You can buy an airplane connector for about $100 I think. Probably cheaper online.

Since I work in the cockpit, I usually just plugged my laptop brick into the 115 volt outlet next to the flight engineer station. Yes we have 115 volts, but it is 400 hz. The brick doesn't care- it makes 19 volt DC power no matter what you put in it- 115 volts, 240 volts, 50 hz European power, 400 hz airplane power, et cetera. If you don't believe me, read the fine print on the back of your brick. These work world-wide. I've even had my laptop on in a hotel room in Siberia. And 31,000 feet over Siberia-

The thing about those airplane connection kits? Most airlines only have laptop power connections in business class. You can go ahead and buy one, but if you are in coach you might be self-contained; Battery power only. Check with your airline.
