When flying internationally, understanding baggage rules is crucial to avoid unexpected fees or delays. Key regulations include weight limits, typically around 50 pounds (23 kg) for checked bags and 15-20 pounds (7-9 kg) for carry-ons. Be aware of liquid restrictions—containers must be 3.4 ounces (100 ml) or less and fit in a clear, quart-sized bag. Some items, like sharp objects and large electronics, may need special handling or are prohibited. Check your airline's specific policies before packing. To avoid hassles, pack light, use TSA-approved locks, and label your bags clearly. Planning ahead ensures a smoother travel experience.
