While not Gatorade or Powerade, I do remember Delta for a time a few years back, was offering Vitaminwater. AirTran currently offers Vitaminwater as well as Smartwater.
Going over the websites of UA
, US, G4
, and NK
, nobody seems to offer Gatorade or Powerade, even as a buy on board option (Other than FL
and Vitaminwater and Smartwater.).
