* Bring a pair of socks only for the flight, and throw them away afterwards (Uniqlo has decent ones that aren't too pricy). The bathroom floors get so sticky after 10 hours.

* Boeing 777s have the loudest jet engines you can encounter. Choose an A380, 787, or A340 flight if you can manage. If you must ride a 777, the front of the cabin is a little quieter.

* If you are seated next to somebody who needs a little more space, try to politely and subtlety ask an air hostess if another seat is available. Both you and the passenger whom you were seated next to will both have a better flight experience.

* Quite a few airlines will let you choose your meals online if you have dietary preferences. Make sure to check the airline website page in your reservations section.

* Try to grab a few Ursa Major face wipes off of Amazon to freshen up mid- and post-flight. Burts Bees wipes are great too, but a little bulky.
