More than 35 airlines operate passenger flights between the US and Europe, with some offering unique routes such as Air Tahiti Nui's Papeete-Los Angeles-Paris CDG service and Emirates' Dubai-Milan Malpensa-New York JFK route. Despite the diverse offerings, Hainan Airlines is excluded from consideration due to its US-European leg not being bookable.
According to Cirium Diio data, over 92,900 passenger flights are scheduled from the US to Europe between February and July 2025. This marks a growth of 3.1% compared to the same period in 2024 and an increase of 11.1% from pre-pandemic levels in 2019.
The analysis focuses on percentage growth, highlighting smaller operators like Italy's Neos. Notably, Turkish Airlines, Aer Lingus, and Icelandair rank among the top ten by take-offs. United remains the largest operator across this market segment with a 5.3% increase in services.
