Former Continental Airlines CEO and Chairman Gordon Bethune is joining former American Airlines Chairman Bob Crandall in their mutual disdain for the TSA's air marshal program.

Speaking to CNBC's Tyler Mathison and Mandy Drury on Power Lunch,Bethune called the air marshal program "the biggest waste of money we have going in the country today." Crandall made similar comments on Power Lunch earlier this week.

Bethune also said he doubts the airlines will play any dangerous games with overcapacity and will protect their currently profitable business model.
