Commercial jets can fly as much as 16,600 kilometers without refueling. That is, about a 19 hour long flight.
Somewhere around 1600-1700 nautical miles, which is 1.800-2.000 miles, which is 3.000-3.200 kilometers.
you use a helicopter jet pack
I would say the engine turbines, because that's what powers the jet and without it the plane wont fly long or even fly at all!
jet plane did not go to moon
you can do so as long as you have all your legal documents
Man is too dense to fly without assistance. Some have gotten limited flight with a jet pack.

at least 18 hours
Easy to answer, 14 hours and 45 minutes with actuary based passenger weight data and baggage weight distribution loads over the three tier class travel sytem, but the distance it can travel depends is not predictable die to variations in weather, jet stream, cornialis effect, (East or Westerly direction) but is in the range of 7000 NM
30 seconds or so, to fill up a jet fighter from a refueling tanker plane in mid air at 400mph!
Jet planes fly with the help of Thrust and Lift produced by the jet engines.
