The UK Civil Aviation Authority has issued a warning to passengers about the dangers of incorrectly packed lithium batteries on flights, urging travellers to carry these items in the cabin.

As the summer travel season kicks off, with over 60 million people expected to fly, the regulator is emphasising the importance of packing items like mobile phones, vapes, and power banks in carry-on luggage to prevent potential fire hazards.

The campaign, launched in collaboration with airlines and airports, aims to raise awareness about the risks associated with everyday electronic items when packed in checked baggage. Giancarlo Buono, Director of Aviation Safety at the UK Civil Aviation Authority, stated, “Flying is by far the safest way to travel and we want to keep it that way. Pack right for a safe flight, and that means don’t put your batteries in your checked bag.”

Recent data highlights the urgency of this warning, with incidents involving lithium batteries occurring approximately twice a week. Reports of overheating or malfunctioning devices nearly doubled between 2024 and 2025, with a 91% increase in cases of incorrectly packed devices in checked baggage. Despite this, awareness remains low, with 36% of travellers unaware of the dangers.

The UK Civil Aviation Authority stresses that power banks and vapes are particularly high-risk and should always be carried in the cabin. Passengers are advised not to charge power banks during flights and to consult airline guidelines for specific rules. As the summer rush begins, the authority's campaign seeks to ensure passenger safety and minimise risks associated with lithium batteries on flights
