Because at different altitudes the friction factor can be bigger or smaller in relevance to how thick the air is?

So, are these winds always the same? Blowing towards the same direction? Because it always take 45 minutes longer to go therefore 45 minutes less to come.

Yeah, but it rotates to one direction. Let's say the plane is going the opposite direction?

Does it have any relevance to the rotation of the earth? If you are going with it you go faster, if you are going against it you go slower? Or it doesn't matter because the atmosphere of the earth also rotates?

I was wondering... I'm currently living in Cyprus and study in the UK. When I take the plane from England to Cyprus the flight takes more or less 4 hours. When from Cyprus to England it takes approximately 45 minutes more. Same plane, same speed, same distance. Thanks
