Detective Pux here, and I've solved some of the most baffling cases in my career. But today, I'm here to tackle a mystery that has puzzled travelers for years: what are the things you should never forget to pack in your carry-on bag?

First of all, let me say that packing for a trip can be stressful. You've got to make sure you have everything you need without overpacking and getting charged for overweight baggage. But packing your carry-on bag is even more important. After all, it's the one bag you'll have with you on the plane, and it needs to contain all the essentials you'll need during your flight.

So, what are those essentials? Here are my top recommendations:

1. Your ID and travel documents. This might seem obvious, but you'd be surprised how many people forget this one. You need your passport or ID to get through security and board your flight, so make sure you have it handy.

2. Medications. If you take any prescription medications, make sure you pack them in your carry-on bag. You don't want to risk losing them if your checked baggage gets lost or delayed. And if you're prone to motion sickness or headaches during flights, pack some over-the-counter meds as well.

3. A change of clothes. You never know when your checked baggage might get lost or delayed, so it's always a good idea to pack a change of clothes in your carry-on bag. Plus, if you spill something on yourself during the flight, you'll be glad you have a fresh shirt to change into.

4. Snacks. Airline food isn't always the most appetizing, so pack some snacks to tide you over during your flight. Just make sure they're TSA-approved and won't cause any issues going through security.

5. Entertainment. Whether it's a book, tablet, or portable gaming system, make sure you have something to keep you entertained during your flight. Trust me, you don't want to be stuck with nothing to do for hours on end.

Now, I know what you're thinking: "But Detective Pux, what about all the other things I might need during my flight?" Good question. Here are a few more things you might want to consider packing in your carry-on bag:

6. Headphones. If you plan on watching a movie or listening to music during your flight, bring your own headphones. Not only will they be more comfortable than the ones the airline provides, but you'll also be able to use them with your own devices.

7. Travel pillow. If you're planning on sleeping during your flight, a travel pillow can make all the difference. Just make sure it's inflatable or compressible so it doesn't take up too much space in your carry-on bag.

8. Chargers. Make sure you pack chargers for all your electronic devices, including your phone, tablet, and laptop. You don't want to run out of battery mid-flight.

9. Toiletries. If you're taking a long-haul flight, it might be a good idea to pack some toiletries in your carry-on bag. This could include things like toothpaste, a toothbrush, and facial wipes.

10. A jacket or sweater. Even if you're traveling to a warm destination, planes can get chilly. Pack a jacket or sweater in your carry-on bag so you don't freeze during your flight.

Now, I know that's a lot to remember, but trust me, it's worth it. Having all these essentials in your carry-on bag can make your flight a lot more comfortable and stress-free. And if you forget something? Well, there's always the in-flight magazine to keep you entertained.

In conclusion, packing for a trip can be overwhelming, but packing your carry-on bag doesn't have to be. Just remember to include the essentials, like your ID, medications, and a change of clothes, as well as some snacks and entertainment. And if you have room, consider packing some headphones, a travel pillow, chargers, toiletries, and a jacket or sweater. By being prepared and packing smart, you'll be able to enjoy your flight and arrive at your destination feeling refreshed and ready to go. Happy travels!
