My Daughter will be flying alone from Athens, Greece to Chicago with a layover in Newark. What exactly will she have to do during her layover in Newark?

Specifically, will she have to:

  • Go through customs?
  • Immigration again?
  • Claim checked bags and recheck them?
  • Go through security again?
  • Anything else?

I have heard something about having to go to a "flight connections" counter after she lands in Newark and she's not allowed to get on the 2nd flight without checking in there?

    Welcome to TSE. Some additional details could make answers more helpful: is your daughter a minor? What passport will she be traveling on? Is the itinerary on a single ticket, and which airlines are operating the ATH-EWR and EWR-CHI segments?

    The two largest factors here are going to be age and airlines. There are certain programs that cater to children of different ages. Some of these differ based on age and many of them have requirements like all flights in the same airline. There may also be extra documents depending on age. For examples minors should travel with a "Letter of Authorization" or some such.

    If your daughter is Greek, how good is her English? Once in the US, she will find relatively few Greek speakers to help her out if she needs some assistance.

  • The odds of finding a Greek speaker go up considerably in Chicago.

    Is your daughter Greek, US citizen, EU citizen, or anything else? Is she 25, 19, 17 or four years old? That will make a huge difference.

There's a bunch of confusion here still, so I'll try to lay out all the steps in more detail.

One note first. Airlines offer an "unaccompanied minors" service, where airline employees will escort your daughter from the time you drop her off to the time she is picked up by an authorized adult. This service is mandatory for children 15 and under on United (which is utterly insane, but I digress), but the policy varies from airline-to-airline. Not all airlines offer this service, and it isn't available on all itineraries, so if your daughter is young, you'll want to check with the airline to ensure she actually can fly alone.

Before traveling

  • Ensure your daughter has an ESTA or a US visa if one is required. If she is a US citizen, she needs a US passport to enter the US. If she's a Greek citizen (and not a US citizen), she can travel to the US for up to 90 days on the Visa Waiver Program, but needs to complete the online ESTA form first and pay the $14 fee.

Athens Airport

  • Arrive at the airport. Drop off checked luggage at the counter and receive a boarding pass if you haven't obtained one online already.
  • Proceed through the security checkpoint
  • Go through the Greek exit immigration check
  • Go to the gate, wait for boarding, and board the plane at the appropriate time


  • While on the plane, she'll be given a customs declaration form. She'll need this filled out when she arrives at US immigration.


  • Exit the plane and follow the hallways to the immigration area
  • Follow the signs depending on whether she is a US citizen or not to the immigration line. There will be people around to ask questions if she is unsure where to go.
  • Go through immigration (also called "passport control")
  • Continue to the baggage claim (TV monitors will indicate which baggage claim is serving the flight she arrived on). Pick up checked luggage. There should be luggage carts available in this area.
  • Take the bags through US Customs, giving them the declaration form completed earlier.
  • Go to the baggage drop for transfer passengers (there will be signs). Give them back the checked bags.
  • Follow the signs for connecting flights. Depending on the terminal and exactly when the flight arrives, it is possible that she will have to change terminals in Newark. It is also possible that she will not. Either way, there will be TV monitors that list the gate assignments for flights and uniformed staff to help provide directions.
  • Go through TSA aviation security
  • Walk to the gate, wait for boarding, and board the plane at the appropriate time


  • Get off the plane. Follow the signs to baggage claim
  • Check the monitors to find the right baggage claim for the flight
  • Claim baggage
  • Exit the airport (no immigration, no customs)

    I think it's insane to think that a 15 year old can't survive a fight on an airplane with out their own personal baby sitter. Sure there are some 15 year olds that can't and the service is great for them, but there are many that can, and making them have their own personal baby sitter for the length of their journey is silly.

    @Gusdor It's a very heavyhanded service calibrated to the needs of the youngest passengers in the allowed age brackets who can't be trusted to find their way through the airport without escort or be trusted not to wander off after getting to the gate. Many teens would find it oppressively overbearing. travel.stackexchange.com/questions/72808/… travel.stackexchange.com/questions/48291/… Commented Jul 28, 2016 at 13:48

    Or, as I've seen noted in several articles, 15 year olds are legally allowed to fly their own planes solo in the United States, but UA thinks they all need a flight attendant to escort them around the airport. Commented Jul 28, 2016 at 18:54

All international arrivals to the US work the same:

  • You first go through immigration.
  • Then you claim your bags from baggage claim.
  • You take your bag through customs and make any necessary declarations.
  • Immediately past customs you drop your baggage for your connecting flight.

You only need to talk to someone at the transfer desk if you haven't got the boarding pass for your connecting flight (or if you are delayed in immigration/customs and miss the flight). If you already have the boarding pass, you can go straight to your gate.

  • ok, just to confirm -- so even though she will be going through customs in Athens, I was told, she will also do the same in Newark then? AND have to pick up her checked baggage from the first United flight at baggage claim and carry to the next United domestic terminal next door and go through customs again, correct? Can you believe, that in two separate phone calls to United they told me the direct opposite? I'm so frustrated right now ...

  • @DGaulon In Newark whether or not one needs to change terminals depends on the airline and arrival terminal. But there is a transfer desk in each terminal that should handle her bags irrespective on whether a flight to Chicago leaves from the same terminal or not.

  • ok, I WAS told by United that she does change terminals from international B terminal to C domestic in Newark - but United rep totally misinformed me about the part re: baggage and customs! THANKS SO MUCH

    @DGaulon: Be careful to distinguish between "immigration" and "customs". Immigration involves checking your passport and visas to see whether you can enter the country. Customs checks your luggage to see if you are bringing anything that is forbidden or taxed. AFAIK she would only do customs once. I would not think she would go through customs in Athens at all. Commented Jul 27, 2016 at 21:47
  • @DGaulon In Athens, she will be going through exit immigration formalities. As for baggage, provided she drops it at the drop immediately past customs, it will get to the right place. Commented Jul 27, 2016 at 21:48

I am going to add this as an answer, but it's only a partial one.

Depending on age and other factors your daughter may qualify for "unsupervised minor" treatment. The programs vary a lot depending on age and needs, and it's up to you and the airline to work out the details, but essentially it falls into two categories.

If she is "very young" then she wears a sticker and is assigned a "guardian" from the airline. This flight attendant (usually) will stick with her the entire length of the flight, will give her special attention, will help her though customs and any security checkpoints, and so on. This is basically a baby sitter. On connecting flight they walk the child through the airport and all security "stuff" to their connecting flight. They may hand off the child to a flight attendant on the next leg of the trip.

If she is "young" then she wears a sticker, and special accommodations are made (these apply to very young as well). Most notably she is put on a list and the connecting flights are not allowed to leave without her. Her seat can't be "bumped" and if she gets "stuck" in security the plane has to wait. The security and immigration/customs etc. people are aware of the sticker's meaning and will go out of their way to make the process smooth for her.

It may be worth while (especially if she is under 18) to speak with the airline about these programs. Usually they are called "Unaccompanied minor" or "Young Traveler" programs. Signing up for these will also let you bypass security and pick her up at the terminal, instead of having to wait at the airport exit/baggage claim.

Now, I am saying all this, but make the realization that these programs started "back in a time" when minors traveling on an airplane alone was no big deal. I remember using these when I was as young as 6 or 7. These days people are likely to scream bloody murder if you have a 6 or 7 year old travel alone. Because of that these programs are not as popular as they once were. Also international flights are a bit different then domestic flights and I realize that, but don't be afraid to use these programs. You may be met with a bit of "Oh my god, I can't believe that a parent would let a child travel alone! What a horrible parent." Just power through that nonsense and talk with the airline. They do have a plan and system in place for these types of things, and they really are good at it.

Be aware that there is a cut off for non-direct flights, and there is usually a fee. Unaccompanied minor status is usually valid till they are 18 upon request and usually a requirement until they are 16.

There are some restrictions depending on airline. For example:

    +1 for the comments about letting a young child travel alone! I flew many times by myself when I was under 10, as well, got great treatments from the flight staff & was dropped off at the departure gate by my parents and met at the arrival gate by my grandparents with no trouble. Of course, they used to let non-ticketed people all the way to the gate back then, too...
