Following the earlier technical issue at Cork, Aer Lingus A320 EI-CVA positioned Dublin – Cork as EI991 early this morning in order to operate the delayed EI874/EI875 Cork – Tenerife South rotation. Then, due to a second A320 technical issue at Cork, the aircraft operated the EI846/EI847 Cork – Brussels rotation in the afternoon before positioning Cork – Dublin as EI993.
