Airline reviews

Pros: "Premier access makes a big difference in service!"
Cons: "Nothing"

Pros: "The seatback entertainment system was working today."

Pros: "Everything"
Cons: "N/A"

Cons: "Not having videos on plane in seat sucked! Mediocre over priced Food"

Pros: "Captain told the truth."
Cons: "UA should have had a backup plan rather than waiting."

Pros: "See above"
Cons: "see above"

Pros: "Staff was great"
Cons: "getting off the plane was very time consuming despite being already landed. Not entirely sure why but this was the first time getting off a plane took some time. im sure the staff was working hard but I’m unsure why it took some time."

Pros: "The flight was on time!"
Cons: "no complaints"

Cons: "Reputation of United makes you expect bad service"

Pros: "No complaints at all. Great flying experience"

Pros: "The United employee at baggage claim was quick to assist. She gave me a new bag to transfer all my belongings and a flight voucher for my damaged bathing suit."

Pros: "Overall it was a fairly comfortable experience."
Cons: "The United WiFi was not working on my device. I could not connect."

Cons: "Smelly."

Cons: "Flight was delayed and the female crew member was rude."

Cons: "long delay"

Cons: "Wifi didn't work"

Pros: "in flight entertainment"
Cons: "everthing else"

Pros: "What I did like was the courtesy that they gave me as a military to go in first in the plane it made me feel that my country really loves me..."
Cons: "Me as a military personnel giving my life and my soldiers for better and safe country I think all Airlines should not charge baggage to any military the only one that does charge is JetBlue sorry to tell you that but that also has to be improved something has to give to us as military to feel proud of our country...."

Pros: "No complaints"
Cons: "No complaints"

Pros: "They accommodated my 6 hour layover by reducing it to 2!! Got me home 4hrs earlier. So grateful."

Cons: "Our original flight was cancelled and on the rebook, which added a stop, my family of 4 which includes a 4mo and 5 yr old were all given separate middle seats. When we brought this up we were told only the gate agent could adjust. Although at the time there were seats together they were "economy plus." Not surprisingly the gate agent was very rude when we approached her with the issue, insinuated it was our fault, that we were extra trouble for traveling with 2 small children, and that we may have to be bumped. We were finally accommodated at the last second but it was unneeded stress. Also several flight attendants gave us a hard time for bringing aboard our infant car seat despite the fact it is FAA approved and we bought a seat for it and it is the current recommendation of the FAA to do so."

Cons: "I carry expensive equipment in my backpack and it's an accepted carry on but doesn't fit in the overhead bin of smaller planes. Can't afford to check it and have damage."

Pros: "We flew through some pretty turbulent skies but the pilot did a great job, and I saw that he landed in a strong crosswind when's i looked out the window at SAT, although you couldn't have guessed it from how smooth the landing was."

Cons: "Both flights were INCREDIBLY delayed. First, the flight from San Jose was delayed 1.5 hours because they were "waiting for the aircraft." After everybody finally boarded the plane an announcement was made that somehow the luggage crew had damaged the cargo hold, and that everybody would have to deplane. It would take 45 minutes for maintenance crew to arrive to assess the situation. People got up, got their luggage out of the overhead bins, and started moving to the front of the plane. The pilot then came back on the intercom and told everyone they would have to return to their seats. Roughly an hour later we finally took off. It would have been the decent thing to do to AT LEAST offer the passengers something (i.e. comp drinks or snacks), but the cheapskates at United DIDN'T EVEN APOLOGIZE. Multiple people missed their connections. Fast forward to IAH--> SAT. Another late flight. This time, everybody boarded the plane only to be informed that due to a problem with the plane's computer everybody would have to sit on the plane while they "rebooted" its computers. This was done TWICE. UNITED AIRLINES, GET IT TOGETHER. There is a very good reason you are consistently ranked one of the WORST US-flagged carriers, which makes you one of the MOST HATED AIRLINES ON THE PLANET. I really and truly pray that the US airlines and their lobbyists lose their battle to prevent foreign flagged carriers from operating within the US, because you all deserve to go bankrupt."

Pros: "Nothing"

Pros: "Ticket price"
Cons: "Long layover"

Pros: "I liked the size of plane didn't feel cramped."

Pros: "Great flight. Everything was on time and went smoothly"

Pros: "Arriving safely at home."
Cons: "Our gate was changed multiple times with absolutely terrible communication. The computer system had gone yet and everything seems extremely disorganized. There were even flyers getting on the plane to TX when they were traveling to other destinations because of the lack of communication and the crew not throughly checking. The seating was the smallest space in all of the other airlines I have flown. The crew was less than friendly and yelling down the aisle about buying snacks and other drinks although it was a late night flight and many people were sleeping. Overall, it was an uncomfortable and frustrating experience. Luckily the flight crew had a smooth flight and got us safely to San Antonio. Only positive about the experience with United. This was all taking place along with our flight being delayed with out the monitors at the airport being updated and no notification via text or the United app."

Pros: "It was on time"
Cons: "it was ok"

Pros: "Prompt and friendly crew."
Cons: "Not much leg room."

Pros: "Comfort. Economy plus was only $75 at check in. Well worth it for the leg room."
Cons: "They didn't offer pillows for a 4 hour non stop flight. I would have slept much better with a pillow"

Pros: "Professional staff"
Cons: "The departure gate was changed 3 times to terminals very far away. It was a bit tiring to dash to the different terminals in order to not miss the flight"

Cons: "How can united cancel my return reservation after they delayed my arrival flight forcing me to jump in a car and drive the 3 hrs I could have driven earlier that day! i choose to fly to make life easier but due to the service I would rather use a different airline or just drive to ensure I'll be at my destination on time."

Pros: "The boarding procedure was okay but my flight was delayed"
Cons: "I usually fly southwest...the flight was hot and uncomfortable, the a/c was blowing hot air thru the whole flight was very disappointed"

Cons: "Anything"

Pros: "The newness of the plane."
Cons: "My flight was delayed from 4:50 to 7:45 without any type of notifications text message or emails going out to any of the customers notifying them. I got to the airport and had to wait additional 3 hours that is horrible!"

Pros: "Boarding was quick"
Cons: "Arrived late....broken seat"

Cons: "We were delayed because they couldn't find the demo seatbelt. Then take off and landing were way too jerky. Also they claimed due to it being a short flight no drinks would be served, as we get to watch first class get everything."

Cons: "Flight was delayed 30 minutes"

Pros: "I liked the StroopWaffel. Was given an extra one by the attendant. The flight was quicker than scheduled. The attendants and pilot were very friendly."
Cons: "Our flights to and from Minneapolis were booked a few months in advance. On our flight from Den to SA, all three of us were in the center seat, in different sections. That displeased me."

Cons: "Very difficult to get to EWR from Brooklyn and the departure was changed 6 times that afternoon."

Cons: "Flight was delayed due to severl technical issues. Crew at least offer free drinks or snacks for the five hour delay."

Pros: "Had no issues"

Pros: "Comfort and great staff; smooth landing as well"
Cons: "N/A"

Pros: "I loved how quickly we departed and arrived at each destination!"
Cons: "The boarding process was terrible. People forgetting to even stand in line for their boarding groups getting to cut ahead of those whose group is currently in the process of boarding. That should not be allowed. It's rude and disrespectful to other passengers/customers."

Cons: "The landing in San Antonio was the scariest of my life. I honestly thought we were going to crash."

Pros: "Service was good"

Pros: "Nothing"
Cons: "Food was free but horrible and u had to buy your alcohol"
