Has BA taken the opportunity of the last year to update its software
In August 2019, BA was forced to cancel many flights at three London airports due to a software glitch. In 2017 there was a severe software failure. According to the FT, senior software engineers had been let go, and systems had been outsourced to Tata Consultancy Services in 2016, though it was said that they were not responsible for the crashes. BA has dozens of old legacy systems. And at the same time there is conflicting pressure to provide new capabilities and features. It was said in the FT that BA's old legacy systems are very hard to migrate off. Low cost carriers like easyJet, it was said, have simpler systems that can offer better customer services and maximise revenue.
I'm SLF and not IT, but it occurs to me that the last year will have been an ideal time for BA to have been updating its old legacy IT systems, and install and test updates, to reduce the possibility of future software crashes like those in the recent past. Does anyone know if BA has been doing this?
