These last couple years, especially since going to college, I have been on airplanes going places more frequently and I have picked up a few key items I always have with me along with some travel day tips and tricks.
Check the weather
My first step before I begin to pack is to check the weather of the location I intend on traveling to. This will help you sort out the types of apparel you may need.
Make a list
Personally, I am a list person. Once I write it down it down it almost guarantees I won't forget it. It also helps me stay organized with all of the this I think I will need and that way I can pack my carry on properly to ensure everything will fit.
Bring an empty water bottle
Staying hydrated is essential to your everyday living and when you're embarking on a long travel day it can be forgotten. Therefore I always bring along an empty water bottle so that I can be reminded to drink water. It will also help reduce future costs of over prices drinks in the airport or perhaps your destination.
Bring noise canceling headphones
These are my holy grails for any flight. Headphones are a must to let yourself stay distracted on planes. Yet I would highly encourage you to invest in noise canceling headphones, they are a real game changer. They block out the annoying sounds of your flights. I often will even put my headphones on without any sound just to block out the noises so I can sleep.
Wear your biggest jacket
I always try to wear my biggest articles of clothing on the plane so that I have more room in my carry on. This usually means I will throw on my sweatshirt and an outer layer jacket. Wearing a big comfy jacket is also used in more than one way because you can use them as a jacket or pillow on the flight as well.
