Booked an international Aer Lingus flight on February 1, and about a week later the airline cancelled the flight.
Initially requested a voucher, but after two weeks with no response switched the request to a cash refund instead. Another week later an email came saying the case was being worked on, but nothing actually happened.
After waiting longer, a credit card chargeback was filed just to try to get the roughly $1,000 back.
Shortly after that, another email arrived saying they were still handling the case and asking to stop submitting additional customer service requests.
Since airlines are supposed to provide a full refund when they cancel a flight, it’s frustrating that the process is dragging on this long.
