One crucial item you must pack for every flight — it’s only 5 bucks

I’m always offering valuable packing advice, and after taking hundreds of flights, I thought I’d offer my one crucial packing tip you’re probably not applying. In fact, here’s my one and only packing tip for your next long flight — and it will cost you only $5.

When you’re packing for your next long flight, buy a beverage with electrolytes, like Smartwater, Gatorade or Vitamin Water, which you can stash in your checked luggage. Because you can’t pass airport security with liquids, you can buy these beverages at shops outside the gates for your carry-on.

The reason why this is important is because cabin air on a plane is incredibly dry. In fact, the humidity level is drier than the Sahara Desert. The longer the flight, the more dehydrated you’ll get. Honestly, it’s my one and only packing tip for a long flight because it’s so important and great for your health and skin.


Even if you’re taking a short flight, you’ll get dehydrated, which can leave you feeling dry eyed, sluggish, weak and dizzy. Electrolyte beverages fasttrack hydration levels, as in they get you more hydrated than a glass of water, thanks to the electrolyte minerals of Sodium, Magnesium and Potassium.

You can buy a beverage with electrolytes at the airport.

Dehydration is not great for you, and it can leave you extra tired when you arrive in your destination, so this is a wonderful hack I picked up. Also, drinking water on a flight is fine, but you may constantly chug bottles of water that leave you going to the bathroom often.

The feeling of being hydrated.

Another point: Most hotels have recycled air, meaning the air is circulated and extremely dry. This can take a toll on your health and your eyes (bring eye drops).

There’s nothing more wonderful than taking a long flight, arriving in my destination, getting to my hotel, and opening my luggage to find a bottle of electrolyte water. Not only do I save money by not opening water in a mini-bar (which can be up to $10), this has been a blessing in destinations where you can’t drink tap water (like Thailand or Mexico).

Hotel rooms have dry, recycled air.

Having an electrolyte beverage on a plane is also helpful. This prevents you from having to chug bottles of water to get hydrated.

When I pack, having a Smartwater or Gatorade is the only thing that comes to mind first… and it’s that one thing people regret not packing because it’s just so useful during a flight and after you land.
