Time to upgrade those planes so you can provide first class.

The flight was smooth and on time. Entertainment options were lacking and there was no food, other than some very boring snacks.

A better selection of entertainment would have been nice. I found nothing that appealed to me as a middle-aged traveler. The flight attendants were gracious, helpful, and attentive. It also would have been nice to have more bathrooms as the flight was full and the plane was big.

This flight was the second leg of a trip that began in Auckland, New Zealand. I was unable to find a way to select seats in advance. The boarding passes we were given in Auckland did not have seat assignments for the second flight. There was no way to check on it until personnel showed up at the gate in Los Angeles, immediately before boarding time. The flight was overbooked by one, and since I was traveling with my sister, we needed two seats. We waited in considerable anxiety for everyone else to board and when one person did not show up, we had to take whatever was left. At least we finally got on the flight although we were the very last to board. We were not able to sit together, of course.

The Premium Economy seats were very comfortable and the food was quite tasty. I did not use the entertainment system, but I was able to charge my phone and tablet with the seatback connection.

Air New Zealand over sold our flight and tried to bump us to yesterday. After several calls we got booked to United about 6 hrs before our original flight. No apologies!

Do the bumpy weather the whole trip they were very few times when the seatbelt sign wasn't on

The staff and crew on board were excellent. Business class however, was very weird. I thought we would have individual pods, but the way it was set up was unexpected. Not very private and If you wanted to lay down, you had to have an entire bed made up for you by the crew, rather than how Delta one works where you could just lie down whenever you feel like it. It was a 16 hour flight. I chose not to have my bed made, and that turned out to be a good idea because everybody who had their bed made had to wait for the crew to roll up their mattresses. So strange!

Couldn’t request a vegan meal somehow but I noticed other people getting them

Carring crew, nice ambiance of the cabin, comfortable beds, good food well served. We liked everything.

Having the computer outage compounded by delayed takeoff while waiting for aircrew (who were also delayed) resulted in me missing my int’l flight

My flight with Qantas was excellent, the crew were exceptional, the food was very good, and the seats were surprisingly spacious and comfortable. I was extremely disappointed when my checked bag did not make it onto my connecting flight, but was pleased with the ease of filing a report of a missing bag with Qantas at the Auckland airport - there, my pleasure ended. I can see, with an apple tag on my bag, that it is still in Sydney and has not moved in more than 30 hours. I shared the tracking information with Qantas and was assured when I filed the missing bag report that my bag would be delivered first thing the next morning on the next flight from Sydney to Auckland. Qantas' missing bag tracking feature still lists its status as "searching for your bag, check back later" more than a full 24 hours after filing the report despite my having shared tracking information, a photo of the bag, and calling the customer care line and being assured that an "urgent action message" had been sent to the team in Sydney. The lack of communication from Qantas' customer service department and the lack of action after an incredibly expensive business class ticket price is outrageous and has, definitively, affected my willingness to consider flying Qantas in the future, much less on long-haul international flights with high cost airfare.

Very good overall. Highly recommend for all flying to Australia

Our boarding and flight was very good. However when we landed and pulled in to the gate it took 55 minutes for the jet bridge to be positioned next to the aircraft. That caused us to miss our ground transportation and it caused us unnecessary last minute transit planning and expense. Our flight was AA1733 on March 17, 2026

Business seats not as comfortable or private as most competitors (e.g. Qantas was outstanding), and movie selection was much more limited than Qantas or United has been recently

One of the oldest most uncomfortable "lay down" seats I've ever experienced. Old plane and old seats that don't lay flat. The seat back does not even recline - at all. Instead the legrest awkwardly extends to fill the gap between a small cubby into which you must insert your feet/legs. I am 5' 11" and could not lay straight but had to tuck my knees. Ticket was also very expensive. Would not recommend flying business/first on Finair from Melbourne to Bangkok and will not do so again myself.

Our baggage didn’t arrive with us on the plane. Need I say more?

American Airlines was their usual junk service — but at least it got us down to LA. I was more irritated that while they codeshare with Alaska Airlines in Seattle, they could not out our flight on one of these, opting for one of the small SkyWest operated American Eagle flights — and causing a 14 hour layover. Which I accepted due to a $2000 difference in airfare — that said it was irritating for a flight that usually would have cost around $100 extra, if that.

Better food, hotter coffee, otherwise it was a very smooth and reasonably comfortable flight.

First time flying in Qantas. There is zero WiFi on the flight to/from Australia. Crew was great both routes - very attentive, personalized service. Pleasant staff throughout.

The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

The website check in was poor. Baggage fees were in US dollars but registered in Canadian dollars. The site would not accept my credit card. Scanning the passport was the worst. Someone from United needs to try the process. I’m not a novice with tech and I have to say this was a bad experience. Everything else was great.

Flight was late, the only reason I almost missed my flight was that my connection was also late.

Lufthansa seats were much more comfortable than United. While they had about the same video selection, Lufthansa didn't put advertisements in with the movies like United did. And the Lufthansa food was much better than United.

We flew business fares. Was amazing. However, the check in didn't offer business fares preboarding which is less hectic. 8/10 due to this. Staff compared to Canadian carriers go above and beyond. Would gladly fly United again.

The staff was incredible, very attentive, polite, made you feel like the center of the universe. They even all wrote me a happy birthday card. Truly just an amazing crew, cannot stress it enough.

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

Boarding was smooth and efficient. The only food was some pretzels, but it was a short flight. Not much to order if you were hungry.

Everything was delayed and the staff sent me to the wrong gate, causing me to miss one of my flights. I arrived at my destination 6 hours later than I was supposed to.

On the return flight, arriving in Denver we sat on the tarmac in Denver for over 20 minutes.

The flight was fine. It's the satellite terminal that supports American eagle flights is what sucks. There is only one food option and everything there is way overpriced. I mean I know it's airport pricing, but it's even crazier than that. I bought a sandwich in a plastic container for $18.

Don't change gate multiple times make people run across the airport. Announce delays in a timely manner. Have maintenance crew ready. Don't delay and keep passengers on the plane for 3 hrs. on tarmac.

The flight attendant use 1.5 hours to answer my call. My dirty food tray was unattended.

Our bags took a long time to get unloaded once we landed.

Terrible. The flight was delayed two hours due to weather. Then when we got on the plane, the first pilot ended up timing out and we had to wait for a second pilot. Second pile came on board and we tax it out. Had to return back to the gate because of an unruly passenger. Then the copilot timed out. Had to wait for new copilot. Also had to wait for maintenance to check for fuel. Then found out the second pilot timed out and we had to wait for a third pilot. Was ready to go and then needed maintenance again for another issue. In the end, it was 2 o’clock in the morning when they announced that the flight couldn’t go because the third pilot and the second copilot had timed out.

One of the best flights I’ve had. So smooth.

Because I can’t stand very long in one place, I was allowed to reword.

Flight to Phoenix was delayed 1 hour and was not weather related. Flight Denver was delayed 2.5 hours and again was not weather related as the plane came from San Francisco.

Another good flight experience with Air Canada. The business section did not feature the full length sleeping arrangement, but this was a shorter trip. The food was excellent. But the flight crew was truly top tier: friendly, cheerful, helpful at all the right times. Air Canada truly outshines all U.S. carriers.

Wifi was great. Kind air crew and comfortable seating. Also liked the entertainment options.

I did not noticed baggage was separate - I had assumed international flights included luggage, so it surprised me I had to pay to check a bag.

In a nutshell, my bag, the one I have to pay for, because now you can’t even bring a carry on, did not make it. I am still waiting for an update. The fact that not only were have to pay for it, but on top of that we are stuck without getting it, it’s ridiculous..

flight landed late almost 1.00hr and we 4 passengers missed our connected flight to indianapolis, we need to get the hotel and taxi for the next day flight to home in indianapolis, cost us $ 300 more

Overall good experience. The flight from Toronto to Denver does not have entertainment - movies to watch.

Staff was friendly helpful also good timing I rate it a 10 out of 10

The only issues I have are the seats are very small and so is the overhead storage. You should mention that while booking flights. I had plenty of knee room but I am wider than my seat, and I am not fat at all. The Mitsubishi 900 models need to be upgraded to western size people. I do not know how a 300 pound woman fit into those seats. I had to continuously lean away from the aisle to keep people and flight crew from bumping into my shoulder. 3 hour flight so no entertainment or food, just snacks and a drink, which was no big deal. The buttery/garlic pretzels were pretty tasty.

I was overcharged either by United or sister airline Air Canada. It's exhausting dealing with companies nowadays that irresponsibly abuse access to credit/debit cards.

The Air Canada agent was very helpful helping with my luggage and cat carrier when I went there instead of United.
