Johnny Jet is going to Europe and he's found a great website for saving money on international travel - Momondo.com. This one site serves over 900 different sites and it not only offers airline, but also train travel. They also bring up the low fare carriers which help you to save a bundle if you're flexible enough.
Johnny also came across a story of a traveler who was thrown off a plane for taking a picture of his seat! Many airlines have a policy against taking pictures onboard and it's up to the discretion of the airline captain whether to take action or not. There are many other places that you should think twice including hotel lobbies.
