We have put together a list of absolute must-packs when packing your carry-on, to make sure your traveling experience is as comfortable and enjoyable as possible. This is where items like headphones, snacks, and hand-sanitizers come in.
And of course, while it’s only the worst-case scenario, there’s a possibility that your checked luggage might not make it to your destination when you do. So you’ll also want to board with anything that would make it less of a headache to spend a day or two waiting to be reunited with your belongings.
Snacks

Traveling or not, it’s always a good idea to have a snack in your bag. Try to avoid overly salty foods as, during the flight, you lose a lot of water from your body due to dry, air-conditioned air in the plane. If you skip drinking enough water, soon you will feel fatigued, and your head will start to ache. Good ideas could include nuts, granola bars, popcorn, or pretzels.
Hand sanitizer

It’s not news that airplanes are blanketed in bacteria, so cleaning your hands can help you dodge getting sick and spreading germs to others.
Studies have found that sanitizers with a higher alcohol concentration of at least 60% are more potent when it comes to killing germs than those with a lower alcohol concentration or non-alcohol-based hand sanitizers.
Neck Pillow

The wonderful world of neck pillows, with many products out there to choose from, these plushy reinforcements will help you to sleep better while traveling and arrive refreshed to your destination
Headphones

If the constant sound of jet engines or the distracting cry of babies seems to prevent you from enjoying your trip, the best solution is to invest in some noise-canceling headphones.
Listening to music, podcasts, or an audio book can have a profound effect on your state of mind by keeping you calm during your flight and can make it more pleasant.
Sleep Mask

Whether you would like to sleep on your trip or would like to nap, one of the best ways to do this is to wear an eye mask. The most critical component in a good eye mask is that it blocks out all light and isn’t too tight around your head, offering a complete seal around your eyes to block out any light.
