The National Zoo is packing up its American-born panda cub Bao Bao for a one-way flight to China, where the 3-year-old will eventually join a panda breeding program.

The cub won’t have to worry about finding overhead bin space or dealing with a talkative seatmate on the 16-hour, nonstop flight Tuesday afternoon into Wednesday. She’ll be the only panda on the plane, traveling with a keeper and a veterinarian. Her accommodations are first class, too: a special metal crate the size of a double bed she can stretch out in. A sticker on its outside announces its contents: “one panda.”

In preparation for the trip, keepers have a packing list of Bao Bao’s favorite foods including: 55 pounds of bamboo, 5 pounds of apples and 2 pounds of sweet potatoes. Panda keeper Marty Dearie, who will travel with Bao Bao to China, said pandas spend 13 to 16 hours a day eating.

Bao Bao is scheduled to depart the zoo Tuesday morning and travel to Washington Dulles International Airport in northern Virginia, where she’ll board a special FedEx plane. Fans will be able to watch her departure from the zoo and airport on the zoo’s Facebook page.

Once Bao Bao arrives in Chengdu, China, she’ll be driven to her new home, one of the bases run by the China Conservation and Research Center for the Giant Panda. In time, when she reaches sexual maturity, between 5 and 6 years old, she’ll become part of a panda breeding program.

Laurie Thompson, the assistant curator of giant pandas, said keepers have been preparing Bao Bao to leave for China since she was born, teaching her behaviors that will allow her Chinese keepers to do things like draw blood and perform ultrasounds. Thompson said Bao Bao’s departure is “definitely bittersweet,” but her keepers “know she’s ready” to leave.
