10-Hour Domestic Flights: The 6 Longest Nonstop Flights Within North America

Credit: Toni. M | Shutterstock, Simple Flying Published Nov 1, 2026, 10:00 AM EST Brandon's passion for aviation started at a young age. He became involved in the flight simulator and VATSIM communities, which sparked his interest in aviation and eventually led him to earn his private pilot license. Outside of work, he continues to build flight hours, explore new airports, and stay involved in the aviation community. Sign in to your Simple Flying account Every one of the longest domestic flights in the United States ends in Hawaii. The top six range from 4,502 to 5,095 miles and from 10 hours, 21 minutes to 11 hours, 40 minutes westbound, which puts several of them ahead of transatlantic routes from the same airports. Boston to Honolulu is longer than Boston to London Heathrow. From Logan, a passenger can reach Europe faster than Hawaii without ever leaving the country or showing a passport. Ranking them by distance produces a list that does not match the one-block time list. Newark to Honolulu ranks third by distance at 4,962 miles but second by scheduled time at 11 hours, 28 minutes, ahead of JFK to Honolulu. Three of the six are within two minutes of each other westbound. The list is also unstable, because most of these routes are seasonal. Boston runs for 16 days this winter after Delta Air Lines cut 81% of the schedule it announced in February. Newark to Kahului operates once a week for a fortnight. Only JFK to Honolulu and Atlanta to Honolulu run reliably year-round. 6 Atlanta–Honolulu 4,502 miles (7,246 km) Credit: Kevin Hackert | Shutterstock Delta's longest domestic route from Hartsfield-Jackson Atlanta International Airport (ATL) runs 4,502 miles (7,246 km) to Honolulu with a maximum block time of 10 hours 21 minutes. It is the only route in this ranking operated from a carrier's primary hub rather than a secondary gateway, which changes its economics considerably. Delta flies it with the Airbus A330-300, occasionally substituting the Boeing 767-300ER, at a frequency ranging from daily to twice daily depending on the season. The airline added a second frequency three times weekly from January 4, 2027, also on the A330-300, as part of the same February 2026 announcement that brought Boston back. Boston lost 81% of its schedule. Atlanta gained capacity. Connecting traffic explains the difference. Atlanta is the busiest airport in the world by passenger numbers and the center of Delta's domestic network, which means a Honolulu departure filled with passengers from across the southeastern United States rather than from Atlanta alone. Simple Flying reported that booking data for Boston showed almost nine in ten passengers flying the route as a local round trip, which is the opposite of what a hub route produces. Atlanta to Honolulu is 593 miles shorter than Boston to Honolulu and nearly 80 minutes quicker westbound, and it is the one Delta is expanding. 5 Washington Dulles–Honolulu 4,817 miles (7,752 km) Credit: Matheus Obst | Shutterstock Washington Dulles International Airport (IAD) to Honolulu covers 4,817 miles (7,752 km) with a maximum block time of 10 hours 58 minutes. United Airlines operates it, and like Newark to Honolulu, it uses the Boeing 767-400ER. The frequency pattern makes it one of the harder routes on this list to catch. Simple Flying recorded United operating it anywhere from Saturday-only to daily, depending on the season, with 137 flights each way across a full year in one measured period and 18 flights in each direction during a single sample month. A Saturday-only widebody service on a nearly 5,000-mile domestic sector is unusual scheduling, and it means the route effectively exists as a weekly option for much of the year before scaling up around peak demand. United has previously restored it to daily summer service after initially planning once-weekly flights, so the pattern shifts between seasons. Dulles is the smaller of United's two East Coast Hawaii gateways. Newark is the airline's primary long-haul hub on that coast, and the Honolulu service from Dulles operates alongside rather than in competition with it. The 767-400ER fleet is small enough that United assigns the type carefully, and the Washington route draws on the same aircraft as Newark. For anyone specifically chasing the 767-400ER, Dulles to Honolulu and Newark to Honolulu are the two longest domestic opportunities, and both are seasonal. 4 Newark–Kahului 4,903 miles (7,890 km) Credit: Carlos Yudica | Shutterstock Newark Liberty International Airport (EWR) to Kahului Airport (OGG) on Maui covers 4,903 miles (7,890 km), making it the fourth-longest domestic nonstop route, ahead of Washington Dulles to Honolulu. Westbound block time is 11 hours 26 minutes, identical to JFK to Honolulu, with the return scheduled at 9 hours 33 minutes. The operation is unusually limited. United flies it once a week as UA442 outbound and UA441 returning, with nonstop service running from December 19, 2026, into early January 2027. A passenger wanting to fly it has a handful of dates rather than a timetable. Outside that window, the route disappears entirely, and United routes Newark to Maui traffic through connections at San Diego, Denver, Portland, Seattle, or San Francisco. The route was added in December 2021 as a pandemic-era move to capture leisure demand, and United has operated it seasonally since. The aircraft is the Boeing 767-300ER in a 270-seat layout rather than the 767-400ER used on the Honolulu services. Maui's position in the rankings reflects geography rather than market size, with Kahului sitting slightly farther from the East Coast than Honolulu, which pushes this route above Dulles-Honolulu despite Honolulu being by far the larger market. It also illustrates how unstable the bottom half of this list is. A route flying once weekly for a fortnight occupies the same rank by distance as one flying daily year-round. 3 Newark–Honolulu 4,962 miles (7,985 km) Credit: Robin Guess | Shutterstock United Airlines operates Newark Liberty International Airport (EWR) to Honolulu at approximately 4,962 miles (7,985 km), making it the third-longest domestic route by distance and just 21 miles shorter than JFK to Honolulu, according to Cirium data. FlightConnections lists the sector at 4,951 miles, so the figure varies slightly by provider. By block time, it ranks second at 11 hours 28 minutes, two minutes longer than JFK, which is a reminder that distance and scheduled time do not order these routes identically. The aircraft is the draw for enthusiasts. United assigns the Boeing 767-400ER, the stretched variant of the 767 that Boeing built in small numbers and that United is one of the few operators still flying. Simple Flying recorded the type in a 231-seat layout on United's Hawaii services. Finding a 767-400ER on a scheduled passenger service at all is unusual, and Newark to Honolulu is among the longer sectors United assigns it. The schedule is not year-round. United operates the route seasonally, ranging from three weekly to daily depending on the period, which means it disappears from the rankings for parts of the year. That seasonality reflects the same calculation Delta made in Boston. East Coast flying to Hawaii concentrates in winter, when mainland travelers want the islands and transatlantic demand softens. The difference is that United scales the frequency rather than withdrawing the route, which has kept Newark to Honolulu on the map through periods when Boston vanished entirely. 2 New York-JFK–Honolulu 4,983 miles (8,019 km) Credit: Minh K Tran | Shutterstock With Boston operating for barely two weeks, New York John F. Kennedy International Airport (JFK) to Honolulu is the longest domestic route flying for most of the year. It covers 4,983 miles (8,019 km) with a maximum block time of 11 hours 26 minutes, placing it 112 miles behind Boston on distance and 14 minutes behind the scheduled time. Two airlines operate it. Delta flies the route with the Boeing 767-300ER and increased frequency from five times weekly to daily on April 1, 2026. Alaska Airlines operates it daily with the Airbus A330-200, acquired from Hawaiian Airlines following their merger. That gives the city pair two daily widebody rotations year-round, which is a materially stronger position than Boston ever achieved and the clearest explanation for why one route survives while the other does not. New York's advantage is scale. The metropolitan area is roughly three times Boston's population, and the base of corporate and high-income leisure travelers that fills premium cabins on an 11-hour flight is correspondingly deeper. Both carriers also feed the route from connecting networks, with Delta routing passengers through JFK and Alaska connecting traffic through its own system. Where Boston relied on local round-trip demand for close to 90% of its passengers, JFK draws from a wider catchment and a larger pool of connecting itineraries. The route has been served continuously while Boston has been suspended, resumed, cut, and suspended again. 1 Boston–Honolulu 5,095 miles (8,200 km) Credit: Felix Tchvertkin | Shutterstock The longest domestic route in the United States connects Boston Logan International Airport (BOS) to Daniel K. Inouye International Airport (HNL) in Honolulu, covering 5,095 miles (8,200 km) with a maximum block time of 11 hours 40 minutes. It is longer than Boston to London Heathrow, which means a passenger can reach Europe faster than they can reach Hawaii from the same airport without leaving the country. The route has a complicated recent history. Hawaiian Airlines operated it until November 19, 2025. Delta flew it from November 21, 2024, through April 30, 2025, then did not operate it in winter 2025-2026. Delta announced in February 2026 that it would resume on December 19, 2026, initially daily before dropping to four times weekly through the winter on the Airbus A330-300. In late August, Delta cut 81% of those planned departures. The route now operates only from December 19 to January 3, 2027, with the final Honolulu return landing on January 4, and Delta has said it will not return in winter 2027-2028. The underlying problem is the shape of the demand. Simple Flying reported that booking data shows almost nine in ten passengers flew Boston to Honolulu and back as a round trip rather than connecting onward, leaving a 282-seat widebody almost entirely dependent on local traffic between two cities 5,095 miles apart. Department of Transportation figures show 149,800 round-trip local passengers through March 2025, roughly 410 per day in each direction. For anyone wanting to fly the longest domestic route in the country, the window is a 16-day period over the holidays.
