A Hawaiian Airline flight to Sydney, Australia needed to return to Oahu Sunday afternoon after take-off.

An airline spokeswoman says Flight 451 departed Honolulu with 201 passengers on board. About an hour and a half into the flight, the captain decided to return when a cockpit light indicated low pressure in one of the plane’s three hydraulic systems.

According to the spokeswoman, the captain did not declare an emergency and the plane landed safely.

The 201 passengers were given meal vouchers and were being booked on the first available flight.
