Regardless if you are a Captain/FO/SO/FA, rules have changed and I'm happy with them. CA's, forget the days you can bring your family aboard, get with the real time, cant believe you think that is still ok. A simple blanket rule is NO FLIGHT DECK access. These rules are in place for your protection, not any one elses. Remember that. Think about where you work and think about how many lives are in your hand. Think about kids that shoot kids. No not your child, but access to the cockpit is suicide. Think about Colombine, and all the disasters that have happened, no not your kid but anyone can bring a plane down, thats why we have NO ACCESS. If you were my captain I would be very concerned if your kids were up on deck. 30 years ago I wouldn't have a problem but now, no way.
