It’s interesting to me that so many airlines decided to do this. Was it to keep up with the Joneses?
It’s also interesting to see the different uniforms, the company’s facilities, and the way they approach it. (well choreographed, dressed in their sunday best, casual, or ragged video on their lunch hour)
The American pilots were stuck in the TSA line and couldn’t make it… But American Airlines gals turned up for their own viral video last year…
They may have been late but they actually did show up. Not only once, but several times, because individual American Airlines airports did their own videos.
I dunno wtf Jerusalema is but yay for people having fun.
This!

And Austria Airlines FTW! 
A song I think? Can’t say I like it.
