Airline reviews

Pros: "Absolutely nothing."

Pros: "The accommodation to the military service members!"

Pros: "Delta is doing a great job keeping everything calm and clean during this pandemic!"

Cons: "Nothing all excellent"

Cons: "It was great! Nice job Delta !"

Cons: "Wouldn’t change a thing! I don’t always fly! But when I do!! I fly delta!!"

Cons: "The main economy seats were far too narrow."

Cons: "1.5 hour delay...no reason given!"

Pros: "All the attention bestowed upon me"

Pros: "Love the fact that the head rests move to support your head better."

Cons: "No meal option and my video screen volume did not work"

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

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: "Boarding was easy."
Cons: "I am 6' 1" tall and weigh 220, so not out of the ordinary and I felt like I was stuffed into a sardine can."

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

Pros: "great crew!"
Cons: "luggage. what a nightmare. I waited 30min for my luggage (after a delayed flight) only to be told by a fellow PASSENGER that some of our luggage was directed to a FRONTIER CAROUSEL. I then had to wait by that carousel till I found it. so much for "bags in 20min guaranteed""

Cons: "Better screens for in-flight movies. More legroom or upgrade options."

Pros: "Boarding was quick"
Cons: "No entertainment, plane was small"

Cons: "First delay notification: 1 hour 20 minutes 1 hour later, Second delay notification: 3 hours 15 minutes 2 hours later: Third delay notification: 3 hour 50 minutes Fourth delay notification: 4 hours 25 minutes Fifth delay notification: 4 hour 32 minutes No explanation for reason. Last time flying Delta."

Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."
Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."

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

Pros: "Everyone who has a kid knows how challenging certain things can be in a flight and for me the combination of a night flight interrupting my baby’sschedule + a full flight it equalized disaster. My daughter could not get comfortable for the love of life and I just felt horrible and frustrated and what sucked most was the 9 year old and her obese father siting in our row that kept giving us weird looks."
Cons: "There’s NO room in planes between seats. It’s 2018 and new planes must be done ASAP to accommodate people better. I’m 5’1” and 110 lbs but adding my 25lb daughter siting in my lap before she turns 2 is absurd to expect that it will be comfortable whatsoever for us or the people breathing next to us. Please DELTA, lead by example and make sure your planes are designed with more room in between and around the seats. In my opinion, every seat should be first class."

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."

Pros: "In a pinch they were able t"

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

Pros: "Everything was perfect !! Staff friendly"

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 entertainment unit allowed me to watch the Denver Broncos game live which helped lessen the delayed departure and uncomfortable seating."
Cons: "Uncomfortable seating....too crowded!! We had a delayed departure by 30-40 minutes because of a computer download issue. Too many folks carrying carry-ons delayed boarding. I wish folks were not encouraged to go that route but to check baggage. This time of year gets even tougher with folks carrying Christmas presents and over sized personal items. Ugh. Not fun to travel this time of year."

Pros: "App is good and convenient to use."
Cons: "The app went down just as we were getting ready to board and luckily i had a printed pass and it took some extra time to check in."

Cons: "We left late, it was delayed then maintenance issues. Twice. Seating was very tight and uncomfortable, no movies or entertainment at all. U.S. flights are the worst. Even on short flights with aeromexico outside the U.S. you get movies and food. Zero stars for comfort, food and entertainment."

Cons: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."

Pros: "The boarding process in Atlanta was as smooth as could be expected given that it was a full flight. I appreciated the gate announcer's suggestions to everyone about how to ease the overhead baggage crunch."
Cons: "Economy is very tight quarters."

Pros: "Friendliness of staff. Second flight was a newer plane - sweet!"
Cons: "For a long flight perhaps a little more in the snack department."

Cons: "Excellent service excellent pilot"

Pros: "Overall, the flight was very smooth and I thought the crew did a great job."
Cons: "I know this is a federal regulation, but I have to mention it as it is part of the boarding process. For the life of me, I can't understand why it is necessary to go through security again after re-entering the country. Understandable that I have to go through customs, but going through security again is ridiculous."

Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"

Pros: "Entertainment"
Cons: "This is my third flight this year with Delta and every time we wait for the "crew" to get off from another flight. And as soon as they get there we can board. It's getting very annoying. Fix it."

Pros: "Boarding was easy. Wifi was available and we got some snacks. Paid extra to sit in roomier coach, was worth it."
Cons: "Still pretty cramped, not the crews fault. Would've been better with the seat back screens"

Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"

Pros: "One male attendant from the first class cabin - super sweet and attentive to our needs even tho we're not seating in the premium cabin"
Cons: "Junior attendants in economy comfort seat - so lazy and whiny!"

Pros: "I appreciated the helpfulness of the crew."
Cons: "On the flight to Kansas City we had movie screens which spoiled me and made me think we would have them on the way back to Atlanta."

Pros: "Very professional and caring."

Pros: "plane had individual movies for free with each seat!"

Cons: "I've only experienced delayed flights with Delta ... and this was no exception. It wasn't weather-related, nor a late flight delivering a plane - just no ground crew to service the plane between flights."

Pros: "nice snack"

Cons: "We did not board at the scheduled time, although I believe we arrived on time. The crew was demeaning and singled out individuals who were causing the aircraft to not move. It was in a very pretentious manner, not like southwest personnel who have similar antics but with a playful tone. The plane is a small one where bags don't fit overhead and many head bumps occur. We arrived fine which mean the flight was successful but it was not very enjoyable."

Pros: "All went as planned and expected. No thrill- like taking a Greyhound bus in the old days...gets you where you are going but without much pizzazz New seats and quite clean, but the new seats were very hard and uncomfortable after an hour."
Cons: "Somewhat claustrophobic and always wish the drop down tray table behind could be disconnected from my seat. When the passenger behind uses the tray as a set of bongo drums to keep beat with his headphones it is a pretty miserable trip."

Cons: "I'm not sure how you lose a bag on a direct flight from Atlanta to Denver, but Delta found a way to do it. They didn't even put my bag on the plane and had to send it with the next one coming. To their credit, they did drive it out to my house when it got here."

Pros: "Crew was great."
Cons: "turbulence"

Cons: "IFE was not streaming movies, WiFi on but not loading"

Cons: "Spacing people out until this covid is over"

Cons: "No alcohol was available"

Pros: "The flight attendants were able to find a place for my carry-on luggage when the overhead bins were filling up. I got a seat with extra leg room by chance (without having to pay the extra fees)."
Cons: "There are no snacks served on the flight. The Philadelphia Airport was overcrowded. There was hardly any room to navigate and there was a long line at nearly every women's bathroom."

Pros: "Not using kayak."
Cons: "Worst flights in history. It took three days to get from Italy to the US. Do not use kayak!"

Pros: "It’s been a while since I’ve flown American, but the aircraft was updated with a solid multimedia system, great moving map, and a standard power plug and USB port at every seat. That’s more than I expected, and was quite happy. Service was solid—no complaints."
Cons: "Good & bad — flight arrived late, but the honestly, the pilots did their level best to make up the time and managed to arrive w/in 4 minutes of the scheduled arrival. Well done."

Pros: "Flight attendants very friendly"

Pros: "Nothing"
Cons: "When I spoke to the United person last week to confirm baggage and carry on requirements. He said I could take a carry on when I turned up to the gates I was charged another fee for my carry on bag. What is baffling is that when I arrived at Denver people were getting complementary check in baggage. I’m so dissatisfied with the booking and the amount it has now cost me ruining any savings I’d had for sanfrancisco"

Cons: "Crowded planes."

Pros: "The captain was wonderful"
Cons: "The crew were jerks"

Pros: "Boarded on time"
Cons: "Sat on tarmac in United plane at destination (Denver) from 2:40 pm to 3:35 pm. Waiting on a gate to unload...just long enough to miss my 3:30 pm United connecting flight. Why couldn’t United have delayed the connecting flight a few minutes knowing we were sitting in another of their planes just a few feet away?"

Pros: "Thanks for the free cocktail"

Cons: "More room space between seats"

Cons: "Not enough room!"

Pros: "Great flight! On time. Pleasant crew. Good snacks"
Cons: "Nothing"

Pros: "They knew of the issue and kept us on the plane for 2 hours before letting us deboard. The plane was 90 degrees and miserable."

Pros: "Easy to board friendly"
Cons: "The snack food selection, price on wifi"

Cons: "A passenger had to move because of an allergy to the "emotional support dog" in the seat next to her. They moved her before the rest of the flight had boarded, so the seating got messed up and took quite a bit of time to sort out. The flight crew seemed to be extremely put off by the whole scenario and couldn't seem to keep their displeasure professionally under control. I ended up volunteering to move because the passengers who caused the problem refused to bend. For all the crew's displeasure, they didn't handle the passengers, the passengers handled them."

Pros: "Got us here early, smooth ride"

Pros: "Coming home"

Cons: "No snacks...free"

Cons: "I'm 6'tall...NOT that tall and felt cramped the entire time."

Cons: "Return trip had small planes"

Pros: "This airline is better than most of the others."

Pros: "Love junction airport"
Cons: "DIA is always nice and kayak was a great service and price."

Pros: "When I got on the plane"
Cons: "Late by more then an hour and I missed my connection home. I had to stay the night in Denver and miss a day of work. This cost me an extra day and about $1000 worth of missed revenue."

Cons: "The fact that the tv is on constantly without the option to turn it off is annoying. The viewing length to passenger is too short to really enjoy (Probably not your fault). PLEASE permit us to turn it off."

Pros: "It eventually ended"
Cons: "Spent almost an hour before actually taking off. Terrible service. No"

Cons: "No TV"

Pros: "How fast they recovered my lost bag"

Cons: "Not 2 hour delay leaving."

Cons: "The flight left late, and got into San Diego late. By the time we landed I was unable to get my rental car. The car rental places were closed."

Pros: "The flight crew were Amazing on both flights. Seating was good on the 1St flight, I got the aisle seat, 2nd flight was little cramped “middle seat” I’m 6’3”. The flight was only and hour so not bad. Overall it was good."
Cons: "About 2more inches in the seating for long legged people taller than 5’8”. I’m 6’3”. So pretty cramped if not in an aisle seat."

Pros: "I did not like anything about this trip. The check in process was a pain. The boarding was chaos... (Of course, same 2 careless ladies were in charge."
Cons: "I did not like anything about this trip. The check in process was a pain. The boarding was chaos... (Of course, same 2 careless ladies were in charge)."

Cons: "Delayed with no reason which costed me more money as I didn’t get home until 3am"

Pros: "During the flood we had to go around the storm and camping was good to keep us informed of the status"
Cons: "The flight was delayed before we left and there was no update on the boarding area or on the app which is where I go to try to find out information is often difficult to maneuver with in the app.."

Pros: "crew is always resilient"
Cons: "Our plane was on time coming into Denver. We ended up changing gates due to another flight. Instructions for changes were not easily understood on the overhead. We ended up approx 1 hour late arriving in Salt Lake City. An additional cost of $20 was added to my shuttle as I was unable to claim bag until after 1 am."

Pros: "Very smooth flight"

Pros: "Staff was great. Baggage and service was handled well."

Pros: "Great flight"

Cons: "3hrs late"

Cons: "There was no flight. I was transferred to another airline by a frontier representative. That flight ended up being delayed as well."

Cons: "Charge you for everything!"

Cons: "Bags were lost by multiple passengers."

Cons: "Charged for every little thing"

Cons: "The check-in process didn't work and was confusing. Every time I tried to check a bag and pay the reduced fee, the website returned me to the window asking for username and password again. I could not check-in on line and had to pay full fee for checking my bag. I was frustrated and at the airport there was no consideration for giving me the reduced fee in light of the website malfunctions by the agent checking me in. Also, the steps during the check-in was confusing - trying to sell upgrades etc, instead of just taking you thru the check-in steps."

Cons: "That you have to pay for a carry on, and when I tried to go on line to pay for a carry on I couldn't find where to pay for it so I had to call frontier to pay over the phone"

Pros: "Cheap round trip tickets."
Cons: "Unreasonable delay time. Lost baggage. Mediocre customer service for the lost baggage."

Cons: "I will never ever buy a ticket through Frontier again. Worst airline ever."

Pros: "Nothing"
Cons: "Charging for baggage and not making it clear before buying tickets. Having to wait for baggage."

Cons: "The seats are so narrow.and leg room almost non-existent. I'm 5'4" and can't even imagine what it is like for taller folks."

Cons: "Too much nickle and diming. Website confusing"

Pros: "The crew was exceptional!! It was like booking a comedy club act in addition to the plane ticket. Made the run super enjoyable. Frontier fares would be worth the savings for me if available connections to the cities I need to visit were better & if I could check a bag at a reasonable cost. See my objections in other box."
Cons: "I still cannot get used to the lack of complimentary beverage during the flight - nor the fact that Frontier charges for carry-ons & tries to get me to "buy" a seat assignment when checking in on-line. Very deceptive web site. My principle dissatisfaction with airlines these days is being charged for every item they can possibly scrape an extra penny of profit from. Most people cannot manage a trip without some type of bag. If air fares reflected the savings, then the offset would be worth it - but most often that is not the case."

Pros: "The flights were on time."
Cons: "The seats were in comfortable. They charge for baggage whether you check or carry on. They don't send emails to allow check in by phone or computer if you buy your ticket on the internet. Bag check fees are too expensive. You have to pay for all beverages. When all things are considered, when the tickets cost the same amount, there's no reason to pick frontier."

Pros: "It was quick"
Cons: "The charge for carry on"

Pros: "The airline crew did a good job."
Cons: "First unexpected costs were not revealed at booking, price for the trip does not include your Carry-on bag. If you want to check in early there is a per seat charge otherwise it's assigned seating by them. We stood in line @ the Frontier counter to check baggage for 1 hour!!! It was understaffed and poorly organized. Then it took another half hour to get through TSA; not Frontiers fault. By the time we got to our gate we were already impatient to get it over with. Boarding was slow as many passengers with window seats came on last forcing a constant reshuffling of passengers. While the crew was competent, all the other problems made the flight very mediocre."

Pros: "MCI departure efficient"
Cons: "DIA tarmac delay, unable to get to gate"

Pros: "The steward staff and pilot tried to be comical and entertaining. That was fun."
Cons: "No offers for drink or snacks unless you pay for them. Charged for luggage to check and also charged for carry on. Charged for seats unless you wanted to wait until you got there and received poor seats. Charged for every little thing but couldn't even offer you a drink and a bag of chips. Flights delayed. Never again. I'll go with Delta or Southwest from now on."

Pros: "I paid for a better seat in the stretch seating and it was very comfortable with a lot more leg room."
Cons: "My flight to Kansas City was one hour late in leaving. No information was given to us about updates or why? My return to Denver was over 2 hours late. Once again, no updates or why? Southwest gives you peanuts, crackers and a free soft drink. You have to pay for everything on Frontier At the baggage claim we waited a long time. The information board showed our flight at #3. After a long time a passenger yelled to all of us, "hey, it is down here at a difference place.""

Cons: "Plane was an hour late. Then we waited an hour on the runway after we landed."

Pros: "Nothing"
Cons: "Everything. Very long flight delays, bad customer service, aggressive attitude of flight attendants, uncomfortable seats in the planes and hidden costs every step of the way."

Cons: "I had never flown on Frontier before. I selected Frontier because it offered the least expensive flight. I did not know that to get a seat I had to pay a fee for each leg of the trip. I also was not aware I needed to pay $30 to check a bag. In addition, I was not aware one could not even get water on the plane without paying for it. To top it off, 2 of the three bathrooms on the plane were inoperable."

Pros: "Comfortable seats for a little extra. No stress boarding. Reasonably friendly service."
Cons: "Very hard to see the "1" (ONE) when I check in, showing that I have already paid for one piece of checked luggage. The zero where I would add another luggage is in very large font. A bit confusing. On board service could be a little more professional with ongoing offers for service (pick up trash, offer free water) when seat belt light not on. Boarding area was a wee bit crowded in Kansas City."

Pros: "Friendly and couteous"
Cons: "How the seat selection goes, having to pay more to have a different selection"

Pros: "Simple boarding process, friendly crew."
Cons: "Paying for beverages? Ridiculous. I rarely fly Frontier (unless I have to) because they charge for everything."

Pros: "I liked the price that I paid for the ticket!"
Cons: "I didn't like having to pay for the bags checked or carry on, or the seat, soda, snacks, and anything else you might want."

Pros: "I slept on the flight and they only served drinks and cc applications"
Cons: "Took a long time to board and get off the flight. Our luggage took an hour to start coming into baggage claim. The staff barely said hi or bye to anyone or smiled."

Pros: "Its a quick flight"
Cons: "Boarding took longer than norm departing and arrival. They took away reclining seats and any type of entertainment. Not really like it used to be."

Cons: "Ticket counter attendant was rude and threatened me after asking about the carry on policy. A passenger was arrested and escorted off the flight and the turbulence was so bad someone threw up. The crew and pilot made no comment or even acknowledge either incident while boarding or while on the flight. I will never fly on Frontier Airlines again."

Pros: "Flight was on time, actually landed ahead of schedule."
Cons: "Had to wait on tarmac because gate was not ready. Did not know about high bag fees and fees on everything else. Had to wait for an hour after pulling into gate for luggage to get in. Seating very uncomfortable and could not adjust the backs. This was my first time on Frontier, will pay extra to not fly frontier again"

Pros: "Cheap flight"
Cons: "Extra charges for baggage"

Cons: "Seats. Fees associate with bags. Customer service"

Pros: "I didn't receive a smile or even an acknowledgement from flight attendents. Couldn't hear the safety speech at all. Annunciate and speak clearly would be my suggestion. This person sounded like they had a mouth full of mashed potatoes. I won't fly frontier again even though it used to be my preference. The baggage fee, not even a complimentary drink?? Uninterested staff. Very poor customer service. However, the pilot got us to destination on time and w/out mishap, hence my OK rating. Otherwise super disappointed in crew and staff."

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."

Pros: "Nothing"
Cons: "Customer service was rude. Seats were ironing boards with pleather covers, we were all especially jammed in. Airline crew was not pleasant. The best thing was when it was over."

Cons: "Being charged $45 to carry on a bag. Ridiculous."

Cons: "Delayed again longer then they said it would be as well, also their reason was "there's no good reason" awful"

Pros: "The flight departed on time and arrived as scheduled."
Cons: "I'm glad that I arrived safely because that is the one thing I can appreciate. The cheap fares equal the quality of the plane. Only 4 rows of 30 have reclining seats. It would be a stretch to say the seats are padded. The clientele is cheaper than the fare with lots of crying babes and impolite guests running to the door as the plane arrives to the gate."

Pros: "The take off and landing were perfect."
Cons: "The seats miserable and the little miniature trays were ridiculous. I didn't realize that you had to ask for water. the charge for carry on was equal to $60.00 and I had only two short trips although they were round trip."

Pros: "The boarding was fine, The flight was good."
Cons: "The baggage fees were ridiculous. especially carry on. And on such a short trip. I feel if you're flying on any airline one carry-on and one checked luggage per passenger should be free. Anything after that then charge for it. Especially for flights shorter than 2 hours. like ours from Denver Co. to Kansas City Mo. Unless you're traveling without any bags I guess it's pretty inexpensive. But that's unrealistic. I'll probably check other airline options as far as baggage. Cause this is a horrible way to treat passengers flying on your Airline."

Pros: "The spirit employees were very helpful when I checked in"

Pros: "They suck so bad!!!"
Cons: "They just suck really bad!!!"

Pros: "smooth"
Cons: "death do not recline"

Pros: "Got the row to myself"

Pros: "Raise ticket price and don't charge for first suitcase"

Pros: "Nothing"

Pros: "Planes were new and clean."
Cons: "Airport was disorganized. Check in was long and a mess at 8:30 in the evening. Long lines. Staff not helpful. No checkin kiosk to get bag tag. Probably will not fly Spirit again."

Pros: "O"
Cons: "BEFORE YOU GET ON THE PLANE SO MUCH EASIER ON DELTA I WILL NOT BE BACK"

Pros: "Like the convenience of the flights between Las Vegas and Denver. The ratings above you need to have a N/A for non applicable. We all know there's no entertainment. And the food is overpriced ! But"

Pros: "Nothing"
Cons: "Everything"

Cons: "Payment for drinks"

Pros: "Overall the web site looks like it was successfully intended to be attractive and it contains all the needed info."
Cons: "*Promising to answer a question "within 48hrs" is NOT OK when it is about checking in. *We SHOULD NOT have to register in order to be able to check in. Why is more than conf # and name needed unless it is to be shared or sold? *The needed info is scattered in many places on the site eg bag size, weight, and prices. *I was charged the "at checkin" price when I used the add baggage link before starting to check in; b/c I was within 24hrs? Purposely didn't start to check in yet so I wouldn't get the higher price."

Pros: "the service was wonderful, the l8nes wwnt by quickly"

Pros: "No frills or hassles"

Pros: "It was safe and fast"
