What this really means is that it puts it in line with the US regulations that allow you one piece of hand luggage and a personal item like a laptop.
For the simple sake of being able to have two small pieces through security is happiness for me.
But it's also subject to individual airlines, which will cause confusion.
most definitely, but this should be taken up with the airline and not necessarily the airport security people as you go through x-ray. That is where the problems will arise if this staff start monitoring passengers' luggage and airlines.
Virgin allows 6kgs only and easyJet as much as you can manage without assistance within the baggage restriction. Differences are vast!
