Airline reviews

Pros: "Someone greeted me ..."
Cons: "For the check-in crew to be more enthusiastic, helpful, engaging and going above and beyond for their clients…"

Pros: "Although there was an issue with a passengers’ dog(who ultimately had to be asked off, before we could leave). It was handled quickly and our flight departed on time."
Cons: "The entertainment didn’t work/have a signal until our descent to land."

Pros: "The seats were comfortable, and the crew was friendly."
Cons: "Entertainment units were just there for the sake of it, and didn't actually provide any entertainment"

Pros: "Simple and easy flight, boarding on and off no big deal. Using your phone as a boarding pass is a great plus. Skipped the check-in process and breezed through security."
Cons: "Person I was seated next to, older women was really fidgeting and bumping me through the flight."

Pros: "Everything is always great on Jetblue"
Cons: "n/a"

Cons: "JetBlue is amazing and my favorite airlines for domestic travel."

Cons: "Wonderful wheel chair service."

Cons: "clearly communicate delays. We had no idea what was happening or what our options were."

Pros: "Boarding was fast and easy but that may have been because it was a small plane."
Cons: "After landing we sat on the tarmac for 2 hours! This is unacceptable. The gate was occupied by a plane having mechanical issues. This was the second time I have flown JetBlue and the second time I’ve had to sit on the tarmac for hours because of some sort of issue. Never flying JetBlue again if I can help it."

Cons: "We waited at least 8 hours in the delay and I wasn’t texted early enough to plan ahead. We waited in the airport and then we waited on the turnpike before take-off."

Cons: "legspace"

Pros: "LOTS OF LEGROOM"
Cons: "They have a habit of not being ontime"

Cons: "The new security check in with the automated bins."

Cons: "I was not on it"

Cons: "Asked the stewardess to have a blanket and water she had not brought. Service was bad ."

Cons: "2 hr delay. Poor ventilation"

Cons: "We are still on the plane. Can’t get off because there is lightning in the area. Ridiculous. It is raining lightly. I would really like to get off the plane"

Cons: "I have a problem with my ears, and asked the crew for nozzle drops, they don’t have"

Cons: "Flight over 3 hours late leaving. Flight attendants rude, and nothing comped for drinks or food to make up for it. Had to circle for 45 min due to weather. Sat on tarmac 30 mijn on other end."

Pros: "The crew could not have been more helpful and pleasant making the delay bearable as they were overtly communicative w all via text, email, and in person keeping is updated! HIGHLT RECOMMEND and will definitely be flying again. :)"

Pros: "Great service and smooth flight. On time, all good things."
Cons: "An individual who was very overweight sat next to me and took up half of my seat as well. I understand we all deserv to ride comfortably and my intent is not to shame them. That said, if someone can’t put the armrest down I think the airline should require them to purchase both seats as it’s very uncomfortable to be in the position of having no seat for the entire ride. I’m an average sized person so it was a challenge but even tiny people deserve the full seat they purchased. There really should be a rule or something."

Pros: "Night masked"
Cons: "Flight attendant was rude as hell , she looked like she didn’t know what she was doing"

Cons: "Delay and 4 hours in the craft upon arrival to Chicago"

Pros: "The crew was great, and so was a JetBlue pilot dead-heading in the seat next to me. I liked the space in the MoreSpace seat I paid for. I relieved that the upgrade seat came with boarding in the first group. Some airlines you pay for the seat, but you're still group 3 or 4 and, meaning all sorts of anxiety about the most miserable part of any flight, the dreaded fight for the overhead bins, wondering it you'll have to check the bag and then wait for it at the destination. Thank you for removing that."

Cons: "I never got the opportunity to fly because I was stuck in unusual traffic in a tunnel for over an hour just minutes from the Boston airport. I was later told there was a fire. I called the 1-800-JETBLUE number and I explained that the situation. The agent said that there would be a $75 change fee and at 4:47 pm there were no more flights out that night and that I would also be charged the fare differential the following day. I quickly went on line and found a deep discounted fare on United for $56! When I got to the airport there were several other people with the same situation. Not a enough agents on staff and no concern that I might miss my new flight on United. Thank Gid I acted fast and got another flight that evening or I would have needed to spend the night in the airport like a woman and her mother traveling to San Jose! Need more professionalism !"

Cons: "Another plane mechanical issue causing another delay of over 2 hours."

Pros: "comfort of seats"
Cons: "Morons at Jet Blue took me in wheelchair to wrong gate and left me there, but for someone passing and asking me the flight I was on and learning the Gate had changed, which was not announced at Gate E2 I would probably have missed my flight."

Pros: "Good flight. The staff was nice, especially Chris. Nice to see complimentary beverages and snacks still offered on domestic flights."
Cons: "Seats are terrible, and getting worse every year, but thats coach on all airlines not just Jet Blue. Hard armrests, weirdly shaped bucket seats which are appalling in any other position than straight up with 90 degree waist bend. Thats not how humans sit for extended periods of time. A 5 degree recline is not a recline; its a joke. At least the tray table was bigger than my phablet, unlike Spirit where the napkins look like tablecloths on these ‘tables’. Overall, it is better than the cheapest airlines."

Pros: "The crew"
Cons: "The plane being 4 hours late and then arriving in Chicago only to find out we have to taxi for 30 minutes because there is no free gate for us. I’m really tired and should have been in bed 5 hours ago"

Pros: "Everything on time."
Cons: "The seat in hard."

Pros: "Service"

Pros: "The plane had 2 wings"
Cons: "Staff is rude. Customer Service couldn't possibly be worst. All their food has meat in it. Staff is slow and incompetent. Never had a more dreadful experience with an airline. TAP IS THE WORST AIRLINE I HAVE EVER EXPERIENCED, and I fly 2 times a month."

Pros: "Jetblue left on time from JFK"

Pros: "The take off into the air was calm and not frightening."
Cons: "The flight we had scheduled with them was canceled and there was no email or form of communication sent to tell us before arriving to the airport. We found out while attempting to "check in." They were hesitant in providing food vouchers for us when our original flight that was supposed to leave early in the morning (6:30am), now left at (5:59pm)."

Pros: "Felt very clean and so glad they are not selling every seat"

Pros: "Great crew."
Cons: "As always, the seats in basic economy are as small as possible without actually being standing room only. I'm 5'7" and my knees are only about an inch from the seat back in front of me."

Pros: "It was all good glad the last leg of the trip was pleasant."

Cons: "Great flight"

Pros: "Airplane accelerated from stand-by directly to runway without preparation stop. Awesome!"

Pros: "Nothing remarkable"
Cons: "Delta was ordinary"

Cons: "Small plane, feels cramped"

Pros: "Yes"

Pros: "The crew did their best to deal with delay."
Cons: "There was an absolutely awful job done by both Delta and Kayak of informing us if additional delays, new gate assignments, when the plane would be reboarded. Also, people were quite angry that the plane had to be cleaned between the time we got off and the time we reboarded. Just get us home."

Cons: "No sandwiches for sale just snack boxes"

Pros: "Taco"
Cons: "Taco"

Pros: "Quick flight"
Cons: "Flight attendant spoke like a robot. Could not understand her."

Pros: "On time"
Cons: "Small aircraft"

Pros: "Staff, service, options"

Pros: "My upgrade and breakfast were fabulous!"

Cons: "Over an hour delay before boarding due to supposedly bad weather. Because flight was overbooked they were offering $400 gift card to change to standby on another flight. If you didn’t make that flight (evening), you’d be confirmed on a flight the following morning with one stop in Detroit (we booked a nonstop to Chicago). Uh, no thanks. Then to top it off, we’ve landed and been told that it will be at least an hour before we can deplane due to no availability at the gate (it’s 1145 pm right now). All this plus their new policy of not allowing us to select our seats because we bought the cheapest tickets. Really Delta? You go ahead and cater to the rich and I’ll choose to fly with another airline."

Cons: "Everything"

Pros: "The crew was great"
Cons: "The flight was 4 hours delayed"

Pros: "I flew on a basic economy fare (I understand the restrictions) and was seated in Economy Comfort +, so that was appreciated."
Cons: "I could see on the Fly Delta app that I had been placed in seat 10B, but neither the app nor my boarding pass gave me a group to board with, so I assumed that I needed to board with group 3, which necessitated gate-checking my rollerboard bag. Only when I approached the gate to board did I notice on the info screen that I had been "upgraded" to Comfort + and granted boarding with the Sky Priority group. I wish this had been clearer so I could have avoided waiting to board and gate-checking my bag. Minor inconvenience but room for improvement on Delta's part."

Pros: "This was not my original transfer flight but everyone was much nicer and helpful than serious and being rude. Love Delta, I did not flight United because I wouldn’t have met my United flight once landing in ATL. The Young African American woman who was at the gate was amazing and so reassuring that I would make my flight to Chicago. Would book Delta, just because of how nice she was to me."

Pros: "Flight was on time. Boarded quickly with no fuss."

Cons: "No help with baggage when boarding the plane, they hurry you up for nothing, because we had to wait 20 mi utes to take off."

Pros: "Flt on time, very nice and friendly gate agent and flight attendant"

Pros: "to their Diamond Medallion customers"

Pros: "Entertainment options weren't bad. Most of the crew was polite other than one flight attendant who seemed ambivalent and unhappy to be there."
Cons: "Three hour+ flight and just one tiny bag of pretzels? And no lemon or lime wedges on the beverage cart? Plus, I have to pay extra for one checked bag. I will only fly Delta if I have to in the future. Subpar airline."

Pros: "The boarding process was very smooth and we took off early and the crew was great and then we also arrived 30 minutes early."
Cons: "Nothing could be changed."

Cons: "As a handicaped disabled not able to walk and should be using a wheel chair,as I know from my many previous travels with other companies like lufthanza, klm..etc, I used to be the first traveller to go to the air craft when loading it to take off and the last one who would be leaving it after landing. Even when going through the check and security points I used to go in a special route especially for the handicaped but going with all other normal travelers lines with such amount of time waiting and crowdness is completely inconvenient. what happened through the trip was quit different , going with the travelers or after when they are boarding the craft make it very hard and time consuming , Wish you take care of it, as it's a very important handicaped service.

Pros: "Z"

Pros: "Big selection of movies if you have the United app."
Cons: "Tiny overheads in the 777 so they took carry-ons from at least half the people on the flight. Out of the hamburger by the time they left Economy Plus. Narrow seats, very little seat pitch. I am not quite 5' 10" and I only have a couple inches between my legs and the seatback. Similarly cramped restrooms."

Cons: "flight was late close to 4 hrs"

Cons: "I choosed this very very expensive flight because it was so import to be home in CPH at 9.00 for an important meeting. My flight from Chicago was delayed and nothing was done by the pilots to arrive on time. Despite the delay, I managed to arrive on time to my Connecting flight to CPH - only to realize that I was moved to a later flight. Now I have spent 2.300 USD on a poor flight that do NOT bring me to my destination on time. I am a frequent flyer, and will do everything I can Avoiding United going forward. Never United again"

Cons: "I found your crew quite unfriendly"

Pros: "The crew was nice, quick check ins and boarding. They were very accommodating during the flight."
Cons: "Although it was breakfast, not everyone wants sausage or the other option of fruit and yogurt. Meals should be offered in the literature provided by time, as in reality, if you're not going to sever the expansive US menu throughout the day. I was unable to order a salad at 9 am, regardless of being starving. Also I'm 5'1, there isn't enough leg room. Power outlets should not be a first class luxury, that is rediculous.

Cons: "Flights were all delayed or cancelled"

Pros: "Always the service is above and beyond"
Cons: "No complaints"

Pros: "Being upgraded"
Cons: "Nothing was bad"

Cons: "Where do I start. Let's start with booking and the lack of knowledge, inability to listen and respond in an appropriate manner, and the fact that after I asked to speak to a manager due to the previous issues with the agent, and after being transferred all I needed was some understanding and support due to a family emergency and instead I get a short rude push back and then hung up on by the manager after I expressed my struggle and desperation for help. The lack of empathy and just the overall experience was beyond horrible, and if it wasn't for the desperate situation I was in I would have never used your services."
