What the dataset shows
ULSE analyzed incident information voluntarily shared by more than 40 airlines. The weekly average reached 2.36 incidents in 2025, compared with 2.05 in 2024.
Portable chargers move to the top
The report says portable chargers overtook e-cigarettes as the leading device involved in reported incidents. It links the issue to thermal-runaway risk and gaps in passenger awareness.
Read the limits with the findings
ULSE notes that the incident data covers only participating airlines and is not normalized by airline participation or miles flown. The numbers describe the program dataset and should not be presented as a complete global incident count.
