This will take some time to roll out, for instance my flights on American last night still aired the older videos that American has been playing for years (which featured different crew members speaking different parts but that was generally corporate and straight-forward). I expect my American flights today will still have the older video as well, and of course MD80s don’t have inflight video at all.
However the new video is more modern, it has a little bit too long of a lead-in in my opinion, but is more ‘fun’ without being too cheesy either.
