| Enumeration | Description | 
|---|---|
| EVENLY | Line items are served as evenly as possible across the number of days specified in a line item's LineItem.duration. | 
| FRONTLOADED | Line items are served more aggressively in the beginning of the flight date. | 
| AS_FAST_AS_POSSIBLE | The booked impressions for a line item may be delivered well before the LineItem.endDateTime. Other lower-priority or lower-value line items will be stopped from delivering until this line item meets the number of impressions or clicks it is booked for. |
