Question about travelling- what do you do when get off the plane and arrive at the next airport?

Okay, so basically, I'd like to know that if you need to catch two planes to arrive at your destination, what do you do when you arrive at the second airport? A few dot points in order of events would be really helpful! What I'd like to know is, what happens first when you get off the plane? How do you find your way to the place where you have to hand in the form you fill out on the plane. And if you have no baggage to collect (which a person wouldn't have to since it's not their destination), how do you find your way to the place where you check in to get the ticket for your next flight? Are people usually given both tickets when they arrive at their own country's airport, or will you have to pick up a ticket for the connecting flight at the next destination? Do you check in where everyone else checks in, because I know that the area where people land is in a separate part of the airport than for travellers who are catching their first flight from that destination.

Sorry, I know these questions might sound stupid, but I don't know where to find these answers. Everyone just seems to… Know what to do. I want to plan a trip overseas, but I'm panicking over where to go if there's a connecting flight and how the whole process works until you arrive at your destination…

Generally, your connecting flight will be at a hub airport which means your airline may have gates on multiple concourse.
Best thing to do is check with the gate agent or the airline info monitors when you get off the first plane. Once you find out the gate, you head on over. You may get lucky and only have to walk a few gates over or you may have to go to another concourse via walking, moving side walk or tram depending on the airport

Usually you'll be given all tickets when you first check in. When you land at the second airport, you check a screen showing the gate where your next flight leaves. There are people along the way to help you with all your questions.

You only fill out a form on the plane if you are entering a different country. If you have to go through Customs at your layover airport (and this varies depending on your ultimate destination and your layover location), then you WILL collect your bag in order to do that, and will be given a chance to recheck it after that. If this is the case, just follow the crowd. Everyone has to do the same thing. Then you will find the gate for your next flight, just as you did at your first airport, and wait for it to board.

But if you are just changing planes, then it's very simple. You should get the boarding pass for your second flight when you check in for the first one. You get off your plane, identify the gate you need for the next one, and head that way. Then you wait until that flight is ready to board.

Clearly: You leave the US and fly to Europe and arrive at London Heathrow. That is your "port of entry". That is where they check your passport and "log you in" to another country. You do NOT need to get your luggage and you do NOT go to customs. You go through immigration. The may ask a couple of questions, they check your passport and stamp it on the back pages. You only do this once. If you change planes again, like flying in the US, you just go to the gate for your next plane. There can be some lines for immigration so get there right away, but the process itself is quick. When you return to the US, you will again go through immigration and they will stamp show you as leaving. Again, you only do this once (unless you leave the secure area in the next airport). When you arrive back in the US, THEN you go through customs. That's where you declare what you bought, if anything, and they may go through your luggage. And then you go home.

Gosh I'm going to from somewhere to some where. Can you give me the exact directions./
NO
As you want to go another country it gets a little more complicated depending from which of the two hundred countries in the world you are changing planes.

You get off your first flight. You can expect to show your travel documents a passport and maybe a visa to officials at the Airport. Depending on Airport/country you may have to claim your luggage and take it past a Customs officer than can search you and your luggage
After that you return it to the Airline for next flight. This can take some time and a good idea to have about 3-4 hours between flights.

You will usually need to again pass a security check before next flight.

In some places a special part of the Airport is set aside and you avoid all this and just go to next flight with the Passport and Customs check at final destination.

!50,000 flights per day MILLIONS of combinations.
6.000 Airlines and about 45,000 Airports
the procedure is not identical for every possible combination you can dream up.

At First check in you can ASK the human what you do at the stop. For YOUR combination of flights.
Just one Airline Two partner Airlines or Two non partner Airlines it makes a difference. For the luggage The last one you claim your luggage and recheck it.usually.

Usually at First check in your baggage tags, and boarding cards are provided for your entire journey.

When you have narrowed down your travel plan to just a few countries and one or two possible stops along the way ask again and you will get a much more specific answer for your flight combination.

YOU ARE NOT EXPECTED TO KNOW EVERYTHING about the details of what you need to do for every possible combination of circumstances.

Travelling on a connecting flight, ie. Booked as a single booking with the sand or affiliated airlines, mostly means you'll need to go through flight connections, there will be signs for that, you may go through immigration and customs, but not necessarily both. Baggage in this instances will often be automatically transferred.

If your travelling on two bookings that are not linked, you may need to land and go through customs and immigration, and collect your luggage if you have an checked items. You would the need to checkin again for the second flight, this could be in the sane terminal, or a different one for large international airports.

Ask a human being at every stage. Airports are full of people who have never flown before, and the staff are used to dealing with all kinds of questions. Just ASK each time you complete one part of the process: "Where do I go next and what do I do there?"

It has changed. You get of the plane. Clear customs again. If switching air lines you need reclaim your baggage again. Then you catch the shuttle or bus to the next terminal. There you need go threw security again. Then to your new gate after rechecking luggage again. Security has got tight on international flights. It varies some air port to airport. China is the worst. If going threw there. On security.
