For that matter, British Airways has
offices all over the U.S.A...as well as a business license to conduct business in the U.S.A. etc....
So just because BA flys U.S. citizens in and out of the U.S.A. doesn't mean that the
TSA would have jurisdiction about who enters the cockpit of a U.K. registered airplane in Africa.
You wouldn't have an Italian police officer make an arrest of an Italian citizen in the streets of London, or would you?
