When packing a carry-on bag for a flight, its important to consider the airlines size and weight restrictions, as well as TSA guidelines for liquids and gels. Here are some items that are commonly recommended to pack in a carry-on bag:

• Identification documents: Passport, drivers license, and any other necessary travel documents.
• Phone and charger: Keep your phone and charger in your carry-on bag so you can stay connected during your flight.
• Headphones and electronics: Bring headphones to listen to music or watch in-flight entertainment. You may also want to bring a tablet or laptop to work or watch movies.
• Change of clothes: Pack a change of clothes in your carry-on in case your baggage gets delayed.
• Reusable water bottle: Bring an empty reusable water bottle to fill up after passing through airport security.
• Snacks: Pack some snacks in case your flight is delayed or you get hungry during the flight.
• Prescription medications: Pack any prescriptions into your carry-on luggage along with any over-the-counter medications you take frequently or might need, such as pain relievers or allergy medicine.
• Toiletries: Pack a toiletry bag with travel-size liquids, including shampoo, lotion, liquid makeup items, and hand sanitizer. Make sure to follow TSA guidelines for liquids and gels.
• Compression socks: Compression socks can help improve blood flow during long flights.
• Small tote bag: Pack a small tote bag and toiletries bags within your carry-on luggage to help keep items organized.

Its important to note that some items are prohibited on all flights, due to Federal Aviation Administration regulations. The prohibited list includes aerosol products, lithium or lithium-ion batteries, firearms and ammunition, flammables, and explosives. Toiletries and clothes can go in the checked bag, but most airline terms of service recommend not packing anything valuable in checked luggage, as things can go missing.
