Chauming, your rights depend on the reason you were kicked off the plane. What was the reason that the airline gave you that you were removed? This you have not told us. They must have said something when you asked why. There are many, many reasons in which the airline has every right to have a person removed from a flight. There are also many instances where if you are removed involuntarily that some sort of denied boarding compensation is due to you. But no one can give you the advise you request without a more specific account of just what occured in your instance.
