According to a GQ profile in 2010, Kobe would use the helicopter to fly from his home in Orange County to Lakers home games and elsewhere. Kobe reportedly took advantage of the helicopter to help stay fit for games:

"But sexy as it might seem, Bryant says the helicopter is just another tool for maintaining his body. It's no different than his weights or his whirlpool tubs or his custom-made Nikes. Given his broken finger, his fragile knees, his sore back and achy feet, not to mention his chronic agita, Bryant can't sit in a car for two hours. The helicopter, therefore, ensures that he gets to Staples Center feeling fresh, that his body is warm and loose and fluid as mercury when he steps onto the court."
