What may be forbidden to take into plane when you go abroad?

dont bring anything that can used as a weapon. this includes nail files, nail clippers etc. dont bring any liquids..there is a limited amount you CAN have with you, but it just isnt worth the bother when you buy shampoo or mouth wash when you get here. its better to not have anything that MIGHT be suspicious to the inspectors..cause even if the liquid turns out to be nothing, you've still had to sit hours on end while they verify what it is. other than those things i mentioned above..i think thats pretty much it. anything you have a doubt about, pack into the suitcase that you check to the cargo hold. they are not nearly as concerned about what is in there as what you are taking inside your carry-on bag. If you still have worries, call and ask someone at the Airline who you are booking your flight with, or your travel agent. they will surely be able to tell you the do's and dont's.
