For what it's worth, I was on some Delta flights last week and I think I saw this ad on the plane (I recognized the shot of a turtle swimming). At the time, I didn't even realize that it was about diving. They played it in the middle of a string of destination ads, which came after a movie, and after some sitcoms. I doubt many on the plane were still paying attention to what was on the TV screen. You needed headphones to hear the audio.
