You already know your flight is scheduled on a specific date and time. You also know which airport you'll have to go.

You're flying tomorrow and you can do your web check in. You can also do it at your airline desks up to three hours before your departing time.

But first thing first: What is this procedure called "check in"?

Well, let's see what the Cambridge Dictionary has to say about it...

It depends on the way you're checking in.

if you're checking online, then you'll have to provide:

• Date of flight ( Airlines allow you to proceed with your web-check in 36 hs before your flight time);
• Name and surname;
• Booking code (it usually consists of six letters);
• Origin (Which airport are you flying from?);
• Flight number.

Here you have a print-screen of Aerolineas Argentinas web check in form. Let me tell you that the first slot to complete is misnamed: it should say "Date of flight". If you click, the displaying menu will show you two options: Today - Tomorrow/36 hs.

Remember all the documents we talked about the last class? Well, if you're checking for a domestic flight, you will have to show your ID. International flights require.....That's correct! You'll have to show your passport to check in an international flight.

Once you've completed your check in, you'll know your seat number, boarding gate and boarding time. All that information is printed on your boarding pass.

Now you can go for a coffee at one of the several coffee shops available in the airport and wait for your call to board.

Call? Yes, you'll be called to board so you have to pay attention to the announcements.

As a general rule, when the boarding process to a flight is about to start, all its passengers are called the same way:

• Airline and flight number;
• Destination;
• Boarding gate; and
• Boarding time.

Flight numbers consist of a combination of letters and numbers, so knowing your ABC will be of great help to listen to your boarding announcement.
