In airline pricing and ticketing, <strong>TC1</strong> stands for <strong>Traffic Conference Area 1</strong>.
It represents the <strong>Western Hemisphere</strong> and is one of the three global IATA Traffic Conference Areas.
</p>
<p class="note">
TC1 includes <strong>North America, Central America, the Caribbean, and South America</strong>.
If a fare rule says “within TC1” or “between TC1 and TC2,” this geographic definition is what it refers to.
