When it comes to air travel rules, there are many travelers who automatically assume that they already know what these rules are; however, the reality is that many do not.  In fact, there are some many air travel rules to follow, that it is difficult for any one person to know and fully understand them all.  This does not mean that you should not famialrize yourself with the rules of air travel; it just means that you should try and focus on the most important ones.
One of the most important air travel rules, that you must follow, pertains to the items that are prohibited on airplanes. When further examining these items, you will need to learn which items are only prohibited from being in your carryon luggage and which ones are prohibited from airplanes altogether.  In your examination, you will likely find that flammable or explosive objects are not allowed on airplanes, under any circumstances. This means that you cannot bring gun powder bombs, flares, or even cigarette lighters aboard a plane.  Trying to could not only lead to your items being confiscated, but it could also lead to you missing your flight or being detained by airport security.
Although the ban of sharp, explosive, and flammable items is considered common sense, there are other bans that are not as easy to know on your own.  One of those bans is the current bad on all liquids. This ban only applies to your carryon luggage.  It was recently learned that explosives could easily be held or converted into liquids; thus the reason for the ban.  This ban not only applies to the food or drinks that you consume, but your health and beauty supplies as well.  Instead of carrying these items in your carryon luggage, you will need to put them in your checked baggage.  This liquid ban only has a few exceptions, such as baby formula, prescription medication, or small amounts of non-prescription medication.
