There appears to be a lot of confusion about getting TSA Pre on your boarding pass which allows you to access the TSA Pre expedited line at airport security. There are are several Homeland Security programs that will dramatically increase your chances of seeing TSA Pre on your boarding pass, regardless of ANYTHING your airline might do. The two biggies are the TSA Pre and Global entry programs. Anyone on this forum wants Global Entry. You have to PAY Homeland Security for either but not the airline.

Outside of these programs, the airline can CHOOSE to assist in getting TSA Pre on your boarding pass and that is what some airlines are trying to charge you for. In the beginning they did so as a SERVICE more so for frequent flyers.

At the end of the day, the TSA Pre line (domestic) may or may not be shorter. I have never seen a case where the Global Entry line (international) was not much shorter.
