A US Airways Airbus A330-300, registration N278AY performing flight US-703 from Frankfurt/Main (Germany) to Philadelphia,PA (USA), was enroute at FL380 over the Atlantic about 350nm southeast of St. John's,NL (Canada) when the crew received a low oxygen pressure warning with the pressure further decreasing. The crew declared emergency, performed oceanic contingency procedures to descend to 10,000 feet without clearance and requested to divert to the nearest airport at St. John's, where the aircraft landed safely about one hour later.

The Canadian TSB reported maintenance found a small leak in the captain's oxygen mask. The mask was swapped with the observer's mask, the oxygen bottle serviced and a leak check performed, the aircraft was subsequently returned to service.

The aircraft continued the journey and reached Philadelphia with a delay of 4:15 hours.
