Pros: "Being on time with everything."
Cons: "Nothing"

Cons: "Really felt happy on time touch down nice journey with delta"

Pros: "Friendly crew"

Pros: "The crew was amazing! The seat was comfortable."
Cons: "Used the self check in kiosk to begin! That was awesome! But after that I still had to stand in line to check in my bags. That part of the process took a bit longer than expected."

Pros: "Nothing special"
Cons: "That was the most uncomfortable and cramped seat I had ever had on a plane flight. Even sitting on the pillow did not help."

Pros: "I like that I arrived at my destination safely."
Cons: "My allergies were bothering me due to the airlines allowing animals to travel as passengers, in this case a rabbit. I am very allergic to animals. My breathing was compromised."

Pros: "This had one of the best attendants I have encountered. She was extra friendly and made us feel good."

Pros: "Everything went smoothly."

Pros: "luggage was there when I got off the plane."

Cons: "The flight was 2 hours delayed.. this cause a lot of inconvienece.."

Pros: "Staff were friendly. Nothing they could do about the maintenance issue that we experienced."
Cons: "Hour delay due to a maintenance issue. This was a hassle in and of itself, but the flight was also on New Year's Eve and ended up getting us to Buffalo about 20 minutes before midnight, which was a bit disappointing when I had made previous plans for the night. Also, I found the cabin to be very cold during the flight, but it was pretty short so I didn't complain."

Pros: "Everything was on time and efficient. I also liked that the captain came on and updated us on arrival, turbulence, weather, etc."

Cons: "The flight dely 1 hour"

Cons: "Flight was delayed out of St. Louis causing several of us to miss our connecting flight from Salt Lake City to Portland. Delta was of very little help in assisting us in making a connecting flight. They could have at least helped with travel arrangements and provided us with a little food, a pillow and a blanket as we waited in their terminal for the next flight on their airline which was a several hour wait. I understand these things happen but the passengers didn't cause the problem and Delta needs to take care of people better if they expect to earn repeat business."

Cons: "My seat ,the distance to get to the gate, The wheelchair l No window The distance I had it walk to get to my seat I was told this was the row behind the break after the exit row. I was not I’ve been with you before and have not any of these problems No more"

Pros: "The pilots were communicative of why and what the reasons were of delays as far as the landing and getting the plane to the gate."
Cons: "Attendants that offered drinks and snacks offered me coffee or water but didn’t offer a snack. But asked the girl next to me if she would want one. No consistency"

Cons: "Ac not working at last 30 minutes of flight."

Pros: "It was a short easy flight that actually landed early."
Cons: "Nothing"

Pros: "Nothing"
Cons: "We lost our whole vacation and had to pay for the plans fare twice because My last name was spelled wrong on our tickets and we were unable to use them because my passport didn’t match the name on the ticket. We had to rebook everything pay almost twice as much for the plane fare, our Lodi g cost more and our trip was delayed for two weeks. Vyama is blaming us for spelling our name wrong and claimes that it’s our fault this happened because everything is automated. There saying they don’t touch anything that we enter into the booking but somehow everything they claim we entered is now in all capital letters and the space between our first name and middle name is now gone and all run together. The coustomer service number gets you to someone in India. I have tried to get this addressed four times now at first they tried to place the responsibility on the airlines now us and they have hung up on me twice. Kayak has been worthless, they also just pass the responsibility on to someone else. We will never use them again ant I intend to make sure that this mess is put out in social media to hopefully keep others from having their travel plans ruined by their flawed system."

Cons: "They changed my flight to a different one departing 2 hours earlier and did not notify me! The original flight was still available & they would not let me take it despite my reservation paper work. CRAZY! I have a two hour drive to the airport this gave me the option to leave home at 2:30am or go the night before and pay for a hotel. Flight was managed by DELTA who also did not care! All involved blamed each other. Beware"

Pros: "Our flight attendants were lovely people specifically the first class attendant and he was humorous and witty, polite and friendly trying to make our christmas eve late night flight to be enjoyable."
Cons: "When we touched down in a blizzard we were told there was no jetway available and we had to climb down an icy ladder to walk probably 1000 feet on black ice barely seeing where we were going and at least one person fell and overall it was just very unprofessional and not the quality of service I expect from Delta."

Pros: "All the staff are sincere in serving. It must be a direct result of the great management at the top. If the employees were unhappy and rude that also would be a direct reflection of the management. I use the same flight often and let the staff know I appreciate them."
Cons: "Snacks are small, but delicious cookies."

Pros: "In flight movies"
Cons: "The flight was 3 hours late taking off which made us miss our connection to chicago so we are stuck in Atlanta tonight with unplanned expenses we were not planning on!"

Cons: "I paid extra to sit comfortably only to have the seat adjoining my occupied by someone who expanded over onto my seat! Leaving me barely any room to sit comfortably."

Pros: "Very friendly crew"
Cons: "Seatbelts very short given ample seat size"

Pros: "Everything from the check-in to the landing was great. We were well informed about what was going on with out luggage (we were on a regional flight) and the assortment of free snacks were superb! I guess I'll be a returning customer"
Cons: "I was expecting some form of entertainment (radio, overhead monitor, etc) on the CRJ700. But it really don't take away from the experience since T-Mobile partnered with the Wi-Fi service and I received a free hour of Wi-Fi!"

Cons: "My flight got to New York so late!!!! I missed my international flight."

Cons: "Not great communication from gate or staff on board. Failed to provide adequate water. No ice on super warm flight. Just bad experience overall."

Cons: "The flight was over 20 minutes early"

Cons: "We we missed our connection they wouldn't help us at all."

Pros: "The only flight that was a bit better was from Mumbai to Hyderabad."
Cons: "Almost the entire trip, due to the following reasons: 1. The online check in process didn't work at all. The Delta staff at the Boston airport weren't pleasant and courteous at all. 2. Poor coordination between Delta & Jet Airways - the meal preference was selected before flight at the Jet Airways website but the same didn't get registered properly, even though the website confirmed to me that it was all set. This resulted in appropriate food not being available to the customer on the flight from Boston to Amsterdam. The customer had to literally starve on the flight. 3. The pursers and stewards on the flight from Boston to Amsterdam weren't pleasant and courteous at all. For anything they were asked, their responses ."

Cons: "Not a fan of the distance between our arrival gate in ATL and connecting flight to BUF. Couldn't be helped, I suppose."

Cons: "Nothing just great"

Cons: "Not enough water on the flight and we landed in a parking lot and shuttled back to the airport."

Cons: "Boarding process was very sluggish causing us to be delayed."

Cons: "turbulance"

Pros: "Was able to get on a flight after ours was cancelled. Delta was in scramble mode and their gate staff worked hard ot deal with a frustrated flying populaiton"
Cons: "After paying for first class round trip airfare, we were given seats in coach in the rear of the plane, in spite of empty seats (plenty of them) in first class and economy comfort."

Pros: "I was cleared for standby! Flight attendant at the stl gate is always friendly and willing to help! I love her!"
Cons: "I waited almost 6 hours on the phone the night before the flight to get on standby! Almost didn't get the flight! Was charged $50 only to not get on my next flight because it was over booked! Flight attendant was very rude!"

Pros: "I liked that I was able to get able to get an earlier flight!"
Cons: "I don't like that I had to pay $50 extra dollars for standby on both legs of my flight! I am a very loyal delta customer and these past times flying I feel like my favorite airline is turning into the bad airlines delay everytime, problems with the plane fare prices too high! I'm starting to think about taking my business elsewhere!"

Pros: "10 minutes early departure"
Cons: "There isn't enough seats in the gate area and sitting on the runway for 10 extra minutes we could have been early"

Cons: "Seat should with choice."

Pros: "Nothing"

Cons: "4 hour plane availability delay - of course planned on weather but not planning"

Pros: "on time, even a little early"

Pros: "On time. Friendly and attentive staff."

Pros: "A cheap option to upgrade to 1st was offered that ended up being a net 0 cost upgrade for me so I took it. Comfortable on an old (but oh so nice) aircraft."
Cons: "Arrived 30 minutes early to the airport but then had to sit at a remote pad so that we ended up being 5 minutes late to the gate. A short transfer was made even more difficult, and a massive waste if time and fuel sitting and waiting. Figure out your gates early and better, and move around if needed. At the very least, bring up some stairs and buses to get passengers to the terminal and then tow the aircraft in when you have a gate available."

Pros: "Room between rows Entertainment from St Louis to Phoenix"

Pros: "Fast"

Pros: "The crew was great"
Cons: "The seats were not comfortable and boarding was a pain. Not sure why you wouldn’t want to board from the back to front. Weather grounded us at our loading airport so we were stuck with the option of staying the flight or going in the lobby."

Cons: "Boarding is always awkward on any airline. If you boarded back to front and deplaned front to back, time and aggravation would be reduced."

Pros: "The pilot was great. Avoided turbulence and arrived about 20min early. Easy to find seat and stow bag. Smooth takeoff and landing."
Cons: "Alaska airlines was who I thought I was riding with but the itinerary changed past min. Gate change and the airline itself was changed. Really confusing since I printed my boarding pass the night before."

Cons: "The video monitor for my seat was broken. So, low entertainment score."

Pros: "everything was on tyime"

Pros: "A nonstop flight, with a friendly efficient crew, met my expectations. A crew member went above and beyond when I asked for a coffee stirrer with my coke and ice."

Cons: "Delayed a total of four hous!"

Cons: "good"

Pros: "Flight was on time, staff was friendly and boarding was organized."

Pros: "On time arrival"
Cons: "Everything else"

Cons: "Everything was great."

Cons: "Only suggestion would be to make the connection process a little easier. If the passenger doesn't speak English, the fact you need to print the international ticket in Miami, then re-enter at checkpoint might create confusion."

Pros: "On time. Good leg room."
Cons: "Valet flight, i.e. even normal sized carry-on cannot be stowed above the seat We arrived at the gate 20 min before departure, due to TSA delays. But they closed the door and no one was around to even talk to. At least they put us in the next flight.... Still, as we're not checking in any bags, they could have let us in."

Pros: "Very comfortable"
Cons: "Kept asking passengers pretty boarding to check luggage due to limited space...yet after we boarded there was at least 1 completely empty overhead compartment."

Pros: "Non stop"
Cons: "Airline"

Pros: "On time."
Cons: "Seats are not roomy, but that's par for the course."

Cons: "Boarding took forever, the flight was over 2 hours late which caused me to miss my connecting flight and my military orders were not honored - I still had to pay extra to take all my gear back to my duty station. Never had that issue with any other American airline."

Cons: "No food or beverages for me. I slept comfortably on my flight"

Pros: "I don't know how airlines get away with all the stipulations and regualations they have in the buying process there is. Otho g I like about the scam artist they are"
Cons: "The fact they they can just make it a policy and then because the employees have to have a job and enforce it blows my mind. 200 dollar transfer fee plus the difference in the ticket when it's over two weeks in advance. You people are scam artist"

Pros: "You provide me with the best ticket prices and to me that was the the most important part of of the trip thx"
Cons: "The airlines charging for your luggage"

Pros: "The movies"
Cons: "No Food"

Pros: "Frankly there isn't much to say here. After 7 flights in 2 weeks there was only 1 flight with great staff that actually cared about the customers and looked like they enjoyed their job. The rest treated guests with indifference at best."
Cons: "Customer service is dreadful, the planes are so old they still have cigarette lighter charges in first (but of course no adapters), no food/snacks of any significance, and they seemingly cancel flights at a whim with basically no staff to help re-book the lines of guests that have been disrupted. I pity those who loose luggage AA baggage services are flooded with lost baggage they just don't care any more. Seriously its embarrassing how little they care about customer service."

Cons: "Flight was delayed."

Cons: "Delayed"

Cons: "You couldn't hear anything as people boarded."

Pros: "All great."

Pros: "Everything was timely."
Cons: "No complaints"

Pros: "Crew was nice, but could tell they were tired."
Cons: "Waited for late connecting flights almost 40 minutes (15-20 people). First class seats were like bricks - lower cushions need upgrade or replacement. Very hard landing including a good pavement “bounce”. Not what I would consider first class accomodations all around. 3 different baggage claim turnstiles until they finally got it right."

Cons: "Late"

Pros: "Everything was excellent! I even got upgraded to a window seat!"

Pros: "My wife was happy"
Cons: "Fixing my own supper"

Pros: "Service was excellent"

Cons: "Such a downgrade from other airlines! Awful! They board backwards. Usually the back seats board on the plane after the special needs people. Makes more sense, people are out of the way. My water was poured into a cup from a big water battle. I like how Jetblue gives me a personal water bottle and a variety of snack option. I was given a "snack mix" on this flight which was not good. I hated this flight and there were NO televisions, or usb ports to charge phones. Never again. They didn't even have enough room for carry on bags for everyone. Thank god I packed light and didn't need to use that option. Good to know United Airlines has crappy everything."

Cons: "Never on time"

Cons: "Flight was cancelled. Waited on phone twice for 45 plus minutes to find alternate flight."

Cons: "Disorganized boarding. Changed gate without notifying anyone. Running around trying to catch connection with very little time."

Pros: "Nothing"

Pros: "Rain delayed our take off but most of the time was made up. No complaints!"
Cons: "Forced to check our carry on suitcase even though there was plenty of room above the seats."

Cons: "While people were waiting on delay their was no effort made to get people seat locations. When time to board their was a line of 30 people getting new seat location before they could board the plane. A seat location I had for 3 months and checked in Ft. Myers 8 hours earlier was occupied so I was told very rudely to get in line behind 30 people to get new seat location. It took over an hour to board plane before take off. There was non English speaking customers who received no help boarding plane finding seats because crew was laughing joking with other passenger. They tried to put a non English speaking passenger in exit row. I paid $25 to check a bag to find passengers getting free bag checking at gate."

Pros: "Courtesy"

Pros: "Newer plane,"

Pros: "I wrote my review above"

Let us know personally why we keep getting held up for take off, why we are being left in the dark, andehy you can't schedule more accurately!

Pros: "Excellent price and an overall smooth process. The Frontier app has gotten a lot better and I'd like to continue seeing improvements."

Pros: "I guess you still what you pay for"
Cons: "We boarded our plane at like 3:20-30 and we did not leave till after 5:15... ridiculous. delay after delay and no complimentary anything just a bunch of we are sorry's. It made me late for most of my evening in Denver so not a very happy customer"

Cons: "No wifi available to purchase"

Cons: "The hidden bag fees"

Cons: "Nothing"

Pros: "I got where I was going to."
Cons: "One zone isn't even through the door and the next zone is called and all we do is stand in the very hot jetway for nearly 15 minutes. Being charged to pick our seat and for our luggage is ridiculous. It should be included in the price, if you have to raise the price then at least people would know better the true cost of their travel. Being charged for a drink! Having $1.99 put on a credit card!
