The peak summer has arrived. Examining Cirium data shows that approximately 100 foreign passenger airlines will serve the US between July and September.

The US’s top foreign operators
The following table summarizes them. Air Canada is, of course, number one. It has an average of 200 daily US flights (each way) in the three summer months, and its network comprises 95 airport pairs. When all US and foreign airlines are combined, it has about one in every 12 international departures.

But that is not the end of its changes.
These figures are for the three months; they will vary at other times. Daily services are averaged (flights/92 days), with half of the days having more and half having fewer. For fairness and consistency, all units of each airline are combined. Airport pairs are non-stop only to avoid double counting.
