The NSW government intends lobbying Canberra for more flights through Sydney Airport, potentially in the early morning and late at night.

The airport is restricted to 80 an hour but NSW Deputy Premier Andrew Stoner said he would be "vigorously lobbying" his federal counterparts for change.

The state government wants 85 flights an hour.

This would require rewriting the federal Sydney Airport Demand Management Act, which would raise the ire of people near the flight paths.
