Airline reviews
Cons: "Nothing. Smooth flight, friendly crew, and early arrival. Can’t be beat!"
Cons: "Nothing. Smooth flight, friendly crew, and early arrival. Can’t be beat!"
Cons: "Flight was delayed and loud large family group was disruptive to other passengers."
Pros: "The seating was a lot more spacious than on the Delta flight we took to Portugal three weeks ago."
Cons: "The gate agent got the boarding group messages mixed up on the display screens, which allowed some people with C boarding numbers to board with the first group of As, but aside from that minor issue everything went fine (it was a full flight, and too many people carried on luggage, as usual)."
Pros: "Affordability was the strongest motivator in choosing Southwest."
Cons: "I hate that you have to pay extra for the opportunity to sit together with fellow travelers."
Pros: "The crew was really friendly and wanted to ensure you were comfortable."
Pros: "Very smooth, quick flight. Very attentive, friendly flight attendants. Overall great experience!"
Cons: "Nothing"
Pros: "Very sad experience"
Cons: "The boarding in FLL was a mess. The gate attendant was terrible and did not oversee the boarding. result was overage of cabin baggage. During the process of boarding, one passenger was apparently injured due to a falling article from the bin caused by an incessant and non contained effort that went on for some 5 minutes of a passenger trying to JAM a bag into a space. No Flight attendant intervened. The flight was delayed for 1.5 hours because of the injury (minor and a bit overdrawn) which resulted in waiting for medical attention at FLL. The entire flight was held. The pilot and the flight attendants did not address the issue and resulted in just sitting on the plane with little or no explanation. Clearly there was a liability concern by SWA, as they had a ground supervisor enter the plane and realign baggage in the bids. The Flight attendants were very short and non courteous to passengers. The pilot was not present a exit of the plane.. We were terribly delayed and it was due to mismanagement by the flight attendants and the ground crew. The in flight service was horrid. Someone needs to look into this."
Cons: "On flight WiFi didn’t work. It was a minor inconvenience."
Pros: "Friendly crew"
Cons: "Little legroom and the flight was delayed could connect to the wifi"
Pros: "Because if a flight delay I would miss my connector from full to Jax, so I was rebooked EWR to IND, TO BWI TO JAX. I was flying from 1 pm until 10:30 Pm to get from EWR to JAX. Had 3 takeoff and 3 landings. So ridiculous to have to go to Indianapolis to get to Jacksonville!"
Cons: "Flying ALL DAY!!!!"
Cons: "First class in an airplane this size is a bit limited (especially legroom) when in the first row."
Cons: "Had to pay 100 for overweight bag fee which is a lot. I knew it was large but I had to put all I. There as I had a serious should injury and could only manage a very small Carey in. I was only over by about 5lbs"
Pros: "We landed 45 minutes early and the flight attendants were great"
Cons: "Flight on time and not wait 30 min on the runway to get to a gate once landed"
Pros: "The seat was nice."
Cons: "Offered water or Orange juice in a can due to a short flight. I may recommend no canned orange juice, due to the quality ingredients and something more freshly squeezed for health benefits. And offers coffee or tea."
Pros: "Crew were very attentive and hospitable to the crew. I have been flying ASIANA many times and enjoy the flight as well."
Pros: "NOTHING ㅗ"
Cons: "GROUND SERVICE. The flight was delayed causing me to miss my connecting flight. The ground staff at BWI said they could do nothing about it. I spent an extra $1000."
Cons: "Really old plane. Not well cleaned. Bring sanitary wipes for seat and tray tables. But cabin crew is top notch."
Pros: "Flight was ok."
Cons: "They took away our seats and then gave us new ones but we were separated. My son is 2 and I was t able to sit with him and my wife."
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."
Cons: "the flight was 2 hours delayed but the staff continuously kept us up to date"
Pros: "Paid seat was comfortable, entertainment was great"
Cons: "The elder gentleman was very rude throughout the flight. Paid for front row seat mostly due to covid and he made us seat and wait for people that had a connection flight to exit the plane all the way from the end of the aircraft defeating the purpose of me buying the front row seat at $65 which was more than the seat was worth. The way the crew asked was was very rude because he stated if we stand up he would keep the door closed. I understand about the passengers with connection flight but its Jetblue responsibility to get these people to their connection but it shouldn’t jeopardize me."
Cons: "It was a 6 hour flight and I didn’t know only 2 snacks and a water were available on the plane until I got to the airport. Almost everything was still closed at the airport. We were quite hungry and thirsty."
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."
Cons: "The video screen at my seat did not work. Otherwise the flight was great"
Pros: "It has been over 2 years and I still remember the service, comfort and atmosphere of this flight. Whatever JetBlue is doing, it works!"
Cons: "Service was the best!!! Eatup cafe option wasn’t printed on the menu. Elf the movie was an option on my tv but wouldn’t actually play."
Pros: "I liked the male flight attendants on my flight. They were nice and cheery and was always willing to help. The inflight entertainment and WiFi was great. The snacks were also good."
Cons: "I forgot to the flight attendant’s name but she was quite rude. I traveled with an infant who required warming up of her milk in a bottle and I would ask for hot water and she failed to bring it over. I requested hot water twice. Initially when the plane was taking off- she stated she cannot bring anything while the flight was taking off but even after take off and in cruising altitudes she did not come over until we rang the call bell and another flight attendant came over. Second time mid flight we happen to ask the same flight attendant for hot water as she passed by— she nodded her head but again never returned with the hot water. Again I hit the call button and another attendant came over and gave me water. I felt that she did not like attending to the flight guests and always seemed to give an attitude. I understand traveling with a child may be hard for others, but imagine the parents who have to care for a starving baby. The flight was also a bit too warm."
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 very friendly and responsive"
Cons: "Would’ve been nice if they offer headphones. Maybe they did and I just didn’t notice."
Pros: "When I asked for a seat change the crew was very accommodating"
Cons: "With covid in Seattle I was placed next to a restroom. I did not see any bathroom sanitation occurring during the flight, and no sanitizer available anywhere."
Pros: "The crew was great. The pilots too."
Cons: "The audio and video at my seat did not work correctly."
Pros: "Crew was very friendly and took good care of the passengers"
Pros: "Crew was great, check in was fast. Overall great experience."
Pros: "Seat was comfortable, boarding was good"
Cons: "WiFi didn’t work, my tv didn’t work either"
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: "Flight was good and crew were good. Nothing very outstanding but by no means a terrible flight."
Cons: "The in flight screens weren't working well."
Pros: "Delayed boarding but made up for lost time in the air"
Cons: "Delayed boarding"
Cons: "We weren't alerted there was a chance of delays. Over two hours late."
Cons: "Just hate the super smaller seats and the reduced spaces everywhere"
Pros: "The flight got delayed and than it was also late"
Cons: "Be on time"
Pros: "When I checked in for my flight I was given another passenger’s ticket (very similar name) and my checked bag was then sent to this other flight destination. when I got to my gate (correct destination) I discovered the error. The gate crew worked hard to get my checked bag off the wrong flight and rerouted to my flight within 20 minutes of my flight’s departure."
Pros: "Check in was easy and quick"
Cons: "Plane could have been cleaner. Price is ok, but not as good as it seems once you add luggage."
Cons: "Didn’t enjoy the flight at all. Seats were uncomfortable, staff looked somewhat unkept and were gossiping loudly in the back during the flight. Snacks were not provided, only one drink for the entire flight. I will not be using Sun Country again."
Cons: "I missed the flight because they did not allow online check in. The check in closed 45 min before the flight and I got to the airport 35 min before the flight because my first flight at LGA was cancelled and I had to spend $250 to uber yo EWR. They charged me $200 and only refunded me vouchers"
Cons: "Cramped seating, limited overhead bin space, mediocre experience. Next time I’ll spend the extra money and fly Delta."
Pros: "Crew was great!"
Cons: "I didn’t realize I had to pay for a carry on"
Pros: "Two and half hour delay, they charged me 35.00 for one carry on luggage"
Pros: "Boarding was easy and the flight was comfortable."
Cons: "The upcharges for carry on and a “seat fee”. My flight costed $100 extra!"
Pros: "Flight was on-time."
Cons: "Check in crew were robotic, lacked enthusiasm. Is management competent? Are they leading, or directing? There is a difference, and one is more effective than the other. If morale is low, if employee satisfaction is low on what is visible to the passengers; then I wonder about what passengers don't see: maintenance crews, safety, quality assurance. I heard lots of grumblings from other passengers about bag policy. Provide first class service to your employees, and they will provide first-class service to your customers."
