    So besides the typical turning this n that off. Is there really another way to charge or have some sort of mobile quick charge for flights with no in seat charger? Thanks!

    There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for tips on extending it.

    This should answer most, if not all, of your battery questions:
    Or you could buy one of these.

    Screen brightness has a large effect on battery life.

    If you aren't able to use a power source and have to survive strictly on your battery, my advice is to turn your screen brightness down to two bars, turn off WiFi and Bluetooth and close any programs not in use. I can get 4.5 hours of video playback on my 2010 11" MBA when I do this, it has gotten me through every flight so far with battery life to spare. :)

    For those who don't want to sit through the video, the recommendations are:
    • Use the YouTube HTML5 Video Player
    • Install Adobe Flash 10.2
    • Install Install ClickToFlash to control which Flash content plays on websites.
    • The final recommendation is wrong. That video suggests calibration every month, which isn't necessary.

    The built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration like the removable batteries.

    Read the Battery FAQ.

    If you'll be watching movies with it, convert those movies to 480p first. You won't notice much difference on the smaller screen, and it'll save your battery a bunch of juice.

    HandBrake is what you can use to convert (it is free and save to use, just google it).

    thanks for the tips fellas. Sadly I don't have enough time to order any external backups. Flight leaves this sunday. At one point it's a 15hr flight. =\ first class seats is the only section that has a power supply located in the seats.

    Guess i'll just have to use it strategically and sleep for a bit.

    If you have a 2010 or earlier MBA not running Lion, cookbook helps.

    An iPad (10 hours) + MBA could get through even a 15 hour flight.
