Where United Airlines Is Flying Its High Capacity 364-Seat Boeing 777s

by Staff


  • United Airlines’ non-Extended Range Boeing 777-200s have 364 seats in an economy-heavy, premium-light configuration.
  • They are used on high-capacity, short- to medium-range leisure routes.
  • Los Angeles-Honolulu, Chicago O’Hare-Orlando, and Denver-Washington Dulles are the most-served routes in February.

United has 19 so-called ‘domestic’ Boeing 777-200s, based on ch-aviation information, although not all are active. They are the non-ER versions and the original 777 variant. Few of the medium-haul aircraft were produced and even fewer remain. United’s non-ER aircraft have had more seats added over the years, changing their economics and use. (It is a shame the above photo was not in the new livery, but I like it.)

A summary

The non-ER 777-200s have 364 seats, including the dreaded 3-4-3 layout in economy, although that is less problematic on the routes on which they fly. The high-capacity, leisure-heavy, medium-range 777-200 has low seat-mile costs, helped by being paid off, influencing where they are used.

Aircraft include N774UA, the second 777 to roll off the production line. At 29.6 years old, the high-cycle aircraft is the world’s oldest active Triple Seven. It was delivered to United in 1996, making the carrier the launch customer of the variant – and the 777 generally. The image below is from 2000. (My favorite registration is still N777UA.)

According to Flightradar24, on February 9, the day I am writing this article, N774UA arrived in Chicago O’Hare from Los Angeles at 05:39. It will fly to Denver before continuing to Honolulu, where it will stay overnight.

Where the non-ERs are flying

Analyzing schedules using Cirium data shows that the 364-seat aircraft were used to Europe as recently as 2019 and to Asia until 2020 (although only from Guam). Things have changed considerably.

The map below shows where they are scheduled to fly in February. Las Vegas only appears because of the Super Bowl. The shortest route is just 414 miles (666 km) between San Francisco and Los Angeles, while the longest is the 3,904-mile (6,283 km) link from Houston Intercontinental to Honolulu.

Across all airport pairs, the average stage length is 1,950 miles (3,138 km). In February 2019, when they were used to Europe and more, it was 3,797 miles (6,111 km). (Shame it wasn’t 6,777.)

There are a typical 45 daily flights by the non-ER 777s in February. Denver sees the variant the most, followed by Chicago O’Hare, Honolulu, Houston Intercontinental, and Los Angeles. Notice that Newark does not have flights in the examined month, but they return on March 31, the day northern airlines switch to summer schedules.

Served up to double daily

Ignoring a handful of routes that will see high-density equipment either on a one-off or otherwise very infrequent basis, 14 routes will be daily. Naturally, many are hub-to-hub services, which, of course, also connect major cities. They also include all three international airport pairs: daily from Chicago O’Hare, Denver, and Houston Intercontinental to Cancun.

A further six routes will operate almost, but not quite, daily. But those airport pairs with the most flights this month are as follows:

  • Los Angeles to Honolulu: double daily ‘domestic’ 777-200 flights
  • Chicago O’Hare to Orlando: double daily
  • Denver to Washington Dulles: up to double daily
