I’m writing this from the cabin of a JetBlue plane somewhere over the Atlantic.
I just looked out the window and saw the engine read “www.jetblue.com.”
Now why would they advertise their URL to people already on board, I thought.
But, aha! … It’s there for all the people who like to take photos out the window, with the jet engine in the foreground. Post that on Flickr or Facebook, and you’ve just advertised for JetBlue to your friends and family.
