1. The letter did not need to be open at all. If you want to travel the country for 30 days without paying, more power to you but why not just send it to the jetBlue CEO directly?
2. The people behind this letter obviously think their idea is amazingly brilliant. Which it isn't. Everyone has interesting stories. You could go into a Dunkin' Donuts at 3AM and hear some pretty crazy stuff. No need to be at 30,000 feet.
3. These people probably WILL get free flights or some other special support from jetBlue because God forbid a publicly-traded company didn't listen to any and every simple Jack who asked for something on the internet.
