Check-in system failure affects 485 airlines worldwide.

From News.com.au:

ALL Qantas check-ins have been thrown into chaos, after the computer check-in system failed across the country and the world.

The Amadeus program used by Qantas to check in passengers went into meltdown at about 5pm (AEDT) yesterday across the network, the Herald Sun reports.

The computer glitch was rectified just after 8pm, but the airline reported delays of between 45 minutes.

Qantas said services across the country are returning to normal.

During the system shutdown staff were forced to check people in manually, which was the major cause for delays.

All Qantas flights across the country were affected, along with another 485 airlines across the world.

Major airlines such as British Airways, Air France, South African Airways, Thai Airways, Lufthansa and United Airlines were all affected in the global check-in chaos.
