American Airlines said Friday it has temporarily suspended its operations into Caracas and Maracaibo, after its pilots union urged its workers to deny trips to Venezuela in the wake of a travel advisory issued by the US State Department. The department cited civil unrest, poor health and arbitrary arrest and detention of US citizens in Venezuela for issuing the advisory March 12. A number of airlines have stopped their flights to the South American country because of security concerns and disputes over money they say the Venezuelan govt owes them. "Our corporate security team has a collaborative partnership with all of our union leaders and we will continue to do so to evaluate the situation in Venezuela," the airline said, adding that American will not operate to countries it does not consider safe. <br/>
