Brazil Airline System in Uproar

BBC News:

Brazil's president has demanded that the country's aviation authorities take action to end months of delays and temporary closures at major airports.

On Thursday, angry passengers staged a protest on the Tarmac in Brasilia.

In recent days up to 44% of flights have been delayed or cancelled, according to the authorities.

The problems started in October when air traffic staff began a work-to-rule protest following the deaths of 154 people in Brazil's worst plane crash.

Air traffic controllers say they are overworked, underpaid and understaffed, putting safety at risk.
