Last year (I am told) there was a similar IT mess up!
A company growing as fast as EZY will always have IT problems. Additionally everybody moved from EASYLAND to HANGAR 89.
This should be no excuse, just a rational explanation.
Of course it is BS to write down all data again!
Maybe it is motivating for you, if you make into EZY, you are flying for a (meanwhile) airline, worth flying for. Is it money or a stable roster.
