Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

Half the bathrooms assigned to economy were out of action

The crew was quick and efficient. The flight was uneventful and arrived slightly early.

My seat was broken I couldn’t put it back I have really bad back issues , the flight was 5 hours delayed and there was a drink dude harassing the entire flight

No food or entertainment because it was a short flight. Unfortunately the takeoff was delayed more than an hour

The flight left and arrived on time. the only food offered on the 5+ hour flight was a cheese sandwich. Unlike Alaska Airlines there was no information on the website regarding food at all or any option to purchasse in advance. Otherwise, it was an excellent flight.

Parents with kids should all be in the same area. Sounds rude but who what's to fly 6hrs with crying and bratty kids. Just my opinion.

Ok, so I didn’t have seats, so got there very early. I was first in line only to be told, listen for your name for seats. The flight was boarding before they gave me a middle seat, way after others showed up who were given more favorable treatment. Ok, so , don’t show up early and obey all the rules??? Clearly, your gate clerks did not. What gives???

Short flight but delayed. Since its a short flight no food or entertainment necessary

We had an awesome flight attendant who came by and made sure we were okay. Checked on us often and even shared some snacks that she had brought on, like edamame with chili and garlic seasoning. Yummy!

Overall good experience. I'm just over 6ft with long legs and legroom could be better, but is on par with other airlines. Only real negative was turbulence but that's not the airlines fault.

We were not given the seats we reserved. But helpful attendant at gate gave us very nice seats.

The international flight from Sydney to Dallas had great food. I have travelled a lot over the years and this has been the most memorable in my experience so far.

flight delayed, wait in crowded gate. staff inattentive. had to remind them to get my coat from their closet. not many new movies, media choices were limited (nothing compared to Emirates.) Lounge was crowded

flight delayed, wait in crowded gate. staff inattentive. had to remind them to get my coat from their closet. not many new movies, media choices were limited (nothing compared to Emirates.)

Initial flight was cancelled so moved to an alternative flight. As a result, stuck in a middle seat. Flight then place in holding pattern prior to landing resulting in a very late trip home.

There was nothing I didn’t like, prices a little lower would help

Flight delay was informed at the last minute. Food quality is not up to Qantas standard I was unable to book an online boarding pass on any of my 6 flights.

Following a marathon flight riddled by delays and changes from Santiago, Chile, my flight to Melbourne from Sydney was on schedule but I was transferred to the next flight. The reason by ticketing and the floor manager was I missed the entry to flight by one minute! That's right, the emphasised that if I was 1 minute earlier I would be on the flight. I asked what was the point them emphasising 1minute overdue and how that helped me or the situation. They didn't care at all. Replying that if it was one minute earlier they would've done something and smirking delivering the information. Australian's do call Australia home, Qantas calls Australian's suckers.

Rescheduled after ticket purchased and issued, not 2 or 3 times and not a fourth but by 5 times, by Qantas, that's right, 5 changes! Forcing an overnight stay in Chile and need for visa. Qantas can no longer provide basic services as a national or international service provider. Professionalism is extinct and the provider needs to be mentored and educated in perfecting who to operate as an airline. Qantas is the spirit of Australian dissatisfaction.

Amazing! Was put on the earlier flight and I requested for an aisle seat and was given it. Thanks Qantas!

The staff we fantastic and seemed to work very well with each other

Not worth the premium paid for the first class ticket

Not worth the price of premium class ticket paid, felt more like steerage.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

I flew Delta last week and United Airlines is a poor substitute mechanical problems with the plane and shitty food among other things made my travel experience what’s become to be expected from United no way is it ever worth the money they make us pay

I had a great flight. Everything went smoothly and the flight arrived early.

Well....let's start from the point that I had to stay in airport for 12 hours instead of 2 that was scheduled. Poor company and even worst customer service. Never again....

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

We liked the fully reclinable seats. Had center seats, so it was difficult to talk to spouse. Crew was great

Aisle chair was good and liked the foot bar preventing you from putting your foot in the isle, The breakfast on this international flight to Zurich was horrible (Europeans, specially, used to good food) may make this a dealbreaker for booking with United Airlines again. I agreed with my Spanish fellow passenger.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

No meal. Flight crew was wonderful, happily finding me storage for my guitar. THANK YOU!!!

My seat was moved multiple times. I picked out the perfect seats beforehand. I even paid extra money for them. However, I was moved to a middle seat without warning at the last minute. It was like my worst nightmare. But other than that, the actual flight was good. Everything was on time or even early and the flight was smooth.

A220 plane had 5 seats across which is great for couples who can snag the A&C seats. Seat itself is borderline comfortable but still tough on a 5+ hour flight. Overhead bins are small so if you're not in at least boarding group 5, you could be in trouble. No included food service. Non-alcoholic drinks are free but even the most basic snacks are for a charge. Price was reasonable for the only direct SEA-YUL flight. Boarding is efficient even managing passport checks. Worth flying for the direct flight.

The original flight from Boston to Toronto was canceled because of a mechanical failure. I was then scheduled on a flight to go from Boston to Montreal and then Montreal to Toronto. The flight was extremely full and I had to check my carry-on bag. When I actually got on the plane there appeared to be room for my bag. I understand the mechanical failures happen. But it was frustrating that they pestered me to check my bag when I don't believe it was necessary. Additionally, not just with Air Canada, modern airline seats are incredibly uncomfortable. There is considerable research that shows that the shape of them is poor for back health.

Unable to initiate refund/reschedule the ticket #worst experience #lost 900$

Flight was delayed for almost 3 hours. Communication of gate change was poor. Email and screen said one gate and it was a different gate from that. Gate changed first to 64 B and then to 64 C. Originally it was 68B. 64C was not communicated properly!

This was a red eye return, so I doubt there would be anyway to make it better. Other than adding beds.

Direct nonstop flight was great. Flight was delayed and the crew announced a 2h delay on the sound system. 30 min or so later I hear my name on the sound system for immediate board. Several other passangers were late too. Reason: The crew incorrectly announced a 2h delay when in reality they meant a new boarding time at 2pm.

Plenty of room in the exit row. Sat on the plane an hour before taking off.☹️ Landed late and had to wait for gate availability.

Flight was on time early arrival better entertainment good staff.everything was excellent
