Just noticed that the version posted on Hulu has a flight from Delta Airlines come up in search. The one posted here has a flight from American Airlines. Seems that Google put some effort into remaining airline neutral.
It's way more likely that the results that came up for the AA flight were not exactly what was requested (although 100% what I'd want to see if I was searching for one of the other items on the page).
The YouTube one is older... so maybe Delta partnered with Google for a product placement? The Super Bowl version is a bigger deal than the YouTube one after all.
