Pros: "It suited the time i could travel"
Cons: "I felt although they said the two attendants were great they were at best mediocre especially the man"
Pros: "Flight was mostly uneventful, which is great! Right after takeoff we made a complete circle and no information was given as to why, but we assumed it was air traffic."
Pros: "Everything! I appreciate that the ticketing agent helped me get an earlier flight and I appreciated the gate agent making sure I had a good seat! I love Delta!"
Cons: "Nothing honestly"
Pros: "Good flight as always with Delta. Sat in economy comfort, so of course the seats was comfortable. Flight Attendants were great."
Cons: "I checked two bags and paid for them. The flight was full. I dutifully got in line for zone two. Next thing you know, at least 25 people got to board early and have free bag check. Really? I should get $35 dollar refund."
Cons: "The flight was 2.5 hours late making me miss my connecting flight and I didn’t receive a refund for the comfort seats I paid for but didn’t get."

Cons: "My friend and I was switched to an even worse seating when boarding. Very uncomfortable especially for my friend since he had crutches."
Pros: "The flight back to Columbus made up for the flight from CLT to SJC."
Cons: "This was a multi city, round trip starting out of CLT. My connection was way too close, and we missed the connection due to a mechanical problem. The lines to get vouchers were super long, and the hotel was not the best. It was way after midnight when I got to the hotel, and I did not feel safe staying at a Quality Inn. I had to walk to my room outside, and had leave in the morning in the dark as well. I was traveling alone. Please put your passengers in a better hotel, closer to the airport. I did not expect that from American Airlines."
Pros: "Leg room"
Cons: "Plane was late for takeoff and we arrived 30 minutes after scheduled time. They didn’t announce a delay or apologize."

Pros: "Everything seemed to go as normal. We were able to get 5 seats together."

Pros: "Very smooth fligh and very friendly and helpful staff"
Cons: "The seats were extremely crammed and there were no movies or shows without purchase"
Cons: "My seat had garbage on the seat, on the floor and in the front pocket"
Pros: "Overall the flight process was fine."
Cons: "Kayak is not transparent enough about highlighting which flights are low cost flights during purchasing. I thought I was purchasing a regular fare where I could bring a normal carry-on onto the flight, but this was a low cost flight and I had to check my bag. This information was not disclosed until after payment, and I believe this is dishonest on the part of Kayak. Kayak needs to be much more upfront about the details of the flights so that we passengers can select flights according to their needs. I felt deceived by the fare and would have purchased a different flight if I would have known ahead of time."
Pros: "Nothing"
Cons: "I was very I'll and could not complete this flight. Was told by airline to call Kayak for changing date of flight for $50 vs $200 they would charge. Ticket was less than $200. I called Kayak. They said sorry it will cost you $200 per airline policy. Either way, this is unacceptable to me. I will stick with Southwest who let's you change flights on all fares if you use it within one year. So since change fee was more than ticket I just ate the cost. Not happy with UNITED or KAYAK. Won't use either one again."
Pros: "All fights.. On time made it home safely Friendly crew both ways.."
Cons: "Entertainment should be easier to access.. And Free!!"
Pros: "Nothing"
Cons: "The landing was horrible. A lot of passengers were upset."
Cons: "No food provided (unless paid) and no entertained for 5 hr flight, if you didn't have a device."
Cons: "This flight was delayed for 1.5 hours which was not nice and it was a six hour flight and only could receive pretzels without paying for food."
Cons: "I will never fly with them again, you have to pay extra for everything, even carry on items, seats sucked."
Pros: "It was ok, male flifht attendant super friendly"
Cons: "The seats weren't that comfortable for my husband due to his height."
Pros: "I liked the crew and stewards. All very nice and helpful. The flight was pretty smooth and nice touch down. Not too bumpy."
Cons: "I ordered a water and the steward forgot and I had to remind him. The seats are a bit cramped and there is no entertainment options to speak of. There should be WiFi in this modern age."
Cons: "I didn't like having to pay my bag twice. My flight was delayed 2 hours causing me many issues upon my arrival."
Pros: "Nothing"
Cons: "Door being closed when I was about to get inside. I won’t be boarding spirit again!"
Cons: "Charge for a seat, baggage including carry-on and a bag of pretzels is 4 dollars. Don’t fall for the cheap tickets"
Pros: "The price!"
Cons: "The seats are quite small, and the seats do not recline at all. So little leg room for those that are tall, like my husband."
Cons: "Everything was really bad. I will recommend everybody to run very far away from this company"
Cons: "Dirty Seat doesn’t recline Seat doesn’t have head support on sides No movies No phone charger Small food tray Poor food choice No free water"
