.", "methodology": "The U.S. departure cities with nonstop service to this destination and their weekly frequencies come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).
