John Wayne Airport in Orange County has a set of guidelines for travellers to follow when it comes to bringing food and other items through airport security.

Medication is allowed in carry-on baggage
The Transportation Security Administration (TSA) allows passengers to bring prescription drugs and other medically required liquids, such as water or juice, through security and onto flights. Medically necessary liquids that cannot be opened or X-rayed will still be allowed, but you will probably have to undergo a pat-down screening, so it is advised to arrive at the airport early.
Liquid medications must be in 3.4-ounce (100ml) bottles and placed in a one-quart-size clear zip-top plastic bag, along with other personal liquid and gel items.

This includes devices such as laptops, cell phones, tablets, electronic toothbrushes, and other rechargeable items. These items must be kept in carry-on baggage or with the passenger in the cabin.

The FAA data shows that such incidents occur on average of two flights each week.

- Spare lithium batteries are only allowed in carry-on baggage. They must be in their original packaging or have their terminals covered with non-conductive tape.
- Some airlines, like Southwest, have policies regarding the use of portable chargers during the flight. They must remain in plain sight, and charging devices in the overhead bins is prohibited.
- Protect your electronic devices with a sleeve or case to prevent damage to the battery during travel.
- Always turn off electronic devices when not in use to prevent overheating or other issues.
- If your device overheats, smokes, or ignites, notify a crew member immediately. They are trained to handle such situations and have the necessary equipment.
