Whether you're on a quick flight, or a long-haul international voyage, your packing should only differ in amounts, as opposed to items. Here are some essential items to pack in your carry-on to make your flight as enjoyable as possible.

1. Moisturizer

If I was on a longer plane ride, I would personally skip the make up all together and focus on skin care. Airplanes are known for being dry, so carrying face and hand cream will prove to be an essential item in your purse or carry on to keep comfortable. Same goes with chapstick!

2. Entertainment of some kind

Not all airplanes provide free movies or have an individual screen, so it never hurts to pack along your own entertainment. Be it a book, music, or movies/TV shows (which are now thankfully available for downloading on the Netflix app), it's best to be prepared. Don't forget your charger and headphones!

3. Neck pillow

I personally have a very difficult time falling asleep on planes, and I need all the help I can get. Purchasing a travel pillow has proven itself to be useful in providing additional comfort at the very least. While a lot of longer plane rides will likely provide a pillow and blanket, having an additional (and likely more comfortable) one may make your journey more comfortable.

4. Passport and other travel documents

This one may be obvious, but keeping these documents in a place that's easy to access without digging through the depths of your carry on is something that should be a top priority. Oftentimes, travel documents will take up the majority of space in your carry on item, so it makes the most sense to pack around them, as they are the items that will be the most frequently pulled out.
