A piece of advice

If you are a first time traveler or somebody who rarely takes the plane, one thing you should do before going on a trip, is to check the do's and don'ts of what to pack and how to pack!

I can't understand that up to now, there are a lot of people who think that carrying a knife, multi-tools, box cutter/blades and the likes are allowed on their carry-on bags. A lot of things have changed since 9/11 happened. Please be more conscious of what you pack and carry.
