Closer to 12 hours.<p>Read, watch videos that I&#x27;ve downloaded (unless there are on-demand movies), listen to music&#x2F;podcasts, play games on my tablet, snooze.<p>Maybe it&#x27;s just a function of traveling a lot but I&#x27;ve pretty much got a system down for my in-flight entertainment. I don&#x27;t really care that much about in-flight Wi-Fi. Sometimes I really need to work on something but generally I find it&#x27;s hard to use a laptop on a plane unless I&#x27;m flying business.
