"Felt safe. No bathroom lines since many toilets are located throughout the plane. Passengers did great at following the rules."

Cons: "Soda or coffee served during the flight could have enhanced their service."

Pros: "Mal servicio; compre un tickets que no permitía escoger los asientos y nos seleccionó la última fila en cada vuelo. La diferencia entre ser priority y regula es bien marcada"
Cons: "Mejor trato a todo pasajero; se reconoce las ventajas de estar en primera clase pero el servicio debe ser excelente"

Pros: "The crew was not overly friendly"

Pros: "Movies"
Cons: "Comfort. Jetblue offers betwee seats ne apacing betqeen rows"

Pros: "Great crew"

Pros: "Everything met my expectations"
Cons: "Refreshments"

Pros: "Nice service"

Pros: "Love it"

Pros: "great crew and very welcoming for me and my small dog."

Cons: "In the last months I have travel 3 times , this is the first with Delta. I can say it has been the best experience I had. Good entertainment, the access to texting and the variety of snacks make superior this airline."

Pros: "Crew was awesome. Very friendly."
Cons: "I’m 6 foot tall and I found my seat space feeling crowded. I found myself wishing for just 2 more inches of legroom. It feels that airplanes are being built for quantity of passengers, not quality of flight."

Pros: "Crew was very fast but not enough during boarding and people had brought oversized carry on luggage to the gate requiring stowing. We had checked a carry-on at check in and paid $30 while several people got theirs stowed for free which seemed unfair."
Cons: "The charging for checked luggage has created a situation that was unfair for all travellers and ultimately made the plane’s departure late. This policy drives people to bring too much luggage into the cabin, putting at risk the safety of others and delays."

Pros: "The friendliness of the passengers and most of the crew."
Cons: "One of the younger female flight attendants was rude . She was collecting trash and took my neighbor’s (aisle seat) trash but wouldn’t take mine. I tapped her elbow to show that I had trash, she looked at me but didn’t take it. She returned and still refused until I exclaimed. She rolled her eyes."

Pros: "Not comfortable a little but scary on the flight to Detroit. Way better coming back to Denver"

Cons: "Cabin was cold enough to store meat. Entertainment system was poor at best. And, of course, the seats were too small and uncomfortable. Time to start looking at other airlines."

Pros: "The crew"
Cons: "Timing"

Pros: "Crew was excellent, pilots informative, and a very smooth and on time departure and arrival!"
Cons: "Sitting in the last row where my seat didn’t recline and it was loud and no window. It was claustrophobic!"

Cons: "I was flying standby. I checked the list on line and my name was number 5. I get to the gate and there’s just a handful of customers. The agent said there was enough seats for the standbys I wait and wait for my name to be called but no luck. My name wasn’t cleared yet. Finally I was the next to last one to get a seat. The gate agent who didn’t ask for my name tells me I was all the down at the bottom of the list. While I am glad that I got on I wish I knew what method is use to get your name on the stand by list?"

Pros: "clean plane, crew was very friendly."
Cons: "no dessert in meal"

Pros: "Snacks, drink, and spacious leg room in emergency exit row. Friendly and helpful crew."
Cons: "No entertainment"

Cons: "Cabin was too hot since the very beginning. Even in first class."

Pros: "The counter assistant change my seats and my wife and me seat together"
Cons: "Hot cabin"

Pros: "Although our flight was fully booked. The crewmembers on this flight was professional, friendly and efficient. We boarded quickly and took off on time. We even arrived ahead of schedule. Each passenger was given free headphones and complimentary beverages and snacks. I love Delta they are a cut above the rest. They are constantly striving to put the customers needs and wants top priority"
Cons: "Tight seats need more legroom"

Cons: "There was nothing I didn’t like."

Pros: "I can’t make it in mexico city on tuesday, wednesday’s performance had to be cancelled and we need to pay the cancellation fee 11500 mexican pesos, please reimburse on the credit card"
Cons: "I can’t make it in mexico city on tuesday, wednesday’s performance had to be cancelled and we need to pay the cancellation fee 11500 mexican pesos of the studio and musicians"

Pros: "Arrived early. Got a beverage & snack which is becoming rarer with American carriers. Video selection was very good. Staff was nice and attentive. Overall a good flight at a reasonable price."
Cons: "Narrow corridor to seats"

Pros: "Everything escept the seat that was too small. I also had problems with the entertainment when trying to see movies."
Cons: "Seats too small ant could not watch Movies beacause the screen was defective."

Pros: "Timely, organized, polite staff and pilots. Delta gets 5 stars all around."
Cons: "WiFi wasn’t working but we were informed so not really a negative just an observation."

Cons: "Flight was delayed over 1hr."

Pros: "Buen entretenimiento."

Cons: "La incomodidad de los asientos además que la escala fue de más de 6 horas y fuimos los últimos en abordar. Para colmo los asientos fueron los últimos de la fila y ni siquiera eran reclinables. Creo que deben tomar en consideración a las personas que estamos tantas horas en la escala y permitirles abordar primero además de darles asientos más cómodos más aún si hemos comprado los boletos con tanto tiempo de anticipación."

Pros: "Giid free sandwixh. Very good entertainment system. Good seats."

Pros: "Well, the seats and the lavatories are smaller than ever. And I am quite petite."

Pros: "Excelente"

Pros: "Entertainment is very good"
Cons: "Send my carry on bag, outside."

Pros: "That the planes flew and i met my connections and arrived home."
Cons: "Below average crew with little to no interest in doing anything but getting the flight over. Cool, and perhaps lazy or tired. We were told there was not good offered on the flight because it was not long enough. Minneapolis to Spokane - seriously????5 days earlier on same flight there was full food offerings. Audio quality and ear bugs are barely useable. Very difficult to hear any of the spoken words of the movie and I have good hearing."

Pros: "Late delay notification"
Cons: "Called the airline directly to verify the status of flight within 24hrs and everything was on schedule according to them. Even tho the airport at San Juan have not night arrivals due to the effects of Hurricane Maria, and on previous days the same flight had been moved to a morning schedule for that reason. I was notified of the delay within hours of departure of the connecting flight."

Cons: "Small plane"

Pros: "The flight left on time and we got in 15 minutes before the scheduled time. Awesome service from gate to gate."
Cons: "I didn't like that I had to pay for my bags and still purchase food on plane. The price for ticket is already overpriced to begin with. Fuel is cheaper, the planes burn less fuel due to updated design and still the tickets are three times the cost of five years ago. No one should have to pay for bags period. Show that you really care."

Pros: "Movie selection"

Pros: "Product was excellent, the whole experience was amazing."

Pros: "Entertainment was fine."
Cons: "Food variety for lactose intolerant. Crew was bare able."

Cons: "No point to early arrival when plane has to wait 20 plus minutes for gate."

Pros: "El viaje de newark a san juan por united fue excelente. Por la linea aerea de American Airlines terriblemente FATAL. Habia un problema con el avion o la torre del vuelo miami hacia san juan PR. Nos ofrecieron estadia en un hotel supuestamente ellos corrian con los gastos ya q se atraso el vuelo y no fue culpa de ningun pasajero segun nos dijo una señorita del counter, resulta ser q el hotel fue el piso del aeropuerto de miami x 8 horas!!! Wow a la verdad q nos vieron la cara de bobos y nos cojieron de bobos tambien. Q trato mas injusto. No volveremos a viajar por AMERICAN AIRLINES asi mismo le dejaremos saber a todo el mundo el trato de esta linea con los pasajeros. Gracias a esto nos agravamos la espalda, costillas. Por culpa de ellos por tratarnos como basura. Eso no se hace!!!! Despues q estabamos sentados en el avion el piloto no llegaba y nos tuvieron q bajar del avion, esperar a que llegara otro piloto para volvernos a montar en el avion!!! Q mala coordinacion!!
