It the earth is rotating as you claim it does, it depends on which direction you are traveling.
Because the earths air is inside of the atmosphere bubble of the earth it is traveling at the same speed as the earth is though there are elements that cause air to move faster then a 1000 miles a hour within the bubble a example would be like standing on a marry go round(earth) a person(air)standing on it is chewing gum and then spits out the piece of gum while the marry go round is spinning the gum isn't going to hit you right when it comes out of your mouth. No because the speed is created by a person which the gum is shot out faster then the marry go round is spinning.
