According to a communication from American Airlines, changes are coming to the TSA PreCheck program this month. The change specifically targets users opted-in to the PreCheck program via Airline loyalty programs. If you are not familiar with this scenario, some airlines would opt passengers into PreCheck due to their status instead of them applying for the TSA PreCheck program directly. If this applies to you then, you will find yourself soon see yourself getting declined expedited screening more often.
The reason for this is clearly that there are too many people eligible for TSA PreCheck now. As a result, these lines are getting longer and the benefit is declining. I think this will be a good change and should help the lines at some of the busier airports in the mornings.
If you aren’t in the TSA PreCheck program now, you can always join (assuming you qualify). If you have been getting TSA PreCheck from your airline directly, know that this doesn’t qualify you to get through the traditional TSA PreCheck enrollment procedure any faster.
