1. Water, water, water.
I think these first couple of tips might be pretty obvious but I am going to list 'em anyway! I can't stress enough to stay hydrated. This may mean cutting out alcohol or salty foods the day of travel and/or perhaps carrying your own refillable water bottle. It may also mean using the lav more often but do not let this stop you! Planes (and hotels, etc.) are very drying and being dehydrated is not fun. So drink up!
2. Bring your own snacks.
The snacks at the airport are overpriced and you can never guarantee that you'll find something you like to snack on during a long flight. And I don't depend on the in-flight meals anymore because while Delta's are usually pretty good, you just never know and what's worse for your trip than getting hangry?? So stop at Target and get your favorite snack (not too salty and with protein and fiber to keep you energized and full) before you fly. My favorites are trail mixes but I will also bring protein bars.
3. Bring the right pillow and a seat pad.
Perhaps you are someone who can sleep anywhere but alas, I am not so lucky. I bring a travel pillow as well as my trusty seat pad. Don't think twice about spending a little extra on the right pillow (I don't dig those inflatable ones, for instance) or about the space it may take up. In my opinion, it is worth it. A pillow with a snappable strap can help to attach it to your carry-on during transit. The one I have even has a built-in pocket for my i-Pod. My favorite seat cushion is the Therm-A-Rest LiteSeat which you can inflate to your preference but that rolls up nice and small when not in use. Totally worth it.
4. Bring things to do.
Of course! Bring your iPod, Kindle, a paperback, etc. depending on your preference, carry-on, and destination. And bring your own earbuds or headphones because the ones the airline gives you won't be great (or even good).
5. Saline nose spray.
File this under: planes are really dry. I actually tend to get nosebleeds on long flights. Saline spray helps with this tremendously. And a handkerchief or tissue packs are a good idea as well.
6. Layer your clothes.
Running around the airport can be a sweaty, stressful ordeal at times but in hour ten of that flight when you are trying to sleep, it can get cold and that little tissue of a blanket most airlines provide doesn't always cut it. I tend to wear loose-fitting clothes with some give; often the ones I wear hiking which breathe well. I go for pants with no belt (so as to not have to take it off when going through US security) and a zippered sweatshirt with a hood that can double as a back rest or blanket. Oh and for goodness' sake, WEAR SOCKS. I don't know how many times I see people on planes and in the security line who are barefoot. Sorry ya'll but this is gross. That's not water on the floor of the lav, folks. I wear wool socks to keep my pigs cozy the whole flight through.
7. Wear glasses? Bring your case.
I often wear contacts when I am away but on flights, I always wear my glasses. I am sure to bring a hard case for them now because I can take them off for when I sleep and stick the case in the seatback pocket. This way I don't misplace them and they stay safe and clean. I also put my lip balm and earbuds in the case for easy access.
8. Stick to your schedule.
Before and during long-haul travel, I try to stick to my normal schedule as much as possible. This includes when I sleep, when I take any vitamins or medications, and when I eat. As little disruption as possible will minimize jet lag.
9. Don't overindulge.
This goes hand-in-hand with #8. It's easy to indulge in more food and drink or to sacrifice sleep when on holiday. This can lead to illness, stomach woes, or worse. Again, stick to your regular schedule as much as you can and bring some Tums or similar so you can enjoy the local cuisine while at your destination.
10. Consider springing for the upgraded seat.
Now, I am not talking about first class (but if you can afford it, go for it!), I am just referring to the trend of airlines offering special seats in economy for an additional fee. Delta has their Comfort Economy Plus, for instance, that offers a few inches of extra legroom which I find totally worth it. You might find a good return an extra $50 or even $200 investment if it provides a bit more comfort.
BONUS FOR THE LADIES...
Ladies, ever get that not-so-fresh feeling?? Ha, don't lie! We all do, especially on a long flight, so do yourselves a favor and bring some feminine wipes to use during and after your flight. 'Nuff said. (Maybe this is a good tip for the gents as well...??)
