Q&A for How to Change Planes for a Connecting Flight

You could, but I would advise you not to. If you leave the airport, you will have to go back through security on reentry and there's no way of knowing how long that process will take.

You can ask for help at the airport. There are people appointed to help the travelers have a hassle-free journey.

The answer to this will depend on whether or not these two terminals for different airlines are connected directly via an interior hallway (e.g., Albany (NY) International Airport) or if you will need to exit the one terminal and enter the other because there is no connecting hallway (such as at Los Angeles International or John F Kennedy International Airport). If there is a hallway that connects the terminals, you won't have to pass out of one and pass into the other. However, if they don't you'll be forced to pass out of one and into the other, through the Security checkpoint. Check with staff there, if you are unsure to see if they have other methods for getting there.

No, they wouldn't. Normally if changing flights, you would just get off the plane and then be able to have a meal and stuff. That is how it is with most layovers. As long as you don't leave the airport, security shouldn't be a problem.

Usually the airline will take care of transferring your checked luggage from one flight to the other, so you wouldn't have to worry about doing that if you check it. It's really just about your personal preference and your bag size. You will have to lug it around the airport if you carry-on, but you might prefer to keep it with you. Both options are relatively stress-free, it's your choice.

Most airlines deliver checked baggage to the final destination instead of making it available during connections. If flying with a smaller airline, it might be best to check with them on where your baggage is going, which you can do when checking your luggage or at the gate.

Usually not unless you leave the airport, or the portion of the airport past the security checkpoint. Usually the boundaries of these areas are clearly marked. On international flights, an additional security check will be necessary on most occasions.

As long as you can explain your reasoning to airport personnel and security and can be civil with your conduct while waiting for this plane, most will be happy to allow you to stay behind inside the airport to wait out until your next airline trip that following morning. However, if the airport closes at any stage during the night, you will need to find accommodation and return the next morning.

Philadelphia supplies a bus that goes from Terminal F to Terminal B/C, take that and you don't have to go outside security. If you need additional help or information, just ask anyone on staff at the airport, they should be able to help you.

Usually not, but it depends on the flight times and any potential changes in the schedule.

You will go through Paris for immigration. You most likely won't have to go through it in Munich.

Most likely, as the planes should be located in the same terminal.

No, since you'll already be in the terminal. You will need to walk off one plane and find where the connecting flight is boarding, and then wait for it to board. You won't have to wait in line and go through security again.

Not always. You usually will only go through immigration at your final destination, not for connecting flights.

It is more usual for an Unaccompanied Minor (UM). Sometimes they do it though.

Some flights in other countries may have you check the bags again, but they don't usually make you do it.

You can use your cell phone as long as it is set to airplane mode.

You can search online for the map of the Copenhagen airport and plan out your route. If you have a layover, you will probably have more than enough time to locate your gate. Many people there will speak English, so you can always ask for help once there if necessary.

Ask for an interpreter. It's usually free, and can be a huge help. Or, get the Google Translate app. It may be a little stinted and odd, but it might help you get the information you need faster. Also, don't be afraid to talk to those around you. They may speak the language you need and can possibly help you if they're not rushing.

It depends on the country, but usually, yes.

You will have to pick it up at the connection, and then you will have to check it again at the next gate.

The time that is normally required between flights would be one to two hours, but sometimes it could be more than that depending on your flight tickets.

Some airports do, some don't. If you have trouble understanding where you need to go, you should have no trouble finding an employee that speaks English that can help you.

The north-south shuttle at Seattle airport will most likely be air-side, but sometimes it changes to land-side, depending on the flight and where you're flying.

It depends on the size of the airport and if you think you'll have to change terminals. Generally an hour is the minimum.

No, but you could likely check into both flights online before arriving to the first airport.

If you already bought the tickets, then don't. But, if you didn't buy it yet, then do it!

Luggage will transfer to Quebec. You will go through customs upon landing in Quebec, not on your exit from the United States.

You don't if you are flying with the same airline. However, if you fly with 2 different airlines, then you probably will. Note that if you print the boarding ticket at home, you may have two passes.
