Airport and immigration, from check-in to clearing the border

Risposta rapida

  • At an international airport the usual order is: check in or drop bags, pass security, clear outbound immigration, wait at the gate, and on arrival pass immigration, collect bags and go through customs. Recommended arrival times and baggage limits differ by airline, so use your ticket email and the airline and airport websites.
  • Immigration wants direct answers consistent with your documents. Keep your accommodation confirmation and return or onward ticket to hand, and answer truthfully and politely.

Overview of the departure airport steps

  1. 1Arrive when your airline recommendsRead the recommended time and counter-closing time from your ticket email and the airline and airport websites. Peak seasons and large airports often take longer, so do not treat a generic figure as a rule.
  2. 2Check in and drop bagsYou can check in online when the airline opens it, then go to bag drop. If you have no checked bag you can go to security, per the airline's policy. Make sure you receive boarding passes for every flight segment.
  3. 3Pass security screeningPrepare liquids and electronics as the airport requires, take out items that need separate screening, and keep your boarding pass and passport easy to reach.
  4. 4Clear outbound immigrationHand over your passport and boarding pass as requested. Specific procedures, such as automated gates, depend on the airport.
  5. 5Go to the gate and check the screensGates can change, so check the information screens and your airline's app or email periodically, and reach the gate before the time on your boarding pass.

What cannot go in the cabin or hold: how to check

For questions like which items are banned from the cabin or hold, or how much liquid you can carry, there is no number that applies everywhere. Airport, airline and destination rules combine and can change. Read the restricted-items pages on the airline and airport websites at both ends, and if unsure, ask the airline before you pack.

Power banks and lithium batteries have airline-specific rules. They usually have to travel in the cabin rather than in checked bags, but confirm the details with your airline. See our article on power bank rules on a plane.

Passing immigration abroad: what the officer is doing

On arrival, immigration checks whether you may enter, looking at your passport, visa or approval, and may ask a few short questions about your purpose of travel. Some countries use automated gates or take fingerprints and a photo. Most travellers are asked few questions or none, but you should be prepared.

What immigration may ask, and how to answer

Questions usually fall into four topics: the purpose of your trip, how long you will stay, where you will stay, and your return or onward ticket. The key principle is to answer truthfully, keep answers short and consistent with the documents you carry, and have the relevant papers close at hand.

ArgomentoSample questionPolite sample answer
ScopoWhat is the purpose of your visit?I'm here for tourism. (if that is true)
Length of stayHow long will you stay?I'll stay for [your number of days], and I fly home on [date].
AccommodationWhere are you staying?I'm staying at [hotel name]. I have the booking here.
Return ticketDo you have a return ticket?Yes, I do. Here is my itinerary.
Use these only as a guide and fill in your own facts. Do not memorise answers that do not match your documents. If you do not understand, you can politely ask the officer to repeat, for example: Could you repeat that, please? Procedures and outcomes are the officer's decision, and this article cannot guarantee any result.

Forms: arrival card, departure card and customs declaration

Some countries have an arrival card, a departure card or a customs declaration, on paper during the flight or online before travel. These systems change often: some have dropped paper, others have added online systems. Check the immigration or customs authority's official website, not a site offering to fill it in for you for a fee, which may not be official.

  • Carry a pen and your accommodation details ready to fill in
  • Fill it in truthfully and consistently with your documents
  • Customs has country-specific rules on goods to declare or banned imports; check the destination customs website before you travel

Connecting flights: layover versus stopover

A flight connection means changing planes on the way to your destination. A layover usually means a short wait between two flights, while a stopover usually means a longer break, sometimes with time outside the airport. The exact meaning depends on the airline, so read your ticket conditions.

A common question is whether you must clear immigration and collect bags on a connection. It depends on whether the tickets were issued as one booking or separately, the connecting country and the airline. With a single ticket your bags can often be checked through to the final destination, while separate tickets usually mean collecting bags and checking in again, which may involve immigration. Confirm with the airline at check-in and allow enough time.

If you want to be online while waiting for a connection, see our layover and transit data article, which explains the options without relying on numbers that can change.

Staying online at the airport: boarding pass, maps and messages

Having internet from the moment you step into the destination airport lets you call a ride, open maps and open your accommodation confirmation email, which immigration may ask to see. Airport Wi-Fi may work, but keep a backup. A travel eSIM installed before you fly is one option. Check your phone supports it before buying, and check the live price at purchase.

FAQ

Go to the airline's website or app, enter your booking reference and surname, choose a seat and save the boarding pass. When check-in opens depends on the airline, so read your confirmation email.

What are the carry-on and checked baggage weight limits?+

No fixed figure is given here because airlines and airports differ and rules change. Check the airline and both airports' websites before you pack.
