A Vietnamese man trains for catching his flight by taking two suitcases on a treadmill.

Partway through his run he also practices checking his watch while running and carrying the cases to ensure he's keeping good time.

"It is all about running while we are stuck in the traffic in front of Tan Son Nhat Airport or Hoa Hung station in Ho Chi Minh City, Vietnam," said the filmer. "We need to train for it."
