Terrible experience, flight was delayed both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.

Terrible experience, flight was delayed both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.

The boarding was relatively quick, the crew welcoming and flight uneventful. The omission of meals on all airlines is unacceptable especially when the flight is during a mealtime such as this one, (lunchtime), is unacceptable.

Everything was simple and easy. The lady at the gate was super friendly, I wish I had her name to share. She's a little older, dark-haired. You can tell she likes her job and would be a great influence on any young people training with her.

During the pre-departure safety briefing, the flight attendants rushed through the mandatory safety announcements in both official languages, making it difficult for passengers to clearly understand the instructions. Given the importance of these messages for passenger safety, this lack of clarity was concerning. Perhaps use a recoded message to alleviate this concern. Additionally, the flight attendants appeared to lack the professional attentiveness typically expected during a flight. Rather than focusing on timely and courteous service, they seemed more engaged in personal conversations than in addressing the needs of passengers. I hope this feedback is taken constructively and helps in maintaining the high standards of professionalism and care that travelers expect from a national carrier: AC.

No Charging ports for personal electronics, which were required to use wifi entertainment.

an absolute disaster and nightmare on air condition. IT WAS FREEZING!! everyone around us had hats, hoodies, gloves outdoor jackets on. that segment of the aircraft had a fault I assume...no amount of suggestion to turn down the air con helped. otherwise all good.

Seats were comfortable, flights boarded easily, arrived early in Toronto and on time in Nassau

As mentioned previously the professionalism and speed of the Air crew was amazing… Sarah in particular was a joy to observe and interact with, she made my flight!

Rushed, the boarding was a great deal like a Chinese fire drill.

Poor planning meant the plane was delayed an hour, then a thunder storm started and the ground staff couldn't work. Eventual arrival in Santiago was 3 hours late resulting in missed connections and the need to buy new tickets.

Booked through Kayak, couldnt take flight, Kayak punted to Orbiz, Orbiz punted to Aer Lingus, Aer Lingus said sorry about your luck, try Kayak/Orbiz. Terrible customer service collecting air fares and not even offering a voucher when customers cant take flight

Very polite and helpful staff. Jet blue…ok, but not as helpful!..

Seat was very uncomfortable. The worst in all of my travels. It sagged in the middle, worse than anything any airline can offer. Not flying aer lingus again.

This flight was delayed and caused me to miss my connecting flight from New York to Boston. I had to rent a car and drive myself home to avoid waiting another 5 hours in the airport.

My Aer Lingus flight (booking ref # 2SU4LF) was the worst travel experience I have ever dealt with. My flight from Paris to Dublin was delayed by over 2 hours which caused me to miss my connecting flight back to the US. I was not able to be rebooked on a new flight for another 3 days. When I finally made it on my rescheduled flight, it was delayed AGAIN, causing me to miss my connecting flight from New York to Boston. At this point I decided to just rent a car since the next flight I would have been able to get in wasn’t for another 5 hours. It was a complete nightmare experience and I will never fly Aer Lingus again. I have requested a refund from the booking company I placed my order with.

They couldn't do through check-in for us. They took 2 hours to issue just one leg of the boarding pass. They had no idea to handle the case of passengers who travels to USA via Dublin airport. we had tough time time Dublin airport as boarding pass for the US flight was not pre-issued. Hope Aer Lingus will learn to handle such cases which they couldn't learn in in the past 50 years of the service.

There was a very drunk and disruptive passenger who was on the plane, right behind me. He was already drunk before boarding but was still let on the plane. He kept kicking and hitting the back of my chair the entire flight. It was an early morning flight and had zero rest on that leg

Really lovely trip and flight. The flight staff were so accommodating and warm throughout!

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Very sad, couldn't stop crying. Was an hour delay in Ireland and when we got to Canada the flight was boarded and couldn't get on. Was the last flight of the day. Now in a hotel waiting on a stand by.I have to got o work, so I'll go first available while my son stays in the hotel til one's available
