dateRange property
The flight start and end dates of the line item.
They are resolved relative to the parent advertiser's time zone. *
Required when flight_date_type is LINE_ITEM_FLIGHT_DATE_TYPE_CUSTOM.
Output only otherwise. * When creating a new flight, both start_date and
end_date must be in the future. * An existing flight with a start_date
in the past has a mutable end_date but an immutable start_date. *
end_date must be the start_date or later, both before the year 2037.
