.....and noticed an interesting sign on the Korean Airlines desk. Besides the normal warning about not taking liquids on the plan, it singled out two laptops that have to have their batteries checked or removed in order to bring them on the flight.
Older Mac laptops and ALL Dell laptops. The warning was especially strict for the Dells laptops. It said the the batteries for them cannot be brought on the plane at all. Not sure how handy your laptop will be without it's battery
Not sure if this is just Korean Air, but thought i'd give a heads up to at least call the airline if you have either of those types of laptops.
