Avoid Toronto airport if possible. One had to leave the airport to go to the next terminal. No directions.

If flying to Ireland, the direct flight from SFO to DUB on Aer Lingus is the way to go to avoid the hassles and uncertainty of mid journey stop-overs.

Look at Jet Blue and Delta. May be a bit more expensive but keep an eye out for fare reductions and book early.

Some people may be required to check their carryon bags, depending on flight, plane size, check-in crew, etc. Also, taller people should purchase aisle seats.

Whatever airline you choose, spring for a class with more leg and overall body room than economy (or whatever the cheapest class is called).

Eat and drink before boarding. Snacks. Hand gel and surface wipes . Don't expect a window if in a window row.

Go to the airport early, LAX is the worst airport to fly out from. There is just so much traffic on the way to get there. We used the flyaway option in van nuys, ( buy your parking ticket in advance) costing us only 115 dollars for parking for over two weeks and it’s very secure. The buses go every 15 minutes from there directly to LAX. Best way to get to and from LAX. Check in was easy.

JFK is an amazing airport, they have TSA precheck which was not offered when I flew Aer Lingus/Newark. The TSA precheck line took a long time, they only had 2 machines and a few agents working. Other than that Newark was as any other airport, easy bag check in process and gate seating area was clean and comfortable.

First time flying with UA and it was a great experience. Thank you

This was an older airplane. The cabin was constantly warm to hot throughout the 10 hour flight and there were no vents to personalize air flow. Also since it was an older plane, the material and comfort of the chairs were very uncomfortable. I left my flight with major soreness on my tailbone.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

Onboarding process was great and efficient. Plane was very new and entertainment choices were great. The only complain is no meal despite it was a flight that is longer than 6 hours.

First flight of the day… MINIMUM FUEL! 15 minute landing delay at HOU due to fog turned into a 2+ hour delay! Rather than circle, they had to divert to another city to refuel! Sat on tarmac at Austin to refuel. We ALL missed our connections! The crew, including pilots, were clueless. Crew was really a mess. At HOU, Untied employees were exceedingly rude to all. It was pitiful.

Pretty turbulent, but not anyone’s fault. They got us there. Impressed that they carried on with a drink service.

Again a nearly five hour flight and pretzels is all the food you get and all you can drink water. No electric plugs in economy. Staff was totally not caring. Delta next time

Flight attendant was on her phone the whole time, couldnt even get a water refill. It was an old plane, no entertainment no Wi-Fi.

Faster charging ports but that’s a super minor complaint.

Check in was excellent. Signs were easily understood and everyone was helpful. Everyone we spoke to was helpful. The crew was excellent.

I didn’t fly because the airline canceled my tickets on the last minute..

The check in and boarding process was smooth, and the flight was fine.

We had a wonderful experience with Aer Lingus. The seats were too close for the long trip. The crew was absolutely perfect. They were so caring and thoughtful! My husband did not have a good experience with Air Lingus on the phone when trying to take care of getting better seating because he is disabled and needed a wheelchair prior to the day of our flight! Mariam R. in Boston was so helpful with seating and getting help for my husband. Filip Pytka who works for OCS was extremely helpful! He made sure that we had the lift because my husband could not climb the stairs to get onto the airplane. He took us from the gate all the way down to where we needed to be.

Aer Lingus App never showed the gate and the board did not update until very close to the time the gate was due to close. Both planes departed late but no announcement was made which would have saved a run for the gate.

Flight delayed 45 minutes almost caused us to miss connection to transatlantic flight.

Vegetarian food options were pretty tasteless. Gob of rice with absolutely no protein, barely any vegetables, and poorly seasoned. Food was the major disappointment of an otherwise good flight experience. However, food is a differentiator on long haul flights.

We were an hour and a half late, which caused my rental car company to cancel my reservation. We had no car, had to take a taxi to our hotel, and then a taxi back to get a new car the next day. Sometimes lack of on-time performance can end up costing the passenger a lot of money, none of which is covered by the airline that operated the late flight.

Overall good experience. But seats were small and uncomfortable for the price. Good entertainment, staff friendly and attentive.

Missed the connection due to previous flight delay. Can't rate a flight I was not on

Plane should have entertainment, instead of people paying to use wifi

We are experiencing more delays with westjet than other companies. West jet used to be our favorite airline.

We booked a ticket with Budget Air and the receipt said economy. My older teen daughter is neurodivergent and took a carry on bag since the ticket said economy, but she didn't see that it said no bags on her boarding pass. She has low attention. She managed to fly from Prince George to Calgary. At Calgary, she was preparing to board her last flight and the women said you can't get on. She said you can't board unless you pay for those bags. She had a small backpack, purse and carry on suitcase. She said you have to pay $160 +. My daughter has trouble understanding. She said can you step out of line to think about what you want to do. Then she said we have to leave you'll have to catch another flight. She called me in tears. I asked her to pass the phone to the agent. She said the agent was refusing to take the phone and ignoring her. I finally calmed her down enough to politely ask the woman to take my credit card. I told the woman of my daughter's challenges and need for extra helps. All she did was lecture me on how we booked ultra basic and we should have checked. She took my number and charged my card. Then I heard her push the phone back to my daughter and tell her to get on. My poor daughter was scared and confused and had to fly in tears. No apologies.

Flight was re-scheduled for the next day. No voucher for a hotel offered. Boarding was delayed by almost 1 hour. No free meal or even water was offered on board. When tried to purchase a coke, was denied because they didn’t accept coins less than 1 euro denominations. A young male flight attendant was especially rude and unhelpful.

WiFi was not working. Zero entertainment. Did not receive a discount etc to make up for this.

Travelled with my mother in law and made sure she has wheelchair access. Very efficient travel. There was always someone waiting for her when she got off the plane

Flying is no fun anymore. Too little space. Too much carry on baggage slowing down everything.

It was fine. I had a lot of trouble trying to buy a seat. The Westjet website charged me and then didn’t give me my seat. I ended up keeping the seat I was assigned and hope that the charges didn’t go through.. they didn’t. But this problem with the website (trying to purchase a seat at check in) has happened a few times before. But overall the flight was good.

Great flight. Pilot was able to fully make up the 42 minute late arrival of the aircraft for an on time arrival in Toronto.

Food abd wine was good and for the price this was a true bargain, relative to other transatlantic options. But it is still significantly behind my experiences with Air France long haul in both hard and soft product. But for the price air Canada to Europe from Vancouver is currently the best value of quality for the dollar cost.

My experience was good with United too But only not so good thing was that at Calgary airport I was not given lounge access despite of flying business. Aspire lounge denied it to me, which was unfair I feel

Very good except paying twice for seat selection. Once when I booked and again when I checked in.

Food is terrible....... need better snacks, too. Crew was lukewarm.

We did not have seat assigned until almost the very end of boarding and my husband and I did not sit together I don’t know why even though we bought tickets 3 months in advance and checked in very early. We were not standby and we were treated as we had stand by tickets. I will never fly Air Canada again.

We had delayed flight and I arrived 2 hrs late But I got safety destiny

I missed that flight because Air Canada did not send my luggage which caused delays at Customs

Missed connection by a couple of minutes. I’m hat was followed by 2.5 hours in line for a hopelessly overmatched customer service desk that actually closed after 75 minutes and directed us join the back of another one at the other end of the terminal. Gross and truly remarkable levels of incompetence with Air Canada. Buyer beware!

A very convenient, direct flight with no issues and comfy seats.

Seating is very tight. We were delayed 90 minutes to board, because the flight crew were late

Waiting area not big enough for all the passengers, no airport lounge.

Really appreciated the care, attention and friendliness of cabin crew. Very comfortable, prompt and efficient flight.

People were nice. Seats are so cramped my knees had to be pressed into the seat in front of me.

Dreadfully long wait for bags at Dublin coming off an already late flight.

Flight was delayed and there was boarding pass and flight information errors resulting in confusion and stress

Aer Lingus was the actual airline so they handled everything professionally.

Economy extremely cramped. Dinner was not good. Breakfast was quite good. Crew was excellent.

Excellent service smooth flight f or the most part food was right now.I'm expectedly good.

The flight was delayed, and delayed some more. But there was more room on this plane than the one that flew oversees! There was no food or entertainment, but that’s ok, it’s a short flight

Was delayed for checks after evidence of bird strike, good call
