Premium economy seats and food we're very nice although the price could be more affordable so we can do it more often.
10.0 ExcellentSharon, Sept 2026
Premium economy seats and food we're very nice although the price could be more affordable so we can do it more often.
mechanical issue, so delayed take-off (hence the low boarding rating) and made a number of people miss their connecting flight. Also took a long time to get our checked baggage. I luckily made mine with 5 minutes to spare, but it was nerve-racking.
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.
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.
We sat on the tarmac in Denver for over 30 minutes because a plane was in our gate. The pilot kept saying it will just be 5 minutes or less. However, we sat for over 30 minutes. Experiences like this make customers not trust what the pilot is saying.
Service was slow Flight was very loud at back of plane
I need to note that this flight experience was generally fine but the boarding situation was absolutely a mess and there wasn’t any actual priority boarding. I rated the experience poorly because I’m am genuinely so frustrated with the crew on United taking the baggage space in first class. This flight it didn’t happen, but the last few flights (when I ironically don’t get an opportunity to provide feedback) have been spoiled because upon entering the first class cabin as one of the first few seated passengers, the overhead bins are full and ‘crew’’ tags are on the bags of those taking space. I don’t intend to infer some sort of a class or caste system but it’s absolutely ridiculous that the crew takes the overhead storage above and beyond their most loyal and lucrative customers. They should not even have economy space IMO. And I’ve gotten grief when I’ve noted to the crew the ridiculousness of the notion that the crew (who are the last off the plane) should have priority over flyers who pay. I hope you find a way to convey this message to United because it’s happening with increasing frequency and I intend to find a way to expose the specific crew members who are doing this on a flight by flight basis. (And I have a day job)
Seats needs to be wirer and food is very poor
Pretty much the exact same comments for this flight, there was crazy weather!
I have been flying united for a long time but now I’m done
1) United economy seats barely recline. 2) I have yet to get United WiFi to work, after numerous flights.
Return flight was perfect. All on time and no hiccups. However, going was another story. I don't blame United for the weather, but I am rather disappointed in its response to my getting stranded in my layover city for the night. United gave me a $20 food voucher. That's it. But besides this policy, the employees were incredibly helpful rerouting me to my final destination in Fort Lauderdale, FL. So overall, 8 out of 10. 10 out of 10 for flight comfort, inflight service and before flight service. 5 out of 10 for layover handling.
Santa Barbara is a super small and easy airport. Breezed through rental car return, breezed through Security, ordered a coffee and muffin and to my gate in less than 30 minutes. Maybe because it was a small airport we got the oldest plane. Hardly any overhead space and absolutely zero internet. Its NFL Sunday man! That hurt.
There were no vegan options for first class. Even though we were promised the satellite internet for free, we received NO wifi at all. Even though we were promised a 20-min early arrival, we ended up over 30 mins late.
After we boarded, we sat on the tarmac at least a half hour. Not that big a deal really but kept me from giving the survey an excellent.
Staff never asked passengers to bring their seat backs forward during landing. Was hoping to get a little relief from the passenger in front of me (I have long legs that I cannot stow in the overhead). Otherwise the flight was very pleasant.
We were told every hour that the flight was delayed until finally late in the day the flight was cancelled. We had to wait in line over an hour to finally get another flight. Once on the flight the host was ridiculously incoherent in the loudspeaker in flight - very inhospitable. Not happy with our experience.
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.
The Air Canada agent was very helpful helping with my luggage and cat carrier when I went there instead of United.
My feedback from the trip to Columbia to Chicago was meant for Chicago to Denver.
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.
