For the first time in my life in half a year I will be traveling half across the globe by plane visiting the UK, HK and AU. I want to take my MBP Yearly 2011 with me and so I need to stay powered on and online during my travels. So I need a complete set of accessories: power plugs, plane charger etc.. . I was considering getting Apple's official travel kit, and airline adapter but a few commenters on Amazon pointed out that the airline adapter is designed for some exotic slot format which very few planes have and Apple's travel kit is not designed to be used with the extension cord. Could you please offer me advice on which plug sets and plane chargers you personally use (manufacturer/model) and which are good and offer enough value for your money? Maybe some other things I am not aware of.. Thanks!
