Canceled Flights, Ash Cloud | featured news

An ash cloud drifting around the world for a second time after spewing from a Chilean volcano more than two weeks ago is once again grounding commercial jets and stranding thousands of passengers in Australia.

Meanwhile, some German airports were reopened Wednesday after cancellations due to the cloud of volcanic ash. Bremen has reopened and Hamburg is allowing takeoffs and landings, according to Deutsche Flugsicherung, the German aviation safety agency. Airports in Berlin will resume flights at 2 p.m. local time ( 8 a.m. ET).

The spread of dense ash from the erupting Iceland volcano could force the cancellation of up to 500 commercial flights in Northern Ireland, Scotland and parts of Scandinavia, the European air traffic agency said Tuesday.

New eruptions send volcanic ash cloud toward Britain and threaten plans to resume flights.

A huge ash cloud from an Icelandic volcano spreading out across Europe is causing air travel chaos on a scale unseen since the September 11 attacks and costing airlines hundreds of millions of dollars.
