Hallo! 😊 In two days I fly to my grandma and stay there for 3 weeks. Can I take my laptop, battery cable, wireless keyboard, mouse and my headset on board? So in hand luggage?
If these items have been examined by the staff and the laptop is set to flight mode, yes
Yes you may.
Make sure that the battery is charged - sometimes they ask randomly at the security to start the device.
Yes you can, you just have to unpack your laptop at the security check and place it separately in a tub.
