Average Flight Speed (2026 Data)

A passenger jet at cruising height flies at a large fraction of the speed of sound, yet the typical US flight averages far less than that. Counting the whole time in the air, climb and descent included, US domestic passenger flights averaged 423.9 mph¹ (682.2 km/h²) in 2025 across 8,402,870¹ departures. At cruise, the Boeing 787-8 flies at Mach 0.85³, about 564 mph² at 35,000 feet.³ The gap between those two numbers explains most of what follows: short hops spend much of their time climbing and descending, while long flights spend hours at cruise height and ride, or fight, the jet stream.

Speed decides how long a trip takes, how many flights an aircraft can fly in a day and why the same route can be 40 minutes shorter one way than the other. The sections below show how fast planes fly by distance, aircraft type, airline, airport and state, how speed has changed since 1990, why flying east from Los Angeles to New York was 62 mph² faster than flying west in 2025, and the federal rule that caps airliners at 288 mph² below 10,000 feet.

How fast planes fly today

US domestic passenger flights averaged 423.9 mph¹ in the air in 2025, or 682.2 km/h². That is the great-circle distance between the two airports divided by the time from takeoff to landing, averaged over 8,402,870¹ scheduled and charter passenger departures; all-cargo flights, helicopters and a small number of impossible or mis-filed records are left out. The average flight covered 756.8 miles¹ (1,217.9 km²) and spent 107.1 minutes¹ in the air.

The figure is lower than the speed a pilot reads at cruise, because every minute of climb and descent is in it. A flight's air time runs from wheels-up to touchdown, and the first and last half hour or so is flown well below cruise speed, partly because of the federal speed limit near the ground described further down.⁴ Individual flights spread widely around the average. About 30.4%¹ of 2025 departures averaged 400 to 449 mph in the air, 26.4%¹ stayed under 350 mph and 21.1%² reached 450 mph or more; only 6.0%¹ passed 500 mph.¹

Airborne speed vs gate-to-gate speed

The average block speed of a commercial flight in the US was 340.8 mph¹ (548.5 km/h²) in 2025. Block time runs from the moment the aircraft leaves the gate to the moment it parks at the other end, so it adds taxiing, the queue for the runway and the wait for a free gate to the time in the air. The average block time was 133.2 minutes¹, which leaves 26.1 minutes¹ per flight on the ground, and the block speed is 83.1 mph² below the airborne speed. Block speed is the number that decides how long the trip feels from the seat; airborne speed is the one that describes the airplane in flight.

What the numbers cover

Every speed on this page is the average domestic flight speed within the United States, including flights to and from Hawaii, Alaska and the US territories, flown by US and foreign airlines that report their domestic segments. International flights are not included. No official table reports true airspeed for each flight, so the speeds are distance divided by time: a clean measure of how fast passengers actually travel, not a reading from the cockpit.¹

Has flight speed changed since 1990?

Only a little. In July 1990 the average domestic flight flew at 416.5 mph¹ in the air; in July 2025 it flew at 427.2 mph¹, and the highest July value was 430.4 mph¹, in 2023.¹ The long series uses one month per year, July, and it has a break. In July 2003 several regional airlines appear in the data for the first time: July departures jump 22.6%², from 673,826¹ in 2002 to 825,894¹ in 2003, and SkyWest alone adds 33,127¹ short flights at 325.4 mph¹.¹ The fall to 398.7 mph¹ in July 2003 comes from that change in who reports, not from slower airplanes, so values before and after 2003 cover different sets of airlines. The all-airline trend lines below are fitted from 2003 for that reason.

Extended in a straight line, the 2003-2025 trend reaches about 464.2 mph² by 2050. That is our calculation, not a forecast, and it stays well below cruise speed: the rise comes from longer routes, not faster airplanes.

The same airlines, 1990 to 2025

A cleaner test follows only the airlines that reported every July from 1990 to 2025: American, Alaska Airlines, Delta, Horizon Air, United and Southwest. Their flights averaged 429.7 mph¹ in the air in July 1990 and 447.7 mph¹ in July 2025, a gain of 18.0 mph². Their line shows no break in 2003 (441.5 mph¹ in 2002, 442.8 mph¹ in 2003), and over the same years their average July flight grew from 654.7 miles¹ to 962.8 miles¹, 47.1%² longer.¹

Airplanes did not get much faster in those 35 years. What changed is how far they fly: across all reporting airlines the average July flight grew from 594.4 miles¹ in 1990 to 762.2 miles¹ in 2025, 28.2%² longer. Longer flights spend a larger share of their time at cruise height, which lifts the average speed without any change in the airplanes.

Gate-to-gate speed over time

Block speed moved even less. It was 339.1 mph¹ in July 1990 and 342.2 mph¹ in July 2025. Its highest point came in July 2020, at 353.0 mph¹, when the pandemic emptied taxiways and gates and flights lost less time on the ground.¹

Time on the ground is why. The average July flight spent 19.5 minutes¹ between gate and runway in 1990 and 26.6 minutes¹ in 2025, the most in the series. The rise was not steady: the series dipped in several years, its lowest July was 1995 at 18.1 minutes¹, and its sharpest fall came in 2020, to 19.3 minutes¹, after which it climbed every year.¹ With seven more minutes on the ground per flight, block speed rose only 3.1 mph² between July 1990 and July 2025, against 10.7 mph² in the air.

The distance line explains the rest. The average July flight grew by 167.8 miles² between 1990 and 2025, with a dip in 2020, and a straight-line extension of the 2003-2025 trend reaches about 987 miles² by 2050, again our calculation, not a forecast.

Full years tell the same story

Full-year averages run a few miles an hour below the July values, but the direction is the same: 410.2 mph¹ in 1990 and 423.9 mph¹ in 2025. Full-year block speed stayed between 328.6 mph¹ (2005) and 347.1 mph¹ (2020) in the nine years checked, and ground time rose from 18.9 minutes¹ in 1990 to 26.1 minutes¹ in 2025.¹

From decades to distance: the next sections look at what makes one flight faster than another.

Why longer flights are faster

Flights under 500 miles averaged 323.8 mph¹ in the air in 2025. Flights of 1,000 to 1,499 miles averaged 449.3 mph¹, and flights of 1,500 to 1,999 miles 470.8 mph¹. The fastest band was 3,500 to 3,999 miles, at 528.4 mph¹, and the few flights of 5,000 miles or more, all of them between the mainland and Hawaii, averaged 517.8 mph¹, 194.0 mph² faster than the shortest band.¹

The reason is simple arithmetic. Every flight climbs and descends at low speed, and that part takes about the same time on a short hop as on a long haul. On a 270-mile flight it is most of the trip; on a 5,095-mile flight it is a small slice. Above about 3,500 miles the average levels off between 517.4 mph¹ and 528.4 mph¹, and the wind decides the rest.

Where the extra time goes: taxi, climb and descent

Ground time barely changes with distance. The shortest flights spent 24.2 minutes¹ between gate and runway at the two ends of the trip, and the longest 33.1 minutes¹.¹ Because that ground time stays almost fixed, its share of the trip shrinks as flights get longer: time in the air was 67.4%¹ of gate-to-gate time on flights under 500 miles and 94.7%¹ on flights of 5,000 miles or more.

Average flight speed by aircraft type

The most common airliner in US domestic service in 2025 was the Embraer 175 regional jet, with 1,155,217¹ departures at an average 385.0 mph¹.⁵ The Boeing 737-800 flew 983,257¹ times at 438.6 mph¹, and the Airbus A321 506,039¹ times at 451.4 mph¹. Among the 39² named types with at least 10,000 departures, the gap between them follows the routes they fly more than the airplanes themselves: regional jets fly short hops of about 440 to 520 miles, while the Airbus A321neo averages 1,484.8 miles¹ and 465.8 mph¹.¹

Same route, different airplanes

On one route the type matters much less. Between New York JFK and Los Angeles, four types flew at least 1,000 times each way in 2025. In the same direction their average airborne speeds were no more than 13.0 mph² apart, while each type flew 57.5² to 70.8 mph² faster eastbound than westbound.¹

Average flight speed of a 737

The 737 family flies more US domestic departures than any other airliner family, about 2.89 million² in 2025, and its speed depends on the model and its routes. The 737-800 averaged 438.6 mph¹ over 908.9 miles¹, the 737 MAX 8 447.3 mph¹ and the 737-900ER 449.5 mph¹. The smaller 737-700 group, which flies shorter routes of 680.3 miles¹, averaged 421.1 mph¹, while the 737 MAX 9, at 1,464.3 miles¹ a flight, averaged 464.9 mph¹.¹

The average flight speed of a Boeing 777

Among types with at least 10,000 US domestic flights, the Boeing 777-200 was the fastest in 2025 at 508.1 mph¹, on long routes: 2,242.1 miles¹ on average, the third-longest in the table, with about 40%² of its flights to or from Hawaii. The Airbus A330-200, which flies the longest routes, averaged 500.2 mph¹ over 2,673.9 miles¹.¹ The 777-200's listed cruising speed is 615 mph³; the measured average is 106.9 mph² lower, partly because climb and descent are in it.³

Cessna average flight speed

Small propeller aircraft still fly scheduled passenger routes, mostly short island and bush hops. Cessna aircraft made 372,121¹ passenger departures in 2025 over an average of just 81.6 miles¹, at 143.6 mph¹ in the air. The single-engine Cessna 208 Caravan, the most common of them, averaged 140.2 mph¹ on routes of 85.6 miles¹.¹

Average flight speed by aircraft size

Bigger airplanes are faster on average, again because they fly farther. Aircraft with fewer than 80 seats averaged 356.5 mph¹ on flights of 393.0 miles¹, while aircraft with 200 or more seats averaged 467.5 mph¹ on flights of 1,406.7 miles¹, a gap of 111.0 mph². The 150-199 seat group, the single-aisle Boeing and Airbus jets, flew the most departures of any size band, 3,616,653¹, at 447.3 mph¹.¹

Does the jet stream change flight speed?

Yes, and by more than the choice of airplane. The jet stream blows from west to east across the United States at cruise height, so eastbound flights get a tailwind and westbound flights a headwind. The average commercial jet speed on a long-haul flight from Los Angeles to New York JFK was 514.7 mph¹ in 2025; the same route westbound averaged 452.3 mph¹, a 62.4 mph² difference, and the westbound flight spent 39.8 minutes² longer in the air.¹

The pattern holds on all four coast-to-coast pairs checked. San Francisco to Newark averaged 538.6 mph¹ against 460.0 mph¹ the other way, 78.6 mph² apart and 48.9 minutes² longer westbound. San Francisco to New York JFK averaged 520.5 mph¹ against 445.3 mph¹, and Los Angeles to Boston beat Boston to Los Angeles by 74.7 mph². Even the 740-mile Chicago-New York route shows it: 431.0 mph¹ eastbound against 362.7 mph¹ westbound.¹

Same airports and, as the route table above shows, the same airplanes: a difference of more than 60 mph comes from the direction of the wind.

Fastest and slowest flights

Among routes of at least 1,000 miles with at least 500 flights, the fastest in 2025 was Honolulu to Dallas/Fort Worth at 565.1 mph¹, followed by Honolulu to New York JFK at 552.9 mph¹ and Honolulu to Denver at 551.5 mph¹.¹ All three fly eastbound, the same direction as the faster coast-to-coast flights above. The slowest scheduled airplane routes are short bush and island hops.¹ The 4-mile¹ Alaska hop from Nunapitchuk to Kasigluk averaged 46.6 mph¹ and the return 48.3 mph¹, with about 5 minutes¹ in the air per flight, and the 14-mile¹ hop from Friday Harbor to Eastsound in Washington's San Juan Islands averaged 56.2 mph¹.¹ One island pair is left out of the list: on the 17 miles between Vieques and Culebra in Puerto Rico, one airline reported about 30 minutes¹ in the air per flight and another about 6.6 minutes¹, so the first airline's records are treated as a filing error.¹

Average flight speed by month

The season changes flight speed only slightly. The 2025 monthly average ranged from 418.1 mph¹ in March to 428.0 mph¹ in September, a spread of 9.9 mph². June to October averaged at least 426.4 mph¹, while January to March stayed below 421 mph¹.¹ A spread that small means the season barely changes how long a flight takes.

Average flight speed by airline

Among the 15 airlines with the most US domestic departures, Alaska Airlines had the highest average airborne speed in 2025, 461.0 mph¹, on flights of 1,370.1 miles¹. United followed at 451.5 mph¹. Regional airlines that fly short feeder routes for the big carriers were slowest: Piedmont averaged 325.6 mph¹ on flights of 283.1 miles¹.¹ The 135.4 mph² gap says mostly where each airline flies, not how fast its airplanes can go.

Average flight speed at the busiest US airports

Flights leaving San Francisco and Los Angeles were the fastest among the 15 busiest US airports in 2025, at 483.7 mph¹ and 483.2 mph¹, because so many of them head across the country or to Hawaii. Flights from New York LaGuardia were the slowest of the 15 at 391.6 mph¹, on routes that average 752.0 miles¹, far shorter than the West Coast airports' long flights.¹ Boston, at 398.6 mph¹, shows that distance is not the whole story: its average route of 940.5 miles¹ is about as long as Orlando's, and its longest flights head west into the headwind, such as Boston to Los Angeles at 452.7 mph¹.

Ground time at the busiest airports

Time on the ground differs more between airports than between distance bands. Flights leaving New York LaGuardia spent 35.6 minutes¹ of their gate-to-gate time on the ground, Chicago O'Hare 33.3 minutes¹, while flights from Phoenix spent 23.3 minutes¹.¹ The figure counts taxiing at both ends of the trip, so it also reflects the airports these flights arrive at.

Average flight speed by state

Flights leaving Hawaii were the fastest of any state in 2025, averaging 477.8 mph¹, because nearly every flight out of the islands to the mainland is a long ocean crossing. Nevada (463.5 mph¹), California (463.1 mph¹) and Washington (460.6 mph¹) came next.¹ Alaska was the slowest state at 271.1 mph¹, 206.7 mph² below Hawaii: its average departure covers only 208.6 miles¹, and many are short bush flights between villages. Small Northeastern states such as New Hampshire (339.3 mph¹) and Vermont (350.7 mph¹) also sit low, with mostly short flights to nearby hubs.

The ranking below lists the ten fastest and ten slowest states, with the number of departures and the average distance behind each figure.¹

From where planes fly to how fast they are allowed to fly.

What limits how fast a commercial plane can fly

Near the ground, the law does. Below 10,000 feet, no aircraft in US airspace may fly faster than 250 knots⁴, about 288 mph². Within 4 nautical miles of a mid-size or smaller towered airport, at or below 2,500 feet, the cap is 200 knots⁴, or 230 mph², and the same 200-knot limit applies under the edges of the airspace around the biggest airports.⁴ Every flight therefore spends its first and last minutes at about half its cruise speed or less, which is why short flights average so little.

Higher up, the airplane's certification sets the limit. The Airbus A320neo, for example, may not exceed 350 knots⁶ (403 mph²) indicated airspeed or Mach 0.82⁶, 82% of the local speed of sound.⁶ These are maximums, not the speed airlines fly day to day. For the speed they do fly, the manufacturer's own figures are the reference: the Boeing 787-8 is listed at a cruising speed of Mach 0.85³, the 757-200 at 500 mph³ and the 777-200 at 615 mph³.³ At 35,000 feet, where the speed of sound in the standard atmosphere is about 663.3 mph², Mach 0.85 works out to about 563.8 mph² true airspeed, still 99.5 mph² short of the sound barrier. Airliners stay below it because drag rises sharply as they approach it, and fuel burn with it.

The limits that hold every airliner below those speeds near the ground, and one certificated maximum, are summed up below.⁴

Flight speed compared with other kinds of travel

The average speed of a commercial flight vs. car travel is not a like-for-like pair, because only the flight has a measured average. Gate to gate, a US domestic flight averaged 340.8 mph¹ in 2025. The most common top speed limit on rural interstates is 70 mph⁷, so the flight covers ground about 4.9² times faster than a car driving at the legal maximum, before the drive to the airport and security are counted.⁷ The Acela train averages about 68 mph⁸ over the 457-mile⁸ Boston-Washington corridor and reaches its top speed of 150 mph⁸ only on a stretch of 18 miles⁸; the flight's block speed is about 5.0² times the train's average.

History sets the upper bound. Concorde, retired in 2003⁹, cruised at about twice the speed of sound at 55,000 to 60,000 feet, and its top speed was 1,350 mph⁹ (2,179 km/h⁹).⁹ Today's average domestic flight covers less than a third of that top speed in the air.

What flight speed means for your trip

For a traveler, the useful number is the gate-to-gate one. A 757-mile flight, the 2025 average, took 133.2 minutes¹ from gate to gate, of which 26.1 minutes¹ were spent on the ground. On a short flight that ground time is a third of the trip: on routes under 500 miles only 67.4%¹ of the gate-to-gate time was in the air.¹ That is why a one-hour hop rarely saves as much time over driving as its airborne speed suggests.

On long routes, direction matters more than aircraft. Flying west from New York to Los Angeles took 39.8 minutes² longer in the air than the eastbound trip in 2025, and from Boston to Los Angeles the westbound penalty was 49.1 minutes².¹ On a round trip across the country, the way back west is the longer leg.

Conclusions

1. The 424 mph average is a whole-flight number, not a cruise speed. Climb, descent and low-altitude speed limits pull the 2025 airborne average of 423.9 mph well below the Mach 0.85, about 564 mph, listed for the Boeing 787-8 at cruise.^{1 3}
2. Distance, not the airplane, sets a flight's average speed. Flights under 500 miles averaged 323.8 mph and flights of 5,000 miles or more 517.8 mph; the same pattern ranks airlines, airports, states and seat sizes.¹
3. Wind matters more than aircraft type. On the Los Angeles-New York JFK route, each of the four main types flew 57.5 to 70.8 mph faster eastbound, while the types differed by no more than 13.0 mph in the same direction.¹
4. Flights got longer, not much faster. The six airlines that reported every July since 1990 flew 47.1% longer flights in 2025 at 18.0 mph more in the air, and across all airlines ground time grew from 19.5 to 26.6 minutes, so gate-to-gate speed barely moved.¹
