Your so sure about cz, but you forget how much aa loves tsa, they do have a history, to the tune of aa connex with 145's at tsa, which aa was fed up with its poor quality and constant FAA fines/grounding of aircraft and got dropped from aa. You mean that great quality? Its known aa always liked chq and recently have really good relations with rah. They loved using chq as a bargaining chip, much to the chagrin of the chq pilot roup.
