21 Airlines: A Look At Boston’s International Flight Operations This Summer

Boston is one of 41 US airports to have non-stop European passenger flights this coming June-September. Analysis of Cirium schedules data shows that Boston is the country's fourth-busiest airport for Europe-bound services, behind only New York JFK, Newark, and Chicago O'Hare. Despite this, the scale of activity from the US is such that Boston only accounts for about 7.5% of peak summer flights, about one in 13.
