Cons: "The main economy seats were far too narrow."
Pros: "I always have a consistently good experience on Delta. Everything was great."

Cons: "New Flight crew."
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!"
Pros: "Nothing horrible service"
Cons: "Everything"
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: "The crew was great and super nice!"
Cons: "Screens with games, more leg room, and not having kids behind us messing with tray tables the whole flight."
Pros: "Not comfortable a little but scary on the flight to Detroit. Way better coming back to Denver"
Cons: "Better screens for in-flight movies. More legroom or upgrade options."
Pros: "Entertainment"
Cons: "Boarding at JFK.Always messy"
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: "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: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."
Pros: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"
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: "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: "Great in every way"
Pros: "Excellent piloting and cabin crew."

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."
Cons: "Both ATL-SGF and SGF-ATL flights got cancelled, requiring 2 overnight stays in Atlanta, including Christmas morning."
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: "free texting and entertainment!"
Cons: "our flight was delayed half an hour."
Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"
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: "Free in flight entertainment"
Cons: "One of my bags went to Santa Fe"
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."

Cons: "Junior attendants in economy comfort seat - so lazy and whiny!"

Pros: "Very professional and caring."

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: "American Airlies no longer partners with T-Mobile for free WiFi. :-("

Cons: "Old plane, no TVs"
Pros: "Jesus, the flight was phenomenal! He lightened up the atmosphere with his wit and grace."

Pros: "The crew was amazing - agreeing to work extra because it was Christmas eve and they wanted us all to get to our destinations for Christmas. They were very gracious and helpful."
Cons: "We were over an hour late to leave. I understand the reason for the delay because of weather. What I was disappointed in is that the delay was not announced until our actual scheduled time to leave. It meant people coming to pick me up didn't get the change information in a timely manner."
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: "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: "Flight crew had a great sense of humor - they were extra friendly while boarding as well, made traveling with AA the best! Boarding was delayed due to previous flight but our pilot even managed to get us to Denver early! Wish I could have this crew everywhere I go!"
Pros: "The onboard entertainment selection was excellent; great movie selection, wifi connection, and flight details. A winner! So much so that I chose to binge watch movies and not sleep!!"

Cons: "Too many people with carry on luggage."
Pros: "Wonderful flight.... great crew!"
Pros: "A quick flight between the two cities."
Cons: "After we all boarded the plane, there was an issue to be resolved. This meant we were stuck on the plane, mostly in our seats, for an hour before we took off. This meant there were numerous people on our flight who either missed or had to run to their next flights."

Cons: "Nothing could be improved for this short flight!"
Cons: "Delta Global Services is the contract company for UA and Delta in MISSOULA. After a great flight to MSO from Denver, we have been sitting in the plane while DGS tried to figure out how to get us off the plane. No management is here to make decisions. Horrible company that is managing United’s flight"
Pros: "The captain was wonderful"
Cons: "The crew were jerks"
Pros: "Fast n easy flight"
Cons: "It's still flying"
Pros: "Fast easy."
Cons: "Pricey."
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."
Pros: "Nothing."
Cons: "Delayed flights leading to incredibly tight connection times, staff inconsistent with messaging re the source of the delay, zero compassion for customers, offering $700-$1,400 to get off the plane when you charge $200 to change a flight 2 weeks in advance is especially galling! Will not fly with United again whenever there is a viable alternative to my destination."
Cons: "Our flight was delayed out of Mpls 2 hours so we had to rebook everything since we would miss our connection in Denver to Honolulu. The process of rebooking was terrible -- took almost 2 hours standing in line and the booking agent wasn't knowledgable Had to make an additional stop in LAX and arrived in Honolulu 5 hours later than we were supposed to. VERY disappointing experience all around!"

Cons: "I didn’t like all the excessive noise from the plane and kids."
Pros: "Flight was on-time; no delays; great crew! I also liked the fact there was a person at the gate to let us know where our connecting flight gate was - that was really helpful!"

Cons: "mechanical delays in Tokyo with only fair communication especially after we were in the plane."
Pros: "Crews were great, customer service was great! Rescheduled several times due to weather."

Cons: "The aircraft was full and they had a nonworking lavatory. And I asked the flight attendant that the lavatory was broken and he told me no there was somebody in there and he lied."
Cons: "An hour late which made me have to run to the next gate which is not pleasant for a 70 year old with a bum knee."
Pros: "a little bit more foot-room than my previous flight on a different airline."

Pros: "Staff was great, and the few delays that occurred were fairly minimal and it was clear that the staff/pilot did their best to keep things timely"

Pros: "Crew were friendly and helpful"
Cons: "Seats are tight, food is a few pretzels."
Pros: "Nothing. Horrible experience all around. Didn't get home till midnight"
Cons: "Kayak sent me a push notification saying flight was delayed. Arrived at airport, it was scheduled for on time. Airline wouldn't let me or my bag on the flight meaning I had to wait in the airport for 4 hours until the next flight out."
Pros: "On time. Comfortable"
Pros: "Efficient"
Cons: "Bumpy ride"
Pros: "The flight out went very well and the United staff were all friendly, very helpful individuals in all positions."

Pros: "The crew were pretty quick and responsive and the seats were pretty good."
Cons: "The dinner was alright but the breakfast was awful. The breakfast was the worst I ever had on a flight and the only thing I found edible were the little cookies that came with it. I had the omelette meal and it made me sick taking even one bite of it and the smell was pretty bad too."
Cons: "I think United is all about themselves and not the customer that group boarding is the worse and I travel first class and there was no food on the plane they had the nerve to announce it did not get a meal I do not think that is fair for $159 the company that I work for is about fifty of us and I will not be recommending any of them to you guys your special seats is only about who wants to pay for it like I said only about yourself United"
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: "After being delayed for 6 hours we ended up having our flight canceled due to the bathroom being occupied. Overall not satisfied with the service and will not fly with united again."

Pros: "The pilots"
Cons: "It's united."
Pros: "Movies were great. Crew was helpful but seemed flustered."

Cons: "Plane was late and missed connection to Wichita"
Pros: "Crew and staff were great!"
Cons: "Flight was delayed over 3 hours so we had to move to next day."
Cons: "I was charged $7 for the TV and it should have been $5 as my flight was less than 2 hours and the TV kept going out."
Pros: "Attractive staff very professional."
Cons: "No leg room and tight seats. Adequate but a tight fit. We travel with my husbands 72 lb lab seeing eye dog and we really needed a free area for him, but he was able to squeeze under. This was very uncomfortable for us. They offered the aisle row person a chance for another seat in the rear, which of course was declined and I can't fault her."
Pros: "Ended up buying a flight on American Airlines, will never fly United again. God help you if you have a disability!"
Cons: "I was kicked off the plane for telling the flight attendant as I have a 1000 times that I have anxiety while flying. She said I'm not risking our flight. Tried getting a refund and have not! The airline is trying to say I never made the flight! I took AA first class and guess what. Best expierence so far!"
Pros: "On time, friendly crew, bags got through timely"
Cons: "Nothing in particular."
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."
Pros: "We were upgraded to first class on our connecting flight and my husband and i sat together. That made up for the first flight, because our seating separated us three, which I didn't like."
Cons: "Delayed flight to Denver and our seats were not together."
Pros: "Basically good, except for delay."
Cons: "45 minutes to go 64 gates to catch my flight to smf is too tight. Flight was a few minutes late. Carry on was too for crj. Went as quickly as I could and arrived at time that aircraft door was scheduled to be closed. Flight delayed 45 minutes due to late equipment arrival. Never saw a sign telling me of the gate for my flight."
Pros: "Good flight attendants."
Cons: "Nothing"
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: "WiFi was awesome"
Cons: "Wish the TV preview was continuous & pay for movies but watch regular TV work no charge"
Pros: "Got to check 2 carry on pieces for free because too many people had carry on bags. We had paid to check one bag and would have to pick it up anyway, so checking extra pieces was not a problem and actually was very much appreciated."
Cons: "15 minutes late in taking off because an airline associate failed to close out a screen on the computer. It took too long to figure out the problem."
Pros: "The staff was nice"
Cons: "There isn't anything I would say that I didn't like. I just would have to say it was overall a good experience"
Pros: "nothing"
Cons: "Not 2 hour delay leaving."
Pros: "The flight was short"
Cons: "I absolutely HATE aisle seats. The crew brush pass you putting all of there private body parts on you and they will absolutely run over you with that metal cart. It’s so unprofessional. They brush pass you with their butts, crouch area, and hands all over you. Awful experience"
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: "The flight out of MCI was delayed... no employee appeared before the actual loading time..so no one knew what was happening until it was time to Board. When the agents finally arrived they seemed very “disorganized” and confused and did a poor job explaining the delay... and once the gate change was"
Cons: "Continuing... was announced they were rude about explaining the gate change, then no one was at the new gate, was a chaotic mess off people all crowding trying to board, the agent yelled “GET IN ONE LINE!” as if we were all idiots... plane was uncomfortable... I stood up to use the restroom, and a"
Cons: "No cost for carry on bag"
Cons: "Frontier seats are very uncomfortable"
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: "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: "The price."
Cons: "Uncomfortable non-reclining seats, inconsistent delay notifications, no audio or visual options on flight."
Pros: "Very smooth flight"

Pros: "Staff was great. Baggage and service was handled well."
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: "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."
Pros: "Cheap round trip tickets."
Cons: "Unreasonable delay time. Lost baggage. Mediocre customer service for the lost baggage."
Cons: "Scariest plane ride ever, the pilot landed terrible, I don't even know how to explain it. So much stress we practically nose dived, it was like they realized "dang we have to land, I forgot about that, let's go straight down and almost crash""
Cons: "Seats were about 1.5" thick plastic, rigid, with no padding. Felt like a military transport. Advertised as the cheapest fare, but with the luggage addon for carryon and checked - was not the cheapest"
Pros: "Flight was on time!"
Cons: "How we don't get a free luggage. Like who travels without a suitcase?"
Cons: "The only bright spot was your great crew. First, Frontier doesn't even staff its ticket counter at MCI, so, heaven forbid there's an accident on the highway and we're a couple of minutes late, we can't even get through security. That's beyond annoying. Frontier charges for everything. For seats. For bags. For drinks. For food. So, after a haphazard boarding process and ending up in a middle seat, I flew on a lawn chair. Thankfully, it was a short flight. I enjoyed a tiny cup of water and opted not to spend $2.99 on another beverage. All of that, I knew about in advance and expected. I was thinking "at least my flight was cheap..." At the end, Southwest would have even been cheaper. I also didn't realize Frontier couldn't even be bothered by the basics. For example, opening the door when we arrived in Denver. We were on time. We waited on a gate, which is annoying, but not unusual, but then, after we pulled up to the gate, we waited ANOTHER 15-20 minutes in a roasting hot plane. JUST for someone to open the door to permit us to deplane. One of my fellow passengers quipped: "Are they going to make us pay to get off the plane?" Funny, sarcastic, but a sentiment many of your passengers shared. We finally exited the plane, and I waited on my bags--the ones I'd spent $75 to check. There was no information. No announcement. No update. The supervisor truly didn't even know what was going on. An HOUR AND A HALF later, the supervisor said, "I think your bags are still on the plane. We're short staffed, so another supervisor and I will go help unload them" Seriously? At what point did unloading bags become optional? We finally got our bags, and I'm the one who finally told the supervisor that bags from Kansas City were beginning to arrive. She announced it to the rest of the grumpy crowd. It was much worse with the cranky kids waiting on their strollers and carseats. I fly this route often. I arrived home AFTER I usually do on the much later Southwest and United flights. My fiance and I are traveling back and forth DEN-MCI/MCI-Denver often. We no longer even look at Frontier as an option when booking our tickets"
Pros: "Nothing"
Cons: "Charging for baggage and not making it clear before buying tickets. Having to wait for baggage."
Cons: "Too much nickle and diming. Website confusing"
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"
Cons: "They changed their seats, less room, less comfortable, tray tables are tiny, they nit pick and charge for EVERYTHING. They purport to be a discount airline, but in reality they're just a money-grubbing company who nickels and dimes their customers while providing a much worse product than they did before. I will not be flying Frontier ever again."
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."
Cons: "Both flights were very late. No TSA pre-check. Baggage claim was a total NIGHTMARE. Half of flights luggage showed up on carousels that were wrong. Agent in baggage claim kept apologizing for delays and bags on wrong carousels. She was ready to have a stroke. Bet she quit today. No options to pick own seats unless you paid more for the seats."
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.""
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."
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: "Generally cheap flights and always fast flights to denver."
Cons: "No complimentary drinks or snacks with the flight which pretty much every other airline offers. The new seats are not very comfortable. The tray table is a joke for how small it is."
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"
Cons: "Uncomfortable seats, drinks aren't complimentary, paying for carry on luggage"
Cons: "Seats. Fees associate with bags. Customer service"
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: "I didn't like the terrible turbulence which we had on May26th. I know that was not the airlines fault, but it seemed excessive to be on the tarmac for over 2 hours and being over three hours late in getting to the gate. It was the airlines fault that I had to pay $40.00 to check a small bag and that we only got a half cup of water after the long delay."
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: "Good price"
Cons: "MCI in Kansas City is an awful airport. The seats on the flight had less leg room than most airlines. No free snacks, drinks, etc. Those for purchase outrageously priced."
Cons: "Unannounced baggage charges and reserved seat charges - they charge for carry on bags; are you kidding me?"
Cons: "Horrible airline. But I knew that. Didn’t have much choice on short notice. I avoid this airline as much as humanly possible."
Pros: "It is a discount airline - and a good performer in that mix."
Cons: "I am not a big fan of the nickle and dimeapproach."
Cons: "Being stopped when I was boarding and notified that I had to pay an additional $65 to carry a bag on the plane was frustrating."
Cons: "I have been taking this flight every week for the past month. Have taken off late and have spent a median of 20 to 30 min stuck, at a full stop, on the runway before deplaning EVERY SINGLE TIME. Unbelievable."
Pros: "The airport, before I got onto my flight. I'm glad spirit allowed me extra time to spend in the airport after the flight was delayed. Surprise."
Cons: "All of it. What was advertised: cheap seats and you pay for everything (checked bag and even WATER). What wasn't advertised (or was, in flight): for fifteen+ minutes the crew was selling a spirit credit card over the intercom. BLARING IT. It woke me up. Why sell more things where your prospective customers can't escape listening to the sales pitch? Terrible terrible business."
Cons: "will never use this airline again."
Pros: "The low initial ticket price"
Cons: "Having to pay for a seat and baggage after buying a ticket. I got an earlier standby Delta flight on Friday so I skipped the first Spirit flight (which ended up being delayed anyway). On my flight back to Denver today, I found out in the terminal that my entire trip was cancelled because I missed my original outgoing flight. I was never notified of this cancellation through email or phone call. I was then asked to pay another $200 for a one way ticket back to Denver. Luckily I was able to fly standby on Delta again instead. Never flying Spirit again. Terrible customer service as well."
Cons: "Spirit airlines cancelled my flight the day of travel."
Pros: "Nothing. I was treated so poorly I walked away from their customer service and bought a ticket on another airline."
Cons: "I was 5 minutes late over their 45 minute required check in window. So they cancelled my ticket. For $100 they offered to reschedule me. And for another $50 they would check my bag. On a different airline I paid another $100 and got a complete round trip ticket, about 10 minutes later."
Pros: "The crew was very pleasant"
Cons: "Boarding was messy. The seats were extra cramped. The crew pushed their company credit card very hard which became annoying. The airline nickles and dimes you for everything."
Cons: "Charge for everything"
Pros: "Nothing except the price"
Cons: "Delayed boarding"
Pros: "The boarding process was good. T The staff friendly, but should smile!!"
Cons: "The seats were uncomfortable."
Pros: "Nothing"
Cons: "They cancelled my flight 24 hours before, and I had to buy a last minute ticket on another airline."
Pros: "Nothing. I missed it because of the delay in the first flight and ended up on American airlines"
Cons: "Everything. Spirit sucks."
Cons: "This airline company was totally misleading about everything. My luggage was okay on one flight but return flight was not okay, had to pay for luggage both ways. Was told to check in on line and the website wouldn't let you plus then had to stand in line for 45 min to check in only 2 clerks working with 109 plus people in line. I will not fly spirit again. The seats where so small and uncomfortable."
Pros: "cheap fares"
Cons: "3 dollars for a Coke"
Cons: "I spent money on the cab to the airport only to be turned away because spirit canceled the flight. They told me my money would be returned but I have not seen anything yet."
Pros: "Crew was friendly and knowledgeable"
Cons: "Felt like after paying all the fees we could have just flown a regular airline"
Pros: "I liked the stewardess coming back to denver she was nice and beautiful"
Cons: "Seats are uncomfortable"
Cons: "it was awful - I can't believe how narrow the rows are. I'm 5'5" and my knees touched the seat in front of me. A third of my personal item (a backpack) stuck out from below the seat in front of me. I've never been more uncomfortable on a plane. But it was cheap, so...worth it?"
Pros: "Missed flight! Got delayed and they never called us and we were at the gate area. Spirit is terrible."
Pros: "Nothing to brag about."
Cons: "Lack of space, over charged for baggage, delays on both ends of the trip."
Pros: "Nothing."
Cons: "Delayed twice, seats do not recline, no snacks included, they charge for carry ons. They are the worst airline. Period."
Pros: "Chose Spirit because of price and received what I paid for, a safe trip to Las Vegas. Nothing more nothing less. Flight was in time."
Cons: "Should not complain because price was prime consideration but the legroom was minimal (I'm barely 6ft tall), and the seats were hard."
Pros: "It's a plane. It was a short flight- all was fine. It was cheap, and I didn't need any baggage, so Spirit is the best airline for that. You can't beat the price. Booked the night before- about 16 hours before the flight."
Pros: "NOTHING"
Cons: "Everything with spirit is terrible. The trick prices (you think it's cheap??? Not if you want a seat, a bag, a drink, to breathe!!), the terrifying folding chair seats, the horrible leg room, the worst service. Now I remember why I NEVER should EVER fly spirit."
Pros: "Good Equipment, Airbus 319. Prompt take off and on time landing, both directions. Good fares, but a little tricky on the baggage. Assigned seating... even though we went with assigned seating, we still got to sit together, both directions! All issues considered, I would fly Spirit again, and I will encourage others to do so as well! Patrick"
Cons: "Had an issue paying extra for the baggage. Even though my credit is excellent, my card was rejected, so I had to call a rep from Spirit to make arrangements on the same card. This took an hour and a half on the computer... who knows why? Once I spoke w/ the rep, it was wrapped up in 10 minutes. Patrick"
Pros: "Crew was pleasant and helpful."
Cons: "The extra charges to actually use the ticket came to more than the flight."
Pros: "Clean airline. Nice staff."
Cons: "Very little leg room."
Cons: "Misleading information about charges for carry-on. I understood extra charges would apply to luggage checked in, not suitcases carried onboard. Leg room is too small for tall people. I am 6'1" and my knee's were pressed against the seat in front of me the whole trip, not comfortable at all."
Pros: "Met some pretty cool people in the seats next to us. Bathrooms were clean, easy to use, and easy to access. They had a bathroom light viable to all passengers to see whether or not they were occupied for all 3 bathrooms, which I really appreciated."
Cons: "My only complaint was that during our layover in Chicago we couldn't get off of the plane to get food. Eventually we just bought food on the flight because our trip in total was about 6 hours of flying. I wish there was more food options. Oh, and the crying baby behind us wasn't the best either, but we drowned it out with conversation."
Pros: "Since we couldn't get passes in advance the clerk gave us leg room seats"
Cons: "The online program was horrible. Couldn't print boarding passes in advance"
Pros: "I arrive safe"
Cons: "I spend more with my luggage than fare it was not disclose Not even water or snack"
Pros: "I liked the crew"
Cons: "I did not like that my flight kept getting delayed and they provided late notifications"
Pros: "The check in process, boarding process and the flight were smooth."
Cons: "The boarding pass that we downloaded on our phone weren't valid. After waiting 20min for security clearance, we had to go back and get the boarding pass from the kiosk. Spirit should have mentioned ahead of time that mobile boarding passes don't work."
Pros: "Nothing"
Cons: "Seems like a cheap ticket until you factor in all the extra charges. Carry on bag $50, water and a snack $10. I'm surprised the bathroom was still free of charge. The captain couldn't get one of the engines started but taxied out to the runway anyway. When it still wouldn't start we turned around and went back to the gate to wait for a mechanic. They were able to get it started and we were able to fly."
Pros: "I had flight delay for 6 hrs, missed my business meeting Las Vegas ! Very rude people at Spirit counter, never will consider Spirit as my 1 suggestion! All this and I paid 1st class accommodation, I really think I should be compensated! 7194600011 thnx! Reg!"
Pros: "Absolutely nothing"
Cons: "They nickel and dime you to death. Just horrible. The ghetto of airlines"
Pros: "Play was very clean people were very good flight left on time arrival time packages were there on time just overall I had a great time"
Pros: "Worst flight i have ever been on"
Cons: "i will never book with them again"
Cons: "they charge you for everything. They say they are making you a deal by giving you a cheap flight. but charge you for carry on and personal items. and charge you $4for a tiny water.They are a bunch of A-hole. And I will never use spirit again"
Pros: "Price. Personably flight crew."
Cons: "The seats were very uncomfortable. I think my personal maximum time for a flight with those seats is 2 hours or less. 4 hours nonstop was too much for me."
Pros: "Nothing"
Pros: "The price of the flight is hard to beat. I can live without the seats reclining and a free soda."
Cons: "Pay attention when buying your ticket. There are extra fees like paying for the seat you want or for checked bags."
Pros: "the flight crew"
Cons: "how late we were to board, almost 3 hour wait to fly to vegas, seats were uncomfortable."
Pros: "Effecient boarding. No overly comedic routines from staff to include pilots. On time."
Cons: "$55 for a carryon bag."
Pros: "boarding was quick"
Cons: "The counter lady said my luggage was to big. It is the same bag I used on the previous flight with Spirit. WE walked out there and put it in the luggage sizer and it fit. she never left the counter she just yelled. I don't think so. so we had her come out and look. Customer service is lacking."
Cons: "On the sight online does not tell you that you have to pay for each baggage $50 dollars people should know that! !!!!so they would not be surprise .At cheking in my parents the lady wasn't as nice just because we didn't know that we have to check in on one of the machines! !!!not a good experience!"
