I have shipped and also checked it at the airlines. I do not carry on luggage, just laptop. Both shipping and check in work fine. I have never had a problem with either. If you ship make sure that the place you are sending it to is aware and will sign for the package. Also make sure that you have enough insurance to make you feel comfortable if there is a loss. Both UPS, USPS and FedX have a standard $100. loss insurance. Addditional insurance can be purchased. Package so as to draw attention to your stuff. If you check in at the airline you can also ask them about addtional insurance. Not all carriers have this available. With the airlines and TSA do not use aluminum rod tubes. Plastic cordura or PVC tubes work better. When shipping across country leave yourself addtional time in case of weather or other possible disruptions in shipping.
