Top 10 longest narrowbody flights in 2025

There was a time when, if you wanted to cross the Atlantic or fly to another continent, you’d have to take a widebody aircraft; single-aisles were purely for short-haul and regional flights. But things are changing, and today’s longest narrowbody flights see airlines flying thousands of miles, sometimes for more than eight hours at a time.

With the help of global travel data provider OAG, we check out the top 10 longest narrowbody flights scheduled for summer 2025. All in, 57 routes will see single-aisle aircraft flying more than 3,000 nautical miles. 

Fasten your seatbelt, because some of these flights are knee-achingly long.

The A321LR operates six of the top 10 longest narrowbody flights

Leading the pack for the longest narrowbody flights scheduled this summer season is French all-business class airline La Compagnie. Its longest route covers 3,473 nautical miles (NM), using the capable A321LR, and flies from Newark Liberty (EWR) just outside of New York to Milan Malpensa (MXP).

In fact, La Compagnie will operate both the longest and second-longest narrowbody flights, as its Newark to Nice (NCE) route clocks in at just two nautical miles less, at 3,471 NM. This route, too, uses the A321LR in La Compagnie’s all-business class arrangement. 

Coming in third is Air Transat with its route from Lima (LIM) to Montreal (YUL), which it operates using… you guessed it, the A321LR. Air Transat is set to get the A321XLR, but not until late 2025 into 2026.

In fact, six of the top 10 longest narrowbody flights this summer will see A321LR equipment deployed, showcasing the incredible commercial power of this high-capacity single-aisle globetrotter. But we also see an appearance of Boeing’s rival aircraft, the 737 MAX, the shiny new even longer-range A321XLR, and the original ‘flying pencil,’ the Boeing 757.

Revealed: The top 10 longest flights in the world in 2025

1: La Compagnie: Newark – Milan

3,473 NM / 3,997 miles / 6,431 km

Flightradar24RouteEWR-MXPFlight numberB0301Block time7 hours 55 minsAircraftA321LRFlights in S25332Officially the king of the world’s longest narrowbody flights, La Compagnie operates this huge trek from just outside Milan to Newark, near New York. Brushing close to 4,000 miles, it’s operated by the Airbus A321LR, of which the airline has two.

Incorporated as ‘DreamJet,’ La Compagnie is a French airline with a rather interesting business model. Its aircraft are outfitted in an all-business class arrangement, where passengers are treated to fully lie-flat seats and 15.7-inch (40 cm) seatback touchscreens.

Although the airline is headquartered at Paris Orly (ORY), its route between Milan and Newark has become a core service. Launched in 2022, the route is operated year-round alongside Paris to Newark, while Nice joins for the summer season only. 

The airline announced plans in 2023 to add more A321LRs to its fleet and begin serving new destinations. However, the next aircraft isn’t due to arrive until September 2026, according to FlightGlobal, so it will be some time before we see any more mega routes from this airline.

2: La Compagnie: Newark – Nice

3,471 NM / 3,994 miles / 6,428 km

Flightradar24RouteEWR-NCEFlight numberB0201Block time7 hours 45 minsAircraftA321LRFlights in S2592La Compagnie’s seasonal Nice to Newark service operates only 92 times this summer, targeting wealthy travelers heading to Cannes, Monaco and Saint-Tropez. At just two nautical miles shorter than the Italian connection, it grabs the glory of being the second-longest narrowbody flight in 2025.

These two flights, while not close to the ultimate range of the A321LR (4,000 NM), would be bumping up against reserve fuel requirements if they were fully loaded. Commercial jets need at least 30 minutes of ‘spare’ fuel in the tank, in case they’re required to hold before landing.

La CompagnieBut with La Compagnie, having only 76 seats on board brings a weight-saving advantage, lowering fuel burn and giving it more than enough range for these trips. That’s reflected in the lower-than-usual block time allocated to the services, suggesting the airline has the luxury of flying a little bit faster, thanks to its lighter load.

3: Air Transat: Lima – Montreal

3,404 NM / 3,917 miles / 6,304 km

Flightradar24RouteLIM-YULFlight numberTS151Block time8 hours 20 minsAircraftA321LRFlights in S25120While La Compagnie might operate the two longest narrowbody flights in the world this year, Air Transat puts in a great show for very long services. Using its A321LR, it flies the third longest route from its home in Montreal nonstop to Lima in Peru. It’s one of 12 routes operated by Air Transat’s single-aisle that are over 3,000 nautical miles!

The route to Lima launched in December 2023 and is operated year-round. As a leisure-focused airline, the route performs well with tourist traffic to South America and connects Peruvians in Canada with their families back home.

It should be noted that Air Transat announced a return to Germany after a decade, touting a service to Berlin for summer 2026. At over 3,500 nautical miles, it will easily be the longest narrowbody flight in the world next year, should no other airline announce something longer.

4: United Airlines: Stockholm to Newark

3,404 NM / 3,917 miles / 6,304 km

Flightradar24RouteARN-EWRFlight numberUA69Block time8 hours 40 minsAircraftBoeing 757Flights in S25176Although the Boeing 757 is becoming something of a rarity in our modern skies, it still features heavily on some of the longest narrowbody flights in the world. When we look at all the flights over 3,000 NM in summer 2025, 12 of the services use the Boeing 757. Only two operators fly it on such long-haul routes – United Airlines and Icelandair.

Robin Guess / ShutterstockThis United Airlines route between Newark and Stockholm is a venerable connection with two decades of heritage. Apart from a predictable pandemic hiatus, United has operated it consistently since 2005, always with the Boeing 757-200. It competes on the route with Delta, which flies from JFK with A Boeing 767. 

Ultimately, the 757 will be relieved of duty, gradually phased out starting this year to be replaced by the incoming Airbus A321XLR. Whether this super long route will see the shiny new aircraft soon remains to be seen, but by the end of the decade, all United’s 757s will be phased out.

5: SAS Scandinavian Airlines: Copenhagen – Toronto

3,383 NM / 3,893 miles / 6,265 km

Flightradar24RouteBNA – DUBFlight numberSK949Block time8 hours 40 minsAircraftAirbus A321LRFlights in S25414After some turbulent years, SAS has emerged as a reorganized airline with a new airline alliance. After it joined SkyTeam in September 2024, it launched a flurry of SkyTeam-focused routes. In the US, Atlanta came first and Seattle has been scheduled for May, although it will use its widebody A350 and A330 for that.

AirbusNotably, SAS dropped its longest narrowbody flights between Stockholm and Toronto – over 3,400 NM – which freed up some A321LR capacity. That capacity has been added to the Copenhagen – Toronto route, which will operate daily all summer with 414 scheduled flights. 

The route from Copenhagen to Toronto is the same distance as number six on our list, Aer Lingus’ forthcoming Nashville service. But SAS blocks the time for this journey at eight hours 40 minutes, according to OAG data, so it joins United in being one of the three longest narrowbody flights by time this summer.

6: Aer Lingus: Nashville – Dublin

3,383 NM / 3,893 miles / 6,265 km

FreeMapToolsRouteBNA – DUBFlight numberEI76Block time8 hours 5 minsAircraftAirbus A321XLRFlights in S25226Nashville is getting a lot of European love in summer 2025. From just one daily flight by British Airways to Heathrow (LHR) at present, April will see two new long-haul narrowbody routes added. 

Originally planned to launch in May, Icelandair has accelerated the launch of its route from Reykjavik (KEF) to Nashville (BNA), and will now begin service on April 10, 2025. But at 2,808 NM, that route’s not nearly long enough to make the top 10.

Probably one of the most exciting route launches coming this summer, Aer Lingus will follow Icelandair with a Nashville service from Dublin (DUB), starting April 12, 2025. At 3,383 NM, it’s the same distance as the SAS service, but it’s quicker at eight hours and five minutes. 

It’s the first time Dublin has had a connection to Music City. Appropriately for the brand new route, Aer Lingus is using a brand new aircraft – its Airbus A321XLR. The trip is more than within the 4,700 NM range of the XLR, which will operate four times a week through the summer.

Aer LingusStarting May 3, 2025, Aer Lingus will launch its second A321XLR route from Dublin to Indianapolis (IND). At 3,220 NM, it’s the 18th longest narrowbody flight this summer, but not as long as its A321LR service to Minneapolis (MSP). 

7: Air Transat: Lima – Toronto

3,344 NM / 3,848 miles / 6,193 km

Flightradar24RouteLIM-YYZFlight numberTS153Block time7 hours 55 minsAircraftAirbus A321LRFlights in S25121The second of three Transat routes in the top 10 longest narrowbody flights also connects to Lima in Peru, but this time from Air Transat’s focus city at Toronto Pearson (YYZ). Covering 3,344 nautical miles, it’s the seventh longest narrowbody flight in the summer schedule right now.

Onboard, passengers have a choice of economy or ‘Club Class,’ which is unusual for a low-cost airline. While Club doesn’t have the lie flat seats of a widebody aircraft, it offers a solid premium economy-level product for a bit more comfort on the flight. In economy, legroom is about average, although the aircraft does have individual touchscreens. 

For these longer flights, Transat throws in a meal service with alcohol, free non-alcoholic beverages and a snack before landing. It also has reclining seats and allows a piece of carry-on baggage without charging, all of which is quite unusual for a budget airline, and yet still at very competitive fares.

8: Iberia: Washington – Madrid

3,306 NM / 3,804 miles / 6,122 km

FreeMapToolsRouteIAD – MADFlight numberIB362Block time7 hours 50 minsAircraftAirbus A321XLRFlights in S25342The operator of the world’s first Airbus A321XLR, Iberia, will operate the world’s eighth longest narrowbody flight this summer when it takes its shiny new jet to Washington. Iberia had originally scheduled the Washington to Madrid route to begin in January. However, it pushed this date back and will now commence the service on April 12, 2025. 

Iberia’s A321XLR has 182 seats with both business and economy class. In light of the long routes these aircraft will fly, it features the Airspace cabin by Airbus with customizable LED lighting, larger overhead bins and more width. This translates into 18-inch wide economy seats – just an inch wider than most widebodies, but an inch you’ll certainly notice on this eight hour trek.

The business class features fully flat seats on par with Iberia’s widebody fleet, configured for direct aisle access. But the airline didn’t forget that 90% of its passengers fly at the back, and have equipped the aircraft with Recaro’s top of the line R3 seat, which offers ergonomic comfort, an adjustable headrest and a little recline.

9: Air Transat: Nice – Montreal

3,306 NM / 3,804 miles / 6,122 km

#image_titleRouteNCE-YULFlight numberTS629Block time8 hours 40 minsAircraftAirbus A321LRFlights in S25116Air Transat pops up again as the operator of the ninth longest narrowbody flight in summer 2025, and the third flight in the top ten list that has a block time of eight hours and 40 minutes. This time, it’s not South America, though. It’s one of Transat’s many European services, operated seasonally during the summer peak.

For some of its European routes, Air Transat breaks out the big guns and uses its widebody Airbus A330s. But where it makes sense, the A321LR still shines, as is such on this 3,300 nautical mile route between Montreal and Nice. 

Although Air Transat operates three of the top 10 longest narrowbody flights, it operates a whole load of other very long flights with its A321LRs. Just outside of the top 10 are Toronto to Paris (CDG), Montreal to Marseilles (MRS), and Toronto to Amsterdam (AMS).

10: GOL Linhas Aereas: Brasilia – Orlando

Brazilian airline GOL has held the accolade of running the longest Boeing 737 MAX route since it began service to Orlando from Brasilia in 2018. It leaves the Brazilian capital at 09:40 and arrives in Florida at just after 16:00, flying for eight hours and 25 minutes.

Nathan Coats / WikimediaThe Boeing 737 MAX has an impressive range across all variants, but the MAX 8 is the one that can fly the furthest. Its 3,500 nautical mile range is being put to good use by airlines other than GOL. 

Just missing out on the top 10 longest narrowbody flights list is Arajet, with its 3,252 nautical mile 737 MAX service from Ezeiza in Buenos Aires to Punta Cana in the Dominican Republic.

GOL runs some other long flights with the MAX, notably Brasilia to Miami (3,134 NM) and to Cancun (3,187 NM). Icelandair’s 3,000 NM-plus Boeing 737 MAX flights include Keflavik (KEF) to Vancouver (YVR) and Orlando (MCO).
