I booked thru JUSTFLY.com for DELTA AIR PARTNER = AIR FRANCE. AIR FRANCE was late to IAH, my departure airport. THIS CAUSED ME TO MISS ALL MY CONNECTIONS. AFTER 7 PHONE CALLS to BOTH DELTA AIR (who partners with AIR FRANCE) and to JUSTFLY.com my FLIGHT CHANGE and REFUND were DENIED. HINT: Don't use DELTA. Don't use JUSTFLY.com --Dan (OCT. 2022)

First flight on Delta and I was impressed. Tickets are a little more expensive. However, great entertainment and they even offer complimentary earbuds. I think their economy seats are slightly better than other planes. Thumbs up for me!

Take off and landing were ATROCIOUS.

Smoothest landing I've ever had! Delta flights are usually quality.

Plane (B757) was a little old, but loved the layout with bathroom up front for First.Class. Seats need updating, but overall very good .

On time to a t. The lead flight attendant Cameron was so kind helping us with luggage as we got on with our two little ones and then gave our son a treat as we headed off.

Very friendly and relaxed service

Arrived 20 minutes earlier,

The flight from Sydney to Adelaide was never ticketed and I was stranded in Sydney! Worst experience ever!

It was so smooth…it was so nice to hsve no issues flying. This was the first time in a while that everything was effortless Thank you

Good but delta needs to be more upbeat about the boarding process in Atlanta

There was a storm brewing in NYC but you would never know it from the flight. Great experience and barely any turbulence considering the storm.

Just a standard Delta flight: comfortable, excellent flight attendants. We had a direct flight, seated in Delta Comfort Plus, so it had a lot going for it, nevertheless, it was a good flight…

Pros: "Quick boarding"
Cons: "With flying there is nothing perfect all the time. I was able to sleep on the flight and had a place for my carry-on luggage. I wish unboarding was mad less complicated."
Cons: "Less announcements about masks we get it We don’t need instructions on hand washing Drink service needed"
Cons: "Better snacks"
Pros: "Competent crew"
Cons: "Too many people, especially children running up and down aisles during flight. Not adhering to COVID guidance. None of the crew addressed this ☹️"
Pros: "The crew was lovely and friendly, very pleasant to fly with."
Cons: "Not a fan that I was seated between 2 men I did not know which made me uncomfortable enough that I couldn't sleep at all during my red eye."
Cons: "Delta flies a lot of the CRJ planes, even on relatively longer trips. Traveling first class, the seats are a little wider than in coach and have a little more leg room, but calling it "first class" is a bit of an exaggeration. It's more like what coach used to be before the days of the flying sardine cans."
Cons: "Communicating take off time!!! It changed multiple times by one three hours and ended up flying the next day!"
Pros: "Very professional crew. Nice equipment. Very pleased."
Pros: "Pretty much everything"
Cons: "Food somewhat expensive..... boarding off the plane - people with no luggage should get off first then there should be some kind of control instead of everybody just getting in the aisles trying to get their luggage and holding everybody up"
Pros: "Good movie selection"
Cons: "Always late to depart. Seating was cramped and uncomfortable"
Pros: "Just the crew was super sweet and amazing. Everything else sucks. My seat won't recline and the flights get delayed all the time. Worst was the state LaGuardia is in right now."
Cons: "More on time performance would be great from Delta. Seats that actually recline and not get stuck. Screens in all the seats to enjoy entertainment."
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."
Pros: "The flight crew was friendly and communicated well. They also had a friendly attitude."
Cons: "A 1 hour wait for wheelchair assistance in Houston and then a 30 minute delay for wheelchair people to take my mom to baggage claim. Then the wheelchair attendant kept complaining she wouldn't receive a good tip to take us to the Lyft pickup area."
Cons: "The flight had over six hours in combined delays!!!"
Pros: "New plane, video in every seat"
Cons: "Organizing boarding better. Confusion in rules."
Pros: "Being that I needed to book last minute due to my other carrier only having one flight headed back to my destination, of which they weren't even sure if it would be taking off...Delta came through in a pinch. It was my first time flying with them but the ticket agent was helpful and attentive"
Cons: "N/A"
Pros: "The crew was amazing had no problems!"
Cons: "Nothing had a great experience!"
Pros: "Everyone was very courteous, the plane took off on schedule and arrived at our destination early. Also got a complimentary upgrade to Comfort Plus."
Cons: "Ticket price was a bit much, the seats and aisle inside the plane are only made for skinny people. Aisle was barely longer across than my foot, and the guy next to me was a bit bigger than average, leaving me to have to scrunch in my seat the whole flight. Lots of elbows, butts and hips knocking into my shoulders as people boarded."
Pros: "The staff & crew were friendly. I liked having access to free entertainment. I liked being able to see the tracking of my checked bag (notifications)."
Pros: "The flight was probably only half booked, the crew was awesome, very attentive and accommodating. Legroom at seat 13A was plenty. Also the fact that messaging is free is convenient."
Cons: "No food to purchase. The flight was over dinner time. Boarding - the ground staff’s announcements weren’t very intelligible."
Pros: "flight was on time..arrived early..friendly staff.."
Pros: "I liked the flight attendant in first class. Unfortunately I was not in first class"
Cons: "I did not like the attitude of the obese old man (I, too, am an obese old woman) as I saw it toward some of my cabin mates."
Cons: "Seats are hard to get comfortable in. Headrests are awkward"
Pros: "How they take off and land"
Cons: "The price versus other companies"
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: "Boarding"
Cons: "Nothing"
Cons: "Very uncomfortable flight. Seats are to close to each other"
Cons: "Weather delay"
Pros: "N/a"
Cons: "Delta costumer service was terrible. Cancelled my trip twice. They lied to us saying that they were going to give vouchers for hotel, that we were going to be automatically booked for next flight and that our bags would arrive with our flight. Waited 7hs to talk to an agent in the airport. 24h wait in Atlanta had to sleep in airport. They wanted me to wait three days in atlanta. They forced me to check a carry on because they didn't have room in the plane. They told me my bag would arrive with my flight. It never did. I still dont have by only bag. Unbelievable."
Pros: "gate personnel delivered bad news routinely"
Cons: "contingency planning was zero to get flight crews to next flight..."
Pros: "Boarding time and schedules were as expected or faster and good attention from the flight crew."
Cons: "Breakfast was mediocre for First Class."
Pros: "Flight was on time"
Cons: "I don't get it.. why airlines have no pride? Tickets are expensive! Fuel is lately cheap.. a Don't get it.. why do they keep crying and act like poor helpless companies? You are connecting 2 major cities in the US... can you please have some pride and offer a Nice airplane and not a crappy old one? Can you have some service going beyond just a soda? It doesn't make sense! When you fly in Europe with any major airline company (not low cost..), no matter how long or short the flight is, minimum you get a sandwich and abundance of drinks.. not with Delta (or any other american airline company).. pontless. We always get treated like cattle.. but they like keeping the prices of tickets expensive, don't they???"
Pros: "Good flight, comfortable"
Pros: "Some entertaining choices but not all clear which ones were in my flight"
Cons: "The food I wanted had sold out by the time I ordered it"
Pros: "Rebooked to Atlanta because of a delay."
Cons: "Delta notifications and Kayak notifications were giving me conflicting information, however once I arrived at the Houston airport a Delta representative clarified my issues."
Pros: "When we were landing!!!!"
Cons: "To crowded, seats to to!!! close need personal space not everyone baths!!##!!"
Pros: "There should atleast one checked luggage"
Cons: "Too expensive and baggage charge is additional which does not make any sense"

Nice

The person sitting next to me took my storage space under the seat but other than that was pretty good service and the food was not terrible.

Pros: "Landing"
Cons: "Everything. Major delay, lost my vacation time"
Cons: "The AC was off while we were waiting to takeoff so it never felt cool in the cabin for the hour(ish) long flight we had. I don’t know if it was the size of plane that made it so we couldn’t have that on while taxiing/waiting our turn to take off or what, but it was too hot and stuffy onboard in Texas on the tarmac. Our next flight from Dallas to Huntsville, AL had the AC on the entire time we were waiting our turn/taking off- the plane was newer and slightly bigger. Not sure what the deal was but it made the flight pretty miserable."
Cons: "No snacks"
Pros: "Efficient"
Pros: "Seats were comfortable didn’t have to pay extra for my personal day crew was polite"
Pros: "I was arriving only 45 minutes prior to departure time. Not able to check in my luggage. AA ticketing agent allowed me to bring my garment bag through security and to be checked in at the gate. Thank you very much!"
Cons: "Nothing really. Very satisfied customer here."
Cons: "If American Airlines didn’t delay 10 minutes so you miss your connecting flight twice within 1 trip"
Pros: "Very friendly crew, my flights were on time, good selection of movies. That's about it."
Cons: "Their Basic fare should be renamed "Bare-sic" – you have to pay for almost anything. Food choices can be better. I guess they can pay the Munich airport to get better treatment and not having to bus their passengers around."
Cons: "Size of seat"
Cons: "Smoke in cabin, has to return to Houston. Then they never transferred our luggage as promised."
Pros: "miserable. Flight."
Cons: "No concerns What I expected for a quick flight"
Pros: "Much better the typical American cattle class. Qantas actually served real food. Cabin was spacious."

Pros: "Punctuality"
Cons: "NA"

Cons: "Flight was delayed"
Pros: "Nothing"
Cons: "Our bags were lost going to Rome for a wedding and our cloths were in the bags for the brides father and sister bridesmade. No updates and the have my phone number and email address. You would think it was 1968 or something! Unacceptable in this day and age of communication! The wedding is in 48 hours and can’t find our bags? All this was explained to the airline in Rome the baggage handlers etc. etc. still nothing. Absolutely amazing and disappointing!"
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: "Everything was fine except..."
Cons: "The directions don’t work to connect to in flight entertainment."
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: "Airplane very uncomfortable!spacevery reduce to obtain more seating capacity they forgot customer comfort"

Cons: "I did not like the fact that American Airlines cancelled my 17 Yr old neice's flight from Dallas to Denver over a thing called "timed-out". And had her sleep in a room with a cott instead of a hotel room. And the fact that we as customers pay good money for tickets only to be subject to the airlines way of business. It is absolutely unacceptable!"
Pros: "The flight was excellent and the price was right"
Cons: "No complaints"
Pros: "New plane"
Cons: "Airplane temperature was freezing"
Cons: "Wifi only worked for a half hour, we paid extra to bring carry on bag, and the're was no space in the plane, had to send it in the cargo."

Cons: "Three hour delay"
Pros: "Crew was great. Plane was nice."
Cons: "No charger at seat."
Pros: "It was a good flight- friendly staff and crew."

Pros: "The seat was very comfortable"
Cons: "Wasn't expecting to have to run all the entertainment through my mobile device. I'd that's what you're gonna do, we're should get free wi-fi"
Pros: "The greeting and smiles I received from the crew members as I was boarding. The plane had entertainment and alcoholic beverages."

Cons: "I was so uncomfortable in my tiny seat. They are small and awful."
Cons: "Short flight, so no food or entertainment."
Pros: "Nice trip!"
Cons: "This was a connecting flight and they were at the opposite ends of airport so had to run to catch this flight!"
Cons: "Never made it and had to go yet to another desk because it was a united flight this was the worst i have ever experienced"
Cons: "The food options are poor at best and it's really sad that they don't offer anything for free. My ticket wasn't cheap so I can't imagine they're saving me money on my ticket by not offering better food on that long of a flight."
Pros: "Ordered the Protein Box, it was ok.. crew members nice."
Cons: "The Smell on the flight was unacceptable, I was sitting about a couple rows across the middle bathroom, and it smelled horrible, I had never had an experience like this on any other flight, I fly United many times a year, and this had me really uncomfortable for almost 5 hours, since the flight was delayed almost 1.5 hours while we sat onboard the aircraft at the gate, that had me miss dinner plans too in San Francisco as well. I really hope they can fix that, For the good of the passengers, felt like I was going to be nauseous all the time, and I'm really not someone that complains or takes time to review badly."
Pros: "Best united flight I've been on in a very long time!"
Cons: "Nothing"
Cons: "That the flight was delayed."
Cons: "Having to pay for entertainment."
Pros: "N/A"
Cons: "I didn't like the fact I was unable to reschedule my flight due to medical reasons. The ticket I purchased was nonrefundable. I wasn't asking for a refund, I was asking to reschedule due to medical reasons of which I have a letter from my Cardiologist as proof of my condition. I saw my Cardiologist Baxter D. Montgomery, M.D. phone: 713.599.1144 on June 9th and was treated for uncontrolled Blood Pressure. I was advised to reschedule my flight after a follow-up appointment on June 23rd. On June 10th I Called United to reschedule my June 11th flight and was referred to Lowestfare.com at 800.678.0998. I spoke to Albert and explained my situation and was told that I couldn't reschedule. I asked to speak to a manager and spoke to Jane who only confirmed that I couldn't reschedule and nothing could be done. Not allowing customers with verifiable medical excuses to reschedule their flight is a shameful business practice."
Pros: "Friendly staff. More leg room on United express"
Cons: "Snack options not good. Wi-Fi connection not good for United app and the free movies didn't work."
Pros: "Pilot communication was great"
Cons: "Gate and customer service agents are not helpful and not on the same page."
Cons: "Flight attendant was really not very nice at all. I felt like I was in trouble for even taking the flight. 'Move your feet. Bags have to be moved under seat. I need to see your seat belts.' She was curt, unfriendly & really made me upset with her bad attitude. Maybe she was having a bad day but I paid good hard earned money for my trip. I at least deserved courteousy & mutual respect."
Pros: "The flight attendant was one of the best ever - super sweet, funny, and accomodating. Also, the pilot nailed a super sweet landing at the end."
Cons: "Everything else. The only redeeming feature of the flight experience was the great flight attendant onboard and the fact that we actually landed at my destination. The coffee maker onboard had been broken for a long time and the airline couldn't be bothered to fix it. If I were the flight crew, I would have gone on strike. No leg (or arm) room on the express jet really punctuated a 34 hour itinerary with a sour note. I could barely walk off the plane in the end. Less comfortable than a cheap rental truck for the same amount of time. I likely won't fly again with United. I'd almost rather walk next time to be completely honest. At least it would be healthier!"
Pros: "I actually got bumped from this flight to one that went directly to my final destination of San Fransisco. What a great experience!"
Cons: "I payed for my flight about a month prior and for some reason still did not have a guaranteed seat on the flight and almost got left behind"
Pros: "Nothing"
Cons: "They only had enough to food for the front of the plane , me and everyone in back was left hungry, I have never been so disrespected"
Pros: "It was awesome, I could travel on Gold gropu for a chrap pice! Simply great"
Cons: "Flight got cancelled after being delayed for over 2 hours for mechanical issues. Gate agent was not overwhelmingly helpful or understanding to people's frustrations during the delay and didn't go out of her way to try to help. Customer Service was helpful and able to rebook and provide overnight hotel accommodations, but it was a very slow process that clearly frustrated some customers even more. Clearly not anyone's fault, but still frustrating and not a great flying experience."
Cons: "I cannot boo up to wifi so was unable to enjoy any entertainment."
Pros: "guess that the only thing I liked is that there was no problem during the flight."
Cons: "When we landed un Houston it took forever to get off the plane. It was unclear where to get my luggage. I had to leave it to pass through TSA to run and try to catch my flight from Houston to Chicago. When I arrived at my gate I got there just in time because they were starting to board the plane. I was uconfortable sitting between two men. I traveled alone. When we landed in Chicago, took forever to get to the gate so we can get off the plane. There was no entertainment, at least for me. My phone was way low in battery and ai couldn't watch anything."
Pros: "Easy flight , no fuss no muss . Great snacks ."
Cons: "More seating area in the airport near the gate , flight itself was great ."
Pros: "The only thing I have to say that is positive is that it was relatively easy to change my flight date and time in the United app once my original flight had been cancelled. The app was the only thing that helped me understand what was going on during the constant time and gait changes throughout the day."
Cons: "This airline is terrible. First we were told that the flight would be delayed 1 hour and 40 minutes. We were supposed to leave at 2139 from IAH to PHX. They changed the departure to 2309 due to "mechanical failure" of one of the aircrafts. We were told a plane was coming and that we were just waiting for another flight to Albuquerque that was delayed before us to leave the gait. Long after that first delayed flight left passengers for PHX were delayed 3 more times which ended in the final tenative departure time being 0145. We were told at 0115 to sit tight and wait because the plane was now here but the crew was still in route. Shortly after this promise, the crew showed up and everything seemed to be ready for us to board. Another 30 minutes went by and they announced that the flight was cancelled. United airlines had used up over 4 hours of changing gaits and times only to end up cancelling the entire flight. They did not offer any explanation for this nor were they the least sympathetic to the travelers who have all paid to be on that flight. The customer service was disgraceful and did not offer any type of help on reimbursement, hotel, cabs, or compensation for this."
Pros: "It was good to be in Houston for a brief moment!!"
Pros: "Crew were awesome, helpful when filling out documents for customs. it was nice to be on a less crowded plane for once."
Cons: "The plane advertized itself as having wifi, which didn't work once airborne. Why offer it if it doesn't work? Also, the plane looked like it was in rough shape, not very reassuring."
Pros: "nothing"
Cons: "The service was good, and the food tasty, but not very much. Also, the guy next to me couldn't sit still, but that is not the fault of the airline."
Pros: "Again friendly"
Cons: "Rough flight and technical problems then had to wait another 45 mins on runway to get to the door"
Cons: "The KAYAK APP sucks i selected annother date And time And missed the flight as a no show. I selected the date for next thursday And the APP moved it And booked it for the same day. impossible to take it was Erich And not the date i wanted. I reeboked it in UNITED direct payed 75 USD and fixed kayak mistake. Never use this sh...t again"
Pros: "When I arrived in Ontario my bags were there."
Cons: "The plan to San Fran was packed. I had the window seat in the last row. It was terrible. From SanFran to Ontario the flight was a very small plan and the stewardess was not very helpful. Just doing her job."
Pros: "Flight not full so with empty seat beside me I had lots of room to sprawl!"
Cons: "I still think it's wrong for airlines to charge for food so I didn't buy any. Couldn't get United app to work so no in-flight entertainment except what I brought."
Cons: "The only thing I didn't care for is I sat beside a man that was 63 and weighed about 275 pounds and I had absolutely no room to sit. Also I couldn't buy any snacks on the plane because it only took cards ."
Pros: "The schedule was timely"
Cons: "Am 6.4 ft my leg did not fit in the chair"
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: "a bit better, the flight was only half full so it made the experience more enjoyable overall."
Cons: "Kinda annoying they are always trying to upsell."
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: "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: "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."
Pros: "Evetything went smoothly; the staff were all very kind and helpful and there were no problems being kicked outta my seat, like United, haha!"
Cons: "I never appreciate having an extra Bill for both a carry on and a checked bag- I wish it all would be one lump summary so the process didn't drag out and my pleasure in finding a good priced seat wouldn't be dashed by tacking on $55 extra in luggage."
Pros: "On time"
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: "It is so annoying that frontier is constantly trying to sell you something. Other airlines sell things drinks or food but they are discreet. It's like frontier staff are working in commission."
Pros: "N/A"
Cons: "Never left! After 5 hours of delays, flight was canceled & 3 says later I still have yet to get by luggage returned FROM A FLIGHT THAT NEVER LEFT THE AIRPORT"
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: "Sat on tarmac 19 minutes before able to pull into gate in Denver. Unacceptable. Baggage fees are ridiculously expensive. Will NEVER fly this carrier again."
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: "cheapest fare I could find for last minute weekend trip to Las Vegas"
Cons: "seats dont recline. very uncomfortable. no entertainment. extra charge for carry on (you will charge me to carry my own bag?) I am not checking it in. flight was delayed (last flight out of houston)"
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"
Pros: "Not much to like about being late, choppy air and a terrible flight crew"
Pros: "I like the on-time flight and professional pilot and crew."
Cons: "I didn't like that the airplanes did not have reclining seats in coach section. I also was surprised to get luggage charges in both directions."
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: "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."
