Umm Gravity ?

Planes flying in the opposite direction of Earth's rotation don't reach their destination more quickly because their speeds are measured with respect to the surface of the earth, not the earth's center.

Planes don't fly in reverse ;)
Well I think you missed a bit, I think the plane is supposed to be flying at the same speed as the earths rotational orbit. It would never leave where it left.

properly, if planes fly east, they fly with the rotation of the earth. in the event that they fly west, they fly against it. Planes do not fly in right this moment strains. on the floor of a sphere, the shortest distance between 2 factors is a huge circle. subsequently you fly over Greenland to get to Canada. examine out a globe of the earth particularly than an atlas, and you will see what I propose. As for you final question, the earth rotates as quickly as each and every 24 hours!! in case you look down on the north pole, the earth rotates anti clockwise.

Because everything within the Earth is also moving at the speed of the Earth's rotation. Even just sitting still, you would be moving at 18 km / sec. Relative to the Earth you don't feel it because everything is moving at that speed.
So relative to the Earth your speed is just the typical speed you read on a speedometer. But relative to space your speed is the speed you are moving + speed of the Earth.

Because the air and the aeroplane also rotates along with the earth at the same speed and the relative speed is the thing that matters as far as journey time is concerned.

Because the atmosphere and everything in it rotates with the earth, the planes motion is relative to the air flowing over its wings.

If we think like that.
earth = bus
plane = a fly in the bus.
air is also moving whit it. If not you can see the fly at the back window of the bus , like Garfield :)
Also earth is look like that. If not there must be a wind and it's speed must be 18 km/sec in everyday.
Have nice day.

In Concorde you used to be able to see the Sun rising in the West, everything else (unless you own an F22 or an SR71) is too slow.
