How do I read an Amadeus availability display (AN)?

AN20OCTLJUFRA shows flights from Ljubljana to Frankfurt on 20 October. Each line lists the booking classes and their seats: 9 means nine or more, 0 closed. A class with seats is not yet a price — pricing comes after selling.

When

You look for flights on a date and city pair and need to understand what the screen tells you before selling a seat.

Connections show as two lines under one number; the second flight continues from the first one's arrival airport.

Check it worked

The header shows the city pair and date; line 1 is the first flight from the time you asked.

Traps

  • A class with seats is not a fare. Availability shows seats per booking class; the price comes from pricing (FXX/FXP) after selling.
  • Different offices can see different classes (airlines suppress classes per market).
  • Seat counts on Standard Access airlines are approximate; they can be refused at ER.
