Depending on the airport, then I think it all depends on the dispatcher / staff watching the passengers. At military airports or places like Dubai, Saudi Arabia etc then it's obviously a big no-no but in the UK I see no problem.
Personally, I have no issue with any passengers taking pictures on the ramp while boarding / de-boarding my flights as long as they use common sense and don't do anything stupid. For a lot of people, flying is all part of the 'holiday experience' so I see no reason why they can't record that 'moment' on a photo.
Generally, as long as the passenger takes a few quick snaps then continues walking into the terminal building / aircraft then there's no harm. The few times I will say something is when people take it upon themselves to stand in front of the engine (
) or stand at the bottom of the steps while they get some photos, therefore causing a backlog of pax.
I quite often handle football flights and for some reason the Italian / Spanish supporters always seem adamant on getting a photo taken with myself / other ground staff
