Why Haven’t More Airlines Tightened Rules Around Lithium Batteries Despite Mounting Safety Concerns?

Key Takeaways

• Air Busan A321 fire traced to overheating power bank.
• IATA introduced stricter power‑bank rules, 160 Wh limit.
• Only Qantas has fully adopted the new IATA standards.
• Emirates already enforces tighter limits than IATA.
• Policy harmonization delayed by regulatory and internal approval cycles.

Summary

In January 2025 an Air Busan Airbus A321 caught fire on the tarmac in Busan after a passenger’s lithium‑ion power bank overheated, injuring seven people. The incident has intensified scrutiny of portable battery safety on aircraft. IATA recently issued new minimum standards that ban in‑flight charging, limit passengers to two power banks under 160 Wh, and require them to stay in the cabin. So far only a few carriers such as Qantas have formally adopted the rules, while others like Emirates have already imposed even stricter limits.

Pulse Analysis

The proliferation of personal electronics has turned lithium‑ion cells into one of the most common hazardous materials aboard commercial aircraft. Over the past decade, dozens of in‑flight fires have been traced to overheating batteries, ranging from smartphones to high‑capacity power banks. While airlines have long prohibited lithium batteries in checked luggage, the shift toward carry‑on usage during boarding and in‑seat charging introduced a new vector for fire risk. Regulators have struggled to keep pace, often reacting only after a high‑profile incident, such as the Air Busan A321 blaze, forces a public safety review.

IATA’s new safety assessment introduced minimum standards: no in‑flight charging, a maximum of two power banks per passenger, placement under the seat or in a pocket, and a 160 Wh capacity cap. Qantas has already matched these rules, while Emirates went further, limiting passengers to one power bank and demanding clear labeling. Most carriers, however, are still reviewing internal policies and awaiting national regulator approval before implementation.

The fragmented regulatory landscape creates operational challenges for airlines that must train crew, update safety manuals, and manage passenger expectations across different jurisdictions. For travelers, the safest approach is to keep power banks within easy reach, monitor temperature, and report any signs of swelling or heat immediately. As the industry moves toward a unified framework, we can expect tighter enforcement, possible redesign of cabin power outlets, and greater collaboration between manufacturers and airlines to certify battery safety. Consistent global standards will reduce fire incidents, protect revenue, and restore confidence in air travel.
