A look inside the secret, crew-only lounge where flight attendants hang out when they're not flying

• Flight attendants don't spend all their time on planes.
• When they're not flying, they may be hanging out in their secret crew lounge inside the airport.
• Robert "Bingo" Bingochea, a Denver-based flight attendant for United Airlines, gave us a tour of United's crew lounge inside Denver International Airport.

Flight attendants are like the tech workers of the airline industry.

Without them, nothing would run smoothly. They keep odd hours. And they even have their own nap rooms.

While you may not think of flight attendants as your typical office dwellers, when they're not flying or recreating, there's a good chance they're hanging out in their airline's employee-only facilities inside the airport.

Not every airline has their own employee facilities in each airport. United Airlines, for example, has them at their hub airports including Newark International Airport, Chicago O'Hare International Airport, and Denver International Airport.

These employee facilities not only house flight attendants' beloved crew lounge, but also conference and meeting rooms, training areas, computer stations, and different departments including HR and IT.
