D.C.'s youngest giant panda is settling into a new life.
Bei Bei, who has spent his entire life at the Smithsonian's National Zoo, took off from Dulles International Airport about 12:15 p.m. Tuesday aboard a special FedEx plane, which is carrying him on a nonstop flight to Chengdu, China.
After a 16-hour direct flight, Bei Bei landed safely. A panda team will monitored him continuously during the trip, according to the zoo.
All giant panda cubs living at the zoo move to China at age four, due to an agreement with the China Wildlife Conservation Association. Bei Bei celebrated his fourth birthday in August.
Like most 4-year-olds, Bei Bei will have plenty of snacks for his flight. In his case, that will be bamboo, apples, sweet potatoes, leaf eater biscuits and water.
As the panda Bei Bei’s departure for China approaches, NBC News4’s Eun Yang headed to the zoo to help make a frozen fruit cake for his farewell party.
Bei Bei's big travel day began when he left the zoo shortly before 9 a.m. Tuesday, aboard a truck that brought him to the airport.
The 240-pound panda is travelling in a specially designed crate, to which keepers worked to acclimate him ahead of time.

Bei Bei weighed nearly 21 pounds in the first week of January, and was learning to climb the rocks in his enclosure. He was still a wee one, though -- Mama Mei Xiang still nurses him and carries him around.

On Oct. 1, 2015, Bei Bei weighed in at 4.5 pounds -- half a pound more than his weigh-in the previous week. He was measuring nearly 14 inches from his head to the tip of his tail.

At about three weeks old, the cub was looking decidedly panda-like. Here is he at 1.9 pounds on Sept. 14, 2015.

In mid-September 2015, the zoo said that the newborn was sleeping for much of the day, which is normal. Keepers said he sleeps with his paw over his eyes -- just like dad Tian Tian and big sister Bao Bao do!

On Sept. 12, 2015, mom Mei Xiang left the den for about 15 minutes, and the cub was spotted on the panda cam scooting around in circles, the zoo said. Keepers noticed the black markings on his back resemble those of dad Tian Tian's.n

Keepers described Mei Xiang as a devoted mother. She gave birth to twins Aug. 22, 2015, but as many giant pandas do, struggled to care for them both. Keepers swapped the cubs back and forth, but the smaller cub died four days later. Bei Bei, the surviving cub, was healthy. Here are mom and baby in September 2015.

In mid-September 2015, keepers said the cub's eye slits had formed and his eyes would begin to open soon. Panda cubs' eyes fully open when they're about 6 to 8 weeks old, the zoo said. (Image from Sept. 10)

His new home will be the Bifengxia Panda Base, one of the bases operated by the China Conservation and Research Center for the Giant Panda. A keeper from the American team will stay with Bei Bei while he adjusts to his new home.
Bei Bei will join the giant panda breeding program when he is between five and seven years old, according to the National Zoo and Conservation Biology Institute.
As the panda Bei Bei’s departure for China approaches, NBC News4’s Eun Yang headed to the zoo to help make a frozen fruit cake for his farewell party.
His departure from the zoo makes his parents empty nesters. Mei Xiang and Tian Tian's two older offspring, Tai Shan and Bao Bao, have also moved to China. However, the National Zoo said Bei Bei won't spend time with his siblings, since pandas are solitary in the wild.
The zoo hosted daily events in the week leading up to Bei Bei's departure and streamed 24/7 footage of Bei Bei on one of their panda cams.
