Pros: "Jet blue flights seem generally good. Like the WiFi access to be Able to use flight time efficiently."
Pros: "Crew was amazing. It was the pilot’s last flight before retirement, so it was fun celebrating with him and the crew. Seats were comfortable."
Pros: "Comfortable seating with lots of legroom; clean; ease of boarding and de-boarding; on time; nice variety of entertainment available ; everything was timely!"
Cons: "Some of the channels on the direct tv were not available throughout the whole flight; one flight attendant was not very friendly (she wasn’t rude either)."
Cons: "JetBlue's livery is really beginning to show its age. The entertainment screens flicker and flash and the once-luxurious leather seats appear worn. The crew is still great, as usual, and our flight in general was excellent."
Pros: "Personalized service, even in economy. Friendly faces, who seemed intent on providing the best customer service."
Cons: "Not much."
Cons: "Delay and they not even offer something to drink at the gate."
Pros: "Flight was on time, extra room seats were very comfortable."
Pros: "Crew was super nice and helpful"
Cons: "Agent at gate was hard to understand when making announcements - not due to accent or anything like that - he just spoke too quickly and directly into mic. He kept saying something about our flight moving to a different gate but it didn’t- very confusing"
Pros: "The crew was very good. The seat was okay."
Cons: "There was some sort of breakdown and the flight was delayed about 40 min"
Pros: "Not applicable since flight changed to direct flight to FLL"
Cons: "Overall not bad. Food service can be better but it is due to the pandemic currently. Overall excellent flight!"
Cons: "The crew was overly aggressive with mask policy enforcement. They patrolled the aisles and routine pointed at passengers directing them in a hostile manner to keep their masks on their faces, even when they were trying to eat or drink. They also threatened customers by stating it was a federal law several times. It was very uncomfortable to say the least. I will not fly delta again by choice."
Pros: "Crew was friendly and engaging"
Cons: "I wiped down my seat area to clean it. It would be nice to know what Delta is doing as well."
Pros: "Crew was super amazing and friendly! Very good service also!"
Cons: "No seat back entertainment.."
Pros: "Crew was exceptionally nice. Live DISH TV unexpected and appreciated."
Pros: "Boarding was very efficient. Flight attendants were helpful and kind and seemed to care."
Cons: "We booked basic seats knowing we might not sit together however we did not know they would separate children. They put my husband and I in an exit row and my daughter at the back of the plane with strangers. I was not comfortable with strangers being responsible for my child. I assumed they would seat children with at least one parent. We did ask to move at the gate and the accommodated us with the last row on the plane. No recline, no window, and right next to the bathrooms. We took it to be with our kid but this policy needs to be revised. Kids should always be seated with the adult responsible for them... who knows what kind of person might end up next to my child. Not to mention if she had needed something is the stranger gonna take care of it? It’s just a bad practice imo."
Pros: "The crew was very attentive and had great personality. They anticipated any needs we had."
Pros: "Quick and easy boarding and departing. Wonderful and friendly staff."
Cons: "Honestly, everything was great. Food and entertainment were a little lacking but for a 3 hour flight it was more than acceptable."
Pros: "Crew was very friendly"
Cons: "the seats are horribly squished and uncomfortable. It’s the only thing that makes the flight not excellent"
Cons: "Just a bunch of weather delays because of the bad storms. I did not like the selection of movies and tv shows on the delta flight. So I just listened to podcast in my phone. But other than that everything was great."
Pros: "very well trained / polite and friendly employees, i was impressed"
Cons: "no snacks wtf i'm starvin here"
Cons: "Both flights to and from Alaska were delayed. The carry on baggage fees the seat selection fees were a terrible upcharge. I will not fly Suncountry again."
Cons: "We were over 3 hours late, which was just a big bummer. The airline was apologetic about it, but it was still not ideal."
Cons: "Flight had been delayed and the rep knew it when we checked in and didn't bother to tell us. Missed our connecting flight in Minneapolis. No one even tried to be helpful.We lost money and time off our vacation."
Pros: "convenient fight times and places, crew were helpful and polite"
Cons: "no wifi, no screen, no bag of mini pretzels"
Pros: "The crew was friendly and tried to be attentive."
Cons: "I never like getting nickel and dimed for baggage and seat assignment. More than that, though, the online check-in process feels more like negotiating with ransomware. Very difficult to understand how the bag fees work, and then you aren't to allowed to check in online unless you pay for a seat assignment."
Pros: "It landed safely."
Cons: "We were over a half hour late boarding. I got assigned a middle seat, which has no room. I'm relatively fit, but I got stuck between two overweight people, Manning I couldn't move an inch the whole flight."
Cons: "The flight attendants were pushy and rude. There are no charging plugging in between seats and the seat s aren't very uncomfortable."
Pros: "The flight attendants were exceptional and I loved how the pilots kept us updated throughout the flight."
Cons: "nothing at this time for this flight."
Pros: "We loved how friendly and attentive the staff was. We were asked if we'd like to upgrade to First Class for a small fee, which we accepted. Having never flown First Class, we felt like royalty and had an awesome, relaxed experience!"

Plane had mechanic problem that was never explained. Had to bring a plane from another airport. Six hour delay. No apology for the delay. Not even an acknowledgment.

Pros: "Frustrated with one of the crew members because I was told my bag was too big. This is ridiculous because it was the same one I got on with and the plane was about half full."
Cons: "Him not worrying about my bag."
Pros: "All around terrible Airline. Canceled our flight at the last minute, all the while telling us they had it under control and were going to fly. Made us sleep in the airport all night, re check in, bags and all at 4 AM, without any compensation at all. Don't fly this Airline."
Cons: "All around terrible Airline. Canceled our flight at the last minute, all the while telling us they had it under control and were going to fly. Made us sleep in the airport all night, re check in, bags and all at 4 AM, without any compensation at all. Don't fly this Airline."
Pros: "The crew was super nice and helpful. They made an effort to answer any questions the passengers had. They made the flight home very enjoyable. I plan to fly with Allegiant again."
Pros: "Crew was good but baggage claim took forever. The seating was not well arranged. The seats were very uncomfortable. The weight limit of the bags were unreasonable"
Cons: "Better seats could be better"
Cons: "Was surprised to see 0 social distancing in the plane. It was packed and not everyone had masks. Should be mandatory."
Cons: "The ticket lady was rude just nasty and upset for no reason."
Cons: "I see no reason why the airlines cannot provide a beverage and snack - I think they still make plenty of money off our tickets and how much could this really cost them?"
Pros: "The crew was good and the flight was smooth."
Cons: "The seats were far too close to have any kind of real comfort."
Cons: "Unclear pricing for carry on bag, could have saved $30 by paying at the ticket counter (even though I was sent an eticket and boarding pass); got stuck paying $50 at the gate."
Pros: "The pilot was hilarious and his jokes really helped calm the situation when there was crazy turbulence"
Cons: "My one hour layover turned into a 4 hour past 2AM arrival time."
Pros: "The crew was super nice, they offer me to change my seat to fly with my sister."
Cons: "The pilot"
Pros: "Crew were amazing"
Cons: "WIFI please for the god sake it’s a transatlantic flight"
Cons: "Your seats are too small, but we know the airline industry is not gonna do anything about it."
Pros: "Smooth price getting boarding pass and we were anytime sit together"
Cons: "All good"
Cons: "Lots of delays and sometimes confusing communications from the airlines about departure times."
Pros: "Flight was mostly empty and it’s a short trip."
Pros: "Nothing"
Cons: "You were late per usual. I wouldn’t have a job if I operated like you. It would be nice if there was some accountability"
Cons: "The seats are extremely restrictive and in a aisle seat I had the gentleman sitting next to me with thighs touching and attendants brushing by me as I squished to left to avoid contact with him. Entertainment screen between center seat and window seat so I just didn't even try to look at it and mostly just leaned forward to have a little space. Also another inch or 2 was taken by person in front of me putting their seat back. With such restrictive space why is this even possible??? Flying has become ridiculous and I try not to as much as I can."
