Such a shame, I had two really enjoyable jump seats rides with Buzz to and from Berlin some time ago. Two really great Captains, and my only time on the 146. I enjoyed flying Buzz.
Whilst I respect 'moleslayers' views, and I'm sure they are correct, VFE, I suggest you ask anyway.
I was returning from India recently, (early December) and wasn't planning to ask. However, when a quiet moment presented itself I thought I'd give it a try. 20 minutes later I was on the flight deck.
The cabin crew and the flight crew both told me it shouldn't be happening, but they were all sick to death of the situation being as it is now, and the Captains justification was along the lines of "I've been flying for 30 years, I think I can tell the difference between an interested PPL and a terrosist...."
On the down side, I was told by the No.1 that she thought I had been lucky enough to get "one of the only Captains in the company who still will..." , I was very lucky, and I was the only passenger she had seen on the flightdeck since 11/9.
VFE, ask, they can only say no!
PS: Are you going to the Gatbash mate, I am, so I'll see you again if so...
(Don't worry - airline and aircraft type all witheld so as not to incriminate anyone!)
