In the last few minutes, Dublin airport has joined Cork and Shannon in reopening to airline traffic. Shannon and Cork reopened earlier this morning. The IAA has announced the reopening:

The Irish Aviation Authority (IAA) has announced that as a result of the ash cloud continuing to move away from the South East of Ireland, it is lifting restrictions within Irish airspace except for a block off the south coast of Ireland. This effectively means that Dublin Shannon and Cork Airports will be open for flights.

Flight restrictions into Northern Europe still prevail. Parts of British airspace will be closed until early tomorrow morning, barring a clearing of the ash cloud from the skies.

Update – 11:07am: Channel 4 is reporting that long-haul flights to Gatwick are being diverted to Glasgow, as Heathrow and Stansted remain closed until 1am tomorrow morning.

Update – 12:17pm: Quickfire status on European airspace that remains affected by the ash cloud.

Airspace over Northern France remains closed until 8pm. Dutch airspace closed until 6am tomorrow morning. Danish airspace will be closed until midnight. Belgian airspace will remain closed today.

Flights to and from Finnish airports have been affected. Finland is expecting a new cloud of volcanic ash to arrive tomorrow morning, so restrictions look set to continue into the weekend.

Krakow airport has closed as well. It was scheduled to host arrivals for the state funeral of former President Lech Kaczynski. Airspace in Poland, Austria, Latvia, Lithuania and the Czech Republic has been closed.
