Pros: "Crew was excellent, boarding process was orderly and clearly explained."
Cons: "Seat too narrow."
Cons: "Really old plane. Not well cleaned. Bring sanitary wipes for seat and tray tables. But cabin crew is top notch."
Pros: "The crew was excellent and boarding was a cinch. I volunteered to check in my girlfriend and I's bags and the process was very easy."
Cons: "Compared to other airlines, I think their food and beverage service was a little lacking."
Cons: "The pkane changed departure times, so i was stuck in airport until 440 pm and i had to pay $60, to change ticket."
Pros: "They allowed passengers with little children Board first, unlike the trip from LAX to Boston we had to wait until our class even we traveled with 3 little children"
Cons: "Let passengers with special needs board first, and announce baggage claim carousel number before entering the gate"
Cons: "If we were able to get some real food and real answers when our flight was delayed for 5 hours. We got pretzels and cookies and that was it even though all the resteraunts in the airport had closed so we had no other options! We also kept getting told the fix would happen soon and it took 5 hours."
Pros: "Plane was new, boarding was easy and on-time"
Cons: "Passenger seated beside me was morbidly obese and spilling over into my seat........"
Cons: "Bathrooms were not maintained during duration of flight. With airlines like Delta and JetBlue stepping up their in-flight service Alaska needs to get with the program. I think everyone and their mothers we're in boarding group C but yet no one was in A...make it more dispersed."
Pros: "Nothing"
Cons: "Alaska airlines is a consistent let down. This was the LAST time I will ever fly them. A 9 hour delay because their captain called out 1 hour before the flight. They did NOTHING to compensate the entire plane, made ppl leave back into a city with their bags, no food, etc. The gate agents handling it could've cared less and told people to call and complain it wasnt their problem. The service was horrible from top to bottom and cost people their entire day. Many missedevents, connecting flights and Alaska all the while didnt even comp a coffee to people theyd stranded from 6am to 6pm ,"
Pros: "Movies"
Cons: "lack of Cleanliness, one crew member was rude and pushy (not to me but in her tone and to others),"
Cons: "Nothing... great flight, uncrowded flight, plenty of extra seats to stretch out. Seat were very comfy and spacious which I loved even got a full can of soda unlike the usual half a cup and done lol. Would definitely fly Jet Blue again and prefer also. Way better than the other carriers."
Pros: "Crew was excellent. Boarding was great."
Cons: "I had significant delays on both the flight to Logan & the flight back to Charlotte."
Pros: "crew was great."
Cons: "flight was 3 hours late with lame excuse. tray tables disgusting. felt unclean. cookies tasted gross. pa system not working. live flight not working either"
Pros: "Crew was nice and accommodating. Plenty of leg room in regular cabin. Good entertainment options.?"
Cons: "We waited in the runway for 2 hours after landing. Not the airlines fault however completely unacceptable."
Pros: "Everyone was boarded early so we departed early. Quick flight with pleasant flight attendants and nice snacks."
Cons: "The desk agent in Boston could be a little more pleasant."
Pros: "Crew was nice. legroom seemed a little better than other domestic flights."
Cons: "You have to pay extra to sit in the exit row and there was no one in the entire row. Isn’t that a safery issue? Also, what really made me mad, instead of printing our boarding passes at the kiosk we went to a person (husbend had questions about Precheck) and she made us buy return tickets right then, on JetBlue. We had not decided on our return and wanted to leave it open. Can she do that? If not, I would like my money back."
Pros: "Boarding was great and on-time. Flight took a bit longer due to the weather."
Cons: "Couldn't understand any of the in-flight announcements. My in-flight entertainment didn't work right."
Pros: "Seats are very comfortable"
Cons: "The flight is so much delayed. The flight attendent seemed not happy about me with a two year old, which makes traveling with a kid so unpleasant. When my kid asked to go to restroom, it seemed that we’re troulesome. My mom missed the water when they gave out drinks, but they did not come back for us. When I went to the back to ask for my mom, they said they’re cleaning up already."
Pros: "Friendly staff and a smooth takeoff and landing. All I could ask for. This was the 1st time that I flew JetBlue and I was impressed."
Cons: "The middle seat but that was probably my fault."
Pros: "The crew was great. The pilots too."

Cons: "Delayed boarding"
Pros: "Crew was amazing. Pilots were attentive to kids and answered questions. Everyone was very welcoming and helpful."
Cons: "They didn't have some of their food options (and they apologized for that up front), but then ran out of the others by the time they got half way through the plane. That was tough for a five hour flight that went through dinner time."
Pros: "Nothing"
Cons: "Better customer service. Your employees should be te-trained and reminded they are in a service industry where your clients have other options to fly."
Pros: "Seat was hard, not much foot space"
Cons: "My wife and Iasked for a snack, it was never delivered"
Pros: "Good entertainment options."

Cons: "The crew members were very rude and they called me an IDIOT!! Yes they did because the forced me to check my carry on bag and i didnt want they are racists"
Pros: "Crew was friendly"
Cons: "An hour and a half late, terrible communication about scheduling"
Pros: "Great service"
Cons: "Look, if your kid is so young that he can’t get in a plane without screaming for four hours, you shouldn’t bring him on a plane and subject 200 people to that. It’s rude and selfish."
Pros: "Crew was nice. Boarding and deplaning was quick. Flight was on time"
Cons: "WiFi was super slow"
Cons: "The gate attendant was very hard to understand and so I couldn’t hear what she was saying."

Pros: "Good pilot/ crew to passenger interection. Great movie and entertainment selections."
Cons: "Turbulence but airline / pilot can't control that."
Pros: "Crew was nice and kept us updated."
Cons: "Flight arrived 20 minutes early and we still deboarded 20 minutes LATE. Wifi on flight is ten dollars instead of being free and they use plastic cups for the drinks which I am sure is not recycled."
Pros: "Smooth flight, not too bumpy. Also flew on time and landed early. Free beer"
Cons: "No internet. No tv screens. Jet blue is still better."
Pros: "The flight to Washington was fine. It was the flight back that I have issues with."
Cons: "My issue with flying back American is that...I didn't. They boarded us on the plane, moved down the tarmac, and then checked to see that we had a brake problem. They took our plane out of service (which I get, I would want brakes before takeoff), but then they never updated us on our status, until I physically went to the counter to ask an hour later. This is when they informed me that the flight was cancelled and we were rebooked on the 9pm flight (Mind you, this is 12:30p and I have a 2 year old with me). Luckily, I was able to book JetBlue and get home earlier (8:00pm)"
Pros: "We had to wait in the airplane upon arrival in La Guardia NY because wheelchair was not ready."
Pros: "Everything great. Rate food and entertainment moderate because there was no dinner, which we did not require, and we went to sleep so didn't pay attention to entertainment."
Pros: "Great crew made the trip pleasant."
Cons: "Aircraft had no WiFi, broken tray table and was pretty worn."
Pros: "The staff at the boarding gate and the flight crew were friendly and professional."
Cons: "The United gates at Logan airport were quite horrible. Poor signage, limited bathrooms, and all the dining options were quite expensive."
Pros: "I liked the ticket price."
Cons: "The seat was very narrow with absolutely minimal leg space, and a carry-on bag was not included in the fare."
Pros: "Salmon and rice."
Cons: "Tvs not working and staff pretending as if they would fix it but actually the problem been going for a while with that airplane. The pizza should not only be a vegetarian one ."
Pros: "Non stop . Wife and I were given side by side seats"
Cons: "Last row"
Pros: "The crew from the ticket agents all the way up were great. The app for iPhone is great."
Cons: "I paid for 30 minutes of WiFi to download the United app on my iPad. I wanted to watch the movies/tv shows that were available to passengers. The WiFi was spotty and slow so I wasn’t able to load the app. Needless to say I was disappointed. I also was disappointed with the seating. I am an average size person and I felt very cramped in my seat. My shoulders and neck are killing me after a 2 hour flight. I know that I chose the economy seating but I don’t remember the seats being quite so narrow or the leg room being non existent."
Pros: "A very tall, male, flight attendant very wonderfully took me almost all the way from one end of the horseshoe to the other. I didn't catch his name but he was SO helpful."
Cons: "My flight was delayed by a few minutes and by the time we got to San Francisco, boarding was almost done for my connecting flight. I had to literally run from one end of the United terminals to the other... the entire horse shoe."
Pros: "Everything ran on time and the staff was very friendly."
Cons: "I was there on time but was told my travel information was not on found even though I had the email confirmation and I lost all the money I paid."
Pros: "I liked the comfort that the plane gave. I also enjoyed the fact that the crew was all very friendly and kind."
Cons: "There was no music or free tv to watch on flight. There were delays due to high traffic."
