My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

Much better than the major US Carriers especially in Biz Class.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

It was not Air France but Air Europa. But confusion over our checked luggage. Whether it was checked all the way to Tenerife or not. It was not. Had to line up again in Departures. At least our Sky Priority was honoured. Flight was fine.

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

The male attended that served are section was a snob. He did not answer my call light when my wine spilled all over the floor. I did not push it again or drew his attention to it. He just ignored the call light when he came to give us our meal, serving the people behind us first. I did not push it again or drew his attention to it to see his reaction. It was so obvious that he was ignoring us. We were in premium economy!

Georgian Airways check in staff initially denied us, because they thought passengers required transit visas to transfer on connecting flights. This required 70 minutes for them to call multiple people to confirm how transfers worked. They did not apologize once accepting our check in. Onboard, the four hour flight gave stale bread with spam slices as lunch. The only included drinks were still or sparkling water.

I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.

Not a good one this time. The absence of internet without any information/notification ahead was really the unacceptable part. Also this new A350-900 has a serious legroom challenge for economy seats. It’s more like a medium-haul flight legroom configuration.

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.

The first flight was better in terms of the aircraft.

The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.

Very punctual. Comfortable plane and great entertainment options. The staff was very nice.

I completely missed my flight because the first leg was longer than planned. I had to sleep overnight in the airport because no accommodation was provided and then sent to Trinidad in the morning with an anticipated 7 hour layover before my flight to Georgetown which was now with Caribbean Airlines. I tried twice with customer service to see if they could put me on an earlier flight which had seats available but was told it wasn’t possible.

Overall great. I was forced to check my carry-on backpack from EWR to BOS but it came out on the luggage carousel so fast I didn't even get delayed for my pickup.

The plane was so gross and dirty. Literally saw dust layering and flowing out the grey vents. Dust was all over the air vent knobs to the point where I took my sani wipe and cleaned them down so at least it wasn't blowing my my face. Also, I upgraded and paid for Wifi and it's always so spotty. I get we are in the air, but don't charge for it if it's not going to work. I expect so much more from United. They really are giving up.

Haven’t used United in a while. Was surprised with the free blanket and earphones. Service was great. Huge plane. 9/.row.

It was delayed by almost 90 minutes and that messed up our plans but it was beyond UA’s control that is what we heard

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

Facilities and staff were great, but the company let us down. Just four hours into the flight, they ran out of ALL snacks. Perhaps this was the first time they ever did this run and had no idea afar might be needed? Or maybe they didn't know how many passengers would be abourd? Or did they just not care? (Oh, and the meals were very sub-par. One was so bad that I didn't finish it. )

In both directions, one of the two flights was delayed in departing. due to mechanical issues (not weather). That tells me that inspection and maintenance is not being done often enough to prevent such from occurring. In the outbound direction, the second leg was delayed and we had to change our plans for after landing, thus missing an expected event. In the return direction, the first leg that was delayed; we had a long enough layover that we were not hurried to make our connection, but others were not so lucky. Comment about this survey process: in the multiple choice answers, there is no option for "Not Applicable"; as we had no food on board, we can't properly answer that question.

The take off was delayed as we were told that the baggages had to be rearranged to balance the weight. I only took a carry-on and a personal item, but the overhead bin was extremely small, even a normal size carryon can’t fit it, so they had to check it in for free. The seat was really tight and no entertainment at all.

My plane was cancelled and had to be rebook for the evening was not happy.

every single person involved showed their joy, working in the airline industry - it created a very pleasant atmosphere for everyone

Flight was fine, 1st plane was a bit old entertainment, 2nd the display was freezing/ crashing every 30min. We had problems getting at gate and waited 2hr to get a gate in Toronto, then had a 90min mechanical delay at the next departure. Weather was bad and I’m just happy we didn’t get stuck.

Check-in, Boarding and Flight were fine however I unfortunately chose the only seat in the plane without a window (15A) and when I asked to move up to row 13 that was empty, I was denied because they call it a preferred seat. The only difference I could see was maybe an inch or two more legroom. I think once the door is closed and all passengers are aboard they should be able to accommodate a reasonable request to move even if to a seat they tried and failed to sell for more money. And a few flights now, I find that Air Canada’s Infotainment system has a 100 channels with nothing on. No movies still in theaters nor any that are not already streaming for free.

My wife was in a wheelchair. Most accommodating and kind staff!
