The flight returned to Dublin airport after just before 9pm last night in an emergency landing.
The plane had left Dublin at 4.23pm yesterday afternoon and two hours and fifteen minutes into the flight a decision was made to return to Dublin as a “number of cabin crew members reported that they were feeling unwell,” said a spokesman for the airline.
The aircraft crew were met by medical officers and Aer Lingus says it is investigating the incident.
There were 280 passengers on board. They were accommodated last night and will fly to Boston tomorrow.
