Transporting liquids, including culinary oils, on international flights is subject to regulations imposed by both individual airlines and international security bodies. These regulations primarily center around container size and the total volume of liquids permitted in carry-on baggage. Typically, containers must hold no more than 100 milliliters (3.4 ounces) and be placed in a single, transparent, resealable plastic bag. Larger quantities are generally permitted in checked luggage, though individual airline restrictions should always be consulted.
Understanding these restrictions is crucial for smooth and efficient passage through airport security checkpoints. Adherence prevents confiscation of items and avoids delays for both the individual traveler and fellow passengers. Historically, these regulations evolved in response to security concerns, striking a balance between passenger convenience and the imperative to maintain safe air travel. This reflects the broader context of international air travel security measures that have become increasingly standardized over time.
