São Paulo-Chicago is United's only South American route on the list, spanning 5,222 miles in approximately 10 hours and 30 minutes.

United Airlines’ five longest operations with the Boeing 787-10 for September 2024 have some of the most interesting readings. According to data from Cirium, an aviation analytics company , United has a total of thirty operations on each of these routes. UA offers some of the best seating options onboard its 787-10s.



The carrier is offering 9,540 seats in September, and this equals 318 seats per departure (for all the routes discussed). In this article, we will dive deeper into the numbers behind United Airlines’ five longest routes with the Boeing 787-10. 5 Rome - Chicago The route with the lowest ASMs on this list.

United operates its Boeing 787-10 from the busiest airport in Italy, Leonardo da Vinci–Rome Fiumicino Airport(FCO), to the sixth-busiest airport in the world, Chicago O'Hare International Airport(ORD). Let’s take a look at the length of the route, and the ASMs on this route: Distance (miles) ASMs 4,823 46,011,420 United's Boeing 787-10s take 10 hours and 25 minutes to complete this journey. The only American carrier that United competes with for direct flights on this route is American Airlines , which deploys its Boeing 787-8s on this route.

Other carriers offering direct flights from FCO to ORD (and ORD to FCO) include ITA Airways, and Ethiopian Airlines. While Ethiopian also uses the same aircraft type that American uses on this route, ITA is the only carrier using an Airbus. ITA’s Airbus A330s, much like the aircraft of other carriers operating directly between FCO and ORD, fly daily between these airports.

4 Athens - New Jersey Competing only with Emirates on this route. The Boeing 787-10s operated by United Airlines from Athens International Airport to Newark Liberty International Airport (EWR), New Jersey covers a distance that is a tad shy of the 5,000-mile mark. The flight is completed in 10 hours and 45 minutes.

Emirates offers flights on the ATh-EWR route on its Boeing 777-300ERs, and the flight is around 20 minutes longer than the one offered by United’s Boeing 787-10s .
