Google Flights Search compares airline and OTA booking options in an organic metasearch experience and hands travelers to downstream partner booking surfaces. The public partner overview distinguishes airline and OTA onboarding, while detailed partner specifications may be shared with selected partners under NDA.

## Ownership boundary

```text
Partner supply / fare state
   -> Google Flights Search
   -> traveler selects booking option
   -> partner deeplink
   -> airline / OTA booking surface
```

Google Flights is not the downstream booking engine; transaction ownership remains with the partner.

## Canonical partner model

Preserve itinerary, carrier, booking partner, displayed total, currency, fare context, deeplink, observedAt and source reference.

## Price and handoff accuracy

A core metasearch metric is alignment between the displayed search price and the downstream landing/booking total. Deeplinks should preserve as much selected itinerary/fare context as the partner contract allows.

## Integration boundary

Google's public page explicitly says partner integration specifications can be confidential/proprietary and shared under NDA. Therefore:
- do not invent non-public endpoints or fields,
- do not present account-specific requirements as universal public contracts,
- use public documentation to define architecture boundaries only.

## Observability

Track landing success, price mismatch, deeplink context loss, stale offer age, booking-option coverage and click-through.

## Checklist

- airline/OTA ownership explicit
- deeplink context preserved
- displayed price vs landing total measured
- source/reference traceable
- private partner specs separated from public docs
