I am finishing up a semester abroad and will be backpacking over my winter break. This means that I need to ship home everything that won't fit in my backpack. The shipping company won't take my laptop, so I'd like to send it home with a friend who is flying back (London > New York on United). Is she allowed to carry both her laptop and my laptop in her carryon bag? I have heard that you can't have two computers but can't confirm anywhere.
