Scores according to KAYAK customer reviews

Cons: "Wouldn’t change a thing! I don’t always fly! But when I do!! I fly delta!!"
Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."
Pros: "I always have a consistently good experience on Delta. Everything was great."
Pros: "Everything ok. I was hoping to buy food but glad to see almonds as one of the free snacks. Delta seems to be upping its game a bit lately."
Cons: "No US carrier seems able to master smooth boarding without standing waits."
Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"
Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."
Cons: "1.5 hour delay...no reason given!"
Cons: "Flight was delayed and completely packed so our family could not get seats together"
Pros: "Love the fact that the head rests move to support your head better."
Pros: "The male crew member was excellent. He was responsive and speedy with trying to find a solution. He gave me a few flyer miles for my trouble and was empathetic, which is rare."
Cons: "The tv/monitor didn’t work so there wasn’t any entertainment for the majority of the flight."
Cons: "No meal option and my video screen volume did not work"
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."
Cons: "Better screens for in-flight movies. More legroom or upgrade options."
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."
Pros: "Overall experience"
Cons: "Very little leg room."
Pros: "JFK to Denver the flight Attendants were once again great. Lots of entertainment choices again. The usual rough air coming into DIA."
Cons: "From JFK to Denver the seats were to close for leg room by an inch or two. The temperature was hot most of the flight."
Pros: "Love the built in tv’s with free entertainment."
Cons: "The plane got delayed on the runway and the shut the engines off so the plane got super hot, but even after we got up in the air it never cooled down. Normally I’m freezing on flights, but I just sat sweating this whole flight. It was terrible."
Pros: "The seats had plenty of leg room and the crew was was very kind."
Cons: "My seat was uncomfortable and I was seated in the only row of the aircraft without entertainment for a four hour flight. Then on top of that the passenger next to me removed his shoes and you could smell his feet from a mile away but the flight attendants never requested for him to replace his shoes."
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: "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"
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: "Nice enough crew"
Cons: "The MD88 is such a crappy plane for anyone that wasn't born a dwarf. I'm tired of filling out these and yet you do nothing about it. It is criminal to cram is in like sardines like this."
Pros: "Great in every way"
Pros: "Excellent piloting and cabin crew."
Pros: "It got me home, eventually."
Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"
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: "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: "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: "The plane was really nice, food was good. I had a pleasant time."
Pros: "really helpful and friendly service and nice seats."
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."
Pros: "The plane, crew was clean, newer and had TV's in the backrests. Remember to bring headphones! Seats are tight, but the crew was friendly and may the flight experience positive."
Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"
Cons: "Excellent service excellent pilot"
Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"
Pros: "Free in flight entertainment"
Cons: "One of my bags went to Santa Fe"
Cons: "I'm tired of Delta making it IMPOSSIBLE to experience benefits of my loyalty. I flew literally AROUND the world in the past 6 months and it STILL doesn't qualify me for anything more than Silver elite? Seriously? When you use a voucher because of their error to lower your ticket price, but still pay cash for it, why does that then automatically exclude you from upgrades? Poor customer loyalty, in fact, non-existent these days."
Pros: "Early arrival. And service"
Cons: "I was assigned very last seat and there is no reclining option."
Cons: "long wait and delayed flight"
Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"

Cons: "Junior attendants in economy comfort seat - so lazy and whiny!"
Pros: "The price, until you lied about that!"
Cons: "An additional 70.00 in baggage for Roundtrip that is not disclosed until you check in...BS. delays, delays, and more delays!"
Cons: "6/11/2016- stuck on Tarmac for no reason for over an hour. Missed last shuttle to Boulder due to waiting on luggage at baggage claim for another 2 hrs. Unacceptable!!!"
Pros: "Everyone was very helpful"
Cons: "No beverage"
Pros: "Price point, comfortable seat."
Cons: "No entertainment options"
Pros: "Honestly, I can't think of one thing I really like. The restrooms were clean..."
Cons: "I felt the check in process on the website was misleading. I had to read multiple times for carrying on my bag, and ended up paying $30 because I thought if I didn't pay while checking in on line that I would end up paying $60 at the gate to carry on."
Pros: "Everything went fairly smooth. The safety speech was clever."
Cons: "Paying for beverages."
Pros: "The ease of boarding. The staff was friendly. Better than AA"
Cons: "The drinks and snacks aren't complimentary anymore?! I asked for juice and was charged $2.00, it's just sad and outrageous; the inflation of prices."
Pros: "All conduct was very good."
Cons: "No food, no tv, no magazines"
Pros: "I find it unbelievable that Frontier could Fly in and Out of Denver under severe Blizzard like conditions."
Cons: "That you didn't cancel, while 800 plus flights were canceled and Frontier chose to Fly In It and Out of it."
Cons: "Should at least offer water(for free) to passengers"
Pros: "Chairs don't recline. Bags sent to wrong claim area. No leg room. Plane was freezing."
Pros: "I felt safe throughout the whole trip; the landing was on if the smoothest landings I've felt ever. Frontier is the only airline I have taken."
Cons: "Frontier charges for carry ons. Ridiculous!"
Cons: "Being nickeled and dimed to death."
Cons: "The price of beverages/food."
Pros: "Cheap fares"
Cons: "Squished in like sardines."
Pros: "Staff need to communicate. Misinformation and now luggage is missing after we were delayed in des Moines for hours."
Cons: "I provided my frequent flyer number. You did not provide me TSA Pre-Check ticket. (My frequent traveler number is a TSA Pre-check number)"
Pros: "The flights didn't cost too much."
Cons: "They charge for anything they can."
Cons: "Frontier airlines as a whole is not worth the money"
Pros: "Everyone was courteous."
Cons: "Did not know that a carry on cost extra money. No complimentary drinks. Wish things had been more upfront when ticket was bought."
Cons: "Bad service"
Pros: "Helpful employees"
Pros: "We had the nicest stewardess that I think I've ever had."
Cons: "The checkin lines were extremely long despite pre-checking."
Pros: "I enjoyed the speed of boarding and organization."
Cons: "I don't like the price of the food it's a little to over priced."
Pros: "The captain and stewardess were very nice and accommodating."
Cons: "The plane was very very dirty. It hadn't been cleaned in quite a while."
Cons: "I have back problems and the seat did not lean back which helps relieve discomfort"
Cons: "I was unaware Frontier had gone the ultra economy route like Spirit and started charging for Carry On and printing boarding passes. Should be disclosed up front, not after purchase."
Cons: "Didn't like the "surprise" baggage & carry-on fees."
Pros: "Paying for a carry on and no complimentary drinks just water"
Cons: "Very tight space and super uncomfortable chairs--no cushion and don't even lean back."
Cons: "I'm not happy that I wasn't notified in advance that there would be an added $40 per bag. When flying with other airlines usually one bag and carry on is included in the price. I am not happy that upon arival I was notified my one bag would be an extra $40. That should have been discussed before."
Cons: "bag fees and slow boarding"
Pros: "The price. I did not like the hard seat, the cramped row, the staff selling booze to those around me and watching them get drunk, the loud noise of the engine, the feeling of being like a sardine in a small can, being held once we boarded for a maintence issue for 50 minutes. It is no longer enjoyable flying. All most of the U.S airlines care about is their profits...the bottom line."
Cons: "See all of above."
Pros: "Great price though."
Cons: "Comfort is horrific, food and drinks you have to pay for... Really bad."
Pros: "Smooth landing."
Cons: "The added charges for my self contained firearms."
Pros: "attendants were helpful and friendly"
Cons: "would like some reading materials since they don't have entertainment anymore."
Cons: "Carry on charge, and the web site is a mess, will not allow seating or registration. Required to go to the airport to complete. It kept take e back to the home page."
Cons: "I specifically searched for IAD (Dulles) and you returned results for DCA (Reagan) I think you need to have some type of confirmation window so that people realize that you have switched airports on them."
Pros: "Arrived 15 min Early"
Pros: "nice service and don't tying wrong customer information!"
Pros: "All was good!"
Cons: "The representative at the gate was rude and unpleasant."
Pros: "The plane was clean, and we arrived early on each leg of the trip by about half an hour, the staff were kind. Frontier does charge for bags either checked or carry on, and it was cheaper for us to check one bag rather than each carry on. I knew frontier charged for bags having flew with them a few times, so that wasn't unexpected. True it's not a first class experience, but it was exactly what I'd expect from a budget carrier, I got to my destination early and without hassles and that's really all I was looking for."
Cons: "Baggage fee info on site makes me feel that i have to pay for every carry on even small bag"
Cons: "Don't like the carry on fee!! Just put it in the cost of the ticket. Charging for a cup of coffee? Lame!"
Pros: "I don't usually even do reviews but since flying with Frontier from many places. But being military and flying from multiple cities and going with Frontier I have experience super cheap tickets through other websites, quick check ins, free baggage because I am military and non-stop flights that have great take off and arrival times. Frontier is my favorite out of the many other airlines I have taken."
Cons: "Very uncomfortable ride. We a t-shirt hard ,zero leg room"
Pros: "They suck so bad!!!"
Cons: "They just suck really bad!!!"
Cons: "The $100 carry on fee at the gate... It's a carry on!"
Cons: "death do not recline"
Cons: "Trying to get a boarding pass electronically was one of the most painful experiences I've had this year. Never again."
Pros: "Got the row to myself"
Cons: "Small chairs"
Cons: "Why ask for a ratING on food and entertainment that don't exist?"
Cons: "The plane was delayed! They have all these secret fees"
Pros: "Cheap tickets"
Cons: "Everything has a price. I don't have across on my return to print a boarding pass before I get to airport so now I have to pay $10 to PRINT a boarding pass from a kiosk. Come on, really... $10 bucks?!"
Cons: "There should be a very clear notification of the bag fee cost and a way to prepay that is also simple."
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"
Cons: "See above answer"
Pros: "It's always the cheapest option."
Cons: "...well not always. I am accustomed to flying these two airlines that share the same model. Fly with one small backpack."
Pros: "Needs more room. Packed like sardines"
Pros: "Good seat, enough room"
Cons: "Cost for food"
Cons: "Fees, late arrival"
Pros: "Price was good. i ]will fly Spirit whenever possible and I will rnecomend often"

Pros: "Everything was good"
Pros: "Not crashing"
Cons: "Late schedule, last bags, rude airport personnel"
Cons: "Did not do final leg"
Pros: "I liked that I eventually made it back to Denver"
Cons: "The fact that the delay was all based on Spirit not being able to properly maintain their aircrafts and gates. The hour and a half delay that ultimately made me late to work the next day was not even due to weather issues. I blame spirit for the inconvenience and this will certainly effect my future decisions to fly with spirit."
Pros: "We made it to our destination."
Cons: "My luggage was lost and I'm without any belongings for myself or my 1 yr old baby!"
Pros: "I liked the bundle prices on drinks."
Cons: "No monitors behind seat headrests or wifi and arm rests became very uncomfortable"
Cons: "I was not informed of the 45 min check in cut off, and so Lost hundreds of dollars. I will never use your site again."
Cons: "So late!"
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"
Cons: "There was a rotten banana peel stuffed in the pouch in front of my seat, and it smelled really bad."

Cons: "The baggage charges are ridiculous. Couldn't believe them. Won't be flying on this airlines again soon."
Cons: "Spirit airlines employees are not friendly and difficult to deal with. Were not accommodating"
Cons: "False advertising regarding rates. Price doubled after mandatory items charged. Doesn't reflect what search claims price will be."
Pros: "Nothing, although the air was breathable, so could have been worse"
Cons: "Bag charges thru the roof, charge for coffee (that tasted terrible as well), ticket change policies, etc, etc"
Pros: "Quick k and easy."
Cons: "Late and delayed constantly"
