In airline pricing, ticketing, baggage rules, and routing logic, you’ll often hear about
<strong>IATA Traffic Conference Areas</strong> (also called <strong>Tariff Conference Areas</strong>).
IATA divides international travel into <strong>three main geographic areas</strong>: <strong>TC1</strong>, <strong>TC2</strong>, and <strong>TC3</strong>.
</p>
<p class="note">
<strong>Key idea:</strong> TC1 is commonly described as the <strong>Western Hemisphere</strong>, while TC2 and TC3 are the <strong>Eastern Hemisphere</strong>.
A commonly used dividing reference between TC2 and TC3 is the <strong>Ural Mountains (Russia)</strong> and <strong>Tehran</strong>.
(You’ll see this phrasing in multiple airline/GDS training references.)

<h2>Why travel professionals use TC Areas</h2>
<ul>
<li><strong>Fare construction & routing:</strong> many fare rules depend on whether travel is within one TC or crosses into another.</li>
<li><strong>Baggage logic:</strong> systems may apply rules based on which TC Areas your journey touches (important for interline and codeshare cases).</li>
<li><strong>Training shortcuts:</strong> it’s easier to say “TC1–TC2” than list dozens of countries every time.</li>
</ul>

<h2>Quick terminology (beginner-friendly)</h2>
<ul>
<li><strong>Traffic / Tariff Conference:</strong> the “TC” label is used in pricing and rule frameworks.</li>
<li><strong>Sub-area:</strong> a smaller region inside a TC (example: “Europe” inside TC2).</li>
<li><strong>Western vs Eastern Hemisphere:</strong> TC1 is typically described as Western; TC2+TC3 as Eastern.</li>
</ul>

Notes you’ll commonly see in training materials:
TC1 is Western Hemisphere; TC2 and TC3 together are Eastern Hemisphere; and the Ural Mountains/Tehran reference is used as a divider between TC2 and TC3 in some systems and guides.

<h2>Sub-areas inside each TC (the practical “complete” breakdown)</h2>
<p>
In day-to-day airline work, you often need sub-areas because many rules are written at sub-area level
(for example, “within Europe” or “Japan/Korea”).

<li><span class="pill">Mexico</span> (sometimes handled separately in rules)</li>

Used for rules that differentiate (for example) “North America–Caribbean” vs “South America–Central America”.
Many airline references explicitly show TC1 sub-areas like North America, Central America, Mexico, Caribbean, South America.

<td><strong>TC2</strong></td>
<td>
<ul>
<li>Europe</li>
<li>Africa</li>
<li>Middle East</li>
</ul>
</td>

Common for fares and baggage rules written as “within Europe” or “Europe–Middle East”, etc.

<td><strong>TC3</strong></td>
<td>
<ul>
<li>Japan / Korea</li>
<li>South East Asia</li>
<li>South Asian Subcontinent</li>
<li>South West Pacific</li>
<li><span class="pill">Other Asia / Asia Pacific</span> (varies by carrier rule text)</li>
</ul>
</td>

Often used to separate pricing and rules for (example) Japan/Korea vs South East Asia vs South West Pacific.

Practical tip: Airlines and GDS tools sometimes show “TC Areas” and “Sub-areas” together.
When you read a fare rule, always check whether it says <span class="kbd">TC</span> (big area) or a specific <span class="kbd">sub-area</span>.

<h2>Mini examples (how this shows up in real work)</h2>
<ul>
<li><strong>Example 1:</strong> A fare might say “valid for travel between TC1 and TC2” → you’re crossing the Americas to Europe/Africa/Middle East.</li>
<li><strong>Example 2:</strong> A baggage rule might depend on whether your journey crosses from TC2 to TC3 → Europe/Middle East/Africa into Asia-Pacific.</li>
<li><strong>Example 3:</strong> A training question might ask “Is Brazil in TC1 or TC2?” → Brazil is in TC1 (Americas).</li>
</ul>

<h2>Study checklist (quick recap)</h2>
<ul>
<li><strong>TC1</strong> = Western Hemisphere (Americas + Caribbean)</li>
<li><strong>TC2</strong> = Europe + Middle East + Africa</li>
<li><strong>TC3</strong> = Asia + Asia Pacific</li>
<li>Sub-areas are used heavily in fare rules and industry training</li>
</ul>

<h2>Knowledge check (for students)</h2>
<ol style="color: var(--muted);">
<li>A journey from Canada to France crosses which two TC Areas?</li>
<li>Which TC Area includes “Asia and Asia Pacific”?</li>
<li>Name two sub-areas that belong to TC3.</li>
<li>Why do fare rules use TC Areas instead of listing every country?</li>
