Example 1:
You are looking for a Round the World fare in the September Worldwide Rules book. All Round the World fares are included within rules in the
R rule series and you are looking for the relevant R rule for the journey required. It is not published in the September book. That means that it
has not changed since the quarterly edition. Go to the July Worldwide Rules book to find the relevant R rule and fares.
Example 2:
You are looking for fares data (not IT fares) in the August Worldwide Fares book. This section is published in full. Use the information in the
August Worldwide Fares book.
