Hand luggage allowance would be a matter for each additional airline, not security. Security will not refuse to let you through because you have 15kg of luggage instead of 10kg, nor because it's in two bags not one.
DP, Where have you been for the last month? There are currently Hand Baggage restrictions in the UK that are ONLY due to imposed security restrictions and NOTHING to do with the airlines......ONE item only at reduced measurements, see below:

Why cant it be like a recent flight I made through Renne? Separate entry/exit for all pilots/aircrew, I showed my licence, photo ID, the nice lady still X-rayed/searched my bags, but was quite happy that I was indeed a pilot and had a leatherman and drinks for the flight. However, waiting for the fuel truck was a different issue.....
I hear some of you say, I had liquids....and even a knife!!
This goes to show that the airport/government security show/farce/brainwash is really working if supposedly inteligent pilots can fall for the fact that the OBJECT is the danger and not the INTENT of the person.
Think about it.
