Cons: "I paid extra to sit in the front of the plane and the flight attendant kept an egregiously bright LED light on that shined in my face the entire 4+ hour trip. I was really tired and extremely upset that there was no curtain or anything to stop this light from shining directly at my seat."

Cons: "Maintain their planes, we were delayed more than 3 hours and this was such a poor way to handle it."

Cons: "Three gate changes and then delays of ramp connecting to plane. It was ok"

Pros: "Seats were pretty comfortable as plane seats go. And overall the plane appeared very clean"
Cons: "Multiple delays, which is really nobody’s fault if it’s weather related but it causes multiple gate changes. We were traveling with an infant so we expected to get seated together, we got the same row but had an elderly person between us. We kindly asked if she would want to switch seats which she was fine with but who seats someone like that?! overall it wasn’t terrible but it felt like nobody has their stuff together and 5 hours were added on to our travel day"

Cons: "Left 5 hours late. Not notified til I left for airport. Sat on the plane almost 90 minutes before we took off. Flight was good"

Cons: "The flight was delayed for quite awhile. I had been traveling all day and I just wanted to go home. We also were not informed why it was delayed for so long."

Cons: "Tv’s were fickle and my other seat had no audio."

Pros: "The flight was on time, and we boarded quickly and promptly."
Cons: "They sat me next to the bathroom which I found really disgusting. It was hard to eat while listening to people endlessly flush the toilet. Disgusting."

Cons: "Just flying with no 3h delays."

Pros: "Crew was great."
Cons: "Everything was fine. It was a smooth trip to Denver."

Cons: "Woman next to me overflowed into my seat."

Pros: "On point"
Cons: "Keep the good work"

Pros: "The crew was great. They let me go back to see if I could find my laptop that JFK TSA did not return."

Pros: "My seat was broken, so I couldn't recline, which made my lower back ache. The TV was fuzzy and several channels didn't work, and others would cut in and out"
Cons: "Took me asking twice where my coffee was. Flight attendant forgot."

Pros: "The JetBlue crew as always was friendly and helpful. Love the snacks. We like JetBlue far more than other airlines. This trip was partially due to a credit from a previous trip, which was cancelled due to medical issues. Getting a credit was very painless, and the agent was sooo courteous and helpful! Just a great airline!"
Cons: "Logan needs to be updated. The concourse is old, worn out, disorganized. Due to weather our flight was a bit late, but everyone kept us well-informed. A most pleasant surprise compared to a certain "Untidy" airline with cramped seats, lots of extra charges, late flights, and a crabby crew."

Pros: "The cabin crew came through to collect waste from the passengers and made an effort to separate recyclables from trash. Air travel generates too much waste so it's nice to see JetBlue making an effort to reduce waste."

Pros: "There was free internet in the flight! In addition to movies and what not."
Cons: "It only flies out of JFK, and it is a bit far for me"

Pros: "The leg room was great, and the trip was enjoyable."

Cons: "We taxied for 40 minutes before taking off without getting any information about why we weren’t moving."

Pros: "The TV was nice"
Cons: "Some of the most uncomfortable seats both to and from Denver that I have ever sat in. Felt like sitting on a stone park bench. My back still aches 2 days later. It was a redeye, so I didn't much interact with the crew, but they seemed efficient and professional. They did not wake up during drink service, which was appreciated. Those planes suck!"

Pros: "They canceled the fly and left me in NY 3 days did not gave any reson for wy they cancel the flight and the didn’t help with hotel or noting cal"

Pros: "The seats are comfortable. Enjoyed the TV. JetBlue is our preferred airline. Haven't had a bad experience."
Cons: "The free snacks could be a lot healthier, i.e. apples, hummus,"

Pros: "We arrived earlier than expected and easy boarding."

Pros: "JetBlue did a good job, as usual."
Cons: "There was a screaming Infant in the seat next to me that continued to scream for the first hour and a half. I requested earplugs, and wore them under my 34 dB noise isolating earmuffs (which were made for use at a gun range). The screaming was still loud enough to give me the worst headache that I've had in 4 years. Once this baby stopped, the baby in the row behind me began to scream and the one across the isle from him/her joined in. I would happily rebook with JetBlue if there was an option to not be seated within 5 rows of a toddler."

Pros: "Leg room, comfort, travel time"
Cons: "Flight was late an hour, and the snacks were okay."

Pros: "Boarding from back of plane"

Cons: "you never put my luggage on my flight, so I had no clothing for the day."

Cons: "Online check in refused to let me pick a seat even though the plane was not full. It then did not generate, or allow me to print at the airport, a boarding pass. When my connection arrived at 7pm I stood in line at the gate while the airline employee working completely ignored us for a solid 15 minutes waiting to get my boarding pass. the flight then said it was delayed with a departure time of 9:05 and we did not even start boarding until after 9pm."

Pros: "Boarding first from rear seats worked for me because that's where I was sitting. Worked also for people in rows before they were announced. Gate agent didn't care I guess. My row mates get credit for sharing my middle armrests. Seats are tight. Loved the free Direct TV. Perfect for longer flights. Chose no food"
Cons: "Boarding first from rear seats worked for me because that's where I was sitting. Worked also for people in rows before they were announced. Gate agent didn't care I guess. My row mates get credit for sharing my middle armrests. Seats are tight. Crew didn't enforce the 'upright & locked' in row ahead at landing"

Pros: "Even in regular couch seats I found the leg room to be good."
Cons: "Flight crew was efficient but not particularly friendly. Could smile more."

Cons: "Had to pay for snacks and blanket, which is ridiculous. Very disappointed."

Pros: "Nice flight attendants..."
Cons: "Very cold in cabin-"

Pros: "Jet Blue treats its customers like they are real people and not just stock to be moved. There is adequate legroom. Their personnel are friendly and competent. This alone puts them above most airlines."

Cons: "Nothing"

Cons: "None"

Pros: "Everything! the best part was that the they kept the middle seat empty!"
Cons: "nothing"

Cons: "For some reason, we were asked several times for Passports. This didn’t make any sense since we are US citizens with drivers license. They even had TSA talk to us. This has to be fixed. Otherwise, Delta experience was great."

Cons: "Nothing, really. Airlines unfortunately can’t make people patient or polite, & I can’t afford a private jet, so I’ll have to settle for an eye roll or twelve."

Pros: "Everything"
Cons: "Nothing"

Pros: "room and services"
Cons: "can't think of anything"

Cons: "Even the baggage was quick (highly unusual for Columbus, Ohio)! Everything went smoothly."

Cons: "Delays due to Democrats not making deal"

Pros: "Lisa @ the Boston Delta check-in counter is AMAZING! She's super helpful and essentially saved our vacation! Her coworkers say she's the best and I couldn't agree more! Delta is very lucky to have someone like Lisa on their team!"

Pros: "Smooth flight."
Cons: "Tight seat. Small space."

Pros: "We left early"

Pros: "Arrived ahead of time"

Cons: "My sit changed last minute, noisy babies"

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."

Cons: "My luggage is lost."

Cons: "Delays, delays, delays... first class ticket from BOS to MSP got me a 6 hour delay and a middle seat in econ main cabin at the back of the plane. Delta you suck!"

Cons: "Tray table was broken, I was downgraded from Comfort plus to main cabin after a plane swap with no mention by anyone and no compensation. Flight was delayed 45 minutes because a flight attendant was running late and then to top it off, at the end of. The flight the attendants blocked anyone fromaim cabin from leaving until all of first class had departed, even when no one was coming they still Blocked it off. This is a practice I have never seen on delta and haven't seen in aviation in almost 20 years in the US"

Pros: "Everything else"

Pros: "I was thankful for the early boarding with a lap infant and was very pleased with the options for entertainment on the TV monitor."
Cons: "The main issue I had was that we sat in row 34 and the noise from the engines often made it difficult to hear announcements, even with headphones in. Look into possibly zoning the audio and turning it up a click or two for rows behind the engines."

Cons: "My wife was told she could not board our flight from Boston to Paris because her passport was expired, even though it was not expired. We were told that in Europe passports cannot expire within 3 months of your departure. However, Delta never let us know about this rule until we literally were boarding the plane. How they could not make us aware of this until we were boarding the airplane is unbelievable and unacceptable. This has ruined our vacation which has been in planning for the last six months."

We were not even offered the curtesy snake for a domestic flight by unfriendly stewards apparently unhappyted with her job. Apparanty all American carrier staffs has no respect for customers.
