U.S. flight attendants are fed up like their Air Canada peers. Here's why they're unlikely to strike.

At the end of work trips, Nathan Miller goes home to a makeshift bedroom in his parents’ house in Virginia. The 29-year-old flight attendant is part of a PSA Airlines crew based in Philadelphia, but Miller says he can’t afford to live there. He makes about $24,000 a year working full-time for the American Airlines subsidiary. Despite often staffing multiple flights a day, Miller commutes by plane between Virginia Beach and Philadelphia International Airport, a distance of about 215 miles.
