Canada and UK's immigration and checkpoint system is pretty much similar to ours: same redundant and doofus TSA like security, no passport checks or exit stamps to leave Canada, direct secure areas feeding into Canadian immigration and customs control from international flights, yet they have an efficient system for ITI passengers without the stupidity of all deplaning passengers to enter Canada and collect their bags to recheck. For many, flying NRT-YVR-MEX is much more easier than flying NRT-LAX-MEX because of this; Canada does not require passengers ongoing to an international destination to enter Canada, they can remain in a sterile zone by just following signs that says "international transit passengers." Without the need to wait in long lines or waiting for bags to come, ITI in Canada is much more smoother than any of all the mishaps that may happen when transiting in the US.

American and JetBlue also announced today that they have agreed to begin a frequent flyer relationship later this year. Members of American's AAdvantage® program and JetBlue's TrueBlue® customer loyalty program will be able to earn AAdvantage miles or TrueBlue points, respectively, when they fly only on the cooperative interline routes listed below.
