I'm new to A.net and this is my first post, but I've been reading the forums and checking out photos for a couple years now. Finally scraped up the cash and decided to become a member since the material posted on this site is, I think, of very high quality.
Here's my first .02:
I think cockpit crew members serving drinks in the cabin or simply meeting and greeting in flight is appropriate under some circumstances, such as longhaul day flights more than 5 hours or so on a widebody aircraft. I'm not sure of the FARs that govern such activity though, so I won't be too assertive.
First, I think it's a great gesture of customer service that one probably would expect during the more "grand" days of air travel in the past (back when you'd find bars on 747s...). Giving pax a chance to interact with the captain or F/O would really make a great impression on me, personally. Young kids would like it too of course. It also kind of reminds me of old traditions on ocean liners crossing the Atlantic when some lucky pax would have dinner and a champagne toast with the captain of the ship. Such gestures I think would really stand out with some pax and cause them to keep flying whatever airline it is... but then there are those like that jerk in the suit in The Langoliers who could care less about anything but getting where they want to go.
Second, I think it would be a good "break" for one of the flight crew from the monotony of watching the autopilot and working radios. Taking a 10-15 minute walk through the cabin to chat for a bit while somewhere over the North Atlantic must be pretty refreshing and rejuvenating before making landfall.
I'm pretty sure you won't see this too often on U.S. carriers after seeing (and reading about) a lot of crew members who seem to not be too thrilled about their jobs. And the TSA
probably frowns upon it too. Oh well. Good job KLM!
