Airline reviews

Pros: "Absolutely nothing."
Cons: "Honestly everything."

Pros: "Kosher snacks! Thank you! Very safe and controlled Covid procedures. Made me feel safe."

Pros: "Felt very clean and so glad they are not selling every seat"

Pros: "It was all good glad the last leg of the trip was pleasant."

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

Pros: "Very helpful and professional crew, despite some pretty snarky passengers. Seemed to go out of their way to accommodate everyone."
Cons: "Bigger seats would have been nice, but these were okay. Changing planes at JFK was tight due to late departure from Atlanta, but it worked out. Overall, no complaints and I would fly Delta again given the opportunity and choice. Thanks!"

Cons: "Small plane, feels cramped"

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

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

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

Cons: "No sandwiches for sale just snack boxes"

Pros: "Taco"
Cons: "Taco"

Cons: "It was ridiculously cold for 2 1/2 hours. When my seat mate asked for a blanket, the stewardess said she only had one more - then walked off. For drinks, they skipped several people. I had to catch her eye to ask for one and then ask her to get my kids a drink in front of me."

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

Pros: "All the attention bestowed upon me"

Cons: "Smooth on time flight"

Pros: "The crew really kept us updated on the many delays."
Cons: "There were SO many delays and they kept changing. At one point we got on and off the plane."

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

Pros: "Each employee on the plane was nice."
Cons: "N/A"

Pros: "Lots of movies to choose from."
Cons: "Delays out of MCI and late arrival, no hope for a decent seat on HNL leg, couldn't sit with husband, huge smelly seat mate, used up 10,000 miles on my account and paid higher price than current ticket price, middle seats, not happy"

Pros: "I am usually happy with Delta."
Cons: "Huge smelly person invading my space. Disgusted by his hot sweat on my leg. Used up 10,000 miles and paid too much (watched the fare go down several hundred dollars) and ended up with a middle seat. Not happy."

Pros: "Crew were ok. Not that comfortable."
Cons: "seat need to be more comfortable"

Pros: "Flight left on time"
Cons: "Gate crew had trouble identyfing boarding pass on their computer. Difficulty getting on plane"

Pros: "I loved the flight attendants and the desk staff everyone was so friendly and made me want to travel delta again."
Cons: "Delta doesn’t offer military spouses free checked bags and I found this out at the airport. It was disheartening, but at least it’s Delta and not the airline that is supposed to represent America."

Pros: "On time/ early arrival!"
Cons: "Most bring on 2 large carry ons slowing down boarding an de- planeing."

Cons: "Rude to passengers and then went to the back and loudly complained about other passengers. Very unprofessional."

Cons: "Small aircraft"

Pros: "Movie"
Cons: "Break downs again... At least this time they found another plane."

Pros: "Friendly service, comfortable seat, on time, no issues."

Cons: "Everything"

Pros: "Rare, the flight wasn’t so full that everyone was uncomfortable. The flight attendant staff were friendly."

Pros: "Not much"
Cons: "Late bumby ride"

Pros: "I flew on a basic economy fare (I understand the restrictions) and was seated in Economy Comfort +, so that was appreciated."
Cons: "I could see on the Fly Delta app that I had been placed in seat 10B, but neither the app nor my boarding pass gave me a group to board with, so I assumed that I needed to board with group 3, which necessitated gate-checking my rollerboard bag. Only when I approached the gate to board did I notice on the info screen that I had been "upgraded" to Comfort + and granted boarding with the Sky Priority group. I wish this had been clearer so I could have avoided waiting to board and gate-checking my bag. Minor inconvenience but room for improvement on Delta's part."

Pros: "This was not my original transfer flight but everyone was much nicer and helpful than serious and being rude. Love Delta, I did not flight United because I wouldn’t have met my United flight once landing in ATL. The Young African American woman who was at the gate was amazing and so reassuring that I would make my flight to Chicago. Would book Delta, just because of how nice she was to me."

Pros: "Flight was on time. Boarded quickly with no fuss."

Cons: "Delayed"

Pros: "The Delta people were solicitous, efficient and brilliant the whole way through. We had not a bit of trouble. Our first class seats were comfortable, but with the supplied blanket, pillow and poor air conditioning it was a hot flight. The cabin personnel were wonderful as per usual, and my tasty gin and tonic soothed any discontent. I wish I could fly this way all the time!"
Cons: "The private contractor handling wheelchair assistance was terrible. A Delta employee theorized that they do not pay enough to attract and retain personnel. Our pre-arranged chair was not there, multiple calls by our Delta assistant finally got us a ride to the chair holding area, but after about 45 minutes we gave up and shuffled off to the security area on foot. Thank goodness my hubby is mobile enough for that to have been an option. When we abandoned our wait we were still 4th in line for an attendant to push the chair. If Delta has any responsibility in this it would be in the retention and compensation for the private contractor."

Cons: "The delta studio didn't work with Android 8"

Pros: "Nothing including the captain who was making the boarding announcements at MCI who talked to me like I was stupid"
Cons: "My flight was delayed almost two hours which caused problems for me arriving late to business appointments in New York. My flight areas also late 45 minutes leaving New York. In both cases it was due to a late airline attendant this is increadably unprofessional."

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

Pros: "Not the wor st comfort,"
Cons: "Cannot even request seats before booarding, as they try to get us to pay more. The anxiety over separate seating for couples is not worth it."

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

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

Pros: "I had a great pilot on this flight. He always told us what was happening, why we had a wait on the tarmac in LGA, why he anticipated it might be a choppy flight, how to access in flight entertainment so we could be distracted. Gave us some trivia questions. Joked about Pokemon go, walked along the aisle talking to us. He was awesome!"
Cons: "Seats were uncomfortable. But what else is new?"

Pros: "Excellent piloting (good driving) and communication during a torrential downpour. That's important. The two hours on the tarmac were unavoidable, so appreciated occasional comments about the storm and circumstances. Interesting parking. I didn't know a plane could pivot like that. Also, flying through cumulonimbus clouds was thrilling. Thank you."

Cons: "passengers were cold and there were no blankets to be offered there were no hot beverages and it was very cold. all beverages were for purchase and yet no complimentary hot coffee nor tea, even if you wanted to pay"

Cons: "It was to uncomfortable to sit there in the plane for so long. I also noticed one of the flight attendants with the long brunette hair kept over looking me but would be in all the guys faces instead. Pretty sure it was a jelouse thing. The shorter brunette girl was really pleasant"

Pros: "Boarding was better than other airlines."

Cons: "Moving from one gate to another. The three hour delay. It appeared that no one person really knew what they were doing. The disabled in wheel chairs we left on there own. One elderly woman literally fell out of her wheel chair to the floor. I was discusseded by the events of the airline."

Cons: "Need one craft beer"

We were supposed to get into Asheville at about 8:00 PM, but finally arrived about 1:00 AM. I fly this route frequently and Allegiant has a terrible problem with on-time flights and communications with passengers waiting for their flights. I am not certain what the problem is, but it is a significant issue with them. Captain was "bubbly" and upbeat without properly managing the passengers' expectations. Bad public relations."

Pros: "It's convenient and inexpensive for one of my regular destinations. Though, over the years, I've experienced a few cranky employees at the Punta Gorda location. Just the opposite in Asheville, where friendly was apparently invented."

Pros: "The food vouchers for 5 hour wait and water/beverages available. Liked alligent app for boarding pass available without printing."
Cons: "The 5 hour wait while the plane was worked on was unexpected. Not a lot of extra space for a near 6 hour flight. Seats do NOT recline at all. The other plane they boarded us on smelled like dirty shoes or diaper."

Pros: "My book"
Cons: "The seats"

Cons: "No complaints."

Pros: "Nothing."
Cons: "They overcharge for bags and their weight limit is only 40 pounds. They leave the desk and hour before take off which doesn't help people who are running late. They charge you to print out your boarding pass. They don't even send the boarding pass through email, you have to download the app. Overall horrible customer service. When call for customer service you can't even get a human representative. I missed my flight and they didn't even have another flight to to accommodate me to get to my destination and no one at the front desk to talk to."

Pros: "Cabin crew was very helpful and polite. One in particular expressed a great sense of humor throughout the flight and had a great rapport w/ passengers. Flight was on-time. Fare was $111 compared to around $375 to Orlando. I was able to fit this flight into my scheduled so saved the company $$."
Cons: "Can't blame Allegiant for a noisy child, but there was a child across the aisle from me who shrieked and talked loudly THE WHOLE FLIGHT. I was trying to sleep and was NOT pleased. I like a good fare, but selling a can of Coke on the flight for $2 seems a bit extreme. Glad there are cut-rate airlines out there as an option, but I won't be flying them any more than necessary."

Pros: "The ground crew at mci was amazing!!! Help me out a tone"

Cons: "I wish the WiFi worked better and did not break down."

Cons: "Nothing"

Pros: "I did not get my luggage in Munich"

Cons: "Gate area very crowded."

Pros: "Most of the staff were good and helpful. Chicago had a snow storm and it was frustrating but not their fault...I did get a free drink on the plane for all the delays."
Cons: "The boarding process. Again, not the staff's fault."

Cons: "Boarding could have been better. If you have 5 groups you should have 5 lines — not 2. Also the terminal in Holland was extraordinarily cold."

Pros: "The attendant was nice about it"
Cons: "They tried to still get me home on the same day. They even put me on a different airline. It did not work. I am in Chicago for 24 hrs with one $12 meal voucher. A burger at the hotel is $17"

Pros: "Check-in process was smooth"

Cons: "Lost luggage’s"

Cons: "Unprofessional rude United staff"

Pros: "Nothing"
Cons: "They delayed so long that I had to reschedule for another day. This is after watching planes to other possible locations take off before United would switch peoples tickets. This was after a 4 hour layover completely disappeared. They should have been able to reroute planes or something after the first 2 hours of delays since it was for a weather phenomena that gives tons of warning (at least 24 hours)."

Pros: "A bit more leg and knee room."

Cons: "Good"

Pros: "Service and respect very good"
Cons: "Nothing"

Cons: "Gate personnel was unable to direct my 77 year old mother where package claim was. Being unable to go to the gate without a ticket I was unable to assist her. She wandered for about 35 minutes before I could decipher where she was at and was able to direct her by phone. The gate personnel just told her to follow everyone else. What a thing to say to someone."

Cons: "Na"

Pros: "Everything was perfect."

Pros: "Forthright on giving out informatiom"

Pros: "The crew was very nice."
Cons: "Due to a change that wasn't communicated, my seats were changed from check in to arrival at the gate. I was moved farther back and lost my window seat for a middle seat."

Pros: "Security was quick and easy to get through."
Cons: "There were only 2 stalls in the bathroom in our gate area."

Cons: "Buying basic economy is worst than Spirit. They single you out, and make multiple attempts to point that out."

Cons: "Flight was hour and half late missed connections spent 2 hours in Chicago"

Cons: "Late."

Cons: "I didn't get to fly because there was a mismatch in the booking for my name. Listed as Michael Murray Joseph but my name on my passport is Michael Joseph Murray"

Cons: "there was no outlets on the flight for me to conduct business and to use my laptop to access wifi."

There was someone at every stop wAitng on me with a wheel chair and they quickly got me to my next gate and also asked if I needed the rest room or wNted to stop and get a drink or food. Very very Attentive and friendly!"

Cons: "My itinerary had to completely change."

Pros: "Everyone was very friendly"

Pros: "Was nice"

Pros: "When l got to airport I was advised my flight had been canceled. Rerouted on United airlines thru Washington Dulles. Waited on Tarmac 2 1/2 hours due to bad weather, etherwise everything was good."

Cons: "I can not adjust the chair. Not comfortable."

Pros: "not much"

Cons: "EVERYTHING"

Pros: "Nothing"
Cons: "Frontier airlines has left an unforgettable experience to cherish in the years to come. I can say it was undoubtedly one of the impeccably worst airlines to travel ever. My flight was scheduled to travel from Kansas City to Chicago at 7:23 pm on Thursday. Initially I got an email from them saying the flight has been delayed and the new departure time is 9:45 PM. When I searched about it in GOOGLE it showed me that the flight has been cancelled, Furiously I called the customer service and they weren't even having an idea about the flight getting delayed in the first place. I had to travel to airport which is 50 miles from my place just to know that the flight got cancelled and the next flight is on Sunday. Due to their technical failure, I had to wait till Sunday to board a flight to Chicago(They gotta be kidding, wait 3 days to board next flight). I had to cancel few other flights, meetings and hotels as I am not able to board this obnoxious flight. Overall, The customer service is lackluster . Their website is very slow and has false information. The refund process is bad. They dont even intimate you through email if the flight is cancelled I am referring this airline to all my colleagues and friends. If you have a lot of money for procrastination, you are welcome to travel with this airline."

Pros: "Nothing"
Cons: "Everything"

Cons: "DELAYED"

Cons: "Charge for cabin lugguage and soft drinks"

Cons: "Be careful flying budget airlines. Their gate options are few if something goes wrong."

Pros: "Delayed 2 hours with no update information. As a frustrated passenger asked for answers. Called all over the nation for help. Upon boarding, was told Frontier had the right not to serve me. Refunded my money and then i had to book through another airline at 3am... long story short, nightmare."
Cons: "All of it."

Cons: "The seat headrest was uncomfortable hard to sleep.."

Cons: "The plate was late with no reason given."

Cons: "Showed up a day late. Oops!!!"

Cons: "I bought insurance for the flight but then was denied any compensationfor missing the flight due to circumstances out of my control."

Pros: "Upgraded us!"
Cons: "Told us the Wrong carrosol for our baggage."

Pros: "Getting off the plane."
Cons: "For starters, we scanned our tickets at one gate and boarded at another. First time I've ever seen that. There weren't enough Gate Agents to manage things so I waited in line for 40 minutes to pay your ridiculous $60 carry on fee. By the time someone was able to help me, my boarding group had already boarded. I ended up paying the fee and was forced to gate check my bag anyway as all the overhead space was taken up by the time I got on the plane. Nice work on your end milking that $60 from me. Since I wasn't able to check in ahead of time, I was stuck in the middle seat (I'm 6'5"). I would have happily paid an extra $250 to not sit in the middle, but thats besides the point. Just as I'm about to close my eyes, your stewardess gets on the PA and starts hawking Frontier credit cards for 20 minutes. If that wasnt bad enough, she had the audacity to shove an application in my face and remind me 'its the best credit card in the industry!' The credit card pitch and "buy 3 get 1 free' happy hour offers made the flight feel more like a sad Panama City spring break than a return flight after a long business trip. Alas! We landed at ORD 'on-time' which is always good for Frontier's stats. Unfortunately, we sat on the tarmac for 30+ minutes waiting for someone to man the sky bridge. Oh, and it was a nice touch deplaning in the international terminal returning from a Kansas City flight. Long story short, Frontier is now in the same category for me as Spirit Airlines. You fooled me once, but you wont fool me again. I'm just glad it was a one-way ticket. PS: when did airlines start soliciting tips for the flight crew? In all my years of traveling, I have never seen that before. Embarrassing."

Cons: "Long delays."

Cons: "That we had to buy drinks and snacks"

Pros: "Fast boarding, earlier departure and very earlier arrival."
Cons: "No entertainment"

Cons: "It's the most basic you can get... I never seen an airline that offers more alcohol than good onboard I spend over 3- 1/2 hr completely starving The seat doesn't recline no entertainment what's so ever . It's 2016 Let's stop this world war 90's"

Cons: "Arrived half an hour early but my seat was already sold. Wasn't offered to be put on a different airline and didn't feel like I was cared for as a customer."

Cons: "Drinking water serving was insufficient"

Pros: "That we eventually arrived"
Cons: "That we arrived 3.5 hours after we were supposed to"

Pros: "Not a thing!"
Cons: "The lack of empathy for my situation."

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

Pros: "Nothing."
Cons: "Everything"

Cons: "Arrived at my destination and items were missing from my bag."

Cons: "Never told about the 40 usd"

Cons: "Bag fees are crazy!! Also frontier does not participate in TSA pre check. So expect long delays at major airports."

Pros: "Everything was good"

Pros: "Fare"
Cons: "Uncomfortable seating and armrest design was pathetic boarding on cruel and unusual punishment."

Cons: "Paying $40 for carry on is expensive! Plane was uncomfortable!"

Cons: "I fly quite a bit. Take off was very rough. Also I have TSA Pre check but Frontier doesn't seem to have this so that was inconvenient."

Pros: "The prices"

Pros: "We didn't use the ticket!!!!!!!! This is not fair . The problem to register in the airport"
Cons: "Give me another ticket"

Cons: "You have to pay for water and a carry on ? Weird."
