Dear Sir,

I am going to take a long flight and wonder if there is any way to charge or power a laptop computer during that flight? I am taking Southwest Airlines and am in business class. The aircraft is a 747-400.

Thank you for your assistance

Only advice I can offer is to charge an extra battery for back up and take it on the flight with you.

Check with the airline. Some have outlets installed.

Yes, many airlines do have outlets, but you will need an adapter that can be used with an airline outlet.
