Airline reviews

Pros: "MINT CLASS is amazing"

Pros: "crew was great."
Cons: "flight was 3 hours late with lame excuse. tray tables disgusting. felt unclean. cookies tasted gross. pa system not working. live flight not working either"
Pros: "Missed my connection"
Cons: "Making it to Charlotte"
Cons: "We waited in the runway for 2 hours after landing. Not the airlines fault however completely unacceptable."
Pros: "Crew was great, seat very comfy with good legroom."
Pros: "Everyone was boarded early so we departed early. Quick flight with pleasant flight attendants and nice snacks."
Cons: "The desk agent in Boston could be a little more pleasant."
Pros: "Not too full of a flight"

Cons: "Just flying with no 3h delays."
Pros: "Seats ok. Crew was great!"
Pros: "On point"
Cons: "Keep the good work"
Pros: "Sleeping in"
Cons: "Sleeping in longer"
Pros: "Crew was very nice."
Cons: "Tv did not work on a 4 hour 40 minute flight."
Pros: "Smooth ride great service"
Pros: "My seat was broken, so I couldn't recline, which made my lower back ache. The TV was fuzzy and several channels didn't work, and others would cut in and out"
Cons: "Took me asking twice where my coffee was. Flight attendant forgot."
Pros: "The JetBlue crew as always was friendly and helpful. Love the snacks. We like JetBlue far more than other airlines. This trip was partially due to a credit from a previous trip, which was cancelled due to medical issues. Getting a credit was very painless, and the agent was sooo courteous and helpful! Just a great airline!"
Cons: "Logan needs to be updated. The concourse is old, worn out, disorganized. Due to weather our flight was a bit late, but everyone kept us well-informed. A most pleasant surprise compared to a certain "Untidy" airline with cramped seats, lots of extra charges, late flights, and a crabby crew."
Pros: "Crew was nice. legroom seemed a little better than other domestic flights."
Cons: "You have to pay extra to sit in the exit row and there was no one in the entire row. Isn’t that a safery issue? Also, what really made me mad, instead of printing our boarding passes at the kiosk we went to a person (husbend had questions about Precheck) and she made us buy return tickets right then, on JetBlue. We had not decided on our return and wanted to leave it open. Can she do that? If not, I would like my money back."
Pros: "The leg room was great, and the trip was enjoyable."
Cons: "The aircraft itself was in average shape and dated (weathered seats, didn't have power supplies)"
Pros: "Seats are very comfortable"
Cons: "The flight is so much delayed. The flight attendent seemed not happy about me with a two year old, which makes traveling with a kid so unpleasant. When my kid asked to go to restroom, it seemed that we’re troulesome. My mom missed the water when they gave out drinks, but they did not come back for us. When I went to the back to ask for my mom, they said they’re cleaning up already."
Pros: "Friendly staff and a smooth takeoff and landing. All I could ask for. This was the 1st time that I flew JetBlue and I was impressed."
Cons: "The middle seat but that was probably my fault."
Pros: "I've been flying budget airlines for so long that I was almost shocked to fly an airline that actually cares about its passengers! I kid you not, when they offered coffee to all passengers, I was so sure they would charge us I turned it down. Then, I noticed no one else was paying for it. The next time free snacks and drinks came around, I made sure to grab some! I also appreciated the few extra inches of leg room in every row. Being 6'3", not many planes are designed with your comfort in mind. I fit fairly comfortably in a non-emergency row seat. Last time I flew to Baltimore for work, I had a terrible experience with a different airline. It was $200 less expensive than most airlines, but I ended up paying more in baggage fees and seats. It was only a 1 hour flight and My boss said, "Cheap things usually cost you more, in money, time, and emotion" and nothing has been truer. I always assumed that flights were always unpleasant experiences. Now, I know better."
Cons: "The seats, while having more than average leg room, still weren't very comfortable. Not that I'm expecting a luxury experience while flying economy, but I felt as though the headrest was farther back than average. I can usually fall asleep on a plane and wake up without neck pain, but I really struggled to even figure out a relaxing position this time around. I also did not know that JetBlue did not serve meals on cross-country flights. Or, on any flights for that matter. Had I known, I probably would've picked up a breakfast sandwich before boarding."
Pros: "I enjoyed the comfort once boarded and flight attendants warm welcome"
Cons: "Our flight was 3 hours late. Was supposed to leave at 10pm and left at 1:13 am!! Customer service at jetblue kept lying about the aircrafts whereabouts and crew. They barely gave us updates, and at one point once everyone started asking questions and getting upset, they disappeared from the desk for an hour at least. The crew was late, there was no food, customer service had quite an inappropriate attitude, and tvs on the plane barely worked,"
Cons: "Delayed 2 hours for lack of pilots."
Pros: "Friendly crew"
Cons: "Flight was delayed 2 hours and I never received notification. I got to the airport for a 4:10 flight to find out it was delayed until 6:15 and we didn’t board until after 6:30. Poor communication to passengers. Once on the plane the headphone jack didn’t work because something was lodged inside of it."
Pros: "Jet blue is great."
Cons: "Delays are not. We were on the receiving end of bad weather up and down the east coast which delayed our late flight many hours"
Pros: "Leg room!"
Cons: "Nothing"
Pros: "We love flying Jet Blue, especially because of the leg room. Everyone is so attentive. The snacks are great, too."
Cons: "Unfortunately one of the monitors wasn’t working."
Cons: "No working internet or video"
Cons: "Disgusting."
Cons: "Luggage claim was not correct. We were given wrong carrousel number. Our luggage was at carrousel #6, but we were directed toward carrousel #2, even the help desk person was saying “luggage would come to carrousel 2”. It was a big hassle. Fortunately, my next connecting flight is after 6 hours."
Cons: "Overhead light and recliner weren’t working"
Pros: "On time flights with punctual boarding and early arrival Polite flight attendants Pilots pointed out areas of interest during the flight Comfortable take off and landing Unlimited snacks and beverages, even on shorter flights Free entertainment, even on shorter flights"
Cons: "nothing"
Pros: "Plane departed early and arrived 40 minutes early. Well done"
Cons: "Prefer BLUE Chips rather than cheese x AND usually they call for VETERANS to board before the start of general boarding. This is the first time Jet Blue DID NOT extend that courtesy"
Pros: "Seats were comfortable (an Airbus A320). Entertainment system adequate. Smooth flight."
Cons: "Two dogs in cabin. They were mostly well behaved. A group of six children loosely supervised by a couple of adults. The children were allowed to wreak havoc on the center section of the plane's cabin."
Cons: "No in flight ent or wifi"
Pros: "The seats are comfortable. Enjoyed the TV. JetBlue is our preferred airline. Haven't had a bad experience."
Cons: "The free snacks could be a lot healthier, i.e. apples, hummus,"
Pros: "We arrived earlier than expected and easy boarding."
Cons: "The flight gate was changed last minute--only one or two announcements."
Pros: "JetBlue did a good job, as usual."
Cons: "There was a screaming Infant in the seat next to me that continued to scream for the first hour and a half. I requested earplugs, and wore them under my 34 dB noise isolating earmuffs (which were made for use at a gun range). The screaming was still loud enough to give me the worst headache that I've had in 4 years. Once this baby stopped, the baby in the row behind me began to scream and the one across the isle from him/her joined in. I would happily rebook with JetBlue if there was an option to not be seated within 5 rows of a toddler."
Pros: "Leg room, comfort, travel time"
Cons: "Flight was late an hour, and the snacks were okay."
Pros: "Boarding from back of plane"

Last time flying Delta."
Pros: "Overall service was great."
Cons: "Flight was delayed 5 hours."
Pros: "Early and middle seat was open!"
Cons: "Coffee tasted like fish. :("
Pros: "The crew on the airplane was great. We had 2.5 hours turbulences but the crew started to give out drinks as soon they got the ok from the pilot"
Cons: "We went in LGA to the Baggage drop off and the employee there was super rude. On the flight to New York with Delta we had to check our carry ons at the gate because it wasn't enough room for bags in the airplane.so we asked when we checked our one suitcase if we can/should check our carry ons to avoid having to do it at the gate. The delta employee told me sure no problem. He checks in my one suitcase I purchased gives me the tracking paper and says ok have a good flight. I asked him so what is with our carry ons and he told us that that would cost 25$ and we can't check those in at the drop off?!?We ended up taking the carry ons with to the gate and then off course there wasn't enough room on the airplane that we had to check it in. And surprise it was free?? We had never issues with Lufthansa, icelandair etc. with checking our bags at drop off to not needing to carry it around and than still end up to check it at the airplane. Every airline has been more than happy that we volunteer to check our bags that they don't have the trouble at the gate."
Pros: "wonderfu crew... very helpul`"
Cons: ".."
Pros: "Everything went great. Flight left a little late but was fine and only arrived a little late. I like the side wings on head rests really help."
Cons: "Seats are always hard on long flights."
Cons: "Flight delayed by 2 hours- was just sitting in the plane for couple hours before it took away"
Pros: "Plane was on time."
Cons: "My seat assignment was in the last row of the plan when the plane was not full"
Pros: "I usually have had great experiences with Delta. The meal selection was limited. By the time they made it up to my seat they had run out of what we wanted. Also, the entertainment system at my seat and my husbands wasn’t working well. One of the bathrooms had a cabinets Tvst oliiiooooiiooooioiooiiiooiio"
Cons: "insufficient overhead luggage space"
Pros: "The woman who helped us at the desk by the gate was possibly the single most helpful, kind Delta employee I’ve ever met. She wheeled me down the jetway and upgraded our seats. I wish I knew her name. She has very curly dark blonde hair and is petite."
Pros: "The staff really helped me out getting on standby so that I didn't have to wait for a 9 hour layover. Overall great experience and great staff."
Cons: "Check in lines were crazy long"
Cons: "My daughter was stuck in SLC for 5 hours because there 1 cancelled flight and 1 delayed flight. It was very upsetting not knowing when she going to arrive in Denver."
Pros: "The staff. They were very helpful and polite!"
Cons: "We didn’t leave on time"
Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"
Pros: "gate staff were great"
Cons: "plane cabin staff looked overworked"
Pros: "Delta flights run one time and their fleet seems newer than most with comfortable seating. Having free movies in the seat back ahead of you is a big plus with a good selection of movies. Snacks are good and crew is always friendly and accommodating. We fly almost exclusively with Delta for the aforementioned reasons."
Cons: "Boarding is a hassle no matter the airline with few exceptions. You would think someone could figure and efficient method to get people on the planes. I suppose it could be the public that is the problem. Not a problem with Delta they run a good airline."

Cons: "LOST MY BAG IN BOSTON BEFORE EVEN TAKING OFF!!!! Did not make it, and then won't deliver it when it makes it to Kathmandu! This is most distressing."

Cons: "Jet airways sucks"
Pros: "Free first checked bag, comfy seats"
Cons: "Would have liked more movie selection"
Pros: "The only flight that was a bit better was from Mumbai to Hyderabad."
Cons: "Almost the entire trip, due to the following reasons: 1. The online check in process didn't work at all. The Delta staff at the Boston airport weren't pleasant and courteous at all. 2. Poor coordination between Delta & Jet Airways - the meal preference was selected before flight at the Jet Airways website but the same didn't get registered properly, even though the website confirmed to me that it was all set. This resulted in appropriate food not being available to the customer on the flight from Boston to Amsterdam. The customer had to literally starve on the flight. 3. The pursers and stewards on the flight from Boston to Amsterdam weren't pleasant and courteous at all. For anything they were asked, their responses ."

Pros: "Seats were pretty comfortable. We were allowed to deplane down a staircase off the back of the plane. Very cool."
Cons: "N/A"
Cons: "Sat waiting for gate for 30 min"
Cons: "Overall good business class trip."
Pros: "The flight itself was fine."
Cons: "The gate change was not announced on my phone app (changed from E7 to D49). I hate leaving out of Terminal E at MIA. There is no point to having TSA Pre-Check if you have to stand in line with people who don't have it. I have to remove my liquids and laptop. It's such a shabby, run-down terminal."
Cons: "PHX airport baggage claim was a mess. I had to wait 40 min to pick up the luggages."
Cons: "The gate attendant was very hard to understand and so I couldn’t hear what she was saying."
Pros: "Crew was good, flight was on time"

Cons: "N/A"
Pros: "Early and easy"
Cons: "Was perfect"
Pros: "Seats were too tight and too close together."
Pros: "Crew was nice and kept us updated."
Cons: "Flight arrived 20 minutes early and we still deboarded 20 minutes LATE. Wifi on flight is ten dollars instead of being free and they use plastic cups for the drinks which I am sure is not recycled."
Pros: "Nothing in particular"
Cons: "Outlet did not work"
Pros: "Everything"
Pros: "On time, kept informed."
Cons: "We sat in Charlotte on the runway and had to run to our connection. The airport seems too small for the amount of traffic. We usually try to avoid Charlotte, but it was the only way to use frequent flyer miles"
Cons: "Food"
Cons: "Not having boarding passes for the entire trip and not checking luggage thru to Charlotte was a hassle."
Pros: "Friendly attendants, plenty of coffee. Great service."
Pros: "The first leg had awesome pasta.Then, on the 2nd leg, Philly to Denver, they had a "pay for meal" option for turkey with Chutney sandwich - again, delicious. I should add that the service was very good as well."
Pros: "The flight to Washington was fine. It was the flight back that I have issues with."
Cons: "My issue with flying back American is that...I didn't. They boarded us on the plane, moved down the tarmac, and then checked to see that we had a brake problem. They took our plane out of service (which I get, I would want brakes before takeoff), but then they never updated us on our status, until I physically went to the counter to ask an hour later. This is when they informed me that the flight was cancelled and we were rebooked on the 9pm flight (Mind you, this is 12:30p and I have a 2 year old with me). Luckily, I was able to book JetBlue and get home earlier (8:00pm)"
Pros: "Staff was great!"
Cons: "Seats were really uncomfortable up and reclined. Overhead baggage was full by the time I boarded and there was no enforcement of the carry-on baggage sizes... This needs to be addressed and contributed to our lack of comfort, noting this was the last leg of an 18 hour journey. My body still hurts today after a good nights sleep."
Pros: "We had to wait in the airplane upon arrival in La Guardia NY because wheelchair was not ready."
Pros: "The flight crew was professional, friendly and competent. They served the dinner as early in the flight as possible."
Cons: "This was a plane with central screens along the aisle, and the airline chose to broadcast a sci-fi action movie with almost constant flashing blue light, and violent action scenes. This was first of all a movie that many people, including me, would never choose to watch, but since it was on the aisle screens there was no getting away from it. It was also unsuitable for children, even without sound. But mainly, I object to the showing of any film in that situation - only aisle screens available, and on a night flight where most of the passengers are trying to sleep. I was awakened several times by the flashing lights. Other things: one of the bathrooms was not very clean, and the plane felt like the usual cattlecar, with just 3 seats on each side of the aisle, which is unusual and unpleasant for a transatlantic flight."
Pros: "Good service from crew members"
Cons: "The flight was delayed for 2 hours"
Pros: "Good crew Lucky to get better seats!"
Cons: "Poor Selection of entertainment not enough screen"
Cons: "American Airlines made me check my carry-on luggage, despite there being many open overhead compartments visible on the plane."
Pros: "Old school seat. No foot rest. Small plane to go coast to coast."
Cons: "UI on the entertainment system was horrible."
Pros: "Entertainment."
Cons: "We sat on the runway for 3.5 hours while the crew cleaned up a fuel spill and we waited for a different co-pilot."
Pros: "The flight was on time and the crew are nice with the people"
Cons: "Too crowded not able to take my other luggage on board."
Pros: "There's nothing good about AA"
Cons: "One of the few things SouthWest, Alaska & United did was the proper queuing of people to get into the plane. AA is a free for all - those who follow regulations will fall behind. In this flight from Boston to LAX - I heard there were 80 Priority checking - are you kidding me. Group 1 does not help if I have 80 Priority seating and one family took 12 people in with one elderly. It's good to place Elderly and Military up front first - but to take the Whole entire family - that's not fair - you have 8 able bodies who should be in line with the rest of the crowd. Also who heard of 80 Priority check ins - normally, that's Group 1. Never flying AA unless I a desperate."
Cons: "When your on your honeymoon it sure would be nice to have a seat next to my husband like we requested."
Pros: "the flight was on time coming and going"
Cons: "The customer service from AA representitives in the airport was completely unnacceptable and the absolute worst service I have recieved in an airport to date! One incident during this trip was as follows: When arriving in Charlotte and running to catch my connecting flight, I arrived as the lady at the desk was closing the door, she looked at me and rolled her eyes. When I went up to the desk along with the other passengers arriving from the same flight as me the AA representative said "Hurry up , I want to go home!! At a point I'm just going to cut you off and that will be it!" She was of no help to me in anyway amd was forced tonstay the night in charlotte ; Normally this would not have been such a big deal, However I am on emergency leave from the Navy rushing home because I have a very serious family emergency, that representitive was very lucky I held my temper! From now on thanks to the poor unproffessional customer service I received I will no longer be flying American Airlines!"
Pros: "Crew was professional and friendly."
Cons: "The plane was delayed by an hour and thirty minutes because it was coming from another airport where it was delayed."
Cons: "The plain was cold It’s the first time ever I had get my coat on because of the temp No in seat screens and expensive WiFi"
Cons: "I paid $100 for an upgrade on a United which turned out to be the first row, and right beside the rest room (which was erroneously showing as occupied for the first 20 minutes). The traffic made it feel like I was sitting on a bench in Grand Central Station. I chose an aisle seat but ended up mysteriously in the middle seat. I had extra leg room but if I’d eaten the free 5 pretzels I wouldn’t have been able to fit it my seat any longer. The WiFi wasn’t working for the first hour of the flight. The flight attendant got really annoyed when we didn’t look up when he came by with beverages the first time. We all had headphones on and were looking at our personal screens. The activity by the rest room was constant so we didn’t notice it wasn’t just someone waiting for the loo. The luggage took so long to come out I thought my conference would be over before I got it. Overall, I thought it was bad and confirmed why I don’t fly United. Old, dingy planes, poor service. The pilot was pleasant and communicative so there was at least that..."
Pros: "Wonderful flight.... great crew!"
Pros: "The crew was attentive, professional, and courteous"
Cons: "5 hour delay"
Cons: "Not being delayed for 2 hours"
Pros: "I liked the ticket price."
Cons: "The seat was very narrow with absolutely minimal leg space, and a carry-on bag was not included in the fare."
Pros: "The crew and pilot were terrific. Soft take off and landing. We flew past Toronto over Lake Ontario. Great views!"
Pros: "Great take off and landing. My ears were not even plugged up after landing. Great piloting skills by the crew."
Cons: "They made me put my carry on under the plane."
Pros: "The captain was wonderful"
Cons: "The crew were jerks"
Pros: "Things were new"
Cons: "Seats were smaller, legroom was less, seatbacks when fully upright push your heard forward so when I fell asleep, my head kept falling, NO FREE ENTERTAINMENT. They tell you to download the app mid-flight to get free entertainment, but you need to pay for wifi to access the app store."
Cons: "Over two hours delayed. Had to carry on carry off my bags that were heavy. Messed up my schedule. Had to incur extra charges at San Diego destination due to the inconvenience."
Cons: "Seats space was very toght"
Pros: "The flight attendants were so nice, and although our flight was delayed and hour and fifteen minutes and our layover was an hour and fifteen minutes, we were able to make our connection! Since our connection to Portland in Denver was the last flight of the night, they were able to hold it for us. This was wonderful because there weren’t many flights out that weren’t booked solid for the next day. The attendants on this flight were great about updating us with information for the connections and telling us when we would land in Denver."
Cons: "The plane was delayed over an hour for cleaning. It was frustrating to say the least."
Pros: "Nice jet, nice ride, fun trip, amazing gate agents!"
Cons: "Actually everything was great."
Pros: "The crew was excellent, very friendly and helpful. the pilot announcements were unintelligible. I appreciated that the crew anticipated that overhead luggage space would run out and offered gate checking of luggage all the way through to my final destination. I took advantage of their offer and it made my connections so much quicker and smoother"
Cons: "The room for seating is way to crowded, I need more leg room and don't feel I should have to pay extra for a minimum requirement for air travel. Beverages were skimpy, should be offered more often."
Pros: "a little bit more foot-room than my previous flight on a different airline."
Cons: "Inspire of making it clear all through booking, check-in and seat assignment, I was assigned a seat in an emergency exit. I told crew before I boarded that I could not open the emergency exit at assigned seat, due to an injury. I had to board almost last waiting for them to find someone who would take that seat. Then they put me in a non-reclining seat. I was given the wrong free beverage and the crew never came back. So I had nothing to drink on a 4+ hour long flight."
Pros: "Free movies on the plane, because of errors."
Cons: "4 hour delays both ways. We missed our connection flight due to delays on the way home. That connection was the last flight out of that airport home. We ended up having to sleep in the airport overnight, because United wouldn't pay to put us in a hotel even though the delay was because of a mechanical error on the plane. Our 5 hour flight turned into a big ordeal."
Pros: "Smooth and early."
Cons: "Was afraid I may get beat up. Flight attendants were quite stern."
Cons: "The boarding process gives me anxiety."
Pros: "Nothing"
Cons: "They would not let me travel with one carry-on and one smaller item. They made me check one item. This has never happened to me on a flight before. During the flight and in between during the layover all staff members were very rude. I will never fly with united again."
Pros: "Efficient"
Cons: "Bumpy ride"
Pros: "Scored anot exit row for no extra charge"
Pros: "Great flight Left in time Arrived early"
Pros: "Flight back was delayed 10 hours and my daughter was stuck at airport and had very little sleep . Upset about this experience and won't fly united ever again"
Pros: "Nice, big plane"
Cons: "The entertainment went out."
Pros: "better seats than in the past"
Cons: "flight attendants fighting with a passenger"
Pros: "Nice plane very smooth flight"
Cons: "Plane was late and missed connection to Wichita"
Pros: "Once flight began it ran quite smooth"
Cons: "I chose seats when I booked the tickets. So... Not quite sure how both myself and my partner didn't end up seated together, and both ended up in a middle seat sandwiched between 2 overweight people... Are you little people profiling to break up the overwhelming number of big people? another couple with 2 kids were also broken up into distant areas on the plane. I know everyone complains about so many things, and this wasn't the end of the world, but still, it's not ideal. The seating/etc seemed more disorganized than usual for this flight."
Pros: "On time, friendly crew, bags got through timely"
Cons: "Nothing in particular."
Cons: "Unreliable wifi."
Pros: "The crew was nice and boarding went smoothly. I'm glad that they now offer complementary small snacks."
Cons: "I can never get the entertainment to work on my personal device and the seating is always tight in economy class."
Cons: "The second leg of my trip was a disaster. Dealparture tike change 5 times from 6:50 PM to 10:15 PM. Exhausting! Then the flight attendant was aggressive and rude."
Pros: "Good flight attendants."
Cons: "Nothing"
Pros: "On time or close to it. Nice crew."
Cons: "Bumpy but pilot did her best to find the best altitude."
Cons: "It was over 7 hours late. The second plane was old and in poor condition. The crew attitude des were awful."
Pros: "Getting off the plane"
Cons: "Bathrooms weren't working, huge lines in aisle, lackluster service. Overhead bins were full by Group 3. late takeoff."
Cons: "Delays, had to stay overnight in Chicago since we arrived 6 hours late"
Pros: "The attendants were the best I have ever experienced. Traveling with my disabled father can be very hard but it was great. We're always going to fly United!!!!!"
Cons: "Nothing"
Cons: "Our flight was 2 hours late, the customer service was horrid and didn't even acknowledge people who needed help at the front desk. They we're too busy talking to their coworkers. We then get on the plane and it's old, run down, and the take off and landing were the roughest I've ever encountered. Nobody was remotely professional and we landed after our rental car company closed so we had to go back to the airport the next day. NEVER FLYING UNITED AGAIN!!!"
Pros: "I didn't die."
Cons: "I almost died. There was some sort of overheating happening under my seat requiring constant monitoring by the crew and myself; I burnt myself on the wall of the plane. It was terrifying. The flight crew was able to rule out fire but said all they knew in the cockpit was that it "has something to do with the wing". REFUND PLEASE?!?!?"
Pros: "I liked how the flight attendants treat people in this flight. Thank you all."
Cons: "I didn't like how long the flight was, but that is not up to anyone to decide. I liked my stayed in the airplane."
Pros: "The crew was courteous and nice. Due to a 2+ hour delay we had free movies on the flight."
Cons: "The fact that our incoming flight was delayed more than 2 hours."
Pros: "Nothing."
Cons: "Recently United decided to cancel all of their flights to Denver due to an April snow storm. United was the only company that chose to cancel rather than delay flights. Our flight was cancelled 24 hrs before any snow fell. Their solution was to offer us another flight over 72 hrs out. After spending 6 hrs on the phone with this company (not exaggerating) I feel entitled to say that this company holds zero accountability or concern for their customers. We had to spend an additional $500 to get to our destination last minute through JetBlue."
Pros: "I liked that 1 out of our four flights had more room & personal tvs."
Cons: "I did not like the fact that out of our four flights three were not too comfortable... & no tvs on three out of four"
Pros: "The flight was delayed but the gate staff and flight attendants did an excellent job helping us to get quickly to our connections"
Cons: "Did not like the delay that happened and we arrived 2 hours later. I was suppose to arrive 10:30 and I arrived 12:30. I wasn't able to go to work for that reason."
Pros: "The crew was professional and friendly."
Cons: "Both my outbound and inbound flights were 1 hour late. The tiny tray tables and lack of reclining chairs make Frontier's planes more uncomfortable than others. Being charged for a basic beverage or snack also seems "chintzy" when you've already charged me for my flight + my seat + all baggage."
Cons: "Have plane depart on time."
Cons: "The rep. at the baggage drop off was being unnecessarily unkind. Though she did not attend to us, it was obvious to all those in line she was upset. She gave her co-rep. attitude &created a very uncomfortable environment. We do not know either of their names. The negative rep was the AfricanAm lady."
Cons: "Flexibility with the flight."
Cons: "Flight was delayed by almost two hours so I missed the flight from Denver to Charlotte. Because of the way this flight was sold to us and booked through Kiwi.com, there was nothing that could be done to get me on another flight. The only option was to wait for a Frontier flight which wasn't available until Monday morning. I had to book another flight on a different airline at a cost of $600."
Pros: "Everything else was fine."
Cons: "The flight was delayed 30 mins prior to boarding for 6 hours. They were missing a part that needed to be ordered. What I don't understand is why they couldn't have emailed everyone to notify us so we weren't stuck in the airport for 6 hours."
Pros: "The actual price was very good, but the seat and bag fees were disappointing."
Cons: "I don’t care if there’s food or not, but nobody should have to pay for a seat or luggage."
Cons: "Three hour delay which almost made me miss my connecting flight. Not even an apology was offered. As we landed my connecting flight was boarding and no attempt was made to deplane the delayed connecting travellers first."
Pros: "The staff were very pleasant"
Cons: "The seats are small and don't recline"
Pros: "We appreciated the cheap airline ticket prices."
Cons: "We were outraged by having to pay $45 for each piece of luggage, including carry ons! After these hidden fees, our tickets would have been cheaper for a well established and popular airline."
Pros: "The staff was so kind and made the trip fun, very fast flight but so enjoyable. I honestly will not fly another airline if frontier is available. And best of all it was inexpensive... other flights were pushing 500$ and I got this ticket for 200$ overall great experience!!"
Cons: "Only thing was I couldn't buy a drink with cash which is all I had on me but I think that's every airline so nothing frontier specific :)"
Cons: "You're charged for everything. When checking in you have to pay for your seats... what's the point of spending $350 on a ticket if you have to spend another $60 on your seat. What was the ticket for?"
Pros: "I lived"
Cons: "definitely would be better if there was USB ports and if I'm gonna spend $7.99 on a shot of whiskey it would at least fill the glass up"
Pros: "The online price."
Cons: "All of the hidden fees."
Pros: "It was cheap"
Cons: "I had to find another flight on my own to replace the second leg of my trip from Denver to Salt Lake City. The customer service was ridiculous."
Cons: "Uncomfortable seats - don't recline! Rude crew, create an impression if they're doing you a favor by being there. Flight significantly delayed. No clear announcements. As a frequent flier, didn't expect a Spirit like experience from Frontier!"
Pros: "The cheap price"
Cons: "No complementary drinks such as soda or snacks such as peanuts or pretzels"
Pros: "The staff was friendly."
Cons: "The flight was delayed, and there was poor communication in the waiting area other than making sure your baby item extras were tagged. People with children were told to be ready to board early, but we were the 3rd group to board. I had to pay $3 for my daughter to have juice to drink (no beverage or snack included) after I had to pay extra to get seats assigned to be together with my 3 year old."
Pros: "The flight left 5 hours late, spent a good 30-40 min on the runway, the bagage claim was never marked and announced after most people had figured it out, and they lost two pieces of our luggage. I guess that is good service, since the common standard today is being beaten bloody and dragged off the plane. I wish they had communicated the reasons for the delay, given accurate estimates, etc"
Pros: "Price before additional fees"
Cons: "All the extra fees. Pick a seat fee? Checked bag fee? Carry on fee?"
Cons: "After being left on the plane for a long time and not even offered ice water or anything. We were released out to the lobby. And then shortly after asked to get back on the plane where it was EXTREMELY Hot. I would NEVER go frontier again."
Pros: "If you're flying frontier your not doing it because of how luxurious it is. You're doing it because it's cheaper than most. Yeah they rob you with the bags and paying for anything not water on the flight. But what can you expect for the cost? The crew is almost always good from experience, but customer support online is a nightmare. It is by far and away the worst customer support services I have encountered. The actual people that work at the airport and fly are good but if you need to make a call you are screwed."
Cons: "From the get go this flight was terrible. Frontier at DCA doesn't open their ticketing counter until 2 hours before the flight leaves - this means that even though there were 15 people in line, the worker just walked away and left an empty desk after she finished helping the flight before us. The flight attendants were unhelpful and condescending; a man complained because something from the overhead bin was dripping on his head and he received one cocktail napkin in response. They made you pay for sodas (despite me taking this exact flight from DEN to DCA 7 days earlier and getting sodas for free) and overall it was a disappointing experience. I sincerely hope Frontier gets their act together soon, they've become a disappointment of an airline."
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: "Fairly good ticket price"
Cons: "Too hot on plane Extra charge for luggage"
Pros: "Price of flight"
Cons: "When I went to sit down in my middle seat there was two larger women on either side of me. If I was any bigger, I am a 5' 4" 110 lb woman mind you, I would not have fit in between these women. If you keep shrinking your seats, no one will fly with you. In the future, I will be booking my flights further in advance with an airline that has seats to accommodate someone who is the size of a full sized man or woman."
Pros: "The price of the flight"
Cons: "The fact that frontier will not transfer checked bags to a different airline. If at all possible, I will never fly this airline again"
Pros: "Flights were overall good. Airplane crew was attentive and cordial- sats are comfortable although not reclineable. Flight was on time and even arrived ahead of schedule"
Cons: "Check in crew was not very cordial/friendly- Did not have any check in Kiosks open at MSY and no one around the dask for over 40 minutes Tried to check in online 12 hours prior to my flight so I could get discounted check in bag prices and it would not accept my email as contact so it would not let me finalize the process so had to pay full price at airport- Although flight arrived early- had to wait almost one hour for luggage"
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"
Cons: "Boarding. Why can't airlines go back to the old way of boarding from the rear of the airplane first?"
Pros: "Arrived early but then had to sit on tamark to wait for open gate. When able to check in at terminal desk, was able to go through TS-Pre check when I got my ticket."
Cons: "Seats too close together. Crew didn't come through cabin very often to check on passengers or pick up trash. Don't like use card for few dollars of drinks or food. Terminal desk wasn't open when I went to check in 2 hours early. Had difficult time with kiosk. Paying $40 each for carry on both ways and more for a window seat. Flight was delayed from Denver to Madison."
Pros: "I liked the timeliness of the boarding process."
Cons: "I did not like the attitude of the one of the male flight attendants and found that he was unprofessional. The seats were the most uncomfortable seats I've had to sit in during a flight. The airline doesn't offer free complimentary drinks and they still don't offer a TSA precheck option for their flights."
Cons: "Swindled at the airport to pay $40 for a carry on, with no heads up during the booking process."
Pros: "I was impressed with how smooth the takeoff and landing were in addition to the kindness of the crew."
Cons: "The hidden charges and random fees got me sweating as they piled up, but nothing too terrible that it actually made flying Frontier more expensive than other airlines."
Cons: "Seats are so uncomfortable. Then with all the extra fees this discounted fare cost more than if I would've went with my usual pic of airlines. Sat on the tarmac for for over 30 minutes after leaving late from Austin. We had originally expected at least an hour and a half layover and planned on getting some dinner in Denver. With The delay in leaving and sitting on the tarmac we only had about 20 minutes most to find something quick to eat"
Cons: "Mechanical issue with the plane was reported the night before and not looked at until next morning after all passages had to be boarded. This caused all passengers to have to be unloaded and wait numerous hours before knowing if/when we were leaving. They passed out a handful of breakfast voucher then stopped until about an hour later they gave the rest of us our vouchers."
Pros: "It was on time. The crew was generally friendly. The take off and the landing was pretty smooth."
Cons: "I didn't like the cramped feeling. I was in the aisle so there was nowhere to rest my head."
Cons: "Flight left 45 minutes late with no alerts, uncomfortable planes, tray "tables" couldn't hold more than a deck of cards and a small coffee, nickel and dime for everything, no wifi"
Pros: "Flight delayed unapologetically- making me miss connecting flight on frontier only hours before the flight, which they were unapologetic about"
Cons: "Fee's for luggage and carry ons. In other airline its already included Fee's for luggage and carry ons. In other airline its already included Delayed flight"
Cons: "there was a charge for carry on that was not disclosed when i bought the ticket. further, i was unable to get the ticket from home so had to go through the extra time to go to the ticket counter."
Pros: "The crew was friendly and the plane was clean. Seats aren't too bad either."
Cons: "This is the only airline I know of that charges for a carry on bag as well as non-alcoholic beverages. Also, the charging for seats is ridiculous."
Cons: "The flight was 2.5 hours late but none of us knew what was going on. We waited at the terminal without any real updates. Seats were incredibly uncomfortable and not spacious enough for adults. Also, $30 for a carry-on!? I was not aware of the extra charge until the day of, bad customer service."
Cons: "I took off time from work today to catch a 5:25 flight from San Francisco to Denver, arriving at 9:05. It's now 11:55 pm and I am still sitting at gate 21 with a whole bunch of people other waiting for a plane to arrive. My only choices are to wait of this plane to show up, or come back in the morning to take the 5:45am flight. I have business meetings in Denver tomorrow morning. I had a car rented and a hotel reserved. The car rental in Denver closes is 5 minutes. The thing that's the most upsetting is that we keep receiving erroneous information. The original departure time was 5:25. Then we were told 6:00. Then we were told 9:00pm. Then we were told 12:03, Then we were told 12:20. Now we are being told they don't know when the plane will arrive to take us to Denver. I will NEVER fly Frontier again."
Pros: "The crew was great, and boarding was easy."
Cons: "Well frontier advertises these cheap flights, but then charges for seats, bags, drinks, and snacks. These flights end up being just as expensive or more expensive than other airlines!! Super irritating. Doubt I will fly frontier again."
Pros: "Our flight was cancelled and there was no customer service to help us rebook - we are heading to the airport now."
Cons: "Lack of customer service"
Pros: "Nothing"
Cons: "Service, seats, everything...not worth the cheaper price"
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: "The crew was awesome."
Cons: "Extra hidden fees for baggage, food, and seating. Next time I would opt for the more expensive flight for more comfortable ammenities."
Cons: "Frontier planes are fitted with the thinnest excuse of a seat that I have ever seen. I am a 5' 3" 115lb girl that has flown a lot. Seats nowadays are uncomfortable but frontier takes the cake. Seats were literally just an inch of plastic completely straight backed. I was so incredibly sore by the end of my 2 flights that I was holding back tears. They have an extra charge for everything including bags and soda. I will never fly frontier again."
