... Some Flights Take Less Time To Fly In One Direction?

I have just been to Thailand, and it felt like the trip home was much slower than the trip there. Is that true?

If the pilot succeeds in catching one of the so- called jet streams, which mainly move from the west to the east, the plane can have a tailwind on part of the trip from Scandinavia to Bangkok. It only works one way, though. When the plane goes back home, the pilot should do his best to stay away from the jet stream in order to avoid a direct headwind.

A passenger plane typically travels at a speed of 900 km/h relative to the surrounding air. At an altitude of 10 km, where passenger planes mainly travel, the wind speed can reach an average of 150 km/h and sometimes more than 300 km/h. The tailwind gives the plane a fair push from behind so that – in relation to the ground surface – it suddenly flies at a speed of 1,000 km/h or more.
