Campaign Flights allow a Campaign to be divided into separate date ranges with individual budgets. Flights provide more granular control over when Campaign budget is available and how that budget is distributed across Lines throughout the Campaign.

Flights are optional and are enabled at the Campaign level. When Flights are not enabled, the Campaign and its Lines operate against their standard Campaign and Line date and budget settings. When Flights are enabled, the Campaign can contain multiple Flight periods within the overall Campaign date range. Pasted text

A single Line can participate across multiple Flights. Depending on whether Manage Budgets is enabled, each Flight can use different Line Budget Allocation Weights or manually configured Line Flight Budgets.

Flights are useful for Campaigns that need to:

• Divide budget by week, month, promotion, or other scheduled period.
• Allocate different amounts of budget to different Lines throughout the Campaign.
• Pause delivery between scheduled periods.
• Roll unused budget into future Flights.
• Monitor pacing against a specific Flight in addition to the overall Campaign.

Flight Hierarchy

Flights are managed within the Campaign but do not change the relationship between the Campaign and its Lines.

    └── Campaigns
        ├── Flights (optional)
        └── Lines

Each Campaign belongs to a single Advertiser and contains one or more Lines, which control bidding and delivery. Campaigns can optionally use Flights to divide the Campaign into separate date ranges with individual budgets and Line allocation settings.

When Flights are enabled, the same Line can participate across multiple Flights with different budget allocations without changing the Campaign-to-Line hierarchy.
