Pros: "Everything was pretty smooth, on time, as expected, no problems."

Pros: "i arrived alive"
Cons: "My flight was delayed on the way to Puerto Plata on 9/9 which made me miss an entire day and I was billed for a stay at the resort. I was booked to a crappy room in MIA that I had to get changed to another hotel. THEN my departing flight from Puerto Plata back to the US was delayed 2 plus hours (as was the first flight) due to a flat tire that had to be replaced. I missed my connecting flight and had to be placed on the next flight to DCA which was the last flight. This experience was the worst. I do not have a favorable opinion of American, of which I have flown this airline for years."

Cons: "Didn't know about close connections and terminal changes until printing boarding passes. Snack offerings are minimal one almost all airlines for regular fares. a tiny wafer cookie or about 5 mini-pretzels are not very impressive. I wold much prefer peanuts to pretzels--an option would be good. The gate of outgoing flight to Bloomington kept changing on phone m messaging shortly before takeoff , about 6 gate changes in 10 minutes. Confusing!"

Pros: "Crew were nice; movie selection was very good"
Cons: "It was so so cramped, and the area under the seat in front of me had a support/leg of the seat in front of me right in the way, so I couldn't stretch my legs nor store my bag there. Such disastrous design."

Cons: "Unable to sleep, too uncomfortable"
Pros: "Customer service and everything else was great"
Cons: "Getting delayed. We were supposed to leave at 10 something PM but instead kept getting delayed until we finally left at 1:45am.

Cons: "Screen small and blurry"
Pros: "My daughters entertainment system didn’t work at all, so they graciously compensated us for the inconvenience."
Cons: "Entertainment system was outdated, extremely small screen and the audio wasn’t that good."
Cons: "I landed in Terminal 5 at LAX, so I walked 20 minutes to the International Terminal and waited in line at the Austrian Airlines counter for 45 minutes. When my turn came, I was told that Austrian does NOT fly to London. After a while, they figured out I was on a Unites flight, so I had to walk to terminal 7 (about 25 minutes) to check in with United. If this is a United flight, why is it called Austrian Airlines? Very frustrating and confusing to me and to Austrian Airlines!!!"

Cons: "Need to upgrade blankets th something that could actually provide warmth."
Pros: "Crew was courteous and food and snacks were good."

I also had to remember to write down the number of that bin so I could retrieve my carryon at the end of my flight.Toilet was not very clean."
Cons: "board . The door was closed & we waited for 2 economy passengers - took an hour . mY experience - once the door is closed , it does not open until the plane reaches the destination ."

Cons: "no vegetarian óption for breakfast"

Cons: "Three hours delay when all aboard already due to “technical difficulties” and then we had to change plane. The whole entertainment system did not work. No apology or explanation."

Cons: "I can't blame United for this, but we had to circle around Heathrow a couple of time and even had to perform and emergency pull up because there was an airplane still on the landing strip."

Cons: "My connection was clear across the airport, it was quite the trek when the second flight was already boarding"
Pros: "The airport location was convenient."
Cons: "Flight delays up to 11hrs. Poor food. Poor flight crew hospitality."
Cons: "I was dreamy disappointed when I purchase the ticket I thought I was going on luthhansa Airlines instead, i was on United Airlines which had a old 747 back in the 1990's it was dirty and uncomfortable. When I made the booking on kayka there was no indication that United Airlines was going to be substitute Airline"
Pros: "Food was ok - but served way too hot. Crew was pleasant and the entertainment was a decent selection."
Cons: "When we arrived, we were told we weren't actually taking Austrian airlines and should have been on united - which was at a different terminal. Then checking in was a disaster - neither the Austrian app or united app would allow me to checkin. Then the seats we had selected initially weren't given to us at checkin so we had to upgrade our seats to sit together. And then, in our more expensive seats - we froze. We were underneath the AC and the crew said they had no extra blankets."
Pros: "The worst part of my experience was the rudeness of the crew."
Cons: "They were late."
Pros: "Flight was on time, except that we had to wait a few minutes for more oxygen to be boarded because the flight was completely flow (overbook in fact)."

Pros: "Polaris is a great product"
Cons: "Crew still stuck in their old ways and don't deliver personal service, just wait your turn trolley service - when they spend most of the time chatting in the galley!!"
Cons: "HUGE DELAY. MISSED CONNECTION. CONSTANT UNCERTAINTY"
Pros: "Entertainment options were varied and kept the flight interesting."
Cons: "The check in process did not allow us to select seats until we got to the airport so we had to sit separately."
Pros: "That the flight came in to London 30 mins sooner than its scheduled time."
Cons: "Terrible behavior by the crew. It felt truly humiliating to be spoken to condescendingly by them and treated very badly."
Pros: "Lots of movies and shows plus constant tracking info."
Cons: "Closeness of seats and worn out touch screens on seat backs resulted in people behind us constantly kicking and pounding on our setbacks throughout the flight. Cleaning crew did not do a thorough job, leaving trash and used chewing gum on floor from previous flight."
Cons: "My 3rd old was very hungry and I reached out to cabin staff for any kind of food for purchase, they turned me down saying I need to wait for another hour till the dinner time. Did not provide any help there. My baggage did not reach with me and they promised to deliver it with in next 6 hours and it turned out that they took more than 18 hours to deliver my baggage to my home. My entire day got wasted waiting for this baggage to reach me. Poor communication made me wait and watch the door every hour. I tried to reach and get some information on when that baggage would reach me but no body knows."
Cons: "8 channels of looped shows and movies. Too long a flight for that...and then have to use my device to watch on the free part of the wifi.so no battery left. For this price? And I booked through Lufthansa but flew United. Bad form."
Pros: "The trip had minimal turbulence. The landing was smooth."
Cons: "-The 767 was old. -It did not have any power ports for my laptop or cell phone. -The interior was old and dated, reminiscent of the 1980's. -The TV screen for entertainment seemed to be smaller than a Samsung Note 5. -The seats are unreasonably narrow and not comfortable. -I had an isle seat and my shoulder width is literally wider than the seats. -Every time the isle cart went by, it hit my left shoulder. -The seats in general seating are too small and were cramped. -God forbid if we had to egress out of the plane. -There were no adjustable head rests, like other airlines have. -The Flight Attendant for my section DID NOT make me feel like I was a valued customer, even though I paid over $1500 for flight. -She scolded me for asking "Why," when she TOLD me that I needed to sit in one seat, even though the seat next to me was vacant. She literally treated me like a child. - NOT COOL. Overall, in comparison to my last international flight, I WOULD NOT recommend United. I feel like I paid too much for my experience with United. Aer Lingus has better/newer aircraft, better cabin crew, better entertainment selections to include music and a selection of movies to watch at your convenience, more comfortable seats, provide a better environment, and a better value for your experience. Aer Lingus was also cheaper. So if you are reading this, please shop around if you are considering United to fly."
Pros: "I was upgraded to economy plus aisle seat"
Cons: "Flight delayed about 1hr"
Cons: "Bought the ticket with Brussels, but it was operated by United. Late departure. When we boarded, we found that United had booked another person in my assigned seat! Had to stand in the aisle for nearly 10 minutes while attendant found another seat for us, farther back in the plane and in the center section. Absolutely no legroom and the food was hardly edible. Every few years I fly United in the hope that they'll have gotten better, but it just never seems to happen. Still can not recommend this airline."
Pros: "Getting off"
Pros: "There was nothing to like about this constantly delayed flight with rude attendants at the gate. I will not be flying United again."
Cons: "Everything! Our flight started with a thirty minute delay which was mentioned after we were asked to stand and prepare to board. The flight continued to be pushed out an hour every hour with no reason as to why. Our gate changed and we were told to line up for boarding, then we had another delay. The frustrating part was being told to line up to board only to see another delay. In total, the flight was delayed over four hours, being asked to prepare to board three times and with one gate change. This was not even the worst part, our new plane did not have WiFi, which was promised when booking. Needless to say, the entertainment was bleak. The icing on this flight from hell was when we hit turbulence and two bottles of wine spilt on another passenger and all over the floor. I understand that this happens, but none of the flight attendants attempted to clean up the wine and all the passengers where forced to smell cheap red wine for the remaining eight hours of the flight. I regret to claim that I will not fly United ever again."
