A modern Boeing 747 can fly about 15,000 km (9,500 miles) when it's flying at 900 kmh (550 mph). This means it can fly non stop for almost 16 hours!

A plane like a Boeing 747 uses approximately 1 gallon (about 4 liters) of fuel every second. Over the course of a 10-hour flight, it might burn 36,000 gallons (150,000 liters). The 747 burns approximately 5 gallons of fuel per mile (12 liters of fuel per kilometer).
A typical takeoff speed for a Boeing 747 is around 160 knots (184 mph), depending on the jet's wing flap configuration, the number of passengers aboard, and the weight of their luggage, fuel load, current weather conditions, and other factors.
A Boeing 747 can endure about 35,000 pressurization cycles and flights—roughly 135,000 to 165,000 flight hours—before metal fatigue sets in. 747s are retired after approximately 27 years of service.
Air traffic represents less than 2-3% of the global CO2 emissions whereas road traffic accounts for around 10% of these direct emissions. Still, planes remain among the most polluting means of transport, together with cars.
Jet Fuel Cost by Aircraft Cabin SizeFor example, on May 11, 2022, the IATA per gallon price was $4.82 in North America, $4.01 in Europe, and $3.55 in Asia. At Boston's Hanscomb Field Jet A was selling between $9.79 and $13.38 per gallon.
Next time you board a flight, just imagine you're putting a $20 bill in the airline's tip jar. Profit per passenger at the seven largest U.S. airlines averaged $19.65 over the past four years—record-setting profitable years for airlines. In 2017, it stood at $17.75, based on airline earnings reports.
The process to install an interior can take up to two years. Operating a BBJ 747-8 will cost an estimated $23,000 an hour – but if you can afford to buy a your own 747, this cost is inconsequential.
While it's very clear that a 747 cannot fly properly with the failure of three engines, we can see that a single functioning engine would at least extend the aircraft's distance and prolong its time in the air.
What is the longest flight in the world by distance? The longest flight in the world by distance is New York (JFK) to Singapore (SIN) on Singapore Airlines clocking in at 9,537 miles. What plane can fly the farthest in the world?
The good news is that pilots are supposed to dump fuel at a safe height above the ground and away from other aircraft, and in addition, over as remote an area as possible. In the case of Heathrow, for example, most fuel dumps have occurred over the sea.
While fuel dumps don't happen every day, they're also not uncommon. Nor do they usually represent a major emergency. In fact if an aircraft is taking the time to dump fuel before landing, that's likely an indication that the issue forcing the plane to land is serious but not critical.
Aviation is responsible for between 2pc and 3pc of global carbon emissions. And Ms Thunberg continues to refuse to fly because of the impact on the environment.
Built in 1967 to produce the mammoth jet, it remains the world's largest manufacturing plant according to Boeing. But after five decades, customer demand for the 747 eroded as Boeing and Airbus (AIR.PA) developed more fuel efficient two-engine widebody planes.
As long as you follow the proper regulations for private jets, there is no reason why you couldn't buy and fly a 747. The oldest 747-8 is only ~8 years old. It's not that second hand ones aren't occasionally offered up for sale, but if you're restricting yourself to the -8, don't expect a lot of great deals.
