Be aware that a swiss knife is not allowed inside the plane but it is okay when you place it in the baggage check in. The airline attendant said that a swiss knife can be used by criminals inside the plane, that's the rationale of the prohibition. In our flights to a foreign, we usually do not have baggage allowance to save on the fees since the hand-carry bag is enough for our things. What we buy with the plane ticket is the baggage allowance on our way back home. In our last flight, I forgot to remove my swiss knife from my vanity bag which is in our hand-carry bag. It was caught by the x-ray machine. The security officer advised us to check in our baggage so the swiss knife can go otherwise it will be confiscated. And since that swiss knife is a souvenir from my father, I was forced to check in our hand-carry bag... to a very expensive charge of $20. Ouch!
