Scores according to KAYAK customer reviews
Pros: "Delta is doing a great job keeping everything calm and clean during this pandemic!"
Cons: "Nothing all excellent"
Cons: "It was great! Nice job Delta !"
Cons: "For options none. No drink carts at all. Had coffee once after I asked. Poor quality entertainment. Just a huge waste of money."
Pros: "Christina brown was amazing at gate"
Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."
Pros: "I always have a consistently good experience on Delta. Everything was great."
Cons: "It was a Great flight. I always enjoy flying Delta"
Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"
Pros: "Love the fact that the head rests move to support your head better."
Pros: "The seat was great, I wish all seats on the plane were that comfortable"
Cons: "Nothing, everyone was great"
Cons: "No meal option and my video screen volume did not work"
Pros: "Boarding was easy."
Cons: "I am 6' 1" tall and weigh 220, so not out of the ordinary and I felt like I was stuffed into a sardine can."
Cons: "Better screens for in-flight movies. More legroom or upgrade options."
Pros: "Entertainment"
Cons: "Boarding at JFK.Always messy"
Pros: "Boarding was quick"
Cons: "No entertainment, plane was small"
Pros: "Delta cramps people into these planes and forces you to put your bags under a seat because they stuff at the overhead spaces. They nickel and dime you for every single thing. There was even one person I saw who had to pay for his headphones to listen to the onboard entertainment. I think Delta should quit being so cheap with the profits they make and give it back to your flying customers. It borders on gouging."

Pros: "Entertainment choices were excellent, many new movies available, so I was able to see movies is been meaning to watch. There were drinks available."
Cons: "The air vents barely trickle out any air anymore. No relief to be had. Airline crews say hi and goodbye but that doesn't make them friendly."
Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."
Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."
Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."
Pros: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"
Pros: "Nothing"
Cons: "Everything"
Cons: "On time, free upgrade."
Pros: "Good abording"
Cons: "problems with seating assignment"
Pros: "The staff really helped me out getting on standby so that I didn't have to wait for a 9 hour layover. Overall great experience and great staff."
Pros: "Everything was perfect !! Staff friendly"
Pros: "Great in every way"
Pros: "It got me home, eventually."
Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"
Cons: "My daughter was stuck in SLC for 5 hours because there 1 cancelled flight and 1 delayed flight. It was very upsetting not knowing when she going to arrive in Denver."
Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"
Pros: "App is good and convenient to use."
Cons: "The app went down just as we were getting ready to board and luckily i had a printed pass and it took some extra time to check in."
Pros: "really helpful and friendly service and nice seats."
Cons: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."
Pros: "The boarding process in Atlanta was as smooth as could be expected given that it was a full flight. I appreciated the gate announcer's suggestions to everyone about how to ease the overhead baggage crunch."

Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"
Pros: "When deplaning in Denver, I was impressed that the captain was the staff who got behind my wheelchair and offered to push me up the walkway :)... New aircraft, kind staff, shorty flight!"

Cons: "Excellent service excellent pilot"
Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"
Pros: "It was on time"
Cons: "Too short of a layover in Atlanta"
Pros: "Entertainment"
Cons: "This is my third flight this year with Delta and every time we wait for the "crew" to get off from another flight. And as soon as they get there we can board. It's getting very annoying. Fix it."
Cons: "I'm tired of Delta making it IMPOSSIBLE to experience benefits of my loyalty. I flew literally AROUND the world in the past 6 months and it STILL doesn't qualify me for anything more than Silver elite? Seriously? When you use a voucher because of their error to lower your ticket price, but still pay cash for it, why does that then automatically exclude you from upgrades? Poor customer loyalty, in fact, non-existent these days."
Cons: "long wait and delayed flight"
Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"
Pros: "One male attendant from the first class cabin - super sweet and attentive to our needs even tho we're not seating in the premium cabin"
Cons: "Junior attendants in economy comfort seat - so lazy and whiny!"
Cons: "1. Boarding order is not by seating making boarding very inefficient"

Pros: "Very professional and caring."
Pros: "plane had individual movies for free with each seat!"
Cons: "I've only experienced delayed flights with Delta ... and this was no exception. It wasn't weather-related, nor a late flight delivering a plane - just no ground crew to service the plane between flights."

Pros: "Terrible company"
Pros: "The price"
Cons: "Communication"

Pros: "Planes were new and clean."
Cons: "Airport was disorganized. Check in was long and a mess at 8:30 in the evening. Long lines. Staff not helpful. No checkin kiosk to get bag tag. Probably will not fly Spirit again."
Pros: "O"
Cons: "BEFORE YOU GET ON THE PLANE SO MUCH EASIER ON DELTA I WILL NOT BE BACK"
Pros: "Like the convenience of the flights between Las Vegas and Denver. The ratings above you need to have a N/A for non applicable. We all know there's no entertainment. And the food is overpriced ! But"

Cons: "Escribo esto en español para poder expresar mejor mi indignación ante el servicio tan mediocre que recibimos. Después de que el vuelo se atrasara más de 4 horas, nunca logré entender porque fue que nos atrasamos. Nos decían que íbamos a hacer una cosa y hacían otra. Pasamos de ilusiones y luego desilusiones durante horas. Amo viajar y nunca en mi vida me había sentido tan estresado como viajando con Spirit Airlines. No solo fue el atraso del vuelo, sino que también salíamos a las 12:45pm de San José, hora a la que usualmente creo que todos almorzamos, y no se les ocurrió darnos de comer sino hasta las 6:00pm (hora de Costa Rica) y yo no se si según ellos por darnos una latita de Pringles y un vaso de Coca Cola ya se nos iba a olvidar el terrible atraso que tuvimos. Cuando llegué al aeropuerto de Miami noté que habían roto una rueda de mi maleta y se lo dije a una empleada de Spirit Arilines que no sabía que hacer así que recurrió a otra y lo que me dijeron fue que eso no era problema de ellas porque probablemente había sucedido en Costa Rica y luego se fueron. Ahora mismo estaba tratando de hacer el Check In para mi vuelo de regreso y nunca había sido tan complicado hacer un Check In, ni siquiera entiendo porque no puedo hacerlo. Entro a la pagina de preguntas y soporte al cliente de Spirit Airlines y para responder a la pregunta de COMO hacerlo, lo único que saben decir son los beneficios que tiene, beneficios a los cuales me ENCANTARÍA tener si tan solo en su pagina dijeran COMO se hace. He pagado casi $100 en equipaje solo porque nunca nadie me dijo que si lo pagaba como un mes antes iba a salir más barato, que por cierto su pagina de internet es de lo PEOR que he visto, porque después de pagar mi maleta para ir de regreso, ni siquiera me decía si se había cargado bien a mi tarjeta o me daban una factura, simplemente volví al sitio para administrar mi viaje y ahora solo estoy rezando para que cuando llegue al aeropuerto en serio el pago se haya realizado correctamente. En fin, voy a tener que seguir viajando muy seguido a los Estados Unidos desde Costa Rica y puedo jurarles que NUNCA voy a volver a viajar con Spirit Airlines."
Pros: "All was great but the extra large seat did not recline?"
