Mark, are you saying TSA pre-check will not help people returning to the U.S. with a 1:25 connection? Atlanta is where I need a Global Entry card (if I can get one) because of immigration, customs, and bag re-check.
When the pre-check program was rolled out, I read it is limited to people who are frequent flyers on certain airlines. For me that airline is Southwest - which, of course, was not an option for flying internationally. Has this changed to allow infrequent Delta flyers to get GE cards for international travel?
Several issues to answer here. First, understand there are several programs with different benefits.
TSA Pre-Check only allows for the PreCheck lines at US airports if flying a participating airline.
Global Entry - Allows for expedited re-entry into the US and also provides the TSA PreCheck.
Nexus - Allows for expedited US-Canada border crossings as well as TSA PreCheck.
You MUST enroll in one of those programs and then provide your Traveler ID number to your airlines. They print your PreCheck status on your boarding pass.
PreCheck and the other programs have nothing to do with frequent flyer programs. Those with elite status do usually get it as part of their status, but anyone with a clean record can apply and get enrolled.
