When I was young (before 9/11, I was 12 or so) the pilot crew of my EasyJet flight from Amsterdam to Geneva invited me to the cockpit to see. I was flying with my grandma and it was my first flight ever. I love flying and the machines, being in the cockpit as a 12 year old boy was so staggering and inmense.
Then I didn't fly for years, and about a year ago (while being 24) I started traveling more. Suddenly while being delayed at Amsterdam airport the cockpit crew of my EasyJet flight to Split invited people to the cockpit if they wanted to see. I waited 2 minutes to see if any children would come up and then decided to relive my childhood memory and go to the cockpit.
Another time while on a KLM flight to Bangkok I gave the cabin crew a bag of chocolates as a thank you gift for the good service. I did the same thing when flying back from Bangkok to Amsterdam as a thank you to get me home during the pandemic (this was end of march). Both of the times they personally thanked me, the first time I even got one of the little houses they give away to business class passengers [0].
My point is, those human moments do exist. It is just that most people don't 'want' them anymore because that means that it should come from themselves. (No one was standing up to go to the cockpit, nor was anyone else giving candy to the cabin crew). I am sure something changed after 9/11, things like being in the cockpit while flying isn't an option anymore. But with what is going on these days, I can't complain about that.
I have to admit, maybe I am a bit biased. If it weren't for my small stutter in intense situations I would've probably been a pilot. :-)
