We fully understand that many types of adventures have a sell-by date: If you're older than 18, anything that involves wheelies, jumping off of ramps, or a special slot in the X Games is probably a bad idea. A shot of adrenaline to a 9-to-5 life, though, will not only take you out of your comfort zone—it'll get you out of your zone altogether.

You can 'fly with everything you buy' after security. The exception is Australia where you cannot bring in any liquids over 100ml.

As of August 10, 2006 passengers must bring limited quantities of liquids, gels and aerosols (if any) with them when they travel, while maintaining a heightened level of security.
