Cons: "Not delayed"

Pros: "Airplane accelerated from stand-by directly to runway without preparation stop. Awesome!"

Cons: "The unfortunate delay prevented me from attending my grandmother’s wake. Fewer delays would be helpful."

Pros: "Crew was friendly"
Cons: "The boarding process was rough and haphazard"

Pros: "The crew did their best to deal with delay."
Cons: "There was an absolutely awful job done by both Delta and Kayak of informing us if additional delays, new gate assignments, when the plane would be reboarded. Also, people were quite angry that the plane had to be cleaned between the time we got off and the time we reboarded. Just get us home."

Cons: "No sandwiches for sale just snack boxes"

Pros: "Taco"
Cons: "Taco"

Pros: "The fight was very professionally carried out."
Cons: "The gate agent hurried ineffectively to board our slightly delayed flight (around 10 min). She left open the Priority Lane and boarded all pax there, having to step 4 steps to the left to scan every boarding pass."

Pros: "It was ok"
Cons: "Seat the family together"

Pros: "The crew and the comfort plus seat"

Cons: "Announcements were too loud in earphones (could damage ear drums) and entertainment was turned off while waiting 30 min for the gate to open."

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."

Cons: "Taxied at ORD for 45 minutes waiting for a gate to vacate."

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: "Nothing."
Cons: "Flight was delayed 2 hours. Even though I had carry on, they checked it and this made me waste my time at baggage claim rather than gate checking. Flight attendants were miserable. Power supply didn’t work at seats."

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: "Delayed"

Pros: "Ease of flight"
Cons: "N/A"

Pros: "Accident on way to airport, so I showed up to check bags 45 minutes before flight time. They said they couldn't get the bag to the plane..in 45 minutes? So, they put on the next flight... 6 hours later. Said I could fly without the bag... uh, no thanks. They would not look for alternatives without charging me more. Flight attendants were crabby, otherwise everything was fine. I flew British Airways a few months ago. Night and day. Seriously. Delta does not even approach having good service. There was no comparison to British Air--- Delta is not in the same league."

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

Pros: "Airline stewards were very friendly and pleasant."
Cons: "We booked with Delta, but were put on Air France. Even though we had our boarding passes in hand we had to wait in long, slow line for baggage tags because they would not print from kiosk. There was minimal Air France staff on duty serving thousands of passengers during busy season (July). While the lines grew larger, the staff was reduced from 4 to 2. Another long, slow line for customs, another long slow line for security=Charles De Gaulle airport was awful. We arrived at the airport 4 hours before our departure time and got to our boarding gate with no time to spare."

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: "Very uncomfortable, seats did not recline and seats way too close together."

Pros: "Entertainment options weren't bad. Most of the crew was polite other than one flight attendant who seemed ambivalent and unhappy to be there."
Cons: "Three hour+ flight and just one tiny bag of pretzels? And no lemon or lime wedges on the beverage cart? Plus, I have to pay extra for one checked bag. I will only fly Delta if I have to in the future. Subpar airline."

Pros: "Spacious, clean, great host and hostesses. The flight arrived at our destination 30 minutes early."
Cons: "Nothing."

Pros: "Newer plane! Comfortable"
Cons: "Nothing just great"

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

Pros: "What I liked: Sky Priority privilege came with separate luggage check-in queues and early boarding"
Cons: "What I disliked: Seats were too small No beverages or snacks offered No USB or power outlets available Three different groups board before Delta Comfort (e.g. those needing more time, travelers with children, first/business class) Didn't see the value compared to a less expensive main cabin ticket"

Pros: "I was notified about the delay via text before I left for the airport, which was nice. I would not have checked my email."
Cons: "Delayed for over 2 hours. I have never flown Delta before this flight and it wasn't a great representation. The flight attendants were nice but I was in a seat near the engine and it was making really weird noises. I fly almost every two weeks, so I'm used to engine noises but this was one of the loudest/most rickety sounding flights I have ever been on.. and I have flown Spirit a few times. It just didn't feel safe. Landing scared me a little too as I have landed in O'Hare countless times and have never flown so low to the highway upon entry. It felt like we were only a couple hundred feet above the cars."

Pros: "Great short trip with an attentive crew."
Cons: "Seats were a bit uncofortable and small compared to previous flights."

Cons: "Unnecessary flight cancellation. I had friends taking the same flight at the same time at the same airport from different airlines and they came through for their customers. I received no consolation it assistance with overnight accommodations."

Cons: "The flight attendant looked like she was mad throughout the whole flight"

Cons: "turbulance"

Pros: "We were delayed due to weather and Delta brought a cart of snacks and drinks over to the gate for us."

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"

Pros: "Everything went well"
Cons: "I was late from first flight"

Pros: "First time flying DELTA and to New York City. Really liked flying into Marine Terminal for it's smallness and easiness to collect luggage and catch a taxi."

Pros: "great crew!"

Pros: "It was great and very roomy I felt like a movie STAR!!!"
Cons: "N.A"

Pros: "The crew members were all professional and friendly."

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: "Great entertanment system and nice complimentary drinks including liqour."
Cons: "Seats a little cramped in coach"

Pros: "Best landing I’ve experienced recently!"

Pros: "the Bowing 787 was wonderful"
Cons: "flight had been delay and delay. we are very disappoint because we always think we are fly with British airway, we even went to check in counter of British airway but find out America airline are the solo airline.you guys can't advertized like that."

Pros: "The flight was great. Lots of movies to choose from. Food was pretty good too."
Cons: "They moved our flight around multiple times. We first had a layover in Chicago then through multiple emails and one phone call they just flew us straight to London with no layover. It all worked out it was just stressful not knowing exactly when we were flying out and if we were going to make our connecting flights. It did work out and we did make it."

Pros: "I made it"
Cons: "I had to run for all its worth."

Pros: "Smootm and in early."
Cons: "Not knowing no gratis drinks were served."

Cons: "Flight was cancelled with no compensation"

Cons: "Flight delays and cancellations."

Pros: "I got there on time and they didn't lose my luggage."
Cons: "The planes are too cramped, costs are too high, staff just love pointing out a carry on isn't a carry on even though it's sold as one and fits in every other airline's definition of one. Boarding process is ridiculous."

Cons: "Legroom was a bit cramped for a tall person"

Cons: "Bought 2 tickets but seats weren’t together poor service"

Cons: "charged a surprise of $175 for my third bag although Kayak mentioned i should be charged $75 at the time of booking. AA says it is due to Jordanyan Airlines, why was I surprised by this extra charge?!"

Pros: "We got to our destination safely, and American provided us with extra legroom seats."
Cons: "Service was curt and there was only phone-based entertainment."

Pros: "Should have booked AA instead of BA."
Cons: "AA couldn't find BA reservation. poor integration of services"

Pros: "Flight was on-time and crew was pleasant. This flight had movies available to watch!"

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!"

Pros: "Great service."

Pros: "Fast reliable two thumbs up!!!"

Pros: "One cabin crew went the extra mile for me...rescued a partial dental plate which I had inadvertently tossed in the trash."

Pros: "Good and entertainment"
Cons: "I have short legs so the long flight was uncomfortable. A stop of some sort would helpnif offered"

Pros: "The helpful steward"
Cons: "The bumpy ride"

Pros: "excellent flight. on time and no issues"

Pros: "Nothing!"
Cons: "Although an email was received 3 hours before departure that everything was on schedule, we were told when checking in our whole itinerary had been changed to leave the next day. We had not been contacted and we missed our daughter’s professional basketball game in France. This was the reason we bought the tickets from Kayak to begin with. The cancellations were happening with British Airlines and they were not working with American Airlines to help us out to get to the game on time."

Pros: "Staff and Entertainment"
Cons: "Back row, but someone has to sit there :)"

Pros: "fairly comfortable, crew was helpful"
Cons: "Having to use my phone for entertainment, with no place to plug it in"

Cons: "A passenger caused a delay in security, and as I'm rushing for the gate, the agent closed the door and told me I couldn't board. She then marked me as a no-show, while she was standing right next front of her. I had to spend the next 4 hrs on the phone, trying to get my tickets sorted out. Then, upon arriving at Heathrow,... No luggage. They told me it was still in Chicago. Upon finally receiving my bags, I find them full of sawdust and sand, and several items damaged. I will NEVER fly American Airlines again, and I will highly recommend to my friends and family to avoid them like them plague. Horrible service! Nothing but a run-around and not once did the agents apologise, even after admitting that my problems on this journey were due to a mistake made by one of their agents."

Cons: "Flight connections time was not enough for mam with infant.we missed the flight should better set up that kind of big airport"

Pros: "To be fair. The flight is only 50 minutes. By th time you get a drink it's time to land. It is completely unfair to the staff to have to do that. A flight like that. Have a box with a snack and some coolers that have 5 different beverages. I wouldn't even sell booze. I person can hold out for a flight that shot to get one on the connection or in the terminal."
Cons: "It's always a cramped flight. Nothing to be done except use a bigger, more spacious plane. The good thing is it's the fastest way to get to Chicago from where I lived it would take 6hrs by car."

Pros: "Spacious seats"

Pros: "Mostly friendly staff and quick flight time."
Cons: "Only half the plane got snacks and drinks. Additionally, I was forced to check my bag, which is a pretty big deal because I was connecting to an international flight and was unable to retrieve my prescriptions in all the rush to check my bag."

Cons: "Delayed a total of four hous!"

Pros: "There was nothing too bad other than I wasn't able to check in online bc our first leg of the flight was operated by American Airlines. But there wasn't anything that really stood out that would make me want to fly them again other than it was the best price."

Pros: "The crew was very helpful at each stop even though they weren't responsible for the disasters."
Cons: "Initially we thought we were flying with British Airways. We then had to do some digging to realize it was all out of American Airlines. Then we couldn't get proper boarding passes and luggage tags until one of the crew members spent a significant amount of time untangling each leg of our trip so they were in the proper order. We got delayed by 4 hours in Chicago and missed our connection in Manchester. We had another 5 hour wait there. By the time we got to Dublin, our bags didn't also arrive. After almost 24 hours of travel, we arrived but without all of our stuff."

Pros: "Very friendly staff, on time, most of all very comfortable."
Cons: "The Oppurtunity that could improve is the boarding in plane to have passengers board in groups."

Pros: "They were absolutely fantastic on checking on me, food, service, flight in general. Would recommend to anyone!!!"

Pros: "Easy flight, friendly crew."
Cons: "Girl next to me being sick the whole time"

Pros: "I like the comfortable chairs and screen touch screen in the seat in front of me"

Pros: "JAL is customer oriented and it's always a pleasant experience. Unfortunately, though the return trip is also JAL, the cabin crew isn't."

Cons: "The flight was delayed for 2 hours and after seated in the AA plane for 2 hours, the flight was canceled because without pilot?! Changed to a UA plane but after seated in the UA plane 1 hour, the plane needed to be maintenanced. Had been changed to another UA plane. After three times into three planes, arrived Chicago at 3:30am without the checked baggage."

Pros: "Boarding was good, Good flight , good service , plane was small for the distance with limited space for movement ,"

Pros: "Comfort"
Cons: "Nothing at all"

Pros: "our original flight was cancel due to snow, and we were placed at a hotel and food vouchers were given as well"
Cons: "no head set were passed out making video entertainment useless"

Pros: "Almost half empty cabin made this a very pleasant flight!"
Cons: "Food on AA was mediocre as usual. Edamame salad was nice and fresh for a change. Desserts are now prepackaged wrapping similar to candy bar..."

Pros: "Nothing"
Cons: "That it got cancelled"

Pros: "It's a good flight but the crew in Mexico City is really bad"
Cons: "Good flight experience, but the front desk in Mexico they are really mean. I request to talk with the manager to give me solutions but the manager was the worst. The manager show lack of experience and he was unable to give me solutions. He give me more problems than good news."

Pros: "Flight was fine"

Pros: "Nothing"
Cons: "I had two hour for connecting flight on quatr airways but the flight from St. Louis left St. Louis at 335 pm instead of 2pm. When I got of flight in Dallas they were already paging me overhead as a last call for quatr airways."

Cons: "When I arrived at CMI no ticket was issued for my second leg, so I could not use the internal transit bus to at Terminal 5 at ORD ("for ticketed passengers only). I had to exit use the external train (which was delayed) and go through the very slow Terminal 5 security. Almost missed my ORD-LHR flight (arrived at the gate after the official closing time)"

Pros: "Everything was just fine. I liked having my own seat in my own row."
Cons: "Nothing."

Pros: "Very good no complaint at all"

Cons: "Not delayed every leg of this trip and extend the travel time from 16 hours to 30 hours!"

Pros: "Friendly service"
Cons: "Cramped seating in basic economy, the upgrade seating wasn’t much better"

Pros: "Very good service"

Pros: "Lots of leg room for a regional jet."
Cons: "AC was not very good. Very warm on flight."

Pros: "The boarding was quick due to the size of the plane/amount of people. The flight was short- less than 50 minutes."
Cons: "It was a 2x2 charter flight with very tight seating. There were some seating issues, and the attendant was a little rude about them to some customers."

Pros: "Quick boarding, departed on time, arrived early, good cabin communication"
Cons: "This is a very cramped commuter jet, just one flight attendant to serve entire plane, she came by once for drinks but not a second time"

Pros: "the fact that the flight arrived on time without delay and the gates were easy to locate."
Cons: "How on earth did my i arrived lagos and only one out of my two bags showed up, i have to extend my stay in lagos and hoping my bag will come the next day, i have to pay $100 extra just to extend my one night hotel booking to two nights."

Pros: "Crew was extremely friendly."
Cons: "Temperature was way too warm."

Pros: "Boarding and flight went smoothly and on time. Too short for food or entertainment"

Pros: "That I didn't have to walk to Fargo. I wasn't dragged off a plane."
Cons: "3 flights to Fargo were cancelled. I was told I would not get to Fargo until 32 hours after my original time I was suppose to land in Fargo. After spending a fair amount of time on the phone with customer service I was able to get me on a Flight to Minneapolis that did not arrive till 1:30am then had to take a rental car to drive 3.5 hours to make it to my destination. I was not compensated for any of this. My return flight from Fargo to St. Louis was also Delayed. Both from Fargo and from Chicago. I have never experienced such poor scheduling from an airline or as many delays or cancelled flights in just a few day period."

Pros: "Seats felt roomy, in comparison to many other regional planes."
Cons: "Vinyl seats made my back really sweaty on a relatively short flight."

Pros: "Nothing"
Cons: "No meal on business, no free internet, no entertainment"

Pros: "For the most part the ride was nice."
Cons: "Seats were so small"

Pros: "Because of a 10 minute fix, we had to wait an additional 40 minutes for paperwork. I missed my connecting flight because of this."

Pros: "Legroom was a bit tight."

Pros: "The service was prompt and professional. The plane on this trip was clean and in good repair. The snack was simple and tasty. It was a pleasure flying United."
Cons: "The first flight from St. Louis to Chicago was very small. While I don't have concerns about flying in a small plane, I can imagine those nervous about air travel would feel concerned with the size of the aircraft."

Pros: "The boarding process went smoothly and was on schedule."
Cons: "Overhead compartment filled up and it was hard funding space for my bag."

Cons: "Massive delays on both flights out of O'Hare... No leg room...."

Pros: "Everything was great on the flight- we even got a snack ( stroopwafel cookie reminiscent of when I lived in Amsterdam ) and a drink. I haven't flown united in a while and was pleasantly surprised."
Cons: "Nothing but my flights were short ( under 1 hours)"

Cons: "Completely missed meeting due to 6 changes made during flight - Ask for a refund of some sort and non was given - not even air-miles or ticket recognition. Customer service from United was almost non existent. Will not be flying with united ever again."

Pros: "Good"
Cons: "Good"

Pros: "Was able to get on an earlier flight"

Pros: "A everything was fine other than..."

Pros: "I did not like anything. Please people don't book through kayak. Scam website"
Cons: "Flight delayed. Stayed at airport for more than 2 hours. Baggage lost."

Cons: "It took almost 15 minutes to get my bag back that I had to gate check. We were not allowed to carry on."

Cons: "The plane never cooled to below 80 degrees"

Pros: "Price was lowest for that date and itinerary."
Cons: "Feels like United is second class compared to other carriers. I purchased this for my Morher-n-Law who rarely flies was traveling by herself. there were 7 gate changes 3 day of. I Was very concerned if she would make it."

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: "The seats didn't bend back to be comfortable. Only 1 inch!!! The back was restless"

Pros: "Newer plane,"

Cons: "Late out of Stl. Missed flight out of Chicago"

Pros: "Nice flight and on time."

Pros: "Friendly crew, easy boarding"
Cons: "Small uncomfortable seats"

Pros: "Your Crew!!!! From the lady who checked me in to the last flight attendant saying thank you for flying with us... you should really be proud of your staff!"

Cons: "Obnoxious crew, repeating the same instructions over and over. No food, no entertainment. Short flight though."

Pros: "Flights took off and landed on time."
Cons: "Flight home was moved an hour early when I checked in. Gate attendant offered me a $500 voucher for taking the next flight...and then ended up putting me on the early flight anyway and gate checking my luggage. I really wish I got both the voucher AND to hold onto my carry-on. And then, leg room on that flight was so bad. I am only 6ft tall and was squished in like a sardine."

Cons: "There was no air circulating on the plane the entire flight. The plane was over 90 degrees when we got on. Everyone on the flight asked for the air to be on and we were told it was. No air was coming out of the vents. Horrible flight."

Pros: "Excellent service."

Pros: "No delays."
Cons: "No complaints."

Pros: "The crew were professional"
Cons: "The worst thing is that they schedule a CRJ-70 on this flight. This would be tolerable if the obvious alternative was a turboprop, as if Montreal were a small town, like Flin Flon. But it is not; it is a large and important city, and it stinks that the demand is so low that airlines must use small aircraft on these routes. Is it because Canadian taxes are so high on airlines that fares in turn must be high and not stimulate demand? I can't think of any other reason connecting cities this size would be on crappy little aircraft rather than on at least an A320/737 family aircraft. The problem is that there is not enough room in the overhead bins to fit rollaboards, even small ones like mine. So they have to "gate check" the bag, which does not always reappear at the gate at the destination. Less bad than the choice of aircraft was the fact that after we pushed back, they couldn't get an engine started, so they cancelled the flight and reaccommodated us on a later flight."

Pros: "Economy Plus is OK and crew is fine."
Cons: "Food is absolutely atrocious on US airlines."

Pros: "Everything was great and the trip was on time perfect"

Cons: "I would like to see free movies added to the flight like American Airlines have."

Pros: "on time arrival"
Cons: "power outlets were present but not functional. A real pity as I counted on it for my long trip to keep my portable devices. Lounge in Chicago does not have many outlets either and the next plane to Brussels either. This prevented me to keep my devices up along my trip preventing to work or watch movie as I wanted."

Pros: "Checking in at ticket counter was easy, service was accomdating for mom w disability. Love the option abt free ck bag for carryon. Very happy with change of flight option when original lay over was canceled. Love the text message update"

Cons: "Flight attendant "China" - needs to be doing something else - she was not interested in her job."

Pros: "When we got to Chicago we didn't have a plane so we had to wait hours and then walked to another gate .. Wait for another hour and then they said we would not have anything to drink or eat in the flight"

Pros: "The attendant at the boarding counter was very helpful."
Cons: "As we are flying international and had a single itinerary, They didn't allow two checked in baggage's inspite of repeatedly explaining them that we have to take connecting flight which allows two checked in baggage's for each person."

Cons: "Our original flight got cancelled out of St Louis, not once did the service agent tell me I could rebook my connecting flights myself on my phone. When I found out, I successfully rebooked my partner's flight and my reservation disappeared. Because of this I was on standby (along with 87) other people while my partner had a ticket."

Cons: "Loudness And over priced EVERYTHING"

Pros: "new jet. enough leg room (i'm male, 5-10). Overhead bins are normal size (can hold typical carry on), not the microscopic ones. Everything was on time."
Cons: "STL ticket counter was only staffed 2 hours before the flight -- which makes sense if they didn't have more flights, but the signs weren't big and complete enough for passengers to realize what was going on and how we would check our luggage. So we were standing around a bit confused. Once Frontier people showed up, it was fine. Also, coming back to STL, I had a 2 hr shuttle bus ride that was leaving 30 minutes after arrival, and although the plane arrived on time, the luggage didn't reach me until 37 minutes after, so I had to get a hotel room for the night. I don't know how luggage handling works, so maybe not Frontier's fault at all. 30 minutes isn't much time, but it was a direct flight, so I thought it would work."

Pros: "Flight was on time. All but one crew member were pleasant and professional. Low cost initial fare, but..."
Cons: "Relatively short flight made absence of beverage and food/snack sufferable (without paying high end bar prices for for snack or drink). Paid for reasonable leg room, carry-ons and a checked bag. So, after all those fees, flight cost was average."

Pros: "Service was fast and friendly and very efficient!!"

Cons: "Everything was fine other than how cold it was on the plane. The coldness actually woke me up several times because it was so bad."

Pros: "Very nice flight and crew. The gave me priority seat and boarding because I'm military as well as 2 free carryons."
Cons: "Only thing to make it better would've been wifi"

Pros: "Friendly on time service"
Cons: "Baggage fees"

Cons: "When I got to the gate, I was told that I had to pay $45 for my carry on luggage, which I found it to be somewhat insulting (if I had agreed to check-in the luggage it would have been 'cheaper' only $40). This was the first time I had ever been asked to pay for my carry-on luggage, and the basis for me to never fly Frontier ever again. They claim that it was because of the ticket I purchased through a third party, and I told them that they should not advertise any tickets where you intend to charge people for their carry-on luggage. To make things worse, it appears that Frontier does not participate with the TSA pre-check program, and even though I had my global entry card with me, the officer at TSA pre-check would not allow me through this line because of the airline I was flying with - Never again!!! I suspect that on my way back I'll be forced to pay another $45 for my carry-on luggage, which I despise."

Cons: "Very uncomfortable seats, they did not recline. Crew kept talking loudly at the back and it was hard to sleep ."

Pros: "The low price of the fare"
Cons: "1. All the added charges even for a refreshment 2. The obnoxiously loud noises coming from the plane mechanics 3. A group of 5 that were drunk, belligerent, loud, and inappropriate 4. Lack of cleanliness (old tissues & trash stuffed in the seat pocket, trash on the floor, looked like throw up in our aisle-our entire aisle asked to move seats) 5. Stewardess speakerphone so loud It was painful"

Cons: "Had to pay for carry on and water. What a joke!! A unruly child was screaming and pounding on the back of my seat and there were open seats up front so I ask a attendant if I could move up. The attendant told me according to FFA regulations I needed to stay in my seat. I FOUND OUT LATER WHAT SHE TOLD ME IS TOTAL BS!!!!! Never again Frontier!!!!"

Pros: "The crew was professional."
Cons: "The seats are not comfortable so it makes it difficult to sleep. Ours was a red-eye so that was not good."

Cons: "You charge extra for everything."

Cons: "I arrived later than anticipated, flight was delayed and was late for a work meeting"

Pros: "The crew was better than expected."
Cons: "Have to pay to select a seat?? Carry on is $40. Checked is $35. No Skycap. I won't be flying Frontier in the future unless they decide to go to Southwest management school."

Pros: "Flight attendants and gate personnel were very gracious. Nice flight (weather cooperated) and no delays."
Cons: "Desk personnel at ORD were horrible, very abrupt, and just plain angry. Everyone has a bad day, but I'm easy to deal with and the only thing I did was step one foot over the "wait" line to the counter. I apologized after you snapped at me and continued to smile... while you continued to frown and be condescending. That alone means I don't fly your airline again. I can afford the extra for Delta and I should have stayed there. Seats were really uncomfortable and though we paid extra for the better seats, leg room was at a minimum. Again, about what I expected. All told, for 1 bag and a little more legroom, we paid an extra $115 per tick. Not really any savings over a more full-service airline."

Cons: "Uncomfortable chairs,"

Pros: "Cheap"
Cons: "EVERTYHING is an added on cost, no frills, cramped,"

Pros: "Flight left early, and arrived about 45 mins early, no problems on the flight, friendly staff, excellent price, very happy customer!"

Pros: "Smooth effective boarding to the plane."
Cons: "Seats were like the park bench, hard as rock. By the time we landed I had a sore back and neck. I don't think cabin was pressurized properly or there was something not right as my Airpop during landing was much more savior than I have even had and was very painful. his was first and will be last flight with them. Not worth the $30/$40 saving you make."

Pros: "Nice seats"
Cons: "It's silly to pay so much for a carry on, but the flight was so cheap."

Pros: "The worst flight I have ever had. Most uncomfortable seats I've ever sat in. I will never ever fly this airline again. They also charge for everything. Everything had a fee. Horrible experience. I guess AA is the best."

Cons: ""Upgraded" to the most uncomfortable seat I've ever flown in. Expensive checked and carry on. Flight attendants were all extremely rude and unprofessional - spent the entire flight ignoring the passengers and clustered at the front of the plane complaining about coworkers. The flight attendants were doing much of their work by flashlight - seemed very substandard. No welcome. No goodbyes. It was clear that they had disdain for the clients. No food or beverage service. Will never consider Frontier again."

Pros: "Flight left on time and arrived a little early. Staff always offering seatbelt status in a prompt manner, keeping our safety in mind."
Cons: "Hard to get any sleep in a cramped space, but that's how it usually is on a redeye."

Pros: "Boarding was quick"
Cons: "Messed up name on ticket had to call to have changed (would have been charged online to do so) Only saw flight attendant once This airline really nickel&dimes you. Tickets cheap but you pay for absolutely anything you may need. If you travel with absolutely nothing than this airline may be good for you. This is my second time with frontier had poor to okay experiences both times, will avoid this airline in the future."

Cons: "landing and waiting for a gate for 45 minutes. We were an on-time arrival without a gate? That is very poor planning and anticipation of flight needs."

Cons: "Paying for a carry on bag. It was very expensive. I will not fly frontier again."

Pros: "The crew treats you better than crews on more expensive airlines, and they have a great sense of humor. You can tell that positivity and how they interact with passengers is a priority in the hiring and training process. A lot of people have complained about having to pay extra for carry-ons and other luggage, but Frontier is REALLY clear about their policy for baggage when you book, so these people shouldn't have been shocked. It is a great deal for people who only travel with one small bag, and I'm glad that there is an airline that offers such cheap flights for light travelers. If you need to take a lot of luggage, you can add the cost as you are booking and then decide if it's the best deal before you finalize payment. Overall, it was a very good experience. You aren't going to get a ton of extras for free on this airline, but if getting to point B from point A with a nice flight crew is all that matters to you, Frontier is a great deal."

Pros: "The crew on my return flight was much more personable than on the flight out. Boarding and unboarding were super easy (no checked baggage for my flight)."
Cons: "THE HIDDEN FEES ARE CRAZY RIDICULOUS! Sure the flight starts out cheap, until you realize you have to pay for carry-on bags, and another fee when you pick your seat! Overall my flight cost was $130 more than anticipated with the hidden fees. The seats on the flight to my destination were old and uncomfortable and my seat did not recline (and I paid $30 for the super stretch seating)."

Cons: "Flight was delayed 3 hrs due to a mechanical problem"

Pros: "it was a direct flight. It was the only carrier with a direct flight. The plane arrived with no difficulty."
Cons: "The Frontier website was misleading. On check in it asked to pick a seat assignment, which were charged additional money for. I tried to undo the seat assignment (after I went and read their policy that it was optional.) So the website is fixed, that it can not be changed. So I called Frontier and after a 45 minute hold time was told options (seat assignment) can not be changed and I had to pay for it. This added $24 each way for a total of $48 additional charge. Also only a small carry on allowed. so that added an additional charge of $30. The seats don't recline even a little bit. as it was an Airbus and not a Boeing plane. not as comfortable as Boeing. Less padding in seat also."

Pros: "Nothing stood out to like."
Cons: "The flight attendent had a hard time explaining things over the loud speaker. To high on in cabin food."

Pros: "Easy boarding, knowledgeable staff...friendly service"

Pros: "Amazing service. Kat and Linda from MIA airport check in were phenomenal and completely made my trip in every way possible. I hope frontier recognizes how truly lucky they are to have these women on their payroll."

Pros: "Price"
Cons: "$1:99 soda realy"

Pros: "Overall good experience. Flight got in early but then had to wait for gate to clear."

Pros: "First of all they charge you 40$ in internet for your carry on bag ! You dont have food or snacks Its cheap only If you dont have any bags otherwise take an other airline !"

Cons: "Over 1.5 hr delay in Las Vegas- sometime cannot be helped, I understand."

Cons: "I spent the entire day in the airport b/c they strung us along 2 hours at time. Then when the plane was finally ready they had to get a new staff for the plane and delayed us another 4 hours. Couldn't they have planned ahead and found a staff before the plane was ready?!? Or if they had just told us upfront the repair was going to take 8-12 hours we could have made use of our day. Losing a whole day of productivity when you own a small business is catastrophic. Frontier really screwed me over."

Cons: "the seats"

Pros: "Nothing"
Cons: "Everything"

Pros: "nothing"
Cons: "poor accommodations of the disabled rude staff No ADA accessibility over priced "a-la-carte" style of upcharging"

Pros: "The crew was fine."
Cons: "They charge for everything, is a scam . I will never book a flight w them."

Pros: "Very disappointing - $45 to carry on a bag or $40 to check? Wish I would've paid the extra $100 to fly SW, Delta, United, ETC. The trays were 1/4 size of an iPad. You have to pay for a soda, water, or any beverage. The seats were small, uncomfortable, and didn't recline."

Pros: "Notification emails about delay and new departure time"
Cons: "- late departure - we spent 45 mins in plane after landing at Chicago airport and it was not fun - not a variety of food to buy options"

Pros: "Price early arrival"

Cons: "Apparently the seats are "pre-reclined". What a joke! My gf and I now call this Frontier Airplanes, because this can't be an airline."

Cons: "No snacks, not comfortable at all, overpriced, yhere wasn't a significant amount of savings because I paid to carry on my bag, no snacks and not comfortable!"

Pros: "The captain got us 30mins before time!!!"
Cons: "My 85 year old grandmother took this flight and she didn't get any assistance with her wheel chair .The crew wasn't very friendly.I will not ever flight on frontier again."

Cons: "Nothing."
