Things are looking worse for the airline industry.
Worldwide, they're expected to lose $9 billion in 2009.
The new estimate comes from the International Air Transport Association, representing 230 airlines around the globe.
In March, the IATA predicted a loss of $4.7 billion.
They say the ground has shifted with the worldwide financial crisis.
The head of the group says airlines need to make drastic changes to the way they do business.
