Studying the flight times here on Flightaware dot com, I’m curious to know what factors are involved and who actually sets the flight plan say between Manchester UK and Orlando Florida USA? ie VS075.
The flight times seem to vary up to fifty minutes. Are there any pressures to select the route that uses the least fuel, or are there any rules that say the flight must arrive between certain times? I understand the flight path can change according to the weather as well but are there any rules to say how much turbulence is acceptable?
A curious passenger.
