hey! i just got my macbook a couple days ago and i will be flying for university in august. i'll be flying singapore airlines and its going to be a b777-300er plane and i checked, they have a socket or something for you to charge your laptops and stuff! i'm not sure if i'm supposed to bring an adapter or something but they said it would be a 110V AC in-seat power supply. can i just bring the charger or do i have to bring something else? THANKYOU!
