The Boeing 737 is a widely used aircraft with a range of models, including the 737 Classic and Next-Generation series. The fuel consumption of a Boeing 737 varies depending on the model and flight conditions. For example, the 737-800 burns 850 US gallons (3,200 litres) of jet fuel per hour, while the 737-300 has a fuel flow per engine of 1231 kg/h. The fuel efficiency of a 737 can also be impacted by operational conditions, such as cruising altitude and takeoff. Additionally, innovations in fuel efficiency and winglet design, such as Aviation Partners' Split Scimitar winglets, have contributed to fuel savings for the 737.
| Characteristics | Values |
|---|---|
| Fuel consumption per hour | 746.27 gallons or 850 US gallons (3,200 L) |
| Fuel consumption per minute | 12.44 gallons |
| Fuel flow per engine | 1231 kg/h |
| Fuel consumption per seat | 96 mpg per passenger for a 737-800 with 162 passengers on a 1000 NM trip |
| Fuel economy | 66 pmpg for Southwest Airlines' all-Boeing 737 fleet |
| Fuel savings | 5.5% for Split Scimitar winglets, 3.3% for blended winglets |

Fuel consumption varies by model and flight conditions
The 737 MAX 7 is a shortened variant of the MAX 8, based on the 737-700, with a 1,900 km range and a 7% lower operating cost per seat. The 737 Classic series (-300, -400, -500) and Next-Generation series (-600, -700, -800, -900) feature CFM56 high-bypass turbofan engines, which are 25% more efficient and significantly quieter than previous models.
The 737-800 typically uses 746.27 gallons of fuel per hour, or 12.44 gallons per minute. This can be calculated by dividing the hourly rate by 60, the number of minutes in an hour. Fuel efficiency measures vary depending on the aircraft's operation during different flight phases. For example, a 737 will consume more fuel during takeoff than when cruising at altitude.
Southwest Airlines, which operates an all-Boeing 737 fleet, provides insight into the fuel efficiency of the aircraft. With a passenger mileage of 33.1 billion miles, the airline used 500 million gallons of fuel, resulting in 66 passenger miles per gallon (PMPG).

746.27 gallons of fuel per hour
The Boeing 737 is a commonly used airliner. The fuel consumption of a 737 aircraft depends on the model and flight conditions. For instance, a 737 flying at cruising altitude will have different fuel consumption than one during takeoff.
A general estimate is that a 737 aircraft burns 746.27 gallons of fuel per hour. This equates to approximately 12.44 gallons per minute. To put this into context, a good prop plane can achieve 137 miles per gallon per passenger, while long-distance buses connecting major cities can achieve 228 passenger miles per gallon.
The 737-800, the most common variant of the 737NG (Next Generation) family, burns 850 US gallons (3,200 L) of jet fuel per hour. This model can seat 162 passengers in a two-class layout or 189 passengers in a high-density, one-class layout.
The fuel consumption per distance, rather than per time, for a 737-800 flying at a typical cruise of FL370 with a weight of 65 tons is 1231 kg/h.

12.44 gallons of fuel per minute
The fuel consumption of a Boeing 737 varies depending on the model and flight conditions. A general estimate is that the aircraft burns about 746.27 gallons of fuel per hour, which equates to approximately 12.44 gallons per minute.
To put this into context, consider that a 737-800 with 162 passengers on a 1000 NM trip will achieve 96 mpg per passenger. The fuel efficiency of a 737 can vary widely depending on how the aircraft is operated during different phases of flight. For example, fuel consumption will differ when flying at cruising altitude compared to during takeoff.
The 737-800 is the most common variant of the 737NG (Next Generation) family. It burns 850 US gallons (3,200 L) of jet fuel per hour. This model is used by Ryanair, which serves routes across Europe, the Middle East, and North Africa, with a fleet of over four hundred 737-800 aircraft.
Southwest Airlines operates an all-Boeing 737 fleet. Their passenger miles for a recent quarter were 33.1 billion miles, for which they used 500 million gallons of fuel. This equates to 66 passenger miles per gallon (pmpg) of fuel.
The fuel consumption of a 737 can be calculated in various ways, including gallons per minute, miles per gallon, and kg/h.

737-800 burns 850 US gallons of jet fuel per hour
The fuel consumption of a Boeing 737 varies depending on the model and flight conditions. The 737-800, a stretched version of the 737-700, is the most widely used narrow-body aircraft. It burns 850 US gallons (3,200 litres) of jet fuel per hour. This equates to 12.44 gallons per minute.
The 737-800 is the most common variant of the 737NG (Next Generation) family. It seats 162 passengers in a two-class layout or 189 passengers in a high-density, one-class layout. The 737-800 replaced the -400 and ageing 727-200 of US airlines. It also filled the gap left by Boeing's decision to discontinue the MD-80 and MD-90 aircraft following its merger with McDonnell Douglas.
The 737 Classic series (-300, -400, -500) and Next-Generation series (-600, -700, -800, -900) feature CFM56 high-bypass turbofan engines. These engines are 25% more efficient and significantly quieter than the JT8D low-bypass engines used on the 737 Original series (-100 and -200). The improved, higher pressure ratio CFM56-7 turbofan engine on the 737 Next Generation is 7% more fuel-efficient than its predecessor.
In 2011, a 737-800 operated by United Airlines became the first US commercial flight to be powered by a blend of algae-derived biofuel and traditional jet fuel, reducing its carbon footprint.

737-800 fuel economy: 96 mpg per passenger
The 737-800 is the most common variant of the 737NG (Next Generation) family. It burns 850 US gallons (3,200 litres) of jet fuel per hour.
The fuel efficiency of the 737-800 depends on several factors, including the number of passengers, load factors, distance, and route. For example, a 737-800 with 162 passengers on a 1000 NM trip has a fuel economy of 96 mpg per passenger, while the same aircraft with 189 passengers would have a lower fuel economy per passenger.
The 737-800 benefits the most from the addition of winglets among large commercial jets, with an average efficiency increase of 6.69%. However, the actual fuel savings can vary from 4.6% to 10.5% depending on the route.
Other factors that can impact fuel efficiency include continuous descent approaches, single-engine taxiing, and direct routing. For example, flying 600 km below the optimum altitude can result in 600 kg more fuel consumption.
It is worth noting that turboprop airliners tend to have better fuel efficiency than jet airliners, and new technologies and improvements in engine efficiency have led to significant reductions in fuel consumption and emissions over time.
