This happened on 10 September. If it had happened on 11 September, we would have a load of extra conspiracy theorists asking how it could happen to an airline the size of Aer Lingus that has the backup of the International Airlines Group with its technology, including airlines such as British Airways, Iberia, Vueling, and other large airlines, each with hundreds of aircraft. Most people, not just the 30,000 passengers who were affected, looked at it and thought it was absolute chaos. In the old days, there were paper tickets and boarding passes. Those manual systems are long gone and we now have a system that is 100% technology based, yet there is no third backup. Will there be a third backup in the future?
