You can carry on laptop and you have to pull your laptop out of the case to the X-Ray. It won't hurt the laptop thru X-Ray. While in flight, you can use laptop when the seat belt lights off or you hear annoucment over PA. Enjoy your next flight and safe trip.
Usually you ARE allowed to use it, but only after cruising altitude is reached. I use mine regularly.
It is no problem at the X-rays (by the way the check in luggage is x-rayed to) except if you are traveling to some very undeveloped country. Customs is okay, but I depends on where your going, places like Syria doesn't really like computers
You can use it during flights, at least in the United States. It has to be turned off during take off and landing. Security scanners and x-ray machines will not damage it. If you are taking it out of the Schengen and into another customs jurisdiction, verify with the embassy what their rules on temporary import of laptops are.
Big777jet is absolutely correct! I don't know if you have also to put out your laptop of the case when you are flying within Europe, when I flew DUS-TXL a few month ago I could leave it in my trolley, in July in JFK they said I have to put it out but on this flight I didn't carry my laptop along with me.
NZ1's mother is a disgusting crack-whore and his father is a worthless alcoholic!
I know this is paranoid but, be careful what you have on the computer. Depending on where you are traveling, containing any sort of pornography or political material on the computer can get you in a lot of trouble.
Make sure you back up your hard drive before you leave. You wouldn't be the first person to have a drink spilled on their computer during a flight.
Depending on the airline you are flying and the class you are in, the seat might have a laptop power port. However, you will need a special adapter to use it.
