Fuel efficiency is the most important, if not the latest, buzzword in aviation. Fuel remains one of the leading operating cost heads for an airline, and thus controlling fuel costs can lead to significant bottom line improvements.
This is the age of fuel efficient aircraft. The 787s and A350s of the world are setting benchmarks in terms of being less fuel dependent while not compromising on the flight experience.

But how exactly does the fuel consumption figures of the 787 compare to a 777? Or an A380? The below table provides the numbers for you!
Note: The below numbers are indicative. Fuel consumption numbers depend upon a lot of factors including flight takeoff weight, flight time, cruising altitude and the like. Read the numbers as ballpark figures.
| Manufacturer | Aircraft | Fuel Consumption (kilogram/hour) |
| Boeing | 707-320 | 6800-7200 |
| Boeing | 707-420 | 6400 |
| Boeing | 707-320B | 5500 |

| Airbus | A300 | 4770 |
| Airbus | A319-100 | 2374 |
| Airbus | A320 | 2430 |
| Airbus | A321-100 | 2885 |
| Airbus | A321-231 | 2740 |

| Airbus | A340-300 | 6500 |
| Airbus | A340-500 | 8000 |
| Airbus | A350-900 | 5800 |
| Airbus | A380 | 11000-12000 |
| Аn-225 | 15900 | |
| Аn-124 | 12600 | |
| Bombardier Dash 8 | 900 | |
| ATR 42 | 450 | |
| ATR 72 | 620 |
As we see, an Airbus A380 burns twice as much fuel per hour as a Boeing 787-9. A head-to-head comparison between the two aircraft can give airlines millions of dollars in savings just by choosing a 787-9 over the A380 (though an A380 has almost double the number of seats compared to the 787).
