To protect the nation's air travelers, federal air marshals deployed after the 2001 terrorist attacks try to travel incognito, often in pairs, and choose flights identified with the potential to fall under threat. And they almost always fly first class—something some airlines would like to change. With cockpit doors fortified and a history of attackers choosing coach seats, some airline executives and security experts question whether the first-class practice is really necessary—or even a good idea. It could weaken security by isolating marshals or making them easier for terrorists to identify, airline executives say.
