# Flight Priority in Reach Extension

For Reach Extension contracts, Triton first considers owner priority then reseller priority to select reseller flights.

## Key Takeaways

- Owner priority determines if reseller demand is considered.
- Reseller priority determines which reseller flight to serve, but only within the same inventory scope.
- Different inventory sources are evaluated independently.

## Owner Priority Is Evaluated First

- The priority set by the owner on the delegate flight controls when reseller demand is eligible.
- That delegated flight competes with the owner’s other flights at the same priority level.
- Only owner campaigns are evaluated at this stage, including the delegated flight.
- Reseller campaigns are not considered yet.
- If the delegated flight does not win at the owner level, the reseller is never evaluated.

## If the Delegated Flight Wins, Reseller Priority Applies

If Triton selects the delegated flight, the request is passed to the reseller.

Inside the reseller space:

- Only reseller flights targeting that specific allocated inventory are evaluated.
- Reseller priorities are compared only against other reseller flights targeting the same inventory source.
- Flights targeting different publishers or contracts do not compete with each other.

### Example

- Owner delegated flight: Priority 8
- Reseller flight targeting that contract: Priority 4

Flow:

1. Owner flights are evaluated first.
2. If the delegated flight (Priority 8) wins, the request moves to the reseller.
3. Among reseller flights targeting that same inventory, the Priority 4 flight wins.
