Writing this from 34,000' right now... and watching my battery drain. I searched to no avail. I have the airline adapter and bought the Magsafe > Magsafe 2. I have used this a couple times with my new rMBP and while it doesn't charge, it at least doesn't discharge. Today I'm plugged into seat power and... nothing. I have the green light, so it's getting juice, but there's no charge or "not charging" or anything. The machine is acting no differently than if I was on pure battery. Any ideas???
