Visiting higher/lower cabins during a flight. What's the etiquette?
 

[edited]

Anyway, I'll be traveling in first and my friend will be traveling economy. My question is, what's the etiquette in me visiting him in economy during the flight? I wouldn't be smuggling first class food or anything but just a quick chat during a long haul flight to break up the time

Premium economy is maybe the BMW 328i, but I'd say economy plus is a Honda Accord, and economy is a Honda Civic. Almost the same car, a little more legroom in the E+. :)

I was in F on a flight ORD-DEL and went back to J to visit a friend. The FAs were polite but made it clear I shouldn't stay long. Visitors get in their way. If you really want to be with your friend, then you should either get him upgraded or suffer in economy yourself.

Me, I'd wish a pleasant goodbye to my friend at the gate and catch up with him several hours later. :)

I like my Accord a hell of a lot more than E or E+.

Travelled in J while friends in economy. I didn't feel the need to have to see them for 3 hours.

Let's keep it to one manufacturer!

First: S-Class
Business: E-Class
Premium Economy: CLA-Class (skipped C-Class, too nice these days)
Basic Economy: Sprinter Van

Wrong answers. Don't trust what some anonymous expert says on FT

You can do ANYTHING you want on ANY flight as long as the crew says it's OK. Just ask first, and they say"fine", then do it. But if they say "no," then there's your answer. It's that easy.

And be considerate. Don't block the aisle and don't disturb other passengers.

The etiquette (and in some places the actual law) is that you can go only down from your class of travel, save for having permission from the crew to do otherwise.

I.e., without asking the crew, you can visit your friend but he can't visit you.

A quirky rule since everyone has to go through the same security procedures to get on to a plane heading to the US.

There is no plan for him to visit me because we've all seen Bridesmaids :D But for 14+ hour flight, a little chat in steerage would a nice break

I don't see why people can't just remain in their own cabin. People moving around inflight in general is annoying. We all need to do the basics - use the loo, etc. - but extraneous wandering between cabins is a nuisance to the crew and other passengers.

My wife and I travel in separate cabins a lot. (If you've ever noticed vastly different search results when you search 1F vs 2F across an entire alliance, you know why.) We've never failed to locate each other in the gate area upon arrival.

Being considerate goes along with the crew

This.

Fidgety adults are annoying, and I am willing to bet most of the visitations in the higher classes are far from critical. The f or c pax should go back to coach if they need to speak so only those with tickets for f and c are in those cabins.

The thread's title is about etiquette.
I'd suggest that good manners dictate what ought to be done in consideration of others, rather that doing something just because you can.
