# ATPCO

ATPCO is a central source of filed airline fare and optional-services data used across shopping, pricing, and retailing.

ATPCO is an airline industry source for filed fare, rule, and optional-services
data. Travel sellers use ATPCO content to understand what an airline has filed
for a fare or ancillary choice. It matters commercially because structured
filing turns airline pricing rules into content that can be shopped and sold.

## What ATPCO does

ATPCO sits behind much of the structured fare and optional-services content used
in air shopping. The practical role is standardisation. Airlines need a way to
publish complex rules and prices so sellers can present them in a consistent
commercial form.

For a seller, this matters because fare and ancillary content is not just text.
It carries rules about eligibility, price, geography, timing, and conditions.
Without structure, it is hard to show a traveller what applies to their trip.

## How it differs from NDC

ATPCO and NDC are often discussed together because both affect airline retailing,
but they are not the same thing. ATPCO is associated with filed content. NDC is a
distribution standard for richer airline offers.

The distinction helps teams avoid vague architecture conversations. One term is
about the content that has been filed. The other is about how richer offers can
move through distribution.

## Why it matters for merchandising

Merchandising depends on trustworthy content. A paid option should not be shown
unless the seller can explain what it is, when it applies, and what the
traveller receives.

ATPCO matters because it gives many airline options a structured base. The
commercial work still belongs to the seller: deciding when the option appears,
how it is explained, and whether it makes sense in the traveller's journey.
