Pros: "Seats were great! No snackage... #covid19"
Cons: "Drinks"

Pros: "excellent service very happy with the crew"
Cons: "Better food"

Cons: "The plane was cold. The entertainment was mediocure. The staff was telling the people to get in their seats quickly as they had missed their scheduled time for take off. Yet, they 1st said we would board a little late because og clearing out the previous flight. And, no one could get carry-ons above their own seats and had to go back to then come forward. The attendants should monitor better what is brought onboard. I thought they were rude. And it took almost an hr to get our luggage at the carosel."

Cons: "Flight was so delayed that we missed our connection"

Pros: "At washing D.C. , soon I've get off the plane and ask to one of crews at gate 36.that lady didn't know what time is for next connecting flight for going to Columbus Ohio. She keep saying I don't know when ? What time to leave.why it's so late to connect next Flt. That answer doesn't give me a clue made me a frustrated. I do not use any more the connecting Flight in the future."

Pros: "Nothing"
Cons: "Be on time. Run planes that aren’t constantly breaking down."

Pros: "Great crew and staff."
Cons: "I didn’t notice that the aircraft didn’t have chargers so my phone died mid flight. I wish there were chargers on long flights."

Pros: "Pilot was awesome. Beautiful landing. Got us there safely."

Cons: "Rude crew member who yelled at me from across the cabin. I had stopped at an empty row to sit and look out a window. She yelled at me to return to my seat."

Pros: "Expensive, tight seats, They now charge extra if you want to sit by the window. Mediocre."
Cons: "They lost my luggage. Avoid this airline like the plague. Never again."

Pros: "Crew was full of older agitated staff. The black woman with curly hair was very nice, and friendly."

Pros: "Absolutely nothing!"

Pros: "Lots of leg room for such a small plane."
Cons: "AA did not update the flight status. My inbound flight was delayed due to weather but AA kept reporting the connecting flight as on time. I ended up making the connection with time to spare. If AA had reported the delayed departure I would have stopped for food. My bag did not make the connection."

Cons: "Waited one hour and 50 minutes for my luggage. The ENTIRE flight had to wait 1 hour and 50 minutes for our bags to come in on the carousel. There were no apologies or explanations or compensation offered for our wait. Absolutely unacceptable."

Pros: "Wonderful and on-time!"

Pros: "Comfortable seating and attentive service"
Cons: "Remote terminal which required walking stairs with carry-on bags, and two bus rides to reach the plane. No food other than packaged snacks in first class. No seatback video screen."

Pros: "Andres was so nice. Amazing actually"
Cons: "They boarded us then we had to switch planes. Delayed an hour"

Pros: "The same as in Amsterdam."
Cons: "well it was okay. Since i was happy to board my flight to miami in time."

Cons: "Uncomfortable plane"

Cons: "No one knew what was going on. We boarded late, then sat there for 40 minutes with no communication, then we had to de-plane. But they couldn't get the jet way to work, so it took forever."

Cons: "Flight was delayed 4+ hours due to weather. Gate agents did not communicate well, were rude and not helpful."

Pros: "Everything was on time"

Pros: "Non stop and an on time arrival after 20 min delay at phl when no gate agent could deplane previous flight. After being re-ticketed from overbooked united flight all in all not bad at all."
Cons: "They happen from time to time,... from many unassigned seats causing long gate line where several butted to the front to random noises during the flight from passengers to 6 bathroom trip guy just weird all around. Plus the multiple gate changes by PHL which are to be expected. Just a regular PHL departure,..."

Pros: "No problems, friendly crew"

Pros: "Professional crew. Good landing."
Cons: "Twice delayed because of delays in Newark connection. Need more room in coach."

Pros: "Comfortable aircraft with an efficient and present crew."
Cons: "First, passengers had to wait in the main terminal for a bus ride to a remote terminal to wait to board. The only food items offered in first class were unhealthful packaged snacks. On a flight such as this, at 8:12 am, something like a breakfast wrap would be more appropriate, especially considering the fare charged."

Pros: "Nothing spectacular when sitting in economy."
Cons: "Agent at lost baggage was less than desirable. His attempts to read my mind failed miserably."

Pros: "We boarded on time and we departed on time. We got into Chicago 30 minutes early. We recently acquired a AA credit card and we got 2 checked bags free and priority boarding (Group 5). In today's world your need priority boarding of some sort on AA or you risk not being able to store you bags in the overhead and may have to get it checked free to your final destination. Also, one of our checked bags had a painting in it that we purchased and the bag and painting arrived unharmed. Good job by AA baggage handlers."
Cons: "Cramped seating. Airlines seem to be moving seats closer together to be able to hold more passengers."

Pros: "Wider seats."
Cons: "N/A"

Cons: "Escape row seat in a non-escape row wasn’t too fun or comfy. Took half the flight to connect to the WiFi to watch movies to discover that the selection was limited and poor selections at that."

Pros: "Crew On time Boarding"
Cons: "Seat space very tight and I’m not a very big person Seat ahead of me fully reclined left me even less space Seats are very uncomfortable Expected more for the cost of over $200 one way"

Pros: "extremely friendly, smiling, and helpful service by the flight attendants, comfortable upgraded first class seat, timely arrival."
Cons: "No food service other than snack/ junk food."

Pros: "Nothing."
Cons: "First of all, the announcements that come on after we take off and last for 20 minutes is very annoying. We have brains, we can figure out how to plug our head phones in to watch the inflight entertainment. After saying the “show” was going to start, it never did. The screens were down the whole time and it remained black. good thing I had my phone with a movie on it, or I would be very bored for the 3 1/2 hour flight. Never flying with American Airlines again."

Pros: "Nothing"
Cons: "An S80? Really? This plane was older than me! Horrible plane! The crew looked like they had been up since 4 am. Looked exhausted and unfriendly. I do want to clarify that this was an American Airlines operated plane, not etihad."

Pros: "Flying beats driving"
Cons: "no entertainment or food."

Cons: "Trying to make any changes to the booking or check in was horrible. Because this was booked through kayak, then through an agent, then ultimately an Iberia booking on a British Airways / American flight, it took about 5 rounds of phonecalls being passed to another company or another department to get anything done. Sure the flight was cheap, but 6 hours of phone calls to get anything done is unacceptable. The plane used for this flight is ancient. Very tired seating, and no seatback entertainment. One children's film shown on the central TV screen followed by old sitcoms....For a transatlintic flight, this is really poor."

Pros: "The airplale MD 80 are old"

Pros: "The plane wasn't full so that was soo nice."
Cons: "No TV's or outlets."

Cons: "Seated next to two obese people and when combined with narrow seats made it all but impossible to sit comfortably on my seat. Flight was delayed on the tarmac for almost an hour due to missing part. When flight arrived in SLC, gate wasn't open (at nearly 1 AM) and had to wait on tarmac again for 10-15 minutes."

Pros: "Flight was good, there was no entertaiment, so i put one, but the flight was only almost 4 hrs. At night."
Cons: "I like the service I got and the service I got. I have back surgery and walk with assistance and the lady that helped me a the the birding desk took care of my needs and it was so much appriciated.. Thank you."

Pros: "Biscotti, pilot, crew"
Cons: "Seating is so uncomfortable, unable to recline more than an inch or so, then everybody rushes around making you return to an upright position! What's the point?"

Pros: "Upgraded to business class"
Cons: "I've never been so cold on a flight in my life. Had two blankets on me and still shivered the whole flight. Others in the cabin were wearing coats and sweaters - in July. Crazy cold."

Pros: "Was quick once we figured out what airline to check into."
Cons: "We arrived at the Finnair desk to find no one. Wasn't told to go to a American Airlines desk until standing in line for awhile. Could've miss s our flight due to this miscommunication. Also, could not check in online through Finnair, nor American. The whole process was very confusing."

Pros: "Was up to standard for everything. nothinf lacking, not exceptional"

Pros: "We flew out of Dallas on AA Eagle and what a great flight! Super roomy, great staff, newest aircraft. Loved it .. wish we could have flown all the way home to SLC on the Eagle!"
Cons: "The only thing we didn't like was the turbulance coming into Amarillo (tornado warning!) but the AA Eagle handled it just fine .. so truly there are NO complaints .. Love this short flight between Dallas and Amarillo!"

Pros: "The FAs on this flight were nice, engaging and caring, the way they should be, so I was happy about that."
Cons: "There was a teenager in front of me that was turning back every few seconds and made me nervous what she was looking back for. Then, there was an elderly woman sitting right next to me that kept pushing me every time she'd get out her tablet, pills, pocketbook, etc. By the end of the short 2-hour flight, I've had it with her."

Pros: "Great selection of movies, comfortable flight overall."
Cons: "Only one drink service for 5 hours, attendants not friendly or attentive, and it took an eternity--again with AA--for the bags to hit the carousel. Over 30 minutes' wait."

Pros: "Laura was very helpful and so was the gate agent."

Cons: "I dislike how early the entertainment system shuts off"

Pros: "Upon leaving Raleigh, N.C. Our plane was carrying a fallen soldier and a marine who accompanied him . They announced this and gave the other passengers the opportunity to walk to an area to watch the very solemn ceremony. It was all done with respect and handled timely. The flight still left as scheduled and arrived on time. Not that this was the most important part. Even if it had caused me to miss my connecting flight, the ceremony for the fallen hero was more important."

Pros: "love when they turn off the lights"
Cons: "annoying late notifications of gate changes"

Pros: "Efficient"
Cons: "Free wifi"

Pros: "Everything"
Cons: "Perfect"

Pros: "Getting a meal and drink"

Pros: "One attendant did it all. And very well. Impressive."
Cons: "More snack options."

Pros: "Everything from ticketing to deplaning was smooth and professional."
Cons: "No problems at all."

Pros: "On time"

Pros: "Having about an hour and 20 minutes left me with enough time to explore the airport from one gate to the other without feeling terribly rushed."
Cons: "The ONLY thing negative that I can say is that the Chicago airport had no charging stations at my gate."

Cons: "We had a particularly grumpy flight attendant that made the experience less enjoyable for many. Also, while it was a “Lufthansa” flight, it was really operated by United and did not offer the level of service or politeness that we experienced on our Lufthansa flight from Denver to Frankfurt."

Pros: "United and American Airlines are subpar at best. I had a poor experience with rude staff and the seats were VERY uncomfortable."
Cons: "United and American Airlines are subpar at best. I had a poor experience with rude staff and the seats were VERY uncomfortable. Definitely not worth the cost. Especially cause EVERY little thing costs way more. They don’t even offer free carryons. Lame."

Cons: "No bags to go to overhead bin"

Pros: "Not much"
Cons: "The food not fit for human consumption"

Pros: "Quick boarding. Ontime departure."
Cons: "Very small servings of food."

Pros: "The small plane, all seats were good seats"
Cons: "The guy that was farting on the plane"

Pros: "Dr usus I"
Cons: "The keys"

Cons: "I didn’t like being told I couldn’t use the restroom in front because it was for 1st class only. I was in a wheelchair and dealing with spine issues which made it very difficult to walk at all. Then on my flight home from GR the flight ended up being 3 hrs late. I was in terrible pain."

Pros: "Service was outstanding"

Cons: "no food, no entertainment, tiny squished seats"

Pros: "The gate person was rude gave me a boarding pass to somewhere else under someone else's name and then told me she couldn't help me."

Pros: "United payed for the room and 20 bucks for food."
Cons: "Late. Missed the connection to Gillette and had to stay overnight."

Pros: "We'll coordinated."

Cons: "See above comments."

Cons: "My seat doesn't recline, on top of being as comfortable as a rock. Passenger in front of my threw their garbage everywhere"

Pros: "punctuality, crew"
Cons: "seats on EMB175 are just not meant for flights longer than an hour. Absolutely no low back support on a firm seat flat as a 2x4 makes for a miserable experience, particularly after a previous intercontinental flight."

Pros: "Extra leg room, larger plane"

Pros: "The service was good"

Cons: "We got moved from United to American Airlines because United overbooked out first flight. We finally landed in SLC 8 hours later than we were supposed to only to be told that they had left out luggage in Chicago. It is now a week later and I still don't have my luggage! This has been the worst travel experience I have ever had!"

Pros: "Glad you didn't give priority to those with other designations like priority plus etc"

Cons: "Plane late leaving Chicago due to no pilot."

Pros: "Sat in the middle seat had never done that before,hopefully wont get to do it again. Did not bring head phones or did not know to ask for them would of liked to watch some TV but my bad. Everything went smooth enjoyed the flight."
Cons: "Did not have head phones !!"

Cons: "New plane but uncomfortable seats that don't lean back... There was only one attendant for the entire business and economy class cabin... The first class had an attendant but only one for the rest of the ENTIRE plane! There was a TON of turbulence and we never heard ONCE anything from the attendants or the pilots about the bad weather! Scared and uncomfortable the entire flight!"

Pros: "nice plane and crew"
Cons: "they loaded us even though the plane had not been supplied with fuel and food. So, we sat for an hour while all of that happened. unnecessary."

Pros: "Great"

Cons: "Lost my luggage"

Pros: "Same as above"

Cons: "Flight was originally cancelled then it got delayed an hour the next day because of a catering truck not being there on time.. Freaking joke"

Pros: "Every one was friendly. The plane was clean"

Cons: "They didn't have wifi"

Pros: "no complaints"

Pros: "Was never in Chicago."
Cons: "Was never in Chicago but my stuff was."

Pros: "Perfect, but I did upgrade to United's business plus."

Pros: "Aisle seat."
Cons: "They made my dad check his bag even though there was space."

Pros: "Worst flying experience ever"

Cons: "I was informed today that one of my checked bags was picked up by another customer who eventually realized it was not her bag. She brought it back to the airport and refused to turn over the bag until the airport compensated her. (How this happened I have no idea because I stood right by the entrance of the baggage claim and never saw the bag come out). The customer refused to return the bag until the police became involved at which point she agreed to write a note confirmed she did not steal anything. The bag then needs to be sent to me in 2 days and I'll have to verify myself that indeed nothing was taken from the bag. I'm very concerned how this individual came to be in possession of my bag considering, again, I stood right at the entrance of the baggage claim conveyor belt from the time it started to when it ended. As a result, this experience really made me feel frustrated and violated."

Pros: ":("
Cons: ":("

Cons: "The airline checkin is terrible and time consuming!"

Cons: "Never made it because of stupid United"

Pros: "The pilot got us there safely. Good deal of turbulence."
Cons: "Stewardesses were rude to many. Chit chatted with each other whole way, ignored passengers. "Too turbulent" to serve us a beverage, which was okay. Except first class got full service. Wrong."

Cons: "The layover wasn't enough time, especially since the weather was bad. The plane from Wichita to Denver came in late which made us late. Didn't appreciate sprinting with my luggage through the Denver airport"

Cons: "Didn't get to board this flight. Sat 14 hours with no compensation for my time. Laying on a cement floor! The people at the counter in Chicago were rude and not helpful"

Cons: "Check in"

Pros: "Nothing"
Cons: "Delays, gate changes, lack of notification, last minute changes."

Pros: "Arrived 30 min early"

Pros: "Friendly staff"
Cons: "$45 to put a carry-on item in the overhead bins is ABSOLUTELY RIDICULOUS!!!!!!!!!!!!!!!!!!"

Cons: "not clean"

Pros: "it was a fast flight and on time."

Cons: "Frontier website is cumbersome & not intuitive for check in & baggage calculations and classification purposes, needs a major overhaul. For that reason alone, I'll avoid flying Frontier in the future."

Pros: "Bag charged"

Pros: "The plane eventually got me to Chicago."
Cons: "The plane was inexplicably delayed by first 7 hours and ultimately 9 hours. Rather than leave at 7:30 pm Wednesday night, it took off at 4:30 am Thursday morning. Even worse, TSA didn't START work at the airport in Salt Lake until 4:30. I was fortunate enough to make the flight, but many others did not. Frontier provided no explanation regarding the delay, nor could they explain or even bother to care that the rescheduling occurred at a time Salt Lake passengers couldn't even go through security! Overall, this was an unacceptable experience."

Pros: "The crew was good- at least one of the guys was. Never saw the others so I can't speak about them."
Cons: "Very uncomfortable seats. A plastic chair with barely a 1/4" foam on it. Smallest tray tables ever- probably for the drink and snacks they charge you for. Not roomy at all. And more expensive than my other flight- only reason I took this one was because it was the only non stop flight to SLC. Paid $357 then was charged an additional $60 to pick my seat and for a carry on- what the heck was the $357 for?? Not to mention the plane was dirty- I guess they didn't have time to clean it between flights- not the crews fault I guess. I will go out of my way to avoid frontier from now on. It was my first and last flight with them. I'll take my chances on the plane they transported the Ebola patient in from overseas. How are companies with this many low ratings still in business?"

Pros: "Flight was delayed with no recognition or apologies. Seats were incredibly uncomfortable. Waited 1.5 hours in baggage claim for my bags... and again no explaination, no official to ask what was happening or when we could expect our bags. Word spread that the conveyer belt froze and the bags were stuck in the plane. Who knows. And as I write this: I am currently on a flight that has been delayed from 4:00 pm now leaving at 11:45pm. I will never book with them again."

Pros: "It was cheap. Although in the end I would have paid much more for a flight that actually got me somewhere."
Cons: "Flight was delayed from 4pm to 10:13 pm. Then boarding it too slow and we get in the plane at 10:45. Then, we wait at the gate for various reasons (?????) until 12:30, at which point the crew informs us that the crew has exceeded their time limit and we're returning to the gate. 8 hours of exhaustion and no flight,"

Pros: "normal routines"
Cons: "seats very uncomfortable no entertainment tray is tiny"

Cons: "Carry on price. Was not told about carry on price."

Pros: "Not a lot of people on the flight."
Cons: "No drinks or snacks?? How cheap is Frontier?"

Cons: "Crying babies on flights not enjoyable. That felt like the longest flight ever."

Pros: "Initial ticket price was low, but everything else has a cost. From checked to carry-on luggage, drinks and snacks on board. I prefer all inclusive pricing."
Cons: "Seats were very uncomfortable, probably the worst I've experienced. They are locked in an upright position so you can't lean back. That's probably good though because you are crammed in pretty tight."

Pros: "Nice people work at Frontier for most part. Very affordable flights due to cost cutting all over. As long as you just want a basic flight to and from, Frontier is solid."
Cons: "Try to charge ya for a coke, guess that's why they are so cheap, no freebies. Seats remind me of luxurious greyhound seats. Can tell Frontier cuts corners left and right to lower ticket cost. Delayed an hour, probably due to Ohare Airport."

Pros: "The air flight"
Cons: "Great"

Cons: "no free snack? not even a bag of peanuts?! disappointing"

Pros: "Nothing"
Cons: "• Questionable luggage policy • Fees for carry on luggage • Fees for seat selection • Very, very uncomfortable seating • Plane smelled bad • Will not fly again"

Cons: "Nobody smiles or talks to you like you're a human being. Their only concern seems to be getting through their day and checking their boxes to get paid."

Pros: "Flight went smooth and seats were comfortable."
Cons: "Charging for checked bag AND carry-on was bullshit"

Pros: "This is a terrible airline in every aspect, I would never recommend using them."
Cons: "The people are rude and must hate their jobs, the seats are the worst I've ever sat in and by the time you pay all their fees you may as well fly with one of the major airlines that know how to take care of their customers. Do not fly Frontier!"

Pros: "at least this flight was on time (this time)"
Cons: "They wait until the last minute to tell you there are fees for carry ons. I received no confirmation from Frontier about my flight and no communication explaining the unusual carry on fees. I didn't know that I would be expected to pay to carry on my small backpack and tiny suitcase until it was time to board. At that time, the customer service girl told me that it would $120 to check in my two tiny carry ons. She called for help and another woman told me that I would "only" have to pay $60 for the suitcase (which is the most outrageous baggage fee I've ever heard). At that point, I handed my ticket to the woman at the counter and asked her to charge my ticket. When I tried to board, I realized that I didn't have my ticket so I went back to get my ticket from the woman - she LOST it and needed to reprint it. When I got home, I saw that in addition to the $60 bag fee, they charged me $2.50 to print my ticket! Frontier's business practices are deceptive! Sure, the tickets were about $100 cheaper but having to pay extra for baggage fees and dealing with delayed flights makes it not worth the money at all!"

Cons: "there were too many delays and the situation was handled poorly. I do not plan to fly Frontier again in the future."

Cons: "The gates were not on my boarding pass, and I didn't enjoy hunting them down. When one of my flights landed, we circled the airport for 25 minutes looking for a place to let off the passengers."

Pros: "Flight on time"
Cons: "Check baggage was $35 & carry was $40. Pricing is way out of line. Online I picked & paid for 2 aisle seat across from each other. Boarding passes placed us separate. We changed 1 seat after on the plane."

Cons: "Baggage drop lines were unbelievable. Foreign travelers were in the same line as domestic. There were only four agents to handle 100s of passengers. When I checked in online, to select a seat I had to pay an additional fee and then was also charged for my carry on bag which increased my fare by $68. In addition they do not participate in TSA precheck which further delayed my security process. Although I had allowed plenty of time (1 1/2 hours) to drop my bag and get through security by the time I got to my gate my flight was already boarding. Additionally you are charged for everything on the flight even water which for a 3 1/2 flight is ridiculous."

Cons: "3 hour wait to get my baggage claim, bag drop and through security. Almost missed my flight. Very stressful."

Pros: "Aircraft"
Cons: "Nothing"

Cons: "Given a seat in row 4 which didn't recline- aghh!"

Cons: "Lots of screaming children, but I had to fly to Orlando."

Cons: "I don't like that I have to pay $40 for carry on and $35 for checked bags. I don't llike that I have to pay for seat. With all the up charges, this ticket is more expensive than United, where all is included"

Pros: "Easy quick boarding"
Cons: "No entertainment or courtesy drinks on the flight"

Cons: "plane 2 hours late. They charge for everything-even your seat"

Pros: "The flight staff tried their best to be friendly and accommodating"
Cons: "We had 3 aborted takeoffs due to a thruster module not activating. Then a staffing issue caused us to finally board the plane 5 hours after takeoff. We took off 6 hours after we were supposed to. The flight attendants either constantly lied about "only 5 more minutes" or were lied to by repair crews. I chose the frontier flight because it was $80 to $100 cheaper than other airlines, but after upcharges and issues with the plane I don't consider it worth it at all."

Pros: "How could you like anything..."
Cons: "They delayed the flight for 6 hours and it was a transit flight for me. I. Was supposed to be in Salt Lake City at 1pm and my second flight was on 5 pm. They arrived at 7pm! So, I had to pay for the hotel and for my second day flight again and they didn't even bothered to buy my hotel or flight ticket that they made me to miss. Never travel with this airlines."

Pros: "Landing"
Cons: "Everything, thr entire flight was a joke. I wad supposed to depart ohare at 10:30am and ny flight was delayed 5 hours! For it being my first time flying i was also extremely scared.. my gates were changed several times & it was all a displeasing experience. I was very unhappy with the customer service as well with the employees from frontier!"

Cons: "You should consider removing flightnetwork.com from your list of appropriate suppliers. Anyone thinking of booking the ought this site should consider all other alternatives before using this one. A mistake was made in the booking. Called within minutes of noticing the mistake. They would not provide any refund. Service was terrible. Very disappointing experience for someone who travels quite a bit."

Cons: "No complaint on this flight"

Pros: "Cheap..."
Cons: "Delaaaays"

Cons: "When I checked in, 16 hrs pre-flight, flight was WIDE open. I booked a $20 seat. Got on, flight packed. Asked to pay to upgrade my seat, I had to pay an ADDITIONAL $50 for an exit row & rec'd no credit for the seat I had originally purchased. Also, flight attendant Randall Stride was really liked to exercise his "power" as a steward. He was not very friendly."

Pros: "Everyone was friendly, will fly again soon to San Fran."

Pros: "The attendants were very laid back and nice"
Cons: "Nothing"

Pros: "Wasn' detlayed"
Cons: "Have to pay for every little extra thing"

Pros: "There is almost nothing positive to say about the flight, bounding tolerable."
Cons: "I have flown almost 200 times and this the worst experience I have had. A pathetic display of ineptitude."

Cons: "Where do I begin? Frontier Airlines had us sit in the plane for four hours before cancelling. We pulled away from the gates three times and even deplaned for 15 minutes before they decided to cancel. Just cancel it after a few hours, please. And then when I called Frontier for options, I was told the next available flight was four days away (Jan. 2) and did not offer any other options. Very disappointed in Frontier Airlines. The process of booking through Kayak was good, but I will never fly with Frontier again."

Cons: "screwed by baggage fees"

Pros: "The staff were very nice."
