To avoid booking flights with tight connections, try to travel with only a carry-on bag and avoid checking in any luggage. This way, you can save time and money on baggage fees, skip the baggage claim area, and avoid the risk of losing your luggage or having it delayed or damaged. When packing, make sure to check the size and weight limits for your carry-on bag and personal item on each airline and airport. Pack only the essentials and use packing cubes, compression bags, or vacuum bags to maximize space and organize your belongings. Additionally, pack liquids, gels, aerosols, and other items that might trigger security alerts in a clear plastic bag and place it on top of your carry-on bag for easy access. Lastly, pack a change of clothes, some toiletries, a snack, a water bottle, and any medications or valuables in your personal item in case your carry-on bag gets lost or delayed.
