I went inside the secret room where pilots sleep on long-haul flights. It was the best seat on the plane.

• Pilots take shifts on long-haul flights. When they're not flying, they rest in hidden rooms.
• I toured the secret room stationed above business class on an Air New Zealand Boeing 777-300ER.
• It was the nicest spot on the aircraft, with two beds, two recliners, and plenty of space.

Twelve hours is a long time for anyone to be on a plane.

But when you are responsible for flying the aircraft, it's an even tougher role. That's why pilots take shifts on long-haul flights.

When pilots aren't in the cockpit, they're resting in secret rooms on board the aircraft.

On a 12-hour Air New Zealand flight from Auckland, New Zealand, to Los Angeles, I toured this part of the plane that most people don't see.

On the day of my flight, I boarded the Boeing 777-300ER early, and Sarita, the flight's in-service flight manager, welcomed me aboard the Air New Zealand aircraft.

Together, we walked past rows of lie-flat seats and into the airplane's front galley.

From the galley, I could see the aircraft's cockpit. As I looked around, I didn't spot any door or signs indicating the pilot's rest area.

Then, Sarita pointed to a camouflaged door. She explained that it was intentionally hidden so passengers don't accidentally disturb the resting pilots.

Sarita entered a secret code and opened the latch. Behind the door was a narrow, steep staircase. I climbed up and was immediately shocked by the room's size.

Although I couldn't fully stand at 5 feet and 8 inches, the room had enough space for two reclining chairs and two beds.

She said that on most long-haul flights, four pilots split time between the cockpit and the rest area. Rules require that at any point during the flight, there be at least two pilots in the cockpit.

The flight's captain typically decides when the breaks happen, but like flight attendants, pilots typically take their breaks in two-hour slots. Once on a break, the pilots spend their time in the recliner, a bunk-style bed, or a combination of both.

Regardless of where they were resting, each area had seatbelts for safety.

The pilots also had a TV similar to the one I had in business class near the recliner chairs. Nearby was a plug, temperature control panel, and cupholders.

Between the seats, the pilots had a phone to communicate with the cockpit and flight attendants in the cabin.

Behind the leather seats were two cubby-style beds.

The narrow beds each had a curtain to block out light and allow for privacy.

Inside the sleeping cubby were two sets of blankets and pillows similar to the ones I had in business class. The mattress on the bed looked comfy enough for a decent nap.

Along the edge of the bed, I spotted more cupholders and a control panel for lights and airflow.

As I descended the stairs, I spotted a wardrobe. Sarita told me that's where the pilots store parts of their uniforms while they rest.

I felt spoiled in my business-class seat, but the pilot's room was even more luxurious. They had privacy, space to stretch out, and a larger bed than my lie-flat seat.

And, of course, those perks were well-earned. On my flight home, I slept better knowing the pilots had room to rest and re-energize for some of the world's longest flights.
