Scores according to KAYAK customer reviews
Pros: "New plane"
Pros: "Flight attendant was good"
Cons: "Everything else needed improvement"
Cons: "The flight was delayed, the first most important part is to depart on time keeping in mind the customers schedule as well that are travelling with the airline. No communication between the airline and ground department, was not happy at all and probably not fly unites again. Also they charge bags?"
Cons: "Delayed by 15mins"
Cons: "The seats are incredibly cramped. Also, they want $10 for 4.5 oz of cheese and crackers. Rip off."
Pros: "Arrived a little early!"
Cons: "7/8 size Brazilian airplane."
Pros: "The breakfast on the international flight was pretty good. However, there were more frequent snacks and healthier options when I flew internationally on Delta."
Cons: "I didn’t like that my pre-flight request for gluten-free snacks/meals was ignored. I didn’t like the attitude of one flight attendant who couldn’t bring herself to empathize with my allergy to gluten— which causes painful cracks in my palms and fingers."
Pros: "Received a text that the flight from Denver to Frankfurt is delayed 2 hours."
Cons: "Delay notification message did suggest calling the airlines to make change nor stating that I'll miss my connection in Frankfurt. I assumed I'll be missing it so I called Lufthansa to make changes. Their attempts to help took too much time, they did not look tat the trip from origination to provide best alternatives until I arrived to airport in Las Vegas to find out that again they had to change the booking and issue a new ticket. This took more than two hours. Had I not was preemptive I would have been stuck in Frankfort for an extra day."
Pros: "Same as above. Nothing to add"
Cons: "Late to board. Slow to run through safety. Late late late"
Pros: "Everything ran on time and the staff was very friendly."
Pros: "Although there was a slight delay, the flight was pleasant and the service very nice. We got twice something to drink and a snack. For the short flight, quite remarkable."

Pros: "no delays"
Pros: "The Crew attention was nice and very proffessional. Good coffee"
Cons: "We are very tired and the airplain isn't comfortable."
Pros: "How smooth and fast everything was"
Cons: "Being wedged in the middle seat after two overseas flights and seeing stand-by passengers in isle and window seats in rows ahead of mine... no, I did not appreciate that. In other words, UA is accomodating stand-by passengers before accomodating customers who have purchased tickets. Try sitting in a middle seat after two overseas flights... especially as a tall person with no knee space and a super-uncomfortable seat with the headcushion area reaching only your neck. Those seats were clearly made for folks under 5'8"-5'9"."
