During the summer, the United States is set to see up to 635 passenger flights daily to Europe, resulting in a considerable volume of transatlantic activity. According to data from Cirium Diio, over 40 airlines are scheduled to operate more than 500 routes between the two continents. On average, routes will have about eight weekly departures, with some operating up to eight times a day, such as British Airways between London Heathrow and New York JFK. Notably, 97 routes will have at least two daily flights, and 25 will feature three or more daily operations.
Within this landscape, a smaller subset of US-Europe routes will operate just weekly. These routes involve various European carriers and focus on point-to-point traffic. This limited frequency often targets specific customer segments such as vacation travelers and members of the diaspora. Among the airlines providing these services are Iberojet, TUI Airways, Azores Airlines, LOT Polish Airlines, Neos, and TAP Air Portugal.
The impact of these infrequent flights can lead to high occupancy rates, depending on the demand. For example, LOT Polish Airlines reportedly achieved a 92% seat occupancy rate between Kraków/Rzeszów and Newark in summer 2024, as per the US Department of Transportation. In contrast, Azores Airlines filled only 47% of its Terceira-New York JFK capacity over the same period.
