Pros: "The crew was nice"

Pros: "Nothing, the flight was canceled without a refund. I highly recommend canceling all business with kiwi in the future."
Cons: "My flight could have occurred or I could have been refunded."

Pros: "Being on time with everything."
Cons: "Nothing"

Cons: "3 1/2 hr delay"

Cons: "Really felt happy on time touch down nice journey with delta"

Pros: "The crew was awesome! The steward was engaging and made us all laugh and feel comfortable for a short flight when he didn’t have to. He had a great sense of humor and gave the kids cookies and wings. Something I haven’t seen in many years. He and the pilots were great!"
Cons: "Nothing."

Pros: "Friendly crew"

Cons: "During this trip all my flights got delayed and I was told that I could not get a hotel room and had to pay for myself."

Pros: "On this short flight, the flight attendant was wonderful, accommodating special requests and being fully engaged with passengers. On time departure, early arrival, overall a nice quick flight to Duluth."
Cons: "CRJ200 planes are always a bit cramped, and having to gate check anything bigger than a small purse is an inconvenience. Hopefully the fleet will change over to the Embrair planes soon. Beware 'Basic' flyers (cheap tickets): you are not eligible to take an earlier flight even if available."

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: "I like that I arrived at my destination safely."
Cons: "My allergies were bothering me due to the airlines allowing animals to travel as passengers, in this case a rabbit. I am very allergic to animals. My breathing was compromised."

Pros: "This had one of the best attendants I have encountered. She was extra friendly and made us feel good."

Cons: "The flight was 2 hours delayed.. this cause a lot of inconvienece.."

Pros: "Informative communications during delay"
Cons: "Rushing to board resulting in bad customer service during boarding"

Cons: "Food was ok...cramped space"

Pros: "It is good to be able to go straight to Paris without connecting."
Cons: "Boarding was a bit slow."

Pros: "Everything was on time and efficient. I also liked that the captain came on and updated us on arrival, turbulence, weather, etc."

Cons: "poor hospitality by cabin crews cabin crews are very stingy in providing drinks"

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."

Cons: "Ac not working at last 30 minutes of flight."

Pros: "Nothing"
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."

Cons: "They changed my flight to a different one departing 2 hours earlier and did not notify me! The original flight was still available & they would not let me take it despite my reservation paper work. CRAZY! I have a two hour drive to the airport this gave me the option to leave home at 2:30am or go the night before and pay for a hotel. Flight was managed by DELTA who also did not care! All involved blamed each other. Beware"

Cons: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."

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.
