Which steps happen before you fly internationally (check-in / boarding)?

The procedure for flying internationally is somewhat involved and any mistakes or omission on your part is considered your fault which can cause delays or loss of your flight, so it is very good to know the steps involved.

1. The first step is usually to check the entry-requirements of your destination country. You need to make sure that your current documentation allows you to travel to your intended destination. This means making sure you have a valid passport that satisfies the entry requirements of the destination. A number of countries ask for a passport to be valid for a certain number of months (3-6 is typical) beyond your arrival.

   Depending on your nationality, you may need a visa to travel where you are going. In this case, you must get informed on how to proceed. Some countries offer a visa-on-arrival but those have requirements too (ex: bringing a photo of a certain size and cash of a certain currently - usually USD to pay for it), some offer electronic visas you can apply for online, some require you visit a consulate and leave your passport there which you can pickup or have it mailed back.

2. The next step is to buy your ticket. Most tickets have set dates and those are the days you will be flying, always in local-time (important to for you return flight and possible connections. Be sure to book sufficiently in advance to have received any documentation you need, including renewing your own passport if it needs to be valid longer than the one you currently have and visas on the passport you will travel with (some visas are assigned to the passport while some are transferable, so be sure to get them in the right order).

   A. When booking you ticket, pay particular attention to stop-overs that are not in the departure or arrival country. They may have Transit Visa requirements depending on the duration of the stop over. Generally, you will need to have the right to enter the country for overnight stop-overs.

   B. If you have an Open Ticket, you will need to call the airline to book the departure date. Those are rare and generally more expensive. Travel vouchers and award travel work similarly.

3. Pack. Verify your baggage allowance which is generally split into a personal item, a piece carry-on luggage and checked luggage. Airlines have strict strictions on most of these but only checked ones are systematically checked. Try not to exceed any official limit as some airlines are quite strict! Be sure that all your essentials (documentations and medicine) plus valuables are in cabin luggage. Be sure to check the allowance for your ticket as airlines sell low-cost tickets without allowance of all types of luggage (but you can usually buy for more at the airport - up to a certain maximum).

4. Online checking. Typical airlines offer online checkin 23 hours ahead of departure. This will allow you to confirm the flight time and date (that may change slightly or a lot - in which case you can call the airline to get rebooked into an alternative you prefer. If not, some jurisdictions allow compensation for significant scheduling changes).

   A. It is possible your online checking will not complete. In this case the process still serves to confirm your flight and often seating and baggage allowance (which you can usually upgrade at that point to) and you will be given a checkin confirmation (usually labelled This is NOT a boarding pass). This will force you to lineup in personal at a checkin counter where they check your entry-requirements to the destination country. Nowadays, they also use this to take a temperature check, asked you questions about covid-19 symptoms and check your paperwork in case you need to show proof of a covid-test.

5. Arrive at the airport with enough time to go through all the following steps. There is usually a limit to when you can drop-off your checked-luggage (typically 1h before departure) and most people go to airports 90mins to 2 hours before departure. Certain airports require more (3 hours is common in some).

6. After checking you go to the Baggage Drop area for Checked Luggage only. If you do not have any checked luggage, skip this part completely.

7. Head to the security entry point. This often varies depending on your gate (which implies your next destination). So even you have an internal trip, a first domestic leg will usually make you go through domestic security.

8. Most but not all countries also perform exit immigration to check who is leaving the country, sometimes they collect a departure tax during this step.

9. Go through security and head to you departure gate. Gates change more frequently than any other thing and so be sore to check on airport monitors and listen to loudspeaker announcements for gates changes for your flight. Keep an eye on your belongings there.

10. Optional but highly recommended: Use the airport bathroom. Plane bathrooms are really uncomfortable and can have long lineups because they are not usable during certain times (take-off, landing, turbulence).

11. Wait to the gate area and keep listen to announcement. They may announce a gate change, delay or simply call people to perform secondary verification. Eventually they will announce boarding by class and/or group number (which is written on your boarding pass). Line up when they call your turn and be sure to stand in the correct line. Larger planes can have multiple boarding lanes for different classes and groups.

12. Board the plane, taking note of where you place your luggage if you use the overhead bins or if you were asked to hand-over a larger bag, stroller, baby-chair (for gate-checking) during the process.

13. Make yourself as confortable as the space allows it and enjoy your flight!

What are the steps for flying?

1. Buy your ticket. This is almost always done online, but can be done by phone or through a travel agent. You may be asked to give passport details at this stage. You will also be told how early before your departure time you have to be at the airport - usually from 1 hour for a short domestic flight to 3 hours for a long international flight.
2. Online check-in. Usually done up to 24hrs before the flight. This lets the airline know you really intend to fly, and allows you to check if your flight's time has changed. For international flights you will have to give passport details here. Often you get to choose your seat at this time, so do it early. Often you can print your boarding card.
3. Check-in at the airport. This can sometimes be skipped if you have done online check-in and have only cabin baggage (items small enough to keep with you in the plane). If you don't have a boarding card or need to check bags you need to do this. You need to have your ID checked. It may be done by machine or by a person. Bags other than cabin bags will be taken from you here. You will probably need to wait in line, possibly a long one. If you didn't check in online be sure to arrive early.
4. Go through a security check. Your bags will be scanned, and you will be searched or scanned too. Up to this point someone who isn't flying can stay with you, but they will not be allowed through security. Some people wait a bit before going through security, but it's best to go through right away. There are often lines to get through security. There are places to eat, drink and shop after security. For countries that check passports on exit this will be done around here.
5. Boarding the plane. Your boarding card usually tells you which gate your plane departs from, and there are also screens telling you the gate and time when boarding of the plane will start. Keep checking them as they can change. Get to the gate early - boarding can start up to an hour before departure.
