Cons: "Better snacks"
Read more about Delta
Cons: "Better snacks"
Pros: "The sanitizing of the aircraft was beyond expectations. The personal wipes were a plus so we could clean the areas around our seats to our satisfaction. The individual snack bags are a great idea to minimize handling. The boarding rear to front should have been in place years ago and the deplaning was about normal front to rear with distancing."
Cons: "All good"
Pros: "Crew was great, comfort+ definitely has more leg room."
Cons: "Beer not guaranteed on flight for Delta comfort plus."
Cons: "Seats are tight"
Pros: "Crew professionalism."
Cons: "Late flight. Unacceptable"
Cons: "My hard shell suitcase was broken during the process not sure when or where. Items in my suitcase were also damaged. The seats are so close together that it was very hard. If you are a bigger person I recommend flying first class."
Pros: "Fact that there’s a flight available to get me-from a to b, Crew were friendly-great, cabins clean."
Cons: "Expensive, Delayed flight, unable to hear and understand boarding announcements, No WiFi, and a magazine that caters to the top 5% of passengers. Then to top it off a lost bag and over 2.0 hours spent either on hold or awaiting a call back to resolve issues with my last bag-totally unacceptable"
Pros: "Nothing"
Cons: "Better customer service. Your employees should be te-trained and reminded they are in a service industry where your clients have other options to fly."
Cons: "It was canceled"
Pros: "extra legroom of comfort plus zone"
Cons: "Bordung process runs smoother now that the order is made clear ahead of time. In jfk they did not have the columns marked “comfort” “priority? “Main 3”, etc, like they had at Reagan arpoirt in DC"
Pros: "Nothing"
Cons: "They might have had a pilot so the flight didn’t take off 6 hours late. Missed all my connections. Trying it again today."
Cons: "Late boarding. Slow de-boarding."
Pros: "Nothing"
Cons: "Nothing"
Cons: "Better seats"
Pros: "Excellent hospitality I asked for a cup of coffee at an odd time, the attendant went out of his way to brew fresh pot and served me, instead of just saying "Sorry sir, we don't have any coffee at this time....""
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: "JFK to Denver the flight Attendants were once again great. Lots of entertainment choices again. The usual rough air coming into DIA."
Cons: "From JFK to Denver the seats were to close for leg room by an inch or two. The temperature was hot most of the flight."
Cons: "Not much- pretty great flight"
Pros: "The flight attendants were terrific. The food was marginal in business class"
Pros: "Everything but the consistent delay"
Cons: "2 hour delay and it being the last flight out of LAX."
Pros: "Service is excellent. And the comfort too."
Cons: "A couple of rude passengers that were complaining for everything and I felt Delta crew had to be a little more strict with that situation specially when other customers want to have a comfortable and pleasant flight ."
Pros: "The movies"
Pros: "I travel as a professional musician. I fly with American (because many booking agencies use them) I achieved status after years of their cruel methods of forcing us to check our instruments, thinking “FINALLY, I can board without being hassled about my instrument coming onboard with me.” Nope!! They fight me every time, as if I’m some guy going on vacation and bringing my beater guitar to play on the beach. They holler every time, “SIR YOU’RE GONNA HAVE TO CHECK THAT” $6,000 worth of equipment to make space for someone’s socks. (?!?!) Today, I boarded TWO delta flights and was told, “see if it fits... if not, we can gate check it for you...” YES!!! That’s all I ask!!! Just let me TRY first! If it doesn’t fit, THEN I can’t complain! Anyway, sorry for the saga! I just want to say THANK YOU! I had peace of mind ALL day! Keep up the great work! Your staff is outstanding!!"
Cons: "I didn’t like that you thought there was something I didn’t like! I’m a fan!!"
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: "Exceptionally helpful & attentive flight attendant, comfortable, on time"
Pros: "The flight was good, Boarding was smooth and fast"
Cons: "I asked one of the crew members to help me to get a better seat as I was very tired and wanted to sleep better during the flight and he didnt pay attention to me. I realized there were emthy seats available during the flight"
Cons: "We boarded on time and were ready to leave the gate early. Somehow the pilot and air traffic controller managed to take 1 hour for de ice and takeoff even though we were 2nd in the queue. No excuse!"
Cons: "I couldnt check in online and reserve my seats"
Pros: "Punctual departures. Adequate overheard space."
Cons: "Food was mediocre for a 5-6 hour flight. I expected a little bit more."
Pros: "I love Delta, especially their newer planes that have screens in the backs of headrests and free movies."
Cons: "Leg room is never enough. I'm 6'1"."
Pros: "Service"
Pros: "I love Delta airline this is what airline I pefer to go with whenever I fly anywhere they are the way for me such happy ppl and so much help."
Cons: "On one of my flights the Wi-Fi was down so it killed my entertainment but the flight wasn't long so it wasn't so bad for me"
Pros: "We were probably in the air for 30 mins; great short flight. Plane wasn’t filled so had plenty of space."
Pros: "Inflight free texting everywhere that wasn't China, decent food, funny crew (I liked the mix of American and Chinese)"
Pros: "Fast and very friendly staff."
Cons: "Nothing"
Pros: "I'm 6'6" and used to having my knees jammed hard against the seat in front of me (right into the metal frame). The knee room on this flight was better, they weren't even touching the seat!"
Cons: "N/A"
Pros: "The staff are fun and friendly. One of the hostesses stepped into the vacant seat where I was sitting and stepped back further when people where pushing by. We were almost cheek to cheek. The closest I've come to a cute bum in years."
Cons: "The gratis food offering isn't healthy - those bread pretzels, versus the almond & tomato juice I had on the next flight, with ...can't remember the name."
Pros: "Getting to the correct destination."
Cons: "The fact that the lack of knowledge regarding international travel visas by the counter staff and supervisor meant that two days of the vacation were lost. Upon arrival in China the 144 hour travel visa was granted with no problem within minutes, but the U.S. staff was completely befuddled by the possibility. The interrogation was completely stressful and resulted in a reschedule of the original flight and during the second attempt at flying even an email from the U.S. consulate with a link to the Shanghai/Chinese government immigration site was deemed "not official enough". i will be expecting proper compensation. I was once given an $850 travel voucher for voluntarily giving up my seat, and was flown first class to Hawaii, given 4 star accomodation and then flown first class on to China within 48 hours. This was an involuntary bump from our chosen flight time, all because of a lack of knowledge about current visa regulations and international law on the part of the check in staff. We have been loyal Delta users for over 15 years, and this was the biggest blunder ever. Also humiliating and extremely frustrating, stressful and a big problem with fulfilling our travel plans between son and father."
Pros: "everything on schedule; courteous staff and great pilots"
Cons: "everything was very ordinary so cannot complain"
Cons: "Missed connection"
Pros: "Service in the flight !!"
Pros: "Unlimited snacks and drinks..."
Cons: "The mediocre upgrade."
Pros: "Great helpful​ happy staff, made you feel welcome. Good atmosphere and peaceful. Food excellent."
Cons: "On transatlantic flight , seats comfortable but inadequate recline for a night flight and no footrest."
Cons: "You lost our luggage. What I don't understand is why we were not able to get boarding passes and seat assignments when we did our check-in in Sydney."
Pros: "I liked the service. It was incredible."
Cons: "I did not like the delay or the continued delay on the runway"
Pros: "As always seats are spacious"
Cons: "They weren't selling food on this flight which is entirely too long to be without a meal"
Cons: "Strangely cold!"

I'll be back

Pros: "Seats were comfortable didn’t have to pay extra for my personal day crew was polite"

Pros: "Great crew"
Pros: "The crew was so friendly and helpful and nice. Love the whole online entertainment thing that AA does now."

Cons: "The flight was delayed an hour because the flight crew was late."
Cons: "The baggage claim took forever. And the flight was late."

Pros: "Short flight."
Cons: "No concerns What I expected for a quick flight"

Pros: "great trip and crew"
Pros: "On-time departure and arrival, friendly ground staff and flight attendant"
Pros: "Nothing"
Cons: "spending $600 on a one way flight with you today has been the worst experience and rip off ever! Delayed in Hartford 6 hours. Changed my layover flight in Dallas. Now Dallas delayed 1 hour."
Cons: "Flight delayed because the crew arrived late the night before. This created a chain of events that got me to Newark 7 hrs later than scheduled."
Pros: "The seats were quite comfortable."
Cons: "My bags didn’t make any legs of the trip. AA should allow downloading the app on the airplane."
Cons: "Flight was delayed"

Pros: "Things went as they should have got a 2 hour flight."
Cons: "The inside of the plane around the air vents definitely could use some cleaning."
Cons: "Gate agent told me it wasn't his job to quickly verify if my luggage had made it on the plane after my 10 minute sprint in PHX. I know at my job, I don't get the luxury of telling customers "it's not my job", especially when the customer has had a bad experience with us."
Pros: "The airline staff was SO kind and helpful. I'm an AA fan now!"
Pros: "Enough leg room. Free movies"
Cons: "Nothing really"
Pros: "The staff was very helpful"
Cons: "I did not like the fact that, I was ask to help a non English person, whom spoke French find their way to the departure area from check in. I could not understand their broken English. That I feel is the job of the person or staff trying to check them in."
Pros: "Excellent. on Time. Friendly crew"
Pros: "Planes were punctual and smooth flight"
Cons: "don’t know! didn’t get to phoenix because of plane issues"
Cons: "The flight was a bit delayed and was not cleaned at all, may be because of short of time, but minimized the further delay, so acceptable."
Pros: "Nothing"
Cons: "The man at the gate was rude and tried to tell me I needed to pay 50$ to bring on my small purse, while his assistant said I could put it in my carry-on. Even more strict that Spieit airlines and higher prices. They didn't even bring around drinks because of "turbulence" unless you were first class. The plane shook slightly more than a smooth flight for only a small fraction of the flight."
Pros: "The crew was very nice. It was Christmas so the flight was not full."
Cons: "It was a short flight, so it was fine."
Pros: "Nothing"
Cons: "They had a delay that bumped our international connection. We had to switch airports and airlines and arrived significantly later than originally planned, causing us to miss pre-wedding events."
Cons: "After flying from Denver to Philly, I had anticipated an hour and a half layover. First email came speaking of a delay, then second, then about five emails later American Airlines notified me that there will be a 4 hour delay. To get from Philly to avoca on a flight is half an hour. On a bus, its two hours. If an airline knows there will be a four hour delay, how do you not provide that service? I watched plent of other flights go to AVP and even to Allentown, no one could offer one of those options to me? Cold, compressed and miserable experience."
Pros: "Personell at Bagage drop was nice"
Cons: "First the time between connection flights was very short. Then after just making the. Innextion sat for almost 2 hours on board . Missed introductory lunch for my new summer job at my college -"
Cons: "Essentially a bus ride with the comfort of a wooden bench."
Pros: "Prompt boarding"
Cons: "I could never sync in the entertainment app and wifi"
Pros: "- Great entertainment system and choices - Timely departure and arrival"
Cons: "- Marginal seat and leg room comfort for a 5'11'', 180lbs passenger"
Pros: "Seat was comfortable"
Cons: "Gate agent told me my bag would fit under seat but when I got on board found it would not and had to do gate check."
Pros: "The flight attendant lady from 1st class/Business held my suit jacket for me to grab on the way out. Simple thing, but very thoughtful and kind. Love it."
Cons: "The negatives are puny compared to what made me happy in this trip. Thanks AA! Please thank that nice lady for me!"
Cons: "Very old plane. Seats uncomfortable. Miserable. Would never fly them again. This was an American Airlines flight through British Airlines."
Pros: "American Airline flight was on time, actually, early departure and early arrival. Crew was friendly and helpful, and I arrived safely. There was room overhead for my carry-on. And I got a great deal thanks to Kayak."
Pros: "It was a short flight to begin with but due to winds it was delayed."
Cons: "Due to bumpy air nothing but water was handed out to cabin passengers. 1st class managed tho. We were asked to stay seated almost the entire flight, although people still went to restroom as needed. After a late night it would have been nice for a little bite to eat. But apparently mother nature thought otherwise."
Pros: "It was great."
Cons: "Everything was good."
Cons: "No Free Wi-Fi"
Cons: "Delays, delays and more delays. 3 gate changes and finally on an old plane. Avoid if you can. Only good thing about it, it was bringing me home"
Pros: "Plane was an Airbus, not a 737-8max"
Cons: "Boarding was a zoo and not on time (there or back)"
Pros: "Good service"
Cons: "Entertainment and better seats"
Pros: "Overall a quick flight crew was great always picking up trash it was clean."
Cons: "Only thing I hate and probably will never fly frontier again checking my bag was 50$ and the seats are absolutely uncomfortable I will pay a little more and fly with someone else everytime I fly because after bags it’s not worth it"
Pros: "Boarding in zone one"
Cons: "2nd most hated airline behind Spirit - they charge extra for EVERYTHING!!! Seats are hard & don’t reclibe unless you pay $20 more. Will NEVER fly them again!!!!"
Pros: "Nothing very disappointed with Frontiers service"
Cons: "From Ontario to Austin we were charge $50 for each carry on luggage we 1 for me 1 for my husband total $100 charge From Austin to Ontario carry on luggage was free why?Im filling complained about the airline"
Cons: "Flight delayed 2 hours! Seats don’t recline in coach!!"
Cons: "We arrived very late due to the airline being run so poorly. Something about paperwork according to the pilot. Now the rental car company is closed so I have to sleep at the airport and wait till the budget opens again in the morning. Frontier should put me up in a hotel as their mismanagement caused the delay not the weather. But they just said too bad because the flight was less than 4hours late. Frontier - never again!!!- plus the seats are painful"
Pros: "Nothing was 2 hrs late"
Cons: "Was 2 hrs late"
Pros: "The flight itself was fine"
Cons: "I used to love frontier but now everything from baggage policies to checking in feel like a huge hassle"
Pros: "The fair was low and boarding was efficient."
Cons: "The booking process was terrible online. There’s a charge for refreshments, the tray table is tiny, the staff didn’t seem happy, the seats don’t recline at all, they charge for carry ons, no outlet to charge my device."
Pros: "crew"
Cons: "you should be arrested for those seats"
Pros: "Comfort seating is spacious."
Cons: "Doesn’t make sense to charge for water."
Pros: "simplicity."
Cons: "help but i had to pay to change my flight during Harvey. I paid double because of it. second time they did it free of charge, it should have been free of charge my ticket was 157, it bacame 300+. seats dont recline. tough for your back."
Pros: "The initial ticket price. I was just needing a cheap flight to SLC from Houston to pick up my family and drive them back home. So for the price I didn't need any luggage and it was perfect and cheap."
Cons: "The lay over. The cost for a 12 oz can of soda is two dollars. The rude staff. The fact that my flight should of got there at 11:45 and instead it got there at 2:00 am."
Cons: "Extra charge for carry on bag"
Pros: "It was cheap and the pilot very skillfully navigated us around any turbulence"
Cons: "It's cramped and there isn't even water. When you add the expense of a bag and a drink, it usually is more expensive than other carriers that don't charge for these things."
Pros: "On time friendly crew great price"
Cons: "No recline on seats poor room for legs"
Pros: "The crew was nice."
Cons: "The airline charges for carry-on bag!"
Pros: "How attentive the crew was. They took time to explain the Frontier app in great detail and answered all my questions."
Cons: "That you had to pay for one piece of luggage. I can see paying for two but not one.The rates are great but it was made up for in luggage charge and price of snacks and soda."
Cons: "The seats are barely glorified lawn chairs, and the crew was extremely insensitive to the fact that the flight took off over 5 hours late and while most people were trying to sleep, they were loud, kept the lights on and were uapologetic that the flight was so ridiculously late. There were children and infants on that flight with exhausted parents who had to take off at 2am instead of 8:50pm. It was awful. Plus you have to pay for a carry on? Ridiculous. I never want to fly Frontier again."
Pros: "On time"
Pros: "Nice staff, just oblivious to everyone sleeping at 2am while they carried on and on with their chatty gossip."
Cons: "Baggage took almost an hour to arrive on both legs of my trip. We were delayed in SFO but due to a long planned maintenance there. Airline could have prepared better. No early boarding with my two year old, but only after all the elite and a whole zone 1 of people. Seats have big gaps that allow things to fall and people sneezing on you from behind. Loud crew with obnoxious lights on during a very delayed flight that became a red eye. Why pay more for seats near the loud crew who doesn't take in the fact that we're all tired. You want to sell food? Choose better items. My $3.99 coffee could at least have more than a powder non-dairy creamer. Flight price is so deceiving when you charge for everything on top of it, including where I sit. Lame, awful, corporate money grubbing mentality. I'll stick with southwest (I later learned they had had fewer options for once because they actually considered that a runway was closed)."
Pros: "Flight was on time"
Cons: "Seats don't recline and are very uncomfortable."
Pros: "Staff was very friendly and efficient."
Cons: "Food options were awful, especially for what they charge for food."
Pros: "Not trying to be hurtful, but not much. The people sitting next to me were nice. The temperature was fine. Nice takeoff, flight, and landing. The seating in the terminal was comfortable."
Cons: "The boarding was completely disorganized. The crew unprofessional. I overheard one crew member say to another "What is it with these Denver weirdos?". Then they complained about work and passengers the rest of the trip. I was in the front row and they must've assumed I couldn't hear them. I could. I know you're trying to reduce fares and making it an more a la cart experience, but $2.99 for a can of soda? Having to avoid the pile of ice that was dumped by the flight crew into the bathroom sink when i washed my hands wasn't very pleasant. The chairs are still incredibly uncomfortable, even in my "stretch" seating assignment ($35 poorly spent on my part). This trip made me rethink the cost benefit of taking Frontier. Flying United or American may be worth the extra money. And that's coming from someone on a tight budget. I used to enjoy flying Frontier and love taking a plane in general. I surely didn't this time."
Pros: "Absolutely nothing the flight never took off and I never mad it to my destination."
Cons: "Everything this is the worst flying experience I've ever had in my entire life I will never fly frontier again"
Pros: "Flight attendants were nice."
Cons: "Flight was late, Boarding procedure was not efficient it would help if they seated by seat letter when I boarded I was in seat f by the window but the other two seats were already occupied and they had to get up to let me in this happened numerous times for everyone on the plan causing a long boarding time. Plane had some off issues I think with the fuel pumps or the hydraulics there was a really annoying sound for the entire flight. No wifi Not enough leg room"
Pros: "The cabin crew were friendly and helpful."
Cons: "Fee for carry on bag. Fee to choose seat. Total fees doubled base rate ($200 to $400). Only most expensive seats recline. Did not participate in TSA Pre-check (they started a couple days before my flight but the website was not updated to tell you this nor to let you enter your KTN. If you read the website it would tell you they did not participate. If you call a live person can add your KTN to your reservation."
Pros: "Original price, before the nickel and diming begins."
Cons: "Nickel and diming us on every single thing. Inability to use the tray table for anything more than a cup of water (that must be paid for). Charging for a carry on."
Pros: "The crew and neatness"
Cons: "Entertainment"
Pros: "Liked that it was cheap and that it got me to my destination."
Cons: "The flight was significantly late (both of my Frontier flights were), the seats had no padding, the tray-tables were half-sized so that you couldn't put a laptop on them. I would not recommend Frontier to anyone unless they absolutely cannot afford another airline. There are affordable airlines that do cheap flights well. This is not one of them."
Pros: "flights were on time, gates close together. They had IPA beer for sale."
Cons: "seating was the most cramped I've ever experienced. I needed to get a boarding pass at the airport and low and behold all three of their machines were down. That was a 15 minute wait, compared to the normal airlines with 15 machines it was completely avoidable. I was surprised to learn carry on bags cost $40-45, putting me $20 below the cost of a untied flight."
Pros: "The crew was nice and did a great job."
Cons: "We were delayed on both flights by over an hour. The flight from Denver to Houston was delayed 2 and a half hours and I didn't feel we were adequately informed about when we would finally be taking off. Once we boarded the plane, we were delayed an extra half hour waiting on paperwork. All around it was a frustrating experience."
Pros: "Flight crew was nice"
Cons: "~3 hour delay caused us to miss connecting flight and almost miss 2nd option of connecting flight"
Pros: "Nothing!"
Cons: "My flight was cancelled."
Pros: "Price"
Cons: "Additional fee for many things and I had to pay multiple time for each fee"
Pros: "Crew were friendly"
Cons: "Airport gave wrong information, display showed gate A30 instead of the correct A11, mistake cannot just be attributed to airport but also to the airline for miscommunicating with the airport. Chairs were uncomfortable. But it was a cheap flight so understandable."
Pros: "Getting off the plane"
Cons: "- Seats are uncomfortable - My seat was dirty even after we waited for the plane to be cleaned - Seats can't recline - Tray table is a joke. Barely big enough to hold an iPhone - They charge you to pick a seat. If you want aisle or middle be prepared to pay. - They charge to bring bags on board - They charge for food - They charge for drinks, even soda or juice - They pretty much charge for everything - I will do everything I can to avoid this airline in the future"
Cons: "The carry-on fee was a surprise. Although I can understand the need to restrict what is carried on because people try to avoid check baggage fee, but a carry on fee is ridiculous."
Pros: "Not much to like about being late, choppy air and a terrible flight crew"
Cons: "It was a surprise to me that now even carry on luggage is charged. Please make that clear up front -- before purchase"
Pros: "We arrived safely."
Cons: "Seats uncomfortable. check in terminals went down."
Pros: "The crew was exceptionally helpful on both segments."
Cons: "The seats were not comfy at all- no reclining whatsoever and had to prepay for every bag."
Pros: "It was cheap. Overhead compartments were quite roomy."
Cons: "It was probably the most uncomfortable flight I have ever had the misfortune of experiencing. The seats were like wooden benches and didn't recline. The tray is only half the size of the standard. I'm pretty sure it's going to take a few sessions with a chiropractor to fix the abuse to my spine."
Cons: "We were at the Houston airport almost 3 hours before flight time, but no one was at the ticket counter. 45 minutes later the ticket agent arrived then told (not asked) us to move aside so they could check in passengers on an earlier flight. I completely understand the earlier flight thing, but common courtesy goes a long way! The gate agent was quite curt in his attempts to board people by boarding groups. The flight crew was tired, bored and just doing a job. Frontier will not be at the top of the list for future flights."
Pros: "The seating is extremely restrictive. The seats no longer recline. Seating arrangement is a charge item. Carry on bags are a charge item. In flight beverages and food items are charge items. The air in the planes is low quality."
Cons: "The stewards(ess) are bitchy because they are trying to manage very unhappy passengers. They constantly spout warnings to shut up, sit down and do exactly as they say or you will be taken off the airplane in irons by an air marshal. There is no comfort or piece of mind on a Frontier plane."
Cons: "The price of beverages/food."
Pros: "The crew on the way back from Denver were funny and kind and extremely helpful. The flight itself was fine."
Cons: "The prices for the trip. I wish I were explained that I would have so many different prices added on to the trip price. Carry-On price, seat price, Checked bag price (why are they different prices?). Only complimentary drink is water. The trip is more ideal for a weekend trip where all you need is a backpack that can fit under the seat. Then the pricing wouldn't be so bad."
Pros: "Tickets where excellent price since We did not check bags or carry ons. Airline was on time both ways and service was good."
Cons: "You have to pay for beverages but you can fix that buying those before boarding."
Cons: "The flight attendant complaining about it being a 9 hour day . Slouching Over seats seemed to be dreading the day."
