A US Airways Airbus A330-200, registration N289AY performing flight US-715 from Venice (Italy) to Philadelphia,PA (USA) with 238 passengers and 12 crew, was enroute at FL400 about 180nm west of Shannon (Ireland) about to enter the Oceanic Crossing when the crew decided to turn around and divert due to a number of flight attendants becoming sick. The crew requested to divert to London Heathrow but was told that they would need to declare a medical PAN to get into Heathrow, otherwise they would need to divert to another airport. The crew decided to divert to Dublin (Ireland) and landed safely on Dublin's runway 10 about 50 minutes later.
The airline reported 3 flight attendants reported medical issues and were evaluated by paramedics after landing.
Flight US-715 had diverted to Dublin 9 days ago already for a very similiar problem.
