3,330+ Nautical Miles: The USAs 10 Longest Domestic Routes

US airlines plan over 5,200 domestic non-stop routes between July and September, including US territories. Analyzing every service using OAG data shows that the average distance is 667 nautical miles (1,236 km). While JetBlue ranks first for the highest average domestic stage length, it does not feature once in the country’s 10 longest airport pairs list. Given the routes that feature, that is entirely unsurprising.
