You can edit a flight simply by going to the flight and making the changes you prefer. Note that there are some restrictions. You can also re-activate a completed (status is Done) flight. However, remember that flight Status and flight Delivery Status are separate and use different rules.

Edit an Active Flight
To edit an active flight, go to the flight and make the changes you want, then select Save Flight.
You can only change a flight's Start date when its Delivery Status is Pending.
You cannot change a flight’s Net rate, Gross rate, or Priority type when its Delivery Status is Ready.
Extend a Completed Flight
After a flight has completed (when its status is Done), you can extend it by reactivating it and extending the end date.
In Flight overview, change the status from Done to Active.
In Delivery details, change the End date to a date later than today.
In Delivery details, update the Goal to add additional impressions if the flight had delivered at or near 100% when it completed. This step isn't necessary if the flight ended without achieving its goal, in which case you can extend the flight to try to achieve the original goal.
Select Save flight.
Reactivate a Paused Flight
To reactivate a paused flight, change the status in the flight overview from Paused to Active.
