Pros: "Friendly crew"
Pros: "Good Flight"
Cons: "The check process was ridiculous. There not enough room in the box for me to explain my experience but the ticket agent lied to me, said he couldn't take my bag until I got a paper receipt and boarding pass from a kiosk despite having had pre-paid for my bag and digital boarding pass. 25 mins wasted"
Pros: "The crew was great. Honestly, they remembered my face and greeted me when I saw them that night in the hotel."
Cons: "I can't think of anything. I had great service on the ground and in the air. All the personnel were kind and helpful."
Pros: "The crew was amazing! The seat was comfortable."
Cons: "Used the self check in kiosk to begin! That was awesome! But after that I still had to stand in line to check in my bags. That part of the process took a bit longer than expected."
Pros: "Nothing special"
Cons: "That was the most uncomfortable and cramped seat I had ever had on a plane flight. Even sitting on the pillow did not help."
Pros: "This had one of the best attendants I have encountered. She was extra friendly and made us feel good."
Pros: "The A/C worked, that's about all"
Cons: "Old plane, no entertainment in head rests, had to use iPad not the same movies to choose from. Seats were so uncomfortable."

Pros: "Everything was on time and efficient. I also liked that the captain came on and updated us on arrival, turbulence, weather, etc."
Pros: "Snacks, drink, and spacious leg room in emergency exit row. Friendly and helpful crew."
Cons: "No entertainment"
Cons: "Flight was delayed out of St. Louis causing several of us to miss our connecting flight from Salt Lake City to Portland. Delta was of very little help in assisting us in making a connecting flight. They could have at least helped with travel arrangements and provided us with a little food, a pillow and a blanket as we waited in their terminal for the next flight on their airline which was a several hour wait. I understand these things happen but the passengers didn't cause the problem and Delta needs to take care of people better if they expect to earn repeat business."
Pros: "Cornell and Dorothy and the other flight attendants were the BEST! Cornell actually welcomed each passenger as they came onboard. Dorothy modeled the emergency info in such a graceful way... that you chose to pay attention because she made you feel secure. My colleagues and I have all agreed to fly Delta again ( specifically the Atlanta/ Milwaukee flight) Because of these courteous, caring, and professional people!"
Pros: "Nice crew, no delays"
Cons: "Stood by as people blocked aisle during boarding, making snide comments. Instead, the two should have assisted & encouraged the passengers to step out of the aisle & move along. Was very cold hit call light fir blanket. No response for 10 min so went to the bs k of plane where the crew was chatting & eating. When I asked about blanket, they didn’t look fir any & said they didn’t have any unopened. Upon leaving big plane, I saw a stack of about 5 packaged blankets in the front. Just rude & lazy older crew. Time for a different job fir them"
Cons: "Ac not working at last 30 minutes of flight."
Cons: "We lost our whole vacation and had to pay for the plans fare twice because My last name was spelled wrong on our tickets and we were unable to use them because my passport didn’t match the name on the ticket. We had to rebook everything pay almost twice as much for the plane fare, our Lodi g cost more and our trip was delayed for two weeks. Vyama is blaming us for spelling our name wrong and claimes that it’s our fault this happened because everything is automated. There saying they don’t touch anything that we enter into the booking but somehow everything they claim we entered is now in all capital letters and the space between our first name and middle name is now gone and all run together. The coustomer service number gets you to someone in India. I have tried to get this addressed four times now at first they tried to place the responsibility on the airlines now us and they have hung up on me twice. Kayak has been worthless, they also just pass the responsibility on to someone else. We will never use them again ant I intend to make sure that this mess is put out in social media to hopefully keep others from having their travel plans ruined by their flawed system."

This was at supper time; we wanted to eat in the terminal but were rousted from two different lines to change gates. We couldn't stop running back and forth long enough to eat! I got updated info more quickly from Kayak than from United, despite having signed up for email and text notifications and having the United app. Come on!! Eventually we were marched down to a narrow hallway, crowded with passengers from two other departing flights, held in formation by obviously harried gate agents and finally led outside to the ramp to board the plane. The worst boarding experience. Ever. Give me Southwest anytime."
Pros: "Very good no complaint at all"
Pros: "The crew made the best out of it and thankfully it’s an extremely short flight."

After spending a fair amount of time on the phone with customer service I was able to get me on a Flight to Minneapolis that did not arrive till 1:30am then had to take a rental car to drive 3.5 hours to make it to my destination. I was not compensated for any of this. My return flight from Fargo to St. Louis was also Delayed. Both from Fargo and from Chicago. I have never experienced such poor scheduling from an airline or as many delays or cancelled flights in just a few day period."

Gouging people leaving a massive flood! The governor of MO declared a State of Emergency yet my trip cancellation insurance didn't cover what was clearly beyond my control. I'm left with some hard feelings."

Cons: "No meal on business, no free internet, no entertainment"
Pros: "I made it home"

Cons: "My flight was delayed by an hour and a half. That's the amount of time I could have spent to drive home to Milwaukee. I stuck around because there was no indication of a flight cancellation. I would rather hop on a 15-30min flight than go through the hassle of renting a car. BUT the flight did get canceled, the next flight was completely booked and the next flight out after that was at NIGHT. I arrived in Chicago in the morning. The gate agent told us all to head to United customer service. There I received RUDE, poor excuse of a "service" only to be told they don't give refunds at the counter as we were told by the gate agent. So do that on your own time. THEN I had to buy my bus ticket and spend 1.5-2hrs on top of already waiting 1.5hrs for the flight that got canceled. HORRIBLE. Will never fly United again. Did i mention upon my arrival home I found out American was WIDE open seat wise to chicago?? And no one checked for me!"
