Two Aer Lingus flights have been delayed due to a dispute between management and cabin crew that led to weekend delays and cancellations.
The dispute is over proposed new work practices with workers concerned over shorter turn-around times, including a possible curtailment of meal breaks.
A spokesperson for Aer Lingus told ireland.comthere have been no cancellations and operations are running "normally".
However, a flight to London City was delayed for one hour this morning and this afternoon's 4.15 flight to Glasgow will also be delayed by one hour.
The spokesperson said all other flights are running according to schedule.
Four flights were cancelled over the weekend as crew staged a work-to-rule protest, refusing to travel on flights that were short of agreed staff numbers.
A flight from Shannon to Boston was cancelled on Saturday and some 200 passengers had to stay overnight in Clare and Limerick after a member of staff became sick before take-off.
Four flights were cancelled over the weekend, but Aer Lingus has advised passengers to check in as normal.
