Pros: "The lady who check me in was very sweet and took care of me. I give her 5 stars"

On time. Affordable seats for more space! Seats were uncomfortable. Too tight and I’m petite seated in the middle.

Pros: "Free on board WiFi and a very clean plan... JetBlue you are the best"
Pros: "Female attendant was personable. Decent legroom but tray was broken."
Cons: "Was told by attendant they’re NOT supposed to help female guests with urging luggage overhead. Didn’t know headphones had to be bought to watch movies."
Cons: "The seats were awful and uncomfortable. Payed 100 dollars extra for even more leg room and barely had any. Such an old plane for such a long flight. The seats in the first row barely fit a female with hips. The in-flight entertainment was staticky and you could barely see the TVs. Overall, one of the worst flights I have taken on JetBlue."
Pros: "Nice crew, nice plane"
Pros: "Complimentary snacks and drinks."
Cons: "Broken seat back, broken tray table, audio input didn't work."
Pros: "Crew was nice, and pilot was helpful and got us there early."
Cons: "My screen for movies didn’t work, and the level of comfort was... almost none. I would’ve upgraded to more room, but for $55? When I’m already checking a bag for $30? On top of flight price? Too high, expected JetBlue to not jam pack all the seats like the exit aisle.... for long flights, not again."
Cons: "Some flight attendant do not know how to treat people"
Cons: "Newer plane with less issues. Wasn’t comfortable at all and should be cleaner."
Cons: "Blue chips were not available! I really love them"
Pros: "Nothing"
Cons: "Plane to JFK cancelled. Jet Blue blocked ticket next day at 6am for China Southern. Spent additional $120 in transportation so I could leave home at 2am. Then when at JFK had to get a ticket at desk after an hour walking and being in line and after strong protest for they were not going to give me a"

Pros: "JetBlue's free Wi-Fi and comfortable seats really make JetBlue a domestic airliner unlike any other."
Pros: "Crew was friendly. Food was good, especially the beef at dinner"
Cons: "Breakfast omelette was rubbery and really not good. Layover was way too long (4h). Not looking forward to my 11h layover on the way back, but at least JFK is a nice airport and I have lounge access through one of my credit cards"
Pros: "Service"
Cons: "Seat cushions need to be replaced! Plane seats were not cleaned either"
Cons: "Jetblue the best"
Pros: "4 hours late. Many people missed connections. We were up over 24 hrs by the time we got home. Had to check out of hotel & sit at airport for 8 hrs. Rough trip home after great vacation. Head of flight crew was very rude, likely because she was so tired. Rest of crew was fine, though I'm sure equally tired. Plane very comfortable though."
Pros: "Staff"
Cons: "See above. Had to wait 30 minutes at JFK to open up"
Pros: "Everything was smooth, great service, friendly staff and captain. Arrived ahead of time. Free Wifi. Great inflight entertainment."
Pros: "You can always count on JetBlue for good snacks and free WiFi."
Cons: "But the snacks and free WiFi is not enough to payback the delayed departure experience. Just a week prior, my JetBlue flight was scheduled on time and then three things delayed thre flight for three hours right before we took off and now this! I was told it was due to needing to replace a crew member from another delayed flight. How can that affect so many people? The seat was also super uncomfortable and the back of the cushion was rolling forward, which made it hard to sit for that long. we also didn’t have a gate when we landed so that added on an extra 30minutes. Really disappointed."
Cons: "My family and I decided to travel with JetBlue instead of cayman air because they had the tv’s for the kids entertainment. Was very disappointed when they didn’t work the entire flight home"
Pros: "Nothing"
Cons: "Everything"
Pros: "The flight was very smooth and the staff was very nice."
Cons: "The wifi did not work at all and my TV did not work so I had to listen to my music the entire trip."
Cons: "The Black guy service is not good"
Pros: "Adequate leg room and ample seat size"
Pros: "I like the unlimited snack and beverage options, it definitely came in handy for a Red Eye flight. The crew was polite and accommodating and the plane was clean."
Cons: "I didn't like how cold the plane got at one point and that one would have to pay $5 for a blanket. The signal for the tv would be inconsistent throughout the flight and when it did work, the quality was pretty grainy."
Pros: "Nothing good to say"
Cons: "The whole team was rude not helpful at all all they did was give an attitude only nice person was the girl with the glasses the other 2 infront rude and not helpful at all"
Pros: "Flight came out almost at time, arrived in time any way. The luggage arrived quickly, it was the only night flight from LA to NYC that I could found in great price."
Cons: "Serious minus were the seats! Awful seats, back of the seat can’t be banded, very hard and uncomfy to sleep like this!"
Pros: "As always, JetBlue gives one of the best mobile experiences while traveling, excellent flight as always with everyone from the staff very attentive and nice. Good to still be welcomed during the flight to those popcorn chips! An excellent overall experience"
Pros: "That Harry Potter was playing"
Cons: "That our flight got delayed so many times, they changed the departure time to sooner at the last minute and we had to book it to the gate from security, we missed our connecting flight and had to sleep in the airport."
Pros: "Great take-off and landing"
Cons: "Turbulence"
Pros: "Non stop flight"
Cons: "Loudest airplane I've ever flown on! All though there is excellent leg room the seats were the most uncomfortable!!!!"
Pros: "Comfortable and cheap."
Cons: "N/A"
Cons: "The seat was worn out into a bowl and very uncomfortable. They also forced me to gate check my bag. Why not check for free if you are always forcing us to hate Check?"
Cons: "Baggage was lost and no one seemed to know where it went. But then it turned up in my hotel a few hours later so at least it got worked out."
Pros: "Service"
Cons: "That you can't turn off the movie"
Pros: "Crew was very hospitable"
Cons: "The headphone jack wasn’t working properly, sound was muffled and fuzzy. Couldn’t enjoy any entertainment provided. The flight was full so I couldn’t ask for another seat either."
Pros: "Free in-flight WiFi service for all travelers on the plane. Many onboard entertainment choices available using individual LCD screen display. Many selections of in-flight meals and beverages available for purchase during your flight. Online seat selection and online check-in were fast and efficient. Additional perks for travelers available online."
Cons: "There was no food included in my flight."
Pros: "On time. Liked not having to change terminals for connecting flight."
Cons: "At 5:30 am, Jetblue check in personnel in WPB were rude to passengers. Said It was our fault we were in wrong line to check our bags bc we had not read the sign that clearly said if we were pre-checked we should have waited 10 yards to the right. She refused to take our bags in the full sevice line until other passengers deferred and insisted our bags be checked In ahead of them since we had been waiting longer. There were not enough people to staff the bars in the JFK terminal before our flight boarded. Waited 15 minutes for one bartender to return from break. At next bar, in front of gate #16 there was no bartender. After 15 minutes someone appeared, only to take orders and disappear. Finally got a drink at a restaurant, nearby, but they said the drink had to be consumed there, not taken in the plane. No alcohol was offered on the plane between JFK and Burlington. Baggage crew ripped the handle off my Rimowan luggage."
Pros: "Seats were comfy."
Cons: "No coffee. Snacks were smashed."
Pros: "We were running a bit late for our flight, so the employee at the check-in counter made sure we checked in as soon as possible! He even checked in an extra bag free of charge, so we could go trough security faster! Greatly appreciated!"
Cons: "My in-flight entertainment system didn't work. Even though they offered me a voucher for the troubles, it made my flight a bit boring."
Pros: "I liked my face mask. overnight flight"
Cons: "I don't think there is the option to turn off the TV"
Pros: "Professional and genuine people who reflect the good in life."
Pros: "You can pretty much count on having a great crew with JetBlue This flight's embodied patience: patience with the lady who wanted to bring a smartecarte loaded with diaper bags, blankies, handbags and stuffed animals onto the plane; patience with the baby in the first row who cried throughout the entire boarding process and patience witht; patience with the lady in the first row (who didn't have a seat in front of her to put her handbag containing a small service dog underneath) and two, I guess, wanted to keep the dog on her lap during take off. It was a plane full of first time flyers, with resulting chaos. And they kept their cool throughout."
Cons: "It was a plane full of first-time flyers, with resulting chaos. it's not Jetblue's fault that people are chaotic and babies cry loudly when they are in unfamiliar surroundings. But it sure makes it trying for people who are sharing the same cramped space. You don't realize that there's an art to being a good passenger until you see passengers who are unskilled at being passengers. I know this sounds very unkind, but it was a late flight."
Pros: "The check in line was a little long, but moved quickly. Then the unthinkable happened and we got wind of our friend passing just as we got to the front. The woman working at the counter felt so bad for us that she actually moved us into our own row so that we could have the space to grieve. We were also traveling with a dog so that in itself was so kind and accommodating."
Pros: "Friendly crew, efficient."
Cons: "Check in with partner airline was super glitchy"
Cons: "Short flight great friendly service."
Pros: "layover time is short. Transfer gate is very convenient."
Pros: "Great service"
Pros: "Early departure early arrival"
Cons: "Food options, more prompt service,"
Pros: "PLane was clean, boarding went fast, meals and snacks were decent."
Cons: "The sound system was turned up too loud. Did not appreciate being bombarded with advertising on the entertainment system, on the Loud speakers as cabin crew hawked the company credit card etc"
Cons: "Honestly, this was my first time flying with Hawaiian Airlines and I was very impressed with the overall professionalism and how thorough the staff was in making sure everyone had their seatbelts on when necessary. They were also very kind and friendly."
Pros: "Crew Food Seats"
Cons: "More fruits & Hawaiian chocolates"
Cons: "Food, leg room!"
Pros: "Short island hop but still great staff is just HAPPY"
Cons: "Canceled flight, major next day flight detour!"
Pros: "Great service."
Cons: "Nothing"
Pros: "Crew was friendly."
Cons: "We were late leaving the gate in LA. Now we have been sitting on the plane for 45 minutes waiting for our gate in Honolulu."
Pros: "Comfort plus in the front cabin is nice and quiet"
Cons: "Entertainment screen had problems."
Pros: "The crew was very good and met all our needs."
Cons: "Free entertainment from LA to Honolulu."
Cons: "My surfboard bag was ripped and all straps were broken and was then patched up with duct tape!!! What the F#€*?!! It looked like it fell off the plane and was run over. Plus my bike box was torn to bits and patched with duct tape and was cut open by someone’s knife, I ended up loosing bike parts because of this. Horrible bag handling by the crew!! This was all noticed when I picked up my bags in Auckland"
Cons: "Racially profiled by security guard..Never coming here again."
Pros: "Fantastic attendants, clean, overal A+"
Pros: "The staff on the flight was great."
Cons: "Screaming babies everywhere."
Cons: "Most airlines offer free entertainment on long distance domestic flights as long as you bring your own headphones. This is a 5-hour flight. Why would Hawaiian Airline want to charge $7.99 for viewing a movie?"
Cons: "I received more updates on delay, gate changes and expected departure time from Kayak by text messages than from the airline. There were regular gate area updates. Passengers were not given any 'make-up' benefits for the 6-hour delay, like access to pay movies or discounted pay for snacks. I don't favor free booze. Even the meal was crappy, not that the crew could change loaded meals. Passengers felt like the delay was not big deal to the airline and crew."
Pros: "Flight staff was pleasant. Ticket agent at the gate got my mom and I a seat together closer up."
Cons: "Flight was delayed by 3 hours leaving Sacramento, I booked seats together for myself and my mom but when I checked in they had us across the plane from each other. In order to get seats together we had to move from row 17 to row 43. The plane was freezing."
Cons: "Husband and I upgraded our seats, only to board and settle in and be asked that one of us leave the seat we paid for because they made an error and double booked one of the two seats."
Pros: "Quick problem solving and excellent service when my assigned seats were not the same on the boarding pass. The awesome safety video from around the islands. The crew was very efficient and kind. The breakfast mea was just right. Milk with good coffee! Especially liked that HA offers plenty of water! Mahalo nui loa!"
Pros: "Fantastic in comparison to the many I have flown. Service was great, up graded economic seats had plenty of room and were fairly comfortable. Nice big plane. I did feel swished in like a sardine."
Pros: "None"
Cons: "You guys showed window available, so made the purchase. but got shuffled around to bad seats when it’s time for my flight. Screw you guys!!! That is how I really feel"
Pros: "The fact the plane arrived in Honolulu ahead of schedule. Boarding was quick and efficient and the crew was about par with other experiences."
Cons: "The entertainment screen did not work. The conditions on then plane were warm - was the first flight ever taken where it was not cool. The food was unappealing."
Pros: "Pleasant staff, lights were dimmed for rest cause of early flight and comfortable environment."
Pros: "I like that they gave a meal during the flight, especially since it was a 6 hour one. Food wasn’t too special: a hot sandwich, chips, and cookie. Good overall atmosphere. Attendants were friendly and helpful."
Cons: "When checking in, there wasn’t any seats available. Needed to wait at the gate to finally get seat assignment, after boarding already started. Traveling as a party of two, was lucky to be able to sit together for a full flight. Also, all entertainment options cost money. For other airlines, some cost money and some did not. For a long flight, I would expect free entertainment, but I might be spoiled by flights to China."
Pros: "The service was good"
Cons: "The plane maintenance for the video equipment seems to be lacking and the plane interior was dated."
Pros: "Good price, friendly crew, clean"
Cons: "Cabin was freezing cold, no blankets, food terrible, plane malfunction caused 1 hr delay; poor communication caused serious stress"
Pros: "Friendly service. Clean nice plane."
Cons: "The landing was harsh."
Cons: "TVs should not charge to watch anything (many other airlines offer this). Also, offering wifi would be a big improvement."
Pros: "Nice seats, and staff and good food."
Cons: "Plane should be equipped with wifi."
Cons: "Why is there no complimentary food service on a 10 hour flight?! If I was flying internationally there would be two complimentary meals served."
Pros: "Loved the free guava-oj, real props for safety features, and friendly flight attendants. Smooth flight on time and comfortable."
Pros: "The crew was friendly, and I appreciated the in-flight meal."
Pros: "The seats and space were great. The crew was amazing"
Cons: "The plane was very hot and uncomfortable. When asked to turn the a/c temperature down, it took about 20 minutes to become comfortable, but then about an hour later it started getting warm again."
Pros: "That you fed us even if the quality was just fair."
Cons: "Cramped seating"
Pros: "The crew was very pleasant and very helpful getting us to our connecting flight to Kona since we arrived late, due to equipment problems leaving Sacramento. A free meal was a welcome surprise."
Cons: "Cancelled our flight, after that we didn't get our luggages ☹️ That's why we didn't take part of our trip to Polynesian Cultural Center, the flight was delayed 9 hours"
Cons: "You have the odacity to charge for entertainment on a trans-pacific flight. Your crew members did a poor job of redirecting the travelers-- they were constantly ignoring the seatbelt sign and were standing during landing."
Pros: "I loved this airline. The crew is definitely Aloha Spirit minded with Fierce resolve and great food, on time boarding and landing and I got the best blanket from Moana Mahalo, Linda"
Pros: "Great crew. During meal time they did a great job of having passengers adjust their seats so people could eat their meals in economy. If they didn't do this, it would be left to the passengers to ask the person in front of them to raise the seat or have to struggle to eat with that person's seat close to your face. Having the crew do that was great. That is another thing nice with this Hawaiiian aircraft. The seats actually have leg room in econonmy and they recline enough to rest. Don't change that! Also very nice is that you get a complementary wine or beer with your meal :-)"
Cons: "Entertainment options felt like 'nickel and diming'. It is a 5+ hour flight and all the seats have personal entertainment consoles. The only thing is you have to pay ~$7 to watch any of the movies. Be sure to have your book or device loaded up before flight. Each seat has a USB charging port :-), however it only has low amps - this means you can't charge things like a tablet :-(."
Pros: "crew was friendly and helpful and the seats in economy plus were more than adequate."
Cons: "nothing"
Pros: "Plane got turned around after 3 hours in plane. Had to change 2 flights, my rental car reservation, 2 doctor appointments with no sympathy or even care from Hawaiian airlines. Spent hundreds of dollars and got no compensation. Not happy and will never book again."
Cons: "So disappointed, angry, and sad."
Pros: "Loved the customer service all the way. All of the employees were very attentive and were genuinely interested in helping everyone."
Cons: "There's nothing I didn't like. I really liked everything."
Pros: "I like that we boarded on time and the flight left on time."
Pros: "The seats are better than anything I've experienced in the cattle car, which doesn't make them great, and the leg room was OK (I'm 6"). I was pleased to find out they included a meal for free, as I hadn't bought anything to eat for the 5 1/2 hr flight. Overall a better than average flight, and it was on time."
Pros: "I upgraded my seat while checking in and was satisfied with the amount of leg room I had."
Cons: "While I apprecite the airline wanting to stand out and serving food, but I'm allergic to eggs. Egg sandwiches were served for breakfast."

Pros: "Check in person was very helpful in rerouting our flight."
Cons: "Our flight was delayed 3-1/2 hours. The gate crew booked us in another flight but did not issue a ticket, so after transferring to another terminal, we were sent back to the Delta terminal to be issued a ticket to a third airline since we already missed the second flight. Then, they lost our luggage"
Pros: "Good crew"
Cons: "The WiFi didn’t work well"
Cons: "Seats did NOT recline, which seems to be a pretty poor planning for a red eye flight."
Cons: "I feel like all the problems the aircraft had it should've been repaired before trying to use it, upon boarding they told us the left engine had to be started from an external source, as a new flyer that was terrifying to hear"
Cons: "The boarding process at LAX was awful. I’m sure the horrible shuttle wait and transfer from terminal to terminal is the airport’s fault, but the airline did not do anywhere near enough to inform passengers of what was in store. It was confusing and annoying."
Cons: "They did great. The weather was poor, so it felt more like a roller coaster ride home. Made it safe and sound. Would’ve been nice to get an update is speaker about change in weather and the rough ride in store when the whole ride was so turbulent."
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: "No dairy free options!"
Pros: "From check in from Delta App till receiving luggage, very smooth and painless process. Thank you!!"
Cons: "Separated from my wife even with pre-assigned seats. And One of the stewardess would not take my banana peel and has asked me to dump it into lavatory trash myself. She did not want to handle banana peel without a glove."

Pros: "Exceptionally helpful & attentive flight attendant, comfortable, on time"
Pros: "Cannot. Figure out how to use the wifi."

Pros: "Movies"

Pros: "Good flight attendants"
Pros: "Pleasant and helpful staff"
Pros: "Once we finally departed the flight timing was excellent."

Pros: "Flight attendants were perfect"
Cons: "Beginning about 5.5 hours prior to departure I started getting text and email alerts indicating a sixty minute delay. Then thirty minute delay. Then sixty. Then none.

I said I didn’t want to pay for checking and that it contained fragile items. It was a little over-stuffed for the scale. When I went to open it and remove some bulky items to put in my purse, they snatched my suitcase away and refused to let me touch my bag. I find this to be completely unacceptable. They had the gall to suggest I go to an airport store, buy a “suitable suitcase,” and take a later flight home. They made a scene and called a supervisor who kindly and promptly let me in my suitcase. The employee then spoke negatively about me loudly to nearby colleagues and refused to make eye contact. After the supervisor let me in my bag, I got on the plane with my suitcase. At one point, this employee made me feel like I was going to be kicked off of my flight; this was so unnecessary and extremely unprofessional. AA - your employees are better than this."

Cons: "After madly rushing to get to the gate, we found out 5 minutes before scheduled boarding time that there would be a 15 minute delay in boarding. After that, we were told there would be another 30 minute delay. Once we were on board and the cabin doors were closed we were told there would be another 55 minute delay. Also, LGA is such a mess these days due to construction and would have been nice to get an email notification beforehand about it. We barely made our outgoing flight!"
Pros: "Nothing"

Pros: "On time. Good leg room."
Cons: "Valet flight, i.e. even normal sized carry-on cannot be stowed above the seat We arrived at the gate 20 min before departure, due to TSA delays.

O planning of the lack of service as simply to go talk to the manager."
Cons: "Baggage claim took extremely long time. It took a while before the baggage crew even became aware of situation."
