I've heard conflicting news stories and hearsay regarding the topic: Can I take a laptop (and also a digital SLR camera with a lithium rechargeable battery) as carry-on luggage on a flight from mainland Europe to the US? Is this policy expected to change in the next few weeks?
Q1: Yes. This isn't really in question. Laptops and Lithium batteries are allowed (sometimes required) as carry-ons. You will have to check with the airline you are flying as each airline and/or regulatory authority can have slightly different rules.
Q2: Sorry, this question cannot be answered. My estimation though is no. We will only know for sure when a change is announced. Update: That Answer is now NO because no change has been announced. However, it can happen at any time, though unlikely.
