Pros: "Crew was very accommodating in light of the maintenance delay. Especially for those of us with small children."

Pros: "Very friendly crew."
Cons: "This is a small airplane. I would like to see United insist that people check large bags."

Pros: "It’s existance. Informative capt."
Cons: "Late almost 3 hours. Sketchy bev service. 50 seat RJ."

Pros: "Boarded on time. Smooth boarding. Departed on time. Landed on time."

Pros: "Nothing was good about this airline with the exception of the baggage crew that finally helped me in Washington Ronald Regan Airport"
Cons: "My flight out of Portland was canceled and it took hours to rebook. I had to fly American Airline to Washington DCA where I roamed the airport at 9pm looking for someone from United. The crew in Portland ME told me the gate person would have a hotel for me.... The baggage crew had to help me."

Cons: "I only made it as far as Chicago, and my bag was fairly comprehensively lost as I did so"

Pros: "Quick boarding, departed on time, arrived early, good cabin communication"
Cons: "This is a very cramped commuter jet, just one flight attendant to serve entire plane, she came by once for drinks but not a second time"

Cons: "Was delayed at take off and was getting claustrophobic sitting in the plane for an hour before a five hour flight."

Pros: "Boarding was organized and prompt. Crew was fantastic."
Cons: "Flight was to short."

Cons: "Person at ticket counter was rude did not want to wait in us when we was 1st in line. Did not greet and say good morning"

Pros: "AT THE TERMINAL IN PORTLAND THE ATTENDANTS WERE SUPER HELPFUL AS I WAS CONFUSED ABOUT GETTING MY TICKETS."
Cons: "JUST BEFORE BOARDING THOSE OF US PASSENGERS NOT ALREADY BOARDED WERE TOLD WE COULD NOT BRING OUR CARRY ONS WITH US AS THERE WAS NOT ENOUGH SPACE TO STOW THEM OVERHEAD. SO WE WERE TOLD TO SEND THEM DIRECTLY TO OUR FINAL DESTINATION. WHEN I BOARDED THE PLANE I COUNTED 7 OVERHEAD STORAGE BINS ON THE OPPOSITE SIDE TO MY AISLE WHERE I WAS SEATED WERE NOT FILLED AND THERE WERE SEVERAL SUCH BINS ON MY SIDE OF THE AISLE (I DID NOT HAVE TIME TO COUNT THEM BEFORE I SAT DOWN). I ASKED AN ATTENDANT WHY THIS WAS SO GIVEN WE WERE TOLD THE BINS WERE FILLED JUST AS WE BOARDING FROM THE DEPARTURE AREA. SHE WAS POLITE AND SAID SHE WASN'T SURE ABOUT WHO MADE THE ANNOUNCEMENT IN THE TERMINAL BUT THAT IN ANY EVENT MY CARRY ON WOULD ARRIVE SAFE AND SOUND IN VANCOUVER - IT DID BUT WITH MY BOOK FOOD SNACK WHICH i HAD INTENDED TO USE WHILE ON MY WAY TO CHI. AND VAN."

Pros: "First time first class flyer. It was great!"
Cons: "Being separated from my wife in seating when we booked before others that we talked to!"

Pros: "The flight attendants. Especially Meagan and Heather. Amber was a,sweetheart too. I had the same attendants 3 out of 4 of my flights that weekend. So cool. When they realized it was me again they spoiled me rotten. So good I feel like unless I have those 3 as my attendants I won't fly United again"
Cons: "No food options. No free food"

Cons: "Really awful, disorganized and unapologetic."

Pros: "Got through sucurity ar PNR barely in time to make flight."
Cons: "Even though I am a frequent flyer with a Global Access card, I was select for enhanced security check. I paid for the Global Accessmcard especially sofas to avoid this. United said it was a TSA thing while TSA said it was at the prerogative of the airline. Why did this happen? So much for TSA Pre or Global Access."

Pros: "Like the free snacks while we waited 2 hours to board."
Cons: "Did not like waiting 2 hours to board."

Pros: "Usual United Corp mentality Overbook flites change your itinary leave you stranded with no connection spend nite in airport"
Cons: "See above"

Pros: "Flight was ahead of schedule to land and there was no issues of gates or disembarking"
Cons: "The food was terrible and the crew was bordering on civil there was no pleasantness about the services they provided"

Pros: "The flight was ok."
Cons: "It took a long time to hook up to the jetway once we taxied in to EWR. Pilot even commented that he didn't know what the heck she was doing out there."

Pros: "Seats were comfortable and sufficient leg room. One star rating on food and entertainment should be n/a since I didn't use these services."
Cons: "Boarding area was too small for gates being serviced."

Pros: "Flight did not happen"

Pros: "I liked when Delta stepped up and had us booked on one of their flights within seconds, after United abandoned us at their own terminal."
Cons: "Flight delayed 3 times due to maintenance, total of 5 hours. After final arrival time came and went with no plane or even announcement, I had to go back through security to front desk to find a rep and remind United that they had forgotten about us. They handed us off to the Delta counter with no apology (except the "new girl" apologized)"

Pros: "Not a single thing!"
Cons: "Arrived late"

Cons: "Kayak did not provide me with confirming email for flight in either direction and I missed my first flight to LA from Portland This is the second time I was not contacted via email from Kayak on flight reservations"

Pros: "The crew was nice and the area was clean."
Cons: "I didn't like the fact that before boarding they offered to check peoples bags for free because so many people were trying to take ridiculous sized bags onto the plane. I always pay to check my bag . That process took for ever but we did still arrive on time."

Pros: "nothing"
Cons: "it took me three days to get home. the first plane had a mechanical error. the second flight united booked me on was over booked so i didnt get a seat. the third flight they tried to send me on was also over booked. luckily someone volunteered to give up their seat."

Pros: "We stood in line forever to then be told the clerk couldn't ch we ck us in. When we tried the kiosk it didn’t work. Long story short we missed our flight due to their poor organization of the line and crowd."
Cons: "The confusion caused by lack of direction from the staff."

Cons: "Seating next to the bathroom is gross"

Pros: "Friendly and polite! Crew."
Cons: "Middle seat. Space too small."

Cons: "The flight was late. Emergency isle decent space"

Pros: "Couldn't really figure out your Wi-Fi system so I just read a book"
Cons: "It's not really easy to set up your Wi-Fi system through the United app"

Pros: "I had long waiting time for my flight from ORD and asked at stall if i can get early flight and the person at desk checked the system and get me early flight with no charge in cooperative and helpful manner with smiley gesture ."

Pros: "It use to be, I could put up with the lack of comfort and services because the cost savings made it bearable. But thes days, the basic ticket costs are high and increasing despite ala Carter pricing. The flights are always full and the number of flights are down. Airline profits are at a peak yet very little is flowing back to improve the flying experience."

Cons: "No agent to check in when I arrived at airport. Only at gate. No advance check in or advance seating. Allowed passengers to have more than 2 bags. Flight was late. No help getting to next gate or holding aircraft. Absolutely uncomfortable sitting."

Pros: "That I got a refund, although that should be a given"
Cons: "Had to purchase new flight day of, as I was told of flight cancellation 5 hours before leaving to the airport. I then had to spend $500 on a new flight, and one of the connections refused to let me on the plane. Stil not home."

Pros: "Pleasant crew"

Pros: "made good time."
Cons: "they lost our luggage on the way back,Didn't make it to Portland. But it was brought to our house at 7:45. I think for 1600.00 for tickets you should provide pretzels. That would be great. Thanks"

Cons: "Canceled flight, booked me an impossible connection, put on stayby when I get the tickets months in advance. Offered no vouchers and made me fly out on a diffrent day. Hs aircraft delays on all flights"

Pros: "Nothing."
Cons: "Never flying United again. On my way to the airport in Portland I got a text from United that my flight to Newark had been cancelled and there was no way to fly me out of Portland to San Diego that day. My sister had to drive me to Boston so I could catch a flight to San Francisco, which took 6.5 hours because it flew over most of Canada for some reason AND had three babies that cried from start to finish. Oh and because I was a late addition, I had a middle seat. The second I turned my phone on after we landed I had another yet another text from United saying that my connection to San Diego had been delayed three hours and wouldn't take off until 11:15 pm."

Cons: "Tried to get assistance at the United desk where my gate was located at and they could not answer any of my questions and would not assist me or many others who had the same issues."

Pros: "Nothing"
Cons: "Payed to upgrade seat was not comfortable and person next to me kept moving onto my side. Flight was 2 hours late so I missed my connection and had a terrible time to find a flight home. United staff was not helpful and kept telling me to go somewhere else for help. No food was served only tiny packet of way too spicy pretzels. Sat on the runway for an hour. Flight crew said 15 min and it was much longer. Crew seemed to be really confused."

Pros: "The flight was mostly on time (only 20 minutes late)"
Cons: "- Personal entertainment on United is false advertising -- unacceptable for a 10+ hour international flight. Namely, even if one happens to carry an appropriate personal device, the system was near impossible to connect to (none in our row were able to connect with a variety of smartphone, tablet, and laptop devices until most of the plane went to sleep. When we did connect, the streaming was so choppy it was nearly unwatchable. Then if you didn't run out of battery (plugs were not reachable under other passengers), the wifi went down completely for the rest of the flight). - Boarding was confusing (need to get a TSA sticker wasn't clearly communicated, nor when or how to get one). - Most flight attendants were rude to most passengers (not a personal experience, just an observation). - Economy seats felt half the size of those on the Lufthansa operated inbound flight"

Pros: "Polite staff"

Pros: "The crew communicated well to the passengers."
Cons: "I didn't get to Chicago until close to midnight, the flight to MSP was cancelled, and I missed my meeting the next morning. I understand you can't control the weather, but that didn't change the outcome for me."
