Is it possible to visit the cockpit after the plane arrives? (commercial flight only)

For the airline I work for rules simply say "passengers are not allowed to enter the cockpit at all times" and this is the rules for most (if not all) airlines, but out of personal experience as a cabin crew member this is not something unusual to happen after landings, especially for younger ones. After all the captain is in charge and can break the rules.

Anyway, keep in mind the following if you are to ask for the same:

• NEVER ask during the flight, or before departure. A simple misunderstanding by the crew can lead to bad situations.
• Ask the crew after landing, it is better to ask the cabin in charge (purser) while you leaving, they are always positioned at the forward part of the plane and usually next to the forward most deplaning door.
• If you are seated in a seat with a good view of the cockpit door, do not deplane and wait until you spot one of the pilots getting ready to leave the plane, then move. Approach with a smile and ask if it's possible to take a photo inside the cockpit. Sometimes cabin crew tells you it is not allowed without asking the pilots.
• If you get a no as an answer, say thank you and leave. Do not argue.

For those who wonder what might be the risk of letting someone enters the cockpit after landing? well, people can always put "something" there. So, if you were allowed by the pilots to take a photo inside, do not expect to spend time there, it will be just a quick photo with the presence of the pilot(s).

I am young - but my body is rather old. I still find it interesting to look at and take photos of cockpits (and just about everything else).

As I invariably travel cattle-class I often get to the exit near the cockpit too late, but when circumstances allow, after the flight, I occasionally ask if I may visit the cockpit. I've done this maybe 5 to 10 times in recent years & I have been permitted to on all occasions bar one (and I think that that was not the pilot's decision). Once there I ask if I may take photos and on every occasion I have been allowed to.

Crew sometimes pose in their seats for the photos and sometimes move aside leaving a person free view.

Flights have been either NZ-Australia, NZ-Asia or (less common) Asia internal. Airlines have been a cross section of those who fly those routes.

When any of the photos surface I'll post one or two here.

4 years later (August 2015) - here's one from my wanderings.
Not marvellous as photos go, but the fun of the moment is the point. I imagine they are not too keen to be posed and arranged etc.

The one below is not one of mine, alas :-) - this is a view in and from "White Knight".

There is no law that forbids you access to the flight deck in the US or most elsewhere in the world after the flight is completed. The only thing that prohibits you from doing so is policies of individual companies or the decision by the Flight Attendants or Flight Crew.

There are many questions on the interwebs related to the subject but the most recent one I was able to find as a reference:

• Captain Lim

I was young and in flight my father asked the flight attendants if I could see the cabin. I got inside and one pilot even let me control the plane with a lever or something and it bumped a little. I was like 6 years old and it was a really cool experience. So it depends mostly on how friendly pilots and flight attendats are. Just ask them.

I was twelve when this happened, but our plane SYD-PER was delayed getting to the gate, so i started talking to the pilot. He was very nice and we were just talking about the best and cheapest way to get a pilot license, when the plane came in. As i said goodbye so the pilots could board, he turned around and said, "If you stay last on the plane, you can come up and see us in the cockpit. The flight attendant came and got us, and i got to take some photos and have a look around, including sitting in the seat of the pilot. I never asked, but being polite can get you places.
