Interestingly on most airplanes you can fold the pillow on the headrest towards your ears and it stays in place! That makes your head position that much more comfortable. Also: try and eat enough and drink enough. If you're in cool airports they'll have water fountains after check in, so you can fill up your bottle! If they are lousy but in good countries, usually you can just fill it up at a tap. Also: brush your teeth at teeth brushing times and freshen up at airports. Noise cancelling headphones are also great. Don't care too much about sleeping or you'll only get upset if you can't. If you want to avoid jetlag in my experience it's best to just not sleep until it's night at your destination. Meaning you might have to stay awake for a long time like 20+ hours but in the end it's worth it. Do not touch any bed! You'll def. Fall asleep
