While all four local airlines – Cathay Pacific Airways, its budget unit HK Express, Greater Bay Airlines and Hong Kong Airlines – will have to follow the new rules, they can also make their own arrangements within the boundaries of the requirements.

The Post breaks down the details of the tightened rules.

1. Can passengers bring power banks on board?

The Civil Aviation Department on Monday said it would ban passengers of local airlines from using their power banks to charge any electronic devices or charging the batteries on board flights.

Travellers will also be prohibited from storing power banks in the overhead compartments.

This means passengers will need to keep power banks on them, or place the batteries in the seat pocket in front of them or in their hand luggage under the seat.

The new rules will take effect on April 7.
