Incorporating an Olympic theme isn't a bad idea. But there's a strategic question for United. How jingoistic should the video be? Granted, United is a US carrier, but it has a global market. While they could have used the same imagery and themes to tie into the Olympics generally, they definitely wove in a lot of "Team USA" imagery and language including a U! S! A! chant at the end.
I happened to be on a United flight taking off from Italy. At least half of the aircraft was not from the U.S. I wondered how they felt??
