Netflix Offline
If you have a Netflix account, now is the time to make the most use out of it. Before your vacation, download as many movies and TV show episodes as you can. That way, you’ll have something to do during your boring flight. Also, you might want to download a few podcasts while you’re at it.
Just make sure that the airline allows you to use electronics during the flight. We’ve been on planes where the stewardesses were pretty strict about shutting off our electronics, so we wasted a whole bunch of time downloading movies for absolutely nothing. Those airlines are terrible.
