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

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.

Everything was the best it could be. Crew found me with pre- ordered food. Excellent experience!

Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

Lost of requested seat assignments. Lost my husband's meal choice

Late- that’s what United does best. Missed my connection, rebooked to a flight 17 hours later and had to spend $500 on a hotel. What did I get? A $15 meal voucher. What can you get in an airport for $15. I hate United so much.

Flights were on time actually early service was good and crew cheerful

we did a return flight from Paris CDG to SFO. This trip was much better than the departing flight SFO to CDG. The food was better quality, the crew was nicer, and the interior of the plane seemed cleaner.

Flight to Japan was was better across the board than the return to USA. Entertainment: Movie selection was old and not to my liking. Way too many woke choices. Not enough selections for sports or drama. Service: some of the crew were great. Not all. I paid for business class. a premium. Some of the crew thought they 'had' t do there job instead of wanting to serve and be polite. Food: Way to Japan was good. Way back to USA bad. Boarding: Wat out did not offer Business only; had to go thru general. If you pay for business, you should get business perks. Suggest you look for other than United for travel to Asia

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

I just think it’s unfortunate that Airlines have completely abandoned the idea of serving any kind of decent or even real food on flights, not even on a four hour flight!? Those days are gone, I guess.

Aircraft was noisy, old and never dimmed the lights on a night flight even on business class! I flew 17 times on United and probably another 40 on other airlines United USA /Europe flights were the worst to include luggage delayed once going to europe and once coming back

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.

Flight was delayed no information given really . No food whatsoever on the plane . I think you should be able to put that on the app so people have a chance to buy food bring it with them . They said plane was very busy on way over but there should be enough for both flights as we pay full price for the service. No information or very slow on the app about the delays . Staff were lovely it’s not their fault so company not fare to passengers or staff .

Smooth quiet flight take off and landing both excellent. Food was mediocre. Boarding at gate was disorganized and unacceptable.

My only complaint is that during my 8-hour-long flight, the flight attendants came around with the coffee and tea cart twice instead of the alcoholic beverage cart. I would rather sleep on a plane than rush to the bathroom to take a dump. I asked the flight attendant if I could have a beer instead of coffee or tea. Unfortunately, she said the bar is closed. That tells me that she was too lazy to get me a beer on the plane. I was not happy about that.

Caring & friendly crew. Most important: got us SAFELY to our destination!

Friendly flight attendants, decent food if you can eat dairy.

Could not make the flight. No one would help us at all

Flight was good, crew was excellent. No complaints at all

Friendly, professional. Everything went smoothly and pretty much on schedule.

Leaving the same day as planned would've been better

No internet, not even westjet connect makes for a boring flight

Our first flight from LAX to Winnipeg was changed but you never informed us at all. It went from a nonstop flight to a stay at Calgary. This impacted our trip negatively as we arrived much later than we planned to. Our returning flight was horrible. The flight was delayed 6 hours!! And we were NOT going to wait that long. The only way we got on our original flight was running there. However all of our suitcases were now coming on the delayed flight. It was the worst experience we ever had flying. I want my money back.

Be on time late arrival missed connection arrived five hours late to destination

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

Everything was good except I was a bit disappointed that I had to pay US $150 for bags.

They cancelled and moved my flight with no email or text or any other notice. I discovered this only when I attempted to check in for my flight. Actual flying experience was above average.

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.

Flight crew was great, and even the crew for checking bags! I had a question for a friend of mine flying tomorrow and the man I talked to was awesome and answered my questions and looked up things for me when he didn’t have to! I was able to give her current & accurate info for her flight and she was so appreciative too!!

Boarding was extremely challenging, long lines and wait time, almost missed my flight.

Flight from saskatoon to toronto was by far the worst flight ive ever been on and roughest landing ever.

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

Great setup on both flights except the last flight we got condensed dripping all over me in the last 20 mins of the flight

Super experience. Earlier than schedule departure and arrival. Baggage handling was very good

Real smooth and easy, Real good leg room in coach!

The flight was delayed for 2 hrs. We were changed to a smaller plane, which was shaking a lot.

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

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

Flight was good but temp in the cabin was cold.

Good flight, no turbulence. I felt safe and comfortable which is really important when I am just a passenger.

The seats in Premier Economy were very comfortable. The food was better than average. The way British Airways handled our seating was atrocious.

It was not British Air, we were put onto Air Portugal for our London to Lisbon leg.

Smooth flight. The seats were comfortable but the reclining mechanism didn't work very well. My wife's seat required the flight attendant to push the seat forward while she pushed the button. The leg support didn't want to return to its home under the seat. I ordered the diabetic meal which was full of carbs. It was low in sugar but carbs turn into sugar so was it really diabetic? Overall the flight was pleasant, long but pleasant.

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

Economy seats were good and spacious. Much better than virgin by a mile.

My seat cushion was poor. The cushion was compressed and was uncomfortable for such a long flight.

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