- According to the Transportation Security Administration, there are a number of items strictly prohibited aboard planes across a number of airlines. Generally, weapons are not allowed aboard any plane as carry-on luggage and if placed in checked-in baggage, they must be packed under specific guidelines made by that particular carrier. Also, as a general rule, anything that could be considered a weapon, therefore sharp objects like knives or pick axes, sporting sticks like lacrosse of hockey sticks and other such items are typically banned as carry-on items and must often be checked-in under specific rules.
- In terms of what rules must be followed when packing carry-on items like toiletries, the best rule of thumb would be to think that smaller is better. As a result of a number of incidents aboard planes, the once flexible rules governing toiletries and liquids on flights do not hold true anymore. Typically, airlines will ask that all liquids and toiletries be taken out of carry-on luggage and placed in a clear plastic bag for inspection. Generally all bottles placed in this bag be 3.4 oz. or less and each passenger is only allowed one bag. However, there are some exceptions that can be made for specialty items like medication and baby formula. To speed up the inspection process it is best to declare these items once you get to security.
- Alcoholic beverages provide an interesting issue when traveling. Drinks that contain more than 70 percent alcohol, or 140 proof, cannot be taken in checked baggage. Alcoholic beverages that are purchased after a person goes through the security checkpoint are permitted.
Lighters, after having been banned aboard flights throughout the country, are now permitted to be packed in carry-on luggage. But regular matches, however, are still prohibited in checked-in luggage. People who would like to carry matches must purchase the safety variety.
For all other items, the best suggestion is to simply call your airline and ask the specific policies about what you can and cannot travel with. Sometimes items that you wouldn't think would be a red flag for inspectors could mean a holdup in security and a missed flight.
