BA confirmed yesterday that links between the company's mainframe computers and its BABS (British Airways Booking System) and DCS (Departure Control System) had been restored, but warned minor delays could continue for several days.
A spokesperson for BA said: "At 11.00 on Tuesday night the computerised check-in system was suspended for a couple of hours. During that time problems with the links were resolved. Everything is OK at the moment, and there were no flight delays this morning as a result of [complications with] the system upgrade, which is good news after a week."
BA hit problems following a poorly implemented system upgrade on 13 March by its Spanish-based IT services partner, Amadeus Global Travel Distribution SA.
