The 10 longest flights you can book in 2027
In October 2027, the Kangaroo Route finally loses its last stop. Qantas flight numbers QF1 and QF2 are scheduled to fly Sydney–London nonstop for the first time, on a specially built Airbus A350-1000ULR. The great-circle distance is 17,016 kilometres (10,573 miles). Qantas says the aircraft can stay in the air for up to 22 hours. Tickets are due to go on sale in February 2027.
Until that first departure, Singapore Airlines’ daily Singapore–New York-JFK service remains the longest flight you can board today, at 15,341 kilometres and 19 hours 15 minutes westbound.
This list ranks the 10 longest nonstop passenger flights you can actually book in 2027, with the airline, the aircraft, the distance, the scheduled time and the fine print that usually gets left out.
How this list was ranked
Entries are ranked by great-circle distance, not block time, because winds can make a shorter route take longer than a longer one. “Bookable in 2027” is taken literally: Qantas’s Sydney–New York service does not fly until mid-2028, but seats go on sale in August 2027. Seasonal routes in early-2027 schedules are included, with a note. Codeshares, cargo and charters are out.
Current routes (entries 3–10) use aircraft, block times and frequencies from Passrider.com’s 5 September 2026 extract of airline schedules, with seasonal routes checked against December 2026 and February 2027. Sydney–London and Sydney–New York distances were calculated on the WGS84 ellipsoid and match Great Circle Mapper. The same check on the eight published routes agreed within 17 kilometres. Schedules change — confirm the routing for your date.
The 10 longest bookable flights
1. Sydney (SYD) – London Heathrow (LHR) — 17,016 km Qantas QF1/QF2 · Airbus A350-1000ULR · 17,016 km / 10,573 mi / 9,188 nmi · up to 22 hours* · daily · operates from October 2027 · on sale February 2027.
This is Project Sunrise. The A350-1000ULR carries an extra 20,000-litre fuel tank and 238 seats across four cabins, with a Wellbeing Zone open to every passenger. The existing service via Singapore continues as QF5/QF6. Exact block times have not been published; “up to 22 hours” is Qantas’s endurance language, not a filed schedule.
2. Sydney (SYD) – New York-JFK (JFK) — 16,013 km Qantas · Airbus A350-1000ULR · 16,013 km / 9,950 mi / 8,646 nmi · around 18 hours, Sydney to New York* · frequency not yet published · operates from mid-2028 · on sale August 2027.
The second Sunrise route, and the first nonstop commercial service between New York and Australia’s east coast. Qantas says it will cut more than three hours off today’s fastest one-stop journey. You cannot fly it in 2027, but you can start booking it in 2027.
3. Singapore (SIN) – New York-JFK (JFK) — 15,341 km Singapore Airlines SQ23/SQ24 · Airbus A350-900ULR · 15,341 km / 9,532 mi · 19h 15m JFK–SIN / 18h 40m SIN–JFK · daily.
The current longest scheduled passenger flight in the world, by distance and by time, and the title-holder since 2021. The ULR is a two-cabin aircraft — business and premium economy, no economy cabin — built for a sector with very little spare range. It remains the longest flight you can take today.
4. Singapore (SIN) – Newark (EWR) — 15,337 km Singapore Airlines SQ21/SQ22 · Airbus A350-900ULR · 15,337 km / 9,530 mi · 19h 10m EWR–SIN / 18h 25m SIN–EWR · daily.
Four miles shorter than its JFK sister, on the same aircraft, with a westbound schedule only five minutes behind.
5. Perth (PER) – London Heathrow (LHR) — 14,508 km Qantas QF9/QF10 · Boeing 787-9 · 14,508 km / 9,015 mi · 17h 50m PER–LHR / 16h 50m LHR–PER · daily.
The original Australian nonstop to Britain, launched in 2018. Westbound QF9 has been making a Singapore fuel stop after airspace reroutes ate into the 787-9’s margin. It is scheduled to return to nonstop flying on 1 February 2027. Eastbound QF10 has remained nonstop. Confirm the routing before you buy.
6. Dallas/Fort Worth (DFW) – Melbourne (MEL) — 14,475 km Qantas QF21/QF22 · Boeing 787-9 · 14,475 km / 8,995 mi · 17h 40m DFW–MEL / 16h 10m MEL–DFW · three times weekly.
A 90-minute gap between the two directions shows what the jet stream does on this sector.
7. Perth (PER) – Paris Charles de Gaulle (CDG) — 14,273 km Qantas QF33/QF34 · Boeing 787-9 · 14,273 km / 8,869 mi · 17h 30m PER–CDG / 16h 40m CDG–PER · three times weekly, seasonal.
Not in the September 2026 schedule; it does appear in the December 2026 and February 2027 weeks that were checked. Treat it as seasonal, and check your dates.
8. Auckland (AKL) – New York-JFK (JFK) — 14,215 km Qantas QF3/QF4 and Air New Zealand NZ1/NZ2 · Boeing 787-9 on both · 14,215 km / 8,833 mi · 17h 50m JFK–AKL on NZ1; 16h 10m AKL–JFK on NZ2 · daily on Qantas, three times weekly on Air New Zealand.
The only top-10 entry with two airlines flying their own metal on the same city pair. Qantas continues the aircraft on to Sydney.
9. Auckland (AKL) – Dubai (DXB) — 14,201 km Emirates EK448/EK449 · Airbus A380-800 · 14,201 km / 8,824 mi · 17h 05m AKL–DXB / 15h 50m DXB–AKL · daily.
The only A380 in the top 10. When this service launched in 2016 it briefly held the world record.
10. Shenzhen (SZX) – Mexico City (MEX) — 14,130 km China Southern CZ8031 · Airbus A350-900 · 14,130 km / 8,780 mi · 16h 15m SZX–MEX · three times weekly.
The Shenzhen–Mexico City leg is a nonstop. The return is not: the schedule shows the way back running through Tijuana. It is the only one-way nonstop in the top 10. Just off the list: Singapore–Los Angeles, at 14,102 km.
What the distances do not tell you
A great-circle line is the shortest path on the sphere, not always the path the aircraft files, and never the only thing that decides how long you sit down. Westbound trans-Pacific and Europe–Australia sectors are usually slower, because they work against the prevailing winds. Dallas–Melbourne is 17 hours 40 minutes one way and 16 hours 10 minutes the other.
Airspace is the other hidden variable. Perth–London westbound spent part of 2026 stopping in Singapore not because the 787-9 lost range, but because longer reroutes left too little margin. A relatively small detour can turn a nonstop into a fuel stop. Sydney–London goes on sale in February 2027 for travel from October. Sydney–New York goes on sale in August 2027 for travel from mid-2028.
Ten flights, nine countries
Fly every one of these 10 routes and you will land in only nine countries: Australia, China, France, Mexico, New Zealand, Singapore, the United Arab Emirates, the United Kingdom and the United States. Together the 10 great-circle legs add up to 149,509 kilometres — just under 3.7 times the distance around the equator — and they never touch a tenth country.
Ultra-long-haul concentrates on a handful of city pairs. Miles and country counts are different kinds of record. A pin map is a more honest instrument than a mileage balance.

How long will Sydney–London nonstop actually take?
Qantas has said the A350-1000ULR can fly for up to 22 hours, and that the nonstop will cut up to four hours off the current one-stop journey. Exact block times have not been published.
Is Perth–London nonstop again?
Eastbound QF10 has remained nonstop. Westbound QF9 is scheduled to return to nonstop flying on 1 February 2027.
Why do some long flights take longer in one direction?
Prevailing winds, especially the jet streams. Distance stays the same; the clock does not.
Which aircraft fly the longest routes?
Mostly the Airbus A350 and Boeing 787 families. This top 10 also includes one Emirates A380, on Auckland–Dubai.
Will these rankings change?
Yes. Airlines add, drop and retime routes, and airspace restrictions can force a fuel stop. This list is a snapshot based on schedules and announcements available in November 2026.

If you have already sat through one of these sectors — or you are planning to — the interesting part is not the leaderboard. It is seeing the route on a dark pin map, next to the rest of your flights, and watching which countries actually light up. Waymarka is a flight travel log built around that map.
