The pilot came out and chatted with the passengers. He explained why there was a slight delay. The crew was excellent. Very helpful. I had to buy meals for my whole family and they were in different seats, so the crew had to deal with that. They were very pleasant and accommodating and did a great job!

I had to buy meals for my whole family and they were in different seats, so the crew had to deal with that. They were very pleasant and accommodating and did a great job!

We were unable to land in Liberia. It was not the airline’s fault, but we had to be diverted to SJO.

We had things stolen from our luggage, we also were refused an upgrade on a flight that was not full.

When we left, it wasn't Great . People were drinking heavily, very disrespectful Extremely loud, the entire trip. I think the crew members, should have get their attention. Coming back was great.

I sat in the club. The seeds were fantastic. The meal was great and Entertainment was good. The crew was fantastic. I recommend it to everybody.

The food was small portions and not fresh. I was seated at the back of the plane so by the time the cart approached me most of the food options were sold out. The cabin crew was fantastic however.

Great flight and crew. Food isn't free and neither are headphones...

We were in economy class but paid for option Plus which offer you an extra snack after take off, free earplugs & blanket. The crew were very attentive. The comfort however wasn’t great, hard to be comfortable in such restraint place. Wasn’t able to sleep through out the 7hrs flight and was exhausted upon arrival.

The flights were on time and the crew was friendly and helpful. The food was ok. The seats were quite cramped and if the seat in front was tipped back there was very very little room. The entertainment was only on your own device and there was no usb charging

Boarding and staff were excellent. The food was ok. Very cramped seating. No existent entertainment other than on iPhone over wifi with poor choices of movie or shows. Bring your own entertainment. Nowhere to charge your phone

Too squished in seats. I'm 110 lbs and 5'6....can't imagine being any bigger and flying

WestJet claims that tickets purchased through a 3rd party (such as you kayak) they cannot make sure they mention the luggage situation. We purchased tickets that wouldn’t allowed any carry on. WHAT!? So ridiculous. We bought them and there was not one single place mentioning that. Then on our departure the WstJet attendant was a super nasty rude person. Very unprofessional, unpleasant. She should be reprimanded and given some sort of training but I believe that won’t change her nasty disposition. On our return was great, the front desk gentleman was really professional, friendly and helpful. He offered us to pay $18 usd each for our carry on backpacks as they were small (instead of $90 each at the departure, she could have mentioned but decided not to do so. Didn’t print my boarding pass with my full name as in the passport and made the flight delay because the crew needed to correct it).

Original flight canceled and communicated poorly. A series of gate changes , delays and plane changes followed. Even after the entire flight boarded there was another plane changes followed. Food vouchers provided to my travel companion but not to me despite being on the same reservation. No in flight entertainment. The entire experience was terrible although the flight crew were great.

Flight was on time. Online check in capabilities made things quick and easy. Zone boarding was enforced, which I appreciate. Everyone was not lining up ahead of their zone being called. Crew was professional and friendly.

Dogs. Dogs. Dogs ! Who the hell thought letting dogs on board was a good idea ? Yapping dogs on both flights ! They ruin the experience for everyone else around because you try to accommodate everyone. Please send me a refund.

We booked Premiere (their version of first class) and Premium Economy seats. We boarded an old swoop flight with all coach seating. No benefit to paying higher fare and no apology or reimbursement.

The big lady was sitting right next to me and the button to recline my seat was blocked by her huge arm. No power outlet for chargers. No inflight Wi-Fi movies

Trip was uneventful which is good. Boarding took a long time due to many disabled/elderly requiring assistance which again is fine. Landing and take off were excellent. Food and entertainment were as expected, bring your own if you have preferences otherwise you get what you get.

Check in agent was good, stewardess was unfriendly and certainly did not have the care of the passengers in mind Spent the whole time on her phone

Wasn’t able to purchase wifi for entertainment so the flight was long

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.

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

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

Both flights late. Almost missed connecting flight and flight staff not willing to help expedite us off the plane.

during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.

I didn’t realize Aer Lingus was a “nickel and dime” kind of airline where you had to separately buy all the amenities you wanted. The push to purchase duty-free beauty products was off-putting. And our row had the least amount of leg room I’ve ever dealt with on a flight.

It would have been better to have USB charging ports available on the longer haul Flight that one of 2 hours

Was very good Staff was great. No tv monitors tho. So long flights make it longer

The worst. No free beverages. No entertainment on an overseas flight. Not enough space. Never again.

Play is affordable! Only way we fly from the states to Europe. Left late but arrived on time

have screens on backs of chairs...offer free snacks and water

Boarding and crew was great. Flight was cold, need layers. Deplaning was hard. We had to take stairs off the plane and I was separated from my travel companion because we were not seated together and they would not let him wait for me to get off so we were forced onto different shuttles.

Check in and boarding was easy, crew was cheerful. Not much to read or do on the plane and our neighboring passengers were talking loudly so we could not sleep. But overall good. Great coffee.

Flyplay is the only way I travel to Europe. Had a 15 hr layover in Iceland. Normally this would suck, but I regret a car and saw the black sand beaches, several waterfalls and sky lagoon. And finished with lamb at cafe Loki.

did not get the seats we had specially paid for

This is a no frills airline. You cant expect much for the price. Low cost flight, clean, nice staff. That's all I need for the price. If you want more, book with another airline and pay more. For Europe trips, PLAY is the ONLY airline I use

I was not even asked if I want some water. Joke. Steward gave me a biscuit cover in chocolate and did not even look at me.

Ok Did not like that the second leg of flight was moved earlier making it a rush to make

We had a lot problems in beginning but Air Canada took very good care of us

My flight was delayed, causing a shortened connection to my second flight, which led to a stressful experience. Additionally, I had to pay the luggage fee twice, for which I have receipts. Since Air Canada and United Airlines collaborate, their partnership should aim to provide better service, rather than leaving passengers to bear the consequences of an unprofessional experience.

One leg of the flight arrived late which necessitated a rebooking on the next leg. Although there were no major weather events in play, best choice offered was a 7 hour wait in the Vancouver airport for a 4 hour totally packed red eye flight to Ottawa. No opportunities to return earlier via other major hubs like Toronto or Montreal. Felt very much like national routes were no longer well supported. Adding insult to injury, entertainment system for my seat was out of order. Thought I might use wi-fi, but discovered it would cost $10 per hour! Paid a lot for the flight as it was over the holiday period. Probably won't be doing that again.

Air Canada is the worst airline I have ever flown. They lost my luggage, cancelled my flight, refused to pay for a hotel, charged me for business class even though they changed my flight to economy and there is no process to get someone on phone. Would not recommend Air Canada to my worst enemy.

Overall it was great! Seats were comfortable. We were offered snack and drink on the way to Florida but only a drink coming back. Free messaging for aero plan members was a great feature to have on board so we can connect with loved ones … entertainment like movies and shows was also a good selection!

The problem in part was with the airports, not really the fault of Air Canada. Confusing directions regarding the gate, in Seattle the recommended shuttle train entrance was not working. Simular problems in Toronto. Baggage arrived in good time. Marx Bros movie on entertainment from Seattle. I was told I was laughing too loudly, by the flight attendant. No lounge in Seattle. Lounge in Toronto excellent.

Made me check my carry on despite there being dozens of empty bins when I boarded which significantly inconvenienced me.

I arrived for my flight and was told I was now on standby as my assigned seat when I purchased my ticket was just deemed unusable 15 mins ago. My parents had to wait and hour and a half at the airport to see if I’d get in the plane. Finally when all passengers had boarded the plane I was finally told they did have another seat for me. When I boarded I saw someone else sitting in my originally assigned seat. It was in the emergency exit row and has extra leg room. I have sat in this row many times and am able to help in an emergency so no reason for me to have been kicked out of this seat. The new seat I was assigned had no padding and was extremely uncomfortable. Upon landing my back was very sore and I will probably need to see a massage therapist to help ease the tension. There was no tv or way to charge my phone on the plane. Worst flight I’ve taken in a while by far.
