Pros: "Service"
Cons: "Seats and space"

Pros: "On time"
Cons: "Cold cabin"

Cons: "The tsa in chicago was very unorganized. The tsa workers were extremely rude."

Cons: "delay, then no sandwiches available for purchase onboard during a 3-hr evening flight"

Cons: "That all the passengers were rechecked at the Gate by TSA without offering any explanation as to why, if it was a domestic flight, why were they requiring ID again. And checking bags."

Pros: "On time smooth"

Pros: "The pilot was a riot, the flight was on time. Again, nothing wrong, nothing special. As it should be (if only we had more leg and seat room, and I am pretty streamline)."

Cons: "Rude staff, they changed our flight 2 times and did not offer a drink or food"

Pros: "Friendly staff. Landed early. Offered a free bag."
Cons: "They moved the flight earlier, which was not fun. And, there were no entertainment centers."

Pros: "Captain did his best to make up time"
Cons: "Flight was initially delayed an hour, then bumped to 30 minutes late."

Pros: "Nothing"
Cons: "Super old planes, no had a tv."

Pros: "I like that on American you still get a complimentary cup of coffee, a bag of pretzels, and a normal sized seat. I'm OK paying for that after trying some of the budget airlines!"
Cons: "Wish they had a gluten free snack, still that's really not a big deal at all!"

Pros: "Liked the little compartment above the tray for electronic devices and the outlet below helped keep my grandsons tablet charged for the flight! Liked the headrest - had flaps that folded out for support if you needed a nap."

Cons: "Will never fly American again"

Pros: "Puntuality"

Pros: "Crew was good."
Cons: "The television was in the aisle and couldn't be properly seen. Also there was no outlet charger. During boarding, even thou they called by group number, the crew allowed a queue in the front, making it confusing who was in line and who wasn't. Better wait till the end to board that get in that mess"

Pros: "Nice new seats"
Cons: "Crew came by once with drinks, never came back through with food/snacks. Never came through with water, as they usually do later in this flight. They spent most of the time chatting in the galley."

Pros: "Movies and on time departure and arrival"
Cons: "Crazy uncontrolled child in row across from us."

Cons: "There seets are two small. And they dont sell alcohol. That sucks."

Pros: "The crew was very apologetic"
Cons: "The fact that we were an hour and 45 minutes late leaving. I know they say weather was the cause and not their control, but every time...yes, every time I fly American there's a delay. Every time I've flown United I arrive early."

Cons: "The airline had trouble with the plane. After we waited 3 hrs in the plane they cancel the flight. They offer a hotel but it was very dirty"

Cons: "Delays and no communication on transfer options"

Pros: "Nothing. My fight from San Juan to Miami on Friday Oct. 7 was cancelled because of hurricane Matthews, since I didnot buy a roundtrip with AA they did not reimburse or offer me a credit for my returning flight. I contacted AA in two ocassions and both times their personnel were impersonal and even rude to me with the whole situation. I ended up losing $250 because of choosing American Airlines. I will do my best to avoid traveling with American ever again, and I will spread the word, as well. I felt robbed, so unfair."
Cons: "Everything"

Pros: "Friendly polite staff. Plane left and arrived on time."

Pros: "Great Workers, and Super nice staff."

Pros: "Taking off and landing."
Cons: "Boarding was slow. Seating was cramped."

Cons: "No have owned screen TV"

Pros: "Even when the plane was full they managed to help passengers to get seated."
Cons: "If you still flying economy class, why would you have to pay extra for exit row where the seats are the same. Only received pretzel and a cup of drink on a 3 hour flight once."

Pros: "Everything"
Cons: "Nothing"

Cons: "Turbulence was horrible That there is no internet"

Pros: "Comfortable seat"
Cons: "Lack of entertainment"

Cons: "One hour delay sitting inside the plane with no pilot!! And to top it off, the air conditioner was off!! Will never fly American ever again."

Cons: "The lady at baggage check-in was rude and persistent on not letting me board due to a slight fold in my passport. Other coworkers did not agree, and allowed me to proceed. She also spent 20 minutes in back searching for information while I waited and the line filled up. My luggage was also lost (the last to handle the luggage was this lady) and I needed to retrieve it 3 hours after my flight arrived."

Pros: "The plane actually left without a cancellation"
Cons: "Every flight on this trip was delayed"

Pros: "Staff was friendly"
Cons: "The seats were sooooooooo small and it felt like it was a really old plane, it shook a lot."

Pros: "Overall good flight"
Cons: "I did not like the time needed for boarding/ settling in. But that is a factor of people not following instructions. Not the crew."

Pros: "I really loved the process of boarding the flight. The flight attendants were very nice to all of the passengers including myself. The flight was really smooth where we left the airport on time and got to our destination early. The complimentary snacks were great as well."

Cons: "Terrible airport assistance, many unnecessary customs checks, uncomfortable seats, on flight bad service and late flight times."

Pros: "I was going home"
Cons: "Late flight no pilots andt broke my luggage."

Cons: "I didn't like the American airline people who checked my bag. She threw it because I told her nothing was breakable in it."

Cons: "Gg"

Pros: "Everything was on time, no delays."

Pros: "Should have individual tv's like jet blue does. There shoul be a family travel area for people travelin with todlers. better service and better food. Faster luggage pick up."
Cons: "Nothing. Expesive flights, an unprofessional flight attendant name Sarah, fighting with the customers. No entertainment. It was a nightmare"

Pros: "I live the service which make me feel good. Also the flight was very quiet and the crew help me in everything I asked."

Pros: "The great atendance and on time bording"
Cons: "There is no More options of free food included with the ticket fly and it was a longer flight and there wasn't no tv, no entertament"

Pros: "My window seat was all."
Cons: "I didn't get a call about the delay like other passengers, only an email at 7am as I was in line to check in for the 8:25am flight 395. The female crew members, a dark haired woman and a short blond haired woman both would have ignored me if the other two people seated by me did not also try to get their attention. The dark haired woman gave the guy next to me headphones and when I held out my hand she just looked at me and walked away as if she'd been called away. Which she hadn't she came back and started with the row immediately behind us and the guy next to me was nice enough to give me his. Also after nearly waiting 4 hours, 9 minutes before boarding we were given food vouchers and told to "run and hurry" and get food "to go" so most people didn't even bother using the vouchers because of that. I've had better flights with American Airlines, I just didn't know this one would be so poor. Definitely way below average expectations."

Cons: "After an 8hr flight from Madrid to JFk you dont need an 4.5hr delay on your connection flight."

Pros: "I was very pleased with the entire flight ."

Pros: "The flight was not full and was able to be moved to a window seat. The flight crew was very courteous."

Pros: "It was all pretty bad."
Cons: "The baggage policy wasn’t enforced at all, so I realized I could have saved $40 and had my backpack under my seat as my personal item since most others did. They charge for seltzer water. No internet options. Male flight attendant made inappropriate jokes and the rest of the staff was rude and blunt. Will not fly this airline again."

Pros: "On time, friendly"
Cons: "Seats a little hard"

Pros: "Inexpensive and convenient"

Pros: "The price is great, and the staff are great too."
Cons: "Delays (it is what it is) but people tell me they’re notorious for delays. Bartender at airport told me they’re shocked if no delays from them occur. Lol... refreshments are not complimentary but I expected that. Would I fly frontier again? I probably would. Great price, staff, and wasn’t bad spacing in the seats. If you’re a tall person, won’t be comfortable."

Pros: "Direct flight and price"
Cons: "Flight was delayed about 3 hours"

Pros: "I liked the punctuality of boarding and landing ."
Cons: "There was no air sickness bag in the seats and i had to ask one for my wife. But the crew gave me a thrash bag instead of a sickness bag."

Pros: "Cheap"
Cons: "Delayed 1 hr The tray top is so small and inconvenient that it is rendered useless"

Pros: "Direct flight"
Cons: "Seating is awful, like sitting on a brick NO RECLINE in economy seating and small. Avoid Airbus A321 planes whenever possible"

Pros: "Really helpful flight attendants"
Cons: "Very small (smaller than my kindle) tray tables. It was a very loud plane as well"

Pros: "Ahead of schedule"
Cons: "No drink service, no entertainment, very expensive. Never again"

Cons: "Flight was cancelled. Next flight two days later."

Pros: "I liked that I was able to select a seat."
Cons: "I did not like that I had to pay extra to select a seat, especially because the seat was not any more comfortable or spacious than the other seats on the plane. The staff rolled their eyes when customers requested service. I am never flying Frontier again."

Pros: "The price was cheap. Boarding was easy. Pilots were very nice."
Cons: "No entertainment. Have to pay for everything even just water which makes no sense. Crew did not want to be there and was not helpful. Took forever for people to get off much slower than other flights."

Cons: "Delayed by 3+ hours. Crew seemed disorganized at times."

Pros: "Landing !!!"
Cons: "I felt screwed all the way around! You charge for everything and provide nothing! The flight attendants were old and worn out looking and acted like any request was just a strain! I'll never fly with you again and have warned my friends also."

Pros: "Absolutely no issue with the flight. The boarding went very smoothly and the flight itself was flawless,. We even landed 15 minutes earlier than projected. Staff on the plane were efficient and pleasant. Pretty standard flight attendants doing what they do."
Cons: "The seating is another matter. They have moved the seats closer together so there is zero leg room and very close to the person next to you. Luckily I was in an aisle seat with a small child next to me so I had elbow room. The trays are ridiculous! Roughly the size of an ipad. Can barely hold a glass and a soda can. Forget about putting your laptop on it. The flights are cheap - but that is because you pay extra for everything. They charge for bags whether you carry on or check them and it's double the price at the gate if you don't pay at booking, charge for choosing your seat at booking, charge for all refreshments and food on the flight - only thing complimentary is a glass of water."

Cons: "Cheap! Need to pay for carry on??!! Will never use them again"

Pros: "Left exactly on time, boarding efficient and crew helpful getting bag stowed. The crew was one of the best ever."
Cons: "Really cramped seating. It is hard to sit in basically one position for more than two hours, and probably not very healthy."

Cons: "Having to pay for 2 carry on , made the reasonable fare not so reasonable. Paying for your seat is unacceptable."

Cons: "While the fare for Frontier was reasonable; I chose them because of flight schedule. However, I couldn't believe how much more I had to pay than just the fare. Baggage fees for not only checked bag but carry-on plus the seat selection added $94 EACH WAY to my costs. That is unforgiving. I'm back to Southwest."

Pros: "Cheap cheap cheap! Hopped a flight to Vegas round-trip for $200. Made sure my personal item fit under the seat and avoided carry on fee. I'll tough out the small uncomfortable seats for three hours to save a couple hundred bucks! Do the research and before you fly and won't be disappointed."
Cons: "Seat are small and uncomfortable. You have to pay for ANY snacks and beverages in flight. Bring a book or make sure you have a game or movie uploaded before you board. No in flight entertainment whatsoever. Heck they don't even have any literature in the seat back other than the safety checklist."

Pros: "Smooth flight"
Cons: "The seats were terribly uncomfortable!!! They had new thinner seats on my flight and you could feel little kids bumping or kicking your seat and every time they pulled down the little tray. The seats did not recline either. Very uncomfortable."

Pros: "We left on time and got in early."
Cons: "The seats are crazy narrow, you have to pay a lot extra to have any legroom at all, basically 18th century slave ship seating. Virtually all baggage is an up charge, even carry on, and they wouldn't even give you a bottle of water, that was like $2 or so. At the end of the day, a $105 ticket winds up costing $335"

Pros: "nothing"
Cons: "Seats don't recline, they are hard as a rock, they are narrow and absolutely uncomfortable. Will never fly Frontier again and will recommend that no one else flys Frontier either."

Pros: "The flight was on time, smooth, friendly staff."
Cons: "You have to pay for a carry on, which is more than a checked bag, no complimentary food or beverage. There isn't much leg room, even for a short person as myself."

Cons: "Seats were very uncomfortable"

Cons: "Before my flight I went on the Frontier website to find the dimensions listed for an acceptable carry on in an effort to avoid checking a bag and paying luggage fees. I purchased said acceptably sized carry on bag only to find upon checking in for my flight that I would be charged $45! I was also informed that selecting my seat would bring a charge as well. The "great deal" I was led to believe I'd found by flying this airline was simply untrue. When all was said and done, I could have flown more comfortably and for less money on another airline. Will never choose Frontier again."

Cons: "The stewardess announced baggage would be at 3, so we followed signs to baggage claim #3 and waited over 1/2 hour to find out she should have said TERMINAL 3. We had to take a bus to that terminal, ended up 2 hours behind schedule."

Pros: "It 's good and bad . For the good thing its fly on time. The bad thing its when the air plane going to lend it was too loud to made air hearts."

Pros: "Great crew"
Cons: "I paid extra for first class and it wasnt first class. Not worth the extra money."

Pros: "Once we got on the airplane (which we almost missed due to check in delays), the flight was fine. The inability to recline seats at least guaranteed me some room to use the tiny tray table."
Cons: "Nickel and dining at every turn of the road. Very slow, understaffed check in. Tray tables too small to use for any real purpose."

Cons: "The overall process of flying with frontier had much to be desired. I couldn't even get a glass of water on the flight. The boarding process was slower than slow and the gate crew and flight crew made that process worse. They kept telling us we were going to board and then we waited and waited and waited. Very unfriendly."

Pros: "That it wasn't overbooked or crowded. It was on time, actually a little early. Direct flight."
Cons: "To find out I had to pay for a seat selection and a carry on bag! Silly me I thought the price of a ticket included a seat. Overall round trip an extra $92.00!!! For real? Give me a break. Seats are uncomfortable, they didn't recline. I have flown Frontier before and it was not like this at all. Don't even get a complimentary beverage."

Pros: "Perfect landing in difficult winds"

Pros: "Got me to my destination on time."
Cons: "Really? I must pay for everything even water or coffee? Airbus seating was cramped, Tray tables were so small that my cut could not securely sit on it with small children bumping the seat in front of me. Riding on a bus is more comfortable. After 3 hours my back was sore from the stiff seats."

Pros: "Was good, seats lacked comfort, everything else was great, thanks!"

Pros: "Efficient flight and boarding."
Cons: "I didn't know how to rate food and entertainment since I didn't use those services. Why must the Frontier flights always be late? It was delayed both out to LasVegas and back to Milwaukee. Also, we were told that the flight to Milwaukee was delayed but it NEVER showed on the departures board nor was the time changed at the gate. These seem to be simple adjustments to make for all passengers to see that there was a change but it was never done and led to a lot of confusion."

Cons: "I did not know you all do not provide complimentary beverages and snacks. I did not know I had to purchase a seat to sit in for check in and only one carry-on was allowed."

Pros: "I got an e-mail stating that my flight was on time, only to get to the airport to find out that there is a two hour delay that they knew about all day.... Prices for checked bags AND carry-ons are ridiculous, then they try to make you pay extra for your seat...want food or drink? That will be extra too! Then there was a long wait to deboard and to get my suitcase, which came out at the wrong carrousel. I only thought I got a good price on airfare! First and last time flying Frontier!!"

Cons: "Flight was delayed two hours. Frontier did not give any notice via text, email, phone app that the flight was late. No comps given for poor service/late flight."

Cons: "It just sucks! Lost the bags for our flight and 3 other flights before than us"

Pros: "Price On time Good gate locations"
Cons: "Didn't know what would happen if I did' pay for my seat. Would I have a seat? This was the first time I flew with Frontier so I didn't know all the ins and outs."

Cons: "I was forced to gate check my mini skateboard, although it could easily and safely fit under my seat, and it wasn't there when I reached my final destination. While waiting at the gate check, the pilot informed me that it should be at the baggage claim. After waiting an hour for my checked bag, the skateboard never showed up. I spoke with baggage services and they tried calling the gate and no one would answer. I waited an extra hour and still no skateboard. Very poor service"

Cons: "I'm not a fan of when you purchase a ticket thinking you've paid the biggest expense and it shouldn't be too bad after that. Little was I aware I was going to be spending an additional 200$ just to pick a seat (so I could sit next to the person I purchased the ticket with), and check a bag (because carrying on was more expensive). I'd rather have the full up front cost than add it on when I don't have a choice."

Pros: "This was our first time flying Frontier and we were very pleased. The flight staff was very accommodating, outgoing, friendly, and funny. We will fly Frontier again."
Cons: "Flight attendants, price, smooth landing and takeoff"

Cons: "Paid extra for front row and it was not comfortable at all."

Cons: "There was a family with 3 young kids, Infant and a like 4 and 5 year old, complete brats with parents that were unable to control and they were loud and awful the entire flight. The flight crew did nothing, and I was grateful to be 2 rows away and not the people that were getting pounded by the kids feet. Not really Frontier's fault, but the crew could have tried to get the parents to do more. Having once 5 Daughters 8 and younger, more could have been done. Here's a hint: Even a slight effort saying something, to show you actually acknowledge the issue would have been some comfort to those of us around this family. Kids will often listen better to people other than parents."

Cons: "Delayed flight!!"

Cons: "No option for electronic boarding pass Must pay for seat selection Must pay for carry on luggage Must pay for refreshments Nickle and dime the customer on everything. Just make tickets more expensive and include those options instead of the current shady practice to mislead the customer into thinking the ticket is cheaper."

Pros: "Didnt have any food or entertainment on flight"
Cons: "Pricey airplane food."
