Hey guys, I'm going to be going to Italy for study abroad in about a month (excited already!) and need to bring my laptop to do work on, etc. Yes, it's more than just vacation However, it's also a 9 hour plane trip (to frankfurt), a 3 hour layover, and then another several hour flight to Rome. My macbook gets about 3 hours of battery life, so while I'm not going to be using it the whole time, it'd be nice to be able to use it without concerning myself too much about battery life. I'm flying Lufthansa, and I heard that more and more, longer flights/bigger airplanes now have ports on arm-rests to plug in and get charged. Does anyone know how this works with the macbook charger, if lufthansa has these ports, and where to get an adapter?
