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: "Everything was on time and efficient. I also liked that the captain came on and updated us on arrival, turbulence, weather, etc."
Cons: "Ran out of snacks by the time they got to my row"
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: "It was short and fast."

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"
Pros: "The flight is short"

BA booked me on the flight but failed to change my ticket from the original flight causing me to miss the flight from Kansas City. At the airport BA agent told me on the phone that I would have to wait 3 more days after I had already waited 3 days because BA canceled my original flight. Because of the flight cancelation I missed two days of work and because of the failure to ticket my following flight I almost missed a full week of work.

Fortunately, the AA agent was able to find a way for me to continue my trip on a later flight."

Cons: "- The entertainment system was not working - needed few restarts - on many seats - Food - horrible - Air hostess dropped water on me - not a problem by itself as accidents do happen. However her comment was more annoying - no sorries - not apologies - just said - "oh it's just water - it is refreshing" - Seats pushback was almost broken - it would break your thumb to push the button and then almost stand to push the seat back. - This was transatlantic flight and you charge for liquor? It is not free - you have to purchase - They ran out of red wine (which was free) by the end of the first meal. Do you keep just one bottle for this big 777 fight. - Overall experience was horrible."
