Aer Lingus A320 EI-DEA operated EI392 Dublin – Hamburg this afternoon. However, due to a security staff strike at Hamburg no outbound passengers were able to be processed and therefore the return EI393 was cancelled. Instead of positioning back to Dublin, following the earlier A320 technical issue at Paris, the aircraft instead positioned Hamburg – Paris CDG as EI993P in order to operate the delayed EI523 Paris CDG – Dublin.
