A week after the upgrade was rolled out, BA is still manually processing passenger information because of systems failures. The company admits it is still days away from a solution.
A spokeswoman for BA said, "We are working with our [IT services partner] Amadeus to resolve this problem. We are now seeing a significant lessening of problems and hope to be up and running after a few more days."
BA admitted that it experienced a number of system failures following an upgrade on 13 March. These include links from the BABS (British Airways Booking System) and the DCS (Departure Control System) to the company's mainframes.
BA was unable to retrieve some passenger booking information, which resulted in flight delays of up to 45 minutes, disruption to check-in desks and the cancellation of more than 100 flights by the beginning of this week.
BA would not comment on how many passengers had been affected by the systems failure or how much it had cost the company overall.
