When flying, what I can take with me on an airplane is a common issue faced by passengers or travelers. So, you can bring a carry-on bag and a personal item, like a purse or laptop bag. Ensure your carry-on fits the airline's size restrictions, usually around 22 x 14 x 9 inches. For liquids, follow the 3-1-1 rule: containers must be 3.4 ounces or less, all fitting in one quart-sized bag. Essential medications, baby food, and formula are exceptions but must be declared at security. Electronics such as laptops and tablets are allowed, but larger devices need to be screened separately. Finally, pack any valuable or essential items in your carry-on to avoid potential loss or damage.
