Airline reviews

Cons: "Again all was perfect"

Pros: "One flight attendant was adamant about a passenger across from me, covering his nose AND mouth during the flight and constantly checked to make sure he was following the rules."
Cons: "The safety instructions portion of the flight was not thorough. They just held up the large card and stood there. No true demonstration which was important to me as I was sitting in the emergency exit row."

Pros: "Social distanced seating"

Pros: "Customer service as always"
Cons: "Nothing!"

Cons: "Seats are tight"

Pros: "The crew at Missoula airport was amazing, and most friendly"

Cons: "Flight delayed 2 hours. Wifi/entertainment wouldn't connect."

Pros: "Quick and easy boarding"
Cons: "Clean the cabin more diligently. There was a open unfinished cup of soda and cookie wrappers in my seat back compartment"

Cons: "Needed assistance for limited mobility to make connections at ATL was not provided. Caused us to miss connections and had two falls trying to get around. Air France was terrible. Very limited food and beverage service left us hungry and thirsty on 7 to 10 hour flights."

Pros: "The crew was very friendly. The plane was very quiet (except for noisy crying babies)."
Cons: "Unless you can afford the higher priced "comfort class" or first class seats, the seating is very, very cramped on Delta's 757s. It's a good thing the flight was only 5+ hours (but that's not long enough to get any decent amount of sleep on this flight scheduled as a redeye)."

Pros: "Delta crews are very friendly and helpful. Seats are 'good' on the E175 plane - better than the cramped CRJ200 on some other short flights. We boarded early, left a little early and arrived early. Nothing to complain about, except maybe a crying baby behind me, but that's not Delta's fault. :)"

Cons: "Check in was terrible- long wait just for drop off of already checked in bags"

Pros: "The only thing I liked about the experience and flight was the Delta Sky Club"
Cons: "Everything"

Pros: "Loved the pilot telling us a little about the flight crew and their piloting experience(Air Force) , and how he kept us abreast of flight status/timing , as well as our location at various points along the route. The crew was very very nice!"
Cons: "More leg room"

Pros: "The crew where extremely friendly, helpful and visible. As the flight was being boarded the gate agent saw me with my cane and she upgraded me to a seat closer to the front of the plane without being asked. Those extra little touches are appreciated"

Cons: "Don't call it "food." the meals were terrible. Also stop creating so much single use plastic."

Pros: "Free wine and spirits and food really not too bad in economy Very large movie and tv show library - something for everyone Friendly cabin crew"
Cons: "Overhead bins a bit small on this older 767-300"

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: "Helpful staff"
Cons: "I didn’t have anything negative to report regarding this flight."

Pros: "No issues"

Pros: "Not much"
Cons: "Seats very uncomfortable no room to move"

Pros: "Crew"
Cons: "No upgrade"

Cons: "Last seat by bathroom smelled of urine"

Cons: "A 7+ hour delay!"

Pros: "The crew was very professional, hejpful and had good attitude towards the passengers. This made the flight easy and enjoyable."

Pros: "Our flight attendant was excellent. Service with a smile."
Cons: "We almost missed the flight sitting right in front of the gate. No announcements could be heard in the gate area and when we asked, they said they were already removing our luggage, Very odd. Food was terrible! Choices were pasta and cold chicken salad. I had the pasta, which was bland ravioli in two bland sauces. I was surprised, because I had experienced better food on recent international flights."

Pros: "Service was great, crew was responsive, snacks were good per usual."
Cons: "The AC was blasting at an all time high, felt frozen to my seat, even asked for a blanket but “ they didn’t have any more “, had to tuck in my arms into my layered shirt. this was a morning flight and no breakfast was served ... they didn’t even have food available for purchase."

Cons: "."

Pros: "They had available seats on an earlier flight and I was able to get home super quick! My checked bag also made it which was great!"

Pros: "Great flight attendants and very clean"

Pros: "We were early, I had free Wifi, I love Delta!"

Pros: "We flew Delta. My husband fractured his ankle and got a cast the day before our flight to Cancun. No turning back Our seat assignments had us separated on some segments and also at window and middle seats. On all flights we were bumped up to comfort seats with an empty seat next to us for his cast and the final flight home put in an earlier flight home to avoid a six hour layover! Delta really went over and beyond expected."
Cons: "Kayak sent me an alert to our flight telling us we left from Terminal S in Atlanta. After several joyvrides on the tram we found out there is no Terminal S!"

Pros: "Flight attendant was nice. She changed my seat to the front cause the guy behind me was kicking my chair."
Cons: "They cancelled my flight from the day before and when they rebooked my flight, they could of gave me a better seat."

Pros: "Flight attendants were really kind"
Cons: "We were an hour late to leave so I missed my connecting flight and am currently stuck in Minneapolis for nearly 8 hours now"

Pros: "Although the flight was delayed, when it was time to board and take off, this was extremely efficient."
Cons: "Delayed flight. However, I know this sometimes out ot the airlines control."

Pros: "Excellent landing into Butte Mt. Very smooth landing over gorgeous mountains. The pilot flew us directly over some of my favorite Hikes near the Continental Divide."

Pros: "Great flight attendant great people"

Cons: "Delayed flight, customer service was hard to work with."

Pros: "Good food and movies. Comfy seating with plenty of room."

Pros: "Variety of entertainment options, much was complementary, which was definitely a neat addition."
Cons: "There was a bit of a delay right before boarding, which was not the airline's fault, but air traffic control at the destination. Unfortunate, but things happen."

Pros: "Everything"
Cons: "Nothing"

Pros: "Nice staff (check in counter and flight attendants) and good food and smooth ride"
Cons: "I wasn't allowed to bring my hiking poles onto the flight and they didn't fit into my checked bag."

Pros: "Smooth flight."

Pros: "Very friendly staff and the onboard meals were surprisingly good. Korean Air may quite possibly be my favorite airline."

Pros: "Comfortable flight, super crew, awesome non stop flight from Minneapolis. Could not ask for any better. Delta is the #1 airline."
Cons: "Nothing at all."

Pros: "Plane was clean. Hotel due to missing connection was nice."
Cons: "Flight delays cause cascade of irritable passengers. Flight out of Phoenix delayed due to late departure from previous location. We were told mechanical reasons was the cause of the delay. This caused many passengers to miss their connecting flight in Atlanta. When we arrived after midnight, one gate person was attempting to help 50 people with morning connecting flights and room accommodations. The airline knew 3 hours prior that they would have tired, hungry, frustrated passengers. To then have to wait more than an hour in a line to get a bed and or a meal was too much for most people. There were other smaller examples of how Delta's staff or procedures were not customer centric. I will avoid Delta for travel in the future, and I am getting out of their stock."

Cons: "Why can't all the Delta gates be near each other. My connecting flight was very far."

Pros: "I fly Delta Airlines 2x a year and if I had to go on this flight experience alone I would never fly with them again. This particular flight attendant. Brunette who wore all red~ like she had a personal conflict with us from the moment we walked on the plane. We were sitting in the back and could hear the things that she was saying about my grandson and myself. She was rude, snotty, had a sassy mouth. I was COMPLETELY APPALLED as to the way we were treated by her. It was a long flight to have someone you felt was bullying you the whole flight to the moment we were exiting the plane. Karma will come back to her one day..."
