Pros: "Flight crew was nice"
Cons: "They were careless with our suitcases. When we got to Vancouver, we were missing wheels on our suitcases. 2 wheels on my husband's and 1 on mine. It made it horrible to pull the suitcases."
Pros: "Crew was great, the flight was good. Food is good but expensive."
Cons: "Free or inexpensive food options would be nice. I also prefer when the screens are in the back of the seat and I don't have to stream on my phone or pay high prices to use data."
Pros: "Crew was friendly"
Cons: "Tray tables very dirty, flight overbooked, hard to find gate agents"
Pros: "The flight was great and the process from boarding to take off was wonderful. This was also a rescheduled flight after my other flight was cancelled."
Cons: "The seats cushions. They weren't the best. That's all."
Pros: "The flight attendants on all three of my flights were nice and helpful as well as all the employees at each airport I visited. The food was good and I had a great time."
Pros: "My bags were about 3 pounds heavier than allowed and she let me in with them. The crew is overall very nice and professional."
Pros: "Flight was on time despite a late arriving flight attendant and a slow taxi after landing"
Cons: "Flight was crowded, several screaming children were very annoying, and the cramped seats meant that I was constantly getting jostled by people going up and down the aisle even though I was fully inside on my seat and pressed up against the passenger in the next seat."
Pros: "It got me to where I was going. Attendants were very good."
Cons: "Long flight delay. Seats were cramped."
Cons: "My connecting flight was late and they gave my seat away. So I’m not on the flight. Worst of all I was made to feel like it was my fault for being late"

Cons: "We weren't alerted there was a chance of delays. Over two hours late."
Pros: "Great seat easy flight. The food always seem to be the same. I wish they would change it up every once in a while. I've been on this flight 14 times this year and its always exactly the same.."
Cons: "The gate was under construction in Seattle, and it was impossible to hear the gate agents."
Pros: "Crew was very friendly and efficient. Flight was pretty smooth."
Cons: "On time departure would have been nice. 2.5 hours late."
Pros: "Use my built up miles for the SEA-ANC leg of our trip, as to physically price it out as one ticket usually increases the fare by 300-600 u$d depending upon time of year. As it was the tail end of an already long journey (OKA-ICN/ICN-SEA), booked the First Class Cabin. Every mile was worth it."
Cons: "N/A"
Pros: "The crew really kept us updated on the many delays."
Cons: "There were SO many delays and they kept changing. At one point we got on and off the plane."
Cons: "We paid for comfort plus but the seats were no different than main cabin. Comfort plus experience on other legs was much better."
Pros: "Super friendly staf, big enough seat, good enough food, enough room for luggage."
Cons: "Seat was smaller than EVA and food not quite as good."
Pros: "The food and the crew totally good"
Cons: "Maybe the toilets, need to be clean at least once in a flight"
Pros: "Crew was super nice"
Cons: "Airline to be more user friendly with connecting to free entertainment"
Pros: "Crew was efficient and pleasant making for a good experience."
Cons: "Nothing"
Pros: "The flight got me there"
Cons: "WiFi was too slow to be able to watch anything. Seat small and uncomfortable. Flight attendants not friendly."
Cons: "Boarding could be improved if they would start boarding from the back of the plane to the front after boarding 1st class and Priority this way people would not block the passage when putting their luggage in the top compartments. The crew was not very helpful because I almost went into a hypothermia condition because the air in the cabin was extremely cold. When I ask for a blanket one of the stewardesses said that AA would no longer have blankets in flight which I prove it wrong when I saw in the flight Mai-SDQ blanquets all over the cabin. The soliton they gave me was that they would ask the crew to raise the temp in the cabin, I had to make the request three times and I had to tell the stewardess that if not raising the temperature in the cabin I could have gone into an emergency hypothermia crisis. I had to take another shirt from my carry-on to put it over my shirt to warm me up."
Cons: "Instead of flying MIA-EWR I was sent to ORD and then to EWR arriving at 11:00pm"
Cons: "Flight was delayed for whatever reason. Did not give us a reason why. Also boarding was very haphazard. They just boarded all groups at once to try to make up some time. Almost did not make it to our connecting flight in time"
Cons: "Not enough time in London to change planes. We missed the flight"
Pros: "For this flight I was seated in first class (I scheduled it this way; it wasn't due to a last minute upgrade) and the flight attendant was very personable and attentive :-) Service was wonderful and the meal was great! Of course, the flight attendant made sure to keep our beverages topped off as needed. It was a wonderful experience"
Cons: "The boarding process for just about any airline is nearly identical. It always seems like it takes longer to board than expected even if, in reality, it's not an unreasonable amount of time. The only think I didn't care for was that overhead storage in the area I was sitting was just about full by the time I was seated which meant that I had to store my carry on a few rows behind where I sat. This meant that during off-boarding I needed to go against the flow of people to get back to my carry on. All in all, it was a minor inconvenience."
Pros: "Our pilot was great. Kept us informed, was pleasant and got us in early. I appreciated the extra information he provided regarding expected turbulance and arrival updates."
Cons: "There wasn't individual entertainment unless i used my own device."
Cons: "ran out of the food i wanted. poor selection of food... screen on "tv" was too dark to see details"
Pros: "Nice, normal flight."
Cons: "Pilots not there on time, arrived perhaps 30 minutes late, didn’t say why."
Pros: "No complaints about the flight or the crew."
Cons: "Delayed repeatedly. 3 hours behind schedule and no clear explanation was offered."
Cons: "Almost a 5 hr flight and there was no food or snacks given and water by request only. It was a full flight and the crew had just an attitude. Never had a flight like this one before. Horrible just horrible"
Pros: "Not a whole lot."
Cons: "Everything. The flight was delayed by 4 hours. There was no food in first class. The luggage was put on an earlier flight ans delivered to a different gate. The person handling luggage in Gate A was rude. We had to go to the other gate at 1am to pickup our luggage."
Pros: "Got home without delays. As satisfactory as possible in economy class."
Cons: "Much better flight back than going to switzerland"
Pros: "I called to change my flight to an earlier time due to flooding in PA. The lady who helped me did an equal exchange for my ticket and waved the $200 fee. I was extremely pleased and appreciative. Also, excellent movie choices and food options. I will definitely continue flying with United."
Pros: "The flight was smooth and on time Liked the window seat Staff friendly and courteous"
Cons: "Legroom is uncomfortable. I'm 5'11 and it is tight, and there is barely any recline anymore No power in the seats - there is a Wifi entertainment option (good) for you to use your own device, though need to run on battery Security checks took more than 1h, almost making me miss boarding There are enough drawbacks/compromises regarding customer service that I will alternatives where they exist"
Pros: "I liked the movie screen showing me where we were and how much longer it would take to get to the destination. The flight was super smooth."
Cons: "No decaf on an overnight flight. No cookie, only a tiny package of pretzels. Cheapskates."
Pros: "Stewardess was very kind and engaging, even in the middle of the night!"
Pros: "Seatt space was great."
Cons: "The seats didn't recline at all making it nearly impossible to sleep."
Cons: "Crew arrived late so left about 45 min late...but communication was good and timely and we arrived only 15 past scheduled time."
Cons: "Why a passenger get a ticket for $189 paying $50 for lagage need 2 or $3 to get a bottle of water? I didn't appreciate that from you guys we need to work on that. We don't ask for snacks. After that everything was fine. Good job to the team"
Cons: "Seats are very tight No space Will be my last trip on spirit"
Pros: "In-flight, no one (flight attendants) really bothers you."
Cons: "Communication amongst the airline and it's PAYING customers, TERRIBLE."
Pros: "I wish I would have been notified sooner for the 3 hr flight delay."
Cons: "The person next to me was as huge as I was."

Cons: "Nothing."
Cons: "we were given multiple notices, late---on time---late---finally when told the flight was on time, we went to the airport, only to wait 5 hours. spirit was not honest with us, and they did not compensate us t all, not even with a soft drink once on board"
Pros: "It was smooth and uneventful. At 6 AM that is saying a lot...!"
Cons: "n/a"
Pros: "Flight crew was nice enough, but the intercom woman was very annoying; spoke like we were children. How many times do you need to announce a last bathroom call? 1 is diffident. 5 is excessive."
Cons: "Charge you for EVERYTHING. Seats were so small i couldn’t bend down to find my headphones in my bag on the ground. I’m 5’4” 115 lbs. no in flight WiFi or entertainment. It was a long flight."
