I've seen a lot of folks post pictures of themselves and their kids in the cockpit while the plane while on the ground. I'll be flying with my 6-year-old next week, and I think this would be a really cool experience for him.

What is the best practice in terms of making this request? I am assuming that I ask the gate agent about it prior to departure, but I figured I would ask if there are any dos and don'ts I should be aware of.

Thanks!
