Pros: "I really liked American Airlines and delta for picking up the slack for United"
Cons: "We could have got on 1 United flight. Every flight by United was either canceled or delayed to the point that forced us to miss our connection. Out of 4 originally booked United flights we made zero. We had to be out on delta and American to make our trip happen. Never again United"

Pros: "I really liked American Airlines and delta for picking up the slack for United"
Cons: "We could have got on 1 United flight. Every flight by United was either canceled or delayed to the point that forced us to miss our connection. Out of 4 originally booked United flights we made zero. We had to be out on delta and American to make our trip happen. Never again United"
Pros: "The cabin temperature was hot before and during the flight."
Cons: "Cabin temp."
Cons: "We turned around mid flight and had to come back to Houston :( we stayed at a holiday inn and didn’t get another flight out for 24 hours."
Cons: "bad"
Pros: "Flight crew was great, seats were great."
Cons: "Checking in was a nightmare with rude and nonchalant United agents who seemed oblivious to the late/canceled flights pandemonium with passengers scrambling to get questions answered about the rebooking possibilities being offered. I got a text message at 4:30AM about delay and rebooking opp."
Cons: "Dang the seats are just small in the coach area. Great smooth flight and my bag arrived where it was supposed to be. Cant complain there"
Pros: "Amazing job get my canceled flight reschedule for my nanny memorial. It was amazing helpful staff!"
Cons: "Way to fix flight after it cancelled"
Pros: "Crew and staff were professional."
Cons: "3.5 hour mechanical delay with no offer for a meal voucher or complimentary snack or drink when flight finally took off."
Pros: "Staff was all friendly and exhibited positive and helpful attitudes. I also think the price and route was an excellent deal for this flight. It was actually such a good deal, it’s the main reason I even went."
Cons: "I think the baggage restrictions thing is really slimey and a shameful scam. I actually wouldn’t have minded paying around $50 more for my ticket and hand the bag included than be misled into thinking I could take luggage and finding out after it’s too late that I have to pay for my luggage. I think it’s a really sleazy business tactic (akin to resort fees). Fortunately for me however, I don’t travel with luggage so it doesn’t directly affect me. Still think it’s. Shitty way to do business though."
Pros: "Great staff and flight overall"
Cons: "Delayed 40+ minutes resulting in missing next flight. Stood in customer service line for 3 hours only to realize no meal or hotel vouchers provided aside from a discount provided by United for hotel booking."
Pros: "Nothing"
Cons: "Never made it. Stuck in Denver."
Cons: "Flight was cancelled on our way back home from Gudalajara, was speaking to a representative for almost 2 hours to get me on the next flight the flight representative forgot to put me on hold and told everyone how rude i was, i was not rude i was just trying to get home. The representative couldn’t help me so i asked to be transferred to a manager, after 2 hours i was transferred and the manager hung the phone up. Long story short i called back spoke to another manager Yana and she was the rudest lady ever! She basically told me for waiting to long i will have to be placed on a flight 2 days after my cancellation flight. I started to cry because i needed to be home and she basically did not care so i took the date. Never again and i will warn everyone about this airline and their customer service!"
Pros: "I purchased a ticket for my 18 year old dog $ 125.00 each way to fly with me to Kalispell and back. She is so old that she can not SEE, HEAR, or BARK any longer. I understood she needed to be under the seat for take off and landing but I was told by the ticket agent and flight attendants on my first flight that she could sit on my lap during the flight. Everything was great on the way there. On the returning flight,.... the flight attendant was so RUDE to me. She saw that after we were airborne and at a steady altitude, I brought my dog "Kacey" up into my lap. She immediately raised her voice and stated the dog needed to remain on the ground. I politely explained her condition BUT she refused to listen to anything. I put my poor old dog back under the seat. After approx 20 min I could hear her patting very loud. I lifted her again and asked a different flight attendant for some water. She was very hot on the floor. Or course, the flight attendant saw my little chihuahua drinking the water and said that after she drinks a little more, she must remain under the seat. By now, my husband is getting annoyed. He tried explaining to the flight attendant the medical needs that my dog has " she's on protein shakes" which were approved their security. and how fragile she is. She can't BARK, SEE, or HEAR. Yes, we will be putting her down soon but we took her to Montana for my daughter to say her GOODBYES!! Sorry to say, but that flight attendant has turned me away from UNITED AIR LINES forever. Feel free to call me 352-804-8344. You may send this to UNITED AIRLINES too!! Thanks Karen Hope"
Pros: "We got to our destination."
Cons: "I am not a large person and yet I felt squeezed. There isn’t enough room to get out of one’s seat even when everyone in the aisle vacates."
Cons: "As usual, United manged to mess up something new and different. This time, they couldn't get the plane towed from the hangar to the gate in time for an on time departure. The ground staff was even annoyed by this development, and the plane finally appeared about the time we were supposed to be leaving. To their credit, the gate staff tried to keep getting updates and passing them along, but had little luck. Fortunately I did not miss my connection in Houston but I'm not sure the same was true for everybody. When we arrived, we sat for 10 minutes waiting for our gate to open, which the crew interestingly blamed on the delays caused by the rain. Funny, the only delayed flight on the screens in the terminal was odd ours. The rest of my trip was flawless. I'm sorry for Air New Zealand that they have to rely on United to gather passengers for them in the USA."
Cons: "No beverage offered during the entire flight. Plane was on the runway for about 40 min prior to take-off. What a waste of time!"
Pros: "Fast flight"
Cons: "Small chair"
Pros: "Economy plus comfort"
Cons: "Paying extra for economy plus. One and one half hours late."
Cons: "We booked what was labeled a Lufthansa flight and paid extra because we had flown Lufthansa before and thought the service and the flight were excellent. Imagine our surprise when we found out it was a United Flight. We were on the plane for almost 11 hours and we just had a small lunch and a snack that was tiny. We were starving when we got off. Next time, British Airways gets my money. I want to know what airline I am paying for all the way through without the switching shenanigans."
Cons: "lack of info on flight delays. missed connection. no help. paid more for earlier flight then got put on late flight tht was $200 cheaper ...NO REFUND"
Pros: "By far the best trip I have made in a while"
Pros: "Arrived early"
Cons: "I was told that a transport would be available upon landing, it was only there for first class patrons. We landed 20 minutes late due to maintenance issues and I missed my flight by five minutes. I feel that united could have expedited my departure from the plane."
Cons: "Who has been charged for overweight luggage in the past year? Luggage scales at Denver airport are several pounds off from one to the next. They don't seem to get calibrated. This could easily be a class action lawsuit! Not to mention the supervisor, Dale Slosky was extremely rude and did not address the situation! United Airlines, please provide better training to your staff that you call supervisors."
Pros: "kind employees"
Pros: "The crew were helpful and did their best to manage delays."
Cons: "United is has delayed my flight on 3 out of the last four trips. 40 minutes, 1 hour, and 2.5 hours."
Pros: "How can they keep on squeezing people in a plane... this is becoming ridiculous"
Pros: "Entertainment was offered on the flight"
Cons: "Flight was 90 minutes late Crew took an additional 40 minutes to get passengers with disabilities off the plane. There's no reason it should have taken that long. After I paid for entertainment, the crew announced it would be free for everyone since we were so late. Crew member was super-grouchy. Seats couldn't be smaller if they tried to sit you on a postage stamp. I'm a tiny person, but this is ridiculous!"
Cons: "On at least one leg of my trip both two and from my destination the flight was late. As if that wasn't bad enough, twice the plane was over sold and people had to be removed to stay and catch a later flight which in turn made the plane even later. Many people either had to run to catch their connection or missed it all together. Several of which had small children. I fly about half a dozen times a year and this was the worst of the year."
Cons: "I was two hours delayed from my originating terminal in Denver due to a snow storm overnight. I arrive into Houston two hours late only to re adjust my remaining flights back to Denver. Two days later. What was supposed to be a one day trip to get my kids to spend it with me in Colorado. Is now turning into a three day filled adventure in airports."
Cons: "Read above comments that were meant for the Denver to Houston flight!!!"
Pros: "Inflight entertainment lacking so I slept all through"
Cons: "Inflight entertainment"
Pros: "Wonderful atmosphere despite turbulence"
Cons: "No dinner :) (not crucial, but is often nice to have)"

Pros: "The crew members during boarding were sensitive and very urgent in the process."
Cons: "The only delayed flights were the ones fron United, all the other airlines were on time. The attendant was stubborn and made comments not appreciated I lost my connecting flight in Houston and had to stay 8 hour in the airport until 6M Horrible experience"
Pros: "The plane itself was beautiful and seating very roomy."
Cons: "Mechanicall problem was nothing more than routine maintenance according to the pilot. After sitting on the plane 2 hrs with continued further delays I opted off and took a different flight which arrived 3 hrs later than originally booked. Very very annoying. At least I didn't miss my connection like many many passengers on board."
Pros: "Good flight attendants."
Cons: "After cancelled flight due to weather, process for booking hotel handled poorly. United's customer service says they partner with hotel booking agency to get you a discount, but this is either false or unlikely. The price you pay is the same."
Pros: "The seat next to me was empty"
Cons: "I landed at Houston at 2am and there was no food options open or comfortable sleeping locations fo Try to rest"
Pros: "Not much."
Cons: "The plane left late due to electrical issue – light was on and had to be checked, and then we arrived in Houston very late and the captain said we had to push back to 3 inches. That's ridiculous. We are already late and people up out of their seats and we had to go is down again."
Cons: "PRICE, overcrowding, crying kids, crew wasn't very polite they seemed irrittated"
Cons: "Took me four days to get to my final destination due to flight cancellations and delays with absolutely zero customer service. Had to jump through hoops to get on my final connecting flight."
Cons: "No entertainment"
Pros: "Flight was ok after a delay. No entertainment or food"
Pros: "Price. You get what you pay for"
Cons: "Why does the city have to fix a ramp? Leaving Denver was late arrived in Houston late. Cant get off plane due to equipment issues."
Pros: "The male agent at the counter was great! Unfortunately that was the only good thing about the trip. Everything was SO expensive, had to pay $1.99 for a bottle of water which is free in other flights. The crew on board didn’t do anything and didn’t come through to collect trash until the very end."
Cons: "More affordable prices, snacks and drinks available in flight, and a more helpful crew on board."
Pros: "Crew was nice"
Cons: "No WiFi, no food."
Pros: "Crew was personable and helpful"
Cons: "Longest boarding I’ve ever experienced."
Pros: "FLIGHT WAS QUICKER"
Cons: "FLIGHT GATE CHANGED FROM TICKET, COUNTER BOARDING WAS "UN-ACCOMODATING"."
Pros: "Delayed 2 hours. Arrived at Houston and another 40 mins to get to the gate. I lost my connecting flight to Guatemala 7:42pm"
Cons: "We boarded before the air conditioning was working. We boarded before the pilots were at the airport. There was no resin to board that early. Lack of information from flight crew once we were on the plane. Very few announcements or explanations. Then once pilot was onboard, flight crew"
Pros: "THE CREW FINE"
Pros: "Flight was delay 5 hrs..... with no one telling us anything."
Pros: "The crew was great"
Cons: "Nothing"
Pros: "Cheap flight, quick boarding."
Cons: "Cramped accommodation, extra fees for luggage, no complimentary beverage service. I’d call it the Grey Hound of the air, except I recently took a Grey Hound and I was much more comfortable."
Pros: "I paid 270$ extra for the carry on bags for the three tickets. If I knew that I would have chosen United tickets because they would be cheaper."
Cons: "Kayak you guys fooled me and I’ll not trust you again."
Pros: "Friendly staff"
Cons: "Disappointed that I had to pay for Carry-on luggage. Ridiculous! This is my first time flying without reclining seats. Ridiculous!"
Pros: "Lack of turbulence"
Cons: "It's a domestic flight on a budget airline. There is plenty to not like."
Pros: "That I'm finally home"
Cons: "The entire experience"
Cons: "I never took this flight. It was cancelled but u continued to keep sendimg me emails about check in .i never was chatged as far as i know . So very poor. My flight out of san antonio with frontier airlines was awful!!"
Pros: "Seats are confortable"
Cons: "Food and drinks are expensive"
Pros: "The ride home"
Cons: "The 4 hour delay that received once we arrived at 4:30 AM to catch our 6 o'clock flight home to find out it had been delayed until 9:28 AM. Once we were on the plane we were then told we would be delayed until 10 AM. Flying with two children was difficult for a four hour delay. However front tier did give us all $10 food vouchers and $50 vouchers each for our next flight. Once we landed in Houston we then sat on the tarmac for another hour waiting for the gate open. The plane did have mechanical issues which caused the delay but still the notice given was always last minute"
Pros: "On time. Priced low. Staff professional, friendly."
Pros: "The cleanliness and newness of the plane and the price of the flight! It's like I stepped into a bran new 2017 plane."
Pros: "Your flight crew on this flight was absolutely amazing and professional. I fly quite often and this was my first trip flying Frontier Airlines and I was not disappointed. I would like to say a special shout out to Stacy who was amazing at her job and very professional. It's refreshing and nice seeing somebody who actually wants to be there and enjoys their job. Please pass on my gratitude to Stacy as it awesome flight. Go as far to say give this woman a raise! Thank you very much I will definitely fly again."
Cons: "Getting off the plane seemed like it took forever but honestly no complaints other than that. Thank you."
Pros: "The water"
Cons: "Were over charged for baggage and then told it was our fault for bringing luggage on a trip. Charged me 120 dollars for a 55lb. Bag. We were specifically told 15 extra dollars not 75 dollars. Will never fly frontier ever again and after earning 82000 point in the last 2.5 years. I'm done with Frontier. My business will search out better less misleading airlines"
Cons: "Carry on charges"
Cons: "$40 for checked bag Paying for juice/coffee inadequate legroom"
Pros: "Flight not over booked Cheap ticket"
Cons: "$45 to bring a carry on ? Attendant at the gate was ill prepared for her tasks. Almost like it was her first day, and she had no one there to help her. She had no clue what to do with people gate checking strollers and instead of finding help, she stood there looking helpless."
Pros: "Like everybody else I didn't like the carry-on/ luggage payment. But you can still take one personal item(laptop bag/purse) for free. Also with cheap air-fare, I really don't have to complain about anything! All the details regarding boarding pass, online check-in, baggage, seats, etc is mentioned on their website, so if you don't choose to pay attention before boarding the plane then its not airline's fault. My flight was delayed 3 times. But I was informed well in time through automatic updates I signed up for. Frontier's Google App is very helpful to track the flight status, etc. Staff was very kind and courteous. Airplane was clean. Thank you for serving chilled water. I appreciate it."
Cons: "Apart from the flight delay, I didn't had any trouble in flying with Frontier."
Cons: "Flight delayed 2 1/2 hours whike a page from the log book was found. Apperently because of the large plane they couldn't bring in another one."
Pros: "Flight was fine. Short flight of 2 hours, but no snack or tv."
Cons: "I wish all planes had a tv on the back of their seats!"
Pros: "Overall, nothing stands out as exceptional. Just basic. Crew was ok but on both segments of my flight, I found them to be somewhat unprofessional as they were all having personal constrains with each other and seemed a bit annoyed if a passenger needed something."
Cons: "The seats were the most uncomfortable plane seats I've ever sat in. I would recommend frontier for more than a 2 hour flight."
Pros: "No TV, sears do not recline, Frontier sucks"
Cons: "Nothing"
Pros: "We were on time"
Cons: "$40 for luggage and I wasn't told it was credit card only so I had to go through half the airport to buy a pre paid card...another $5"
Pros: "Never got to go"
Cons: "Cancelled, very difficult to figure out how to get a refund (directed to frontier homepage... dead end.)"
Cons: "The flight was cancelled"
Pros: "The prices of course, the crew were friendly- but it wasn't anything outstanding.... just the casual hello and good bye. And baggage price wasn't bad."
Cons: "It's cramped, there wasn't much else that stood out"
Pros: "I had no problems"
Cons: "The airline charges for everything. People need to know you get charged for carry-on or checked bags, you get charged for drinks too. Just know what you are getting into...seats don't recline, no inflight entertainment...if you get an extra cheap flight, great, if not it's not worth it."
Pros: "Paid half as much booking w Frontier. First experience w them. Less comfortable (hard seats, leg room) but worth the trade off for 2.5 hr flight. I made a somewhat last minute decision to fly out on a one- night trip. Paid $45 each way to carry on my laptop. Rough landing coming home."
Cons: "Thin, hard seats; less leg room; $45 carry on charge each way for laptop; rough landing; one of attendants was rude."
Pros: "Getting off the plane, pilot and crew on plane."
Cons: "There was nothing to like. Ticketing was horrible. Cut off times not allowing people to get on plane in phoenix. It was chaos. The police were called on one man. Charge for carry on and refreshments card only with No warning at time of purchase. Had to throw away my luggage."
Pros: "My seat, but I paid $30 for it"
Cons: "Hook with a deceptive low cost, then charge for seats, carry-on as well as the charge for checked bags most other airlines impose. Snack offered for a fee only. Any drink other than water for a fee only. Really?? Then flight attendants push credit card. Offensive. Won't fly Frontier again."
Cons: "Never will fly Frontier again. Customer service very bad, a bunch of morons."
Pros: "Frontier seems to have more leg room than the typical economy seat. Also, they didn't lose our bags. That's about all the positive that I can say."
Cons: "The return flight was delayed by nearly 3 hours. Once on board, it was very warm for the entire flight. Also, Frontier is a good deal for a reason- there was no in-flight entertainment option, any drinks except water are provided at a cost and there is a charge for carry-on luggage that will not fit below the seat."
Pros: "The flight was uneventful."
Cons: "2 hour and 45 minute delay. Nothing offered in compensation, paying for every bag, and the seats are uncomfortable."
Pros: "Nothing"
Cons: "First time flying with Frontier and two of the flights were delayed over an hour..."
Cons: "Late"
Pros: "I arrived"
Cons: "Late - as usual!"
Pros: "I liked the crew, they were very personable and nice."
Cons: "Charging $40 per carry on? Are you kidding me?? We didn't budget for that and almost had to fly with no luggage. For this reason alone we are never taking another flight from Frontier. It's bad enough that Frontier charges for all baggage, but we had no idea when we bought the tickets off Kayak, that it would be an extra $130 for luggage. What a rip off. Then at the airport, the line to get a baggage ticket wasn't that long, but it took almost 45 minutes. Every time we fly Southwest or Delta, it takes only 10 minutes to get our baggage tagged and on our way to security. I was also unpleasantly surprised that even water costs $2. Other airlines give a free drink, but Frontier charges $2. Terrible. And the seats don't recline. In summary for areas to improve: don't charge me for carry on and don't charge me for water. I will also be looking for another online venue to buy my next tickets, we thought we were going to get a great deal (round trip tickets for two people for around $680) but instead will end up paying in the neighborhood of $885. Kayak let us down big time."
Pros: "Absolutely not one positive comment on this airline."
Cons: "I have never and probably will never have such a negative experience with an airline as I did with Frontier. The staff was rude and unruly. I was dealt with unprofessionally. Every process used was executed poorly. Then to top it all off I was contacted about the location of where my bad ended up.. Once I went to retrieve it, they no longer knew of the location. It took the employees an hour to find my bag and then I discovered it had been ripped open with missing items and they failed to mention that information when they called me with the location of it. Poor customer service and I would be embarassed to be a frontier employee."
Pros: "Nothing"
Cons: "We missed the flight so has to rebuy tickets from another airline with another $1600"
Pros: "Pissed to be charged 60 dollars for a carry on briefcase. Fuel costs are down its about time these airlines stop gouging us. I try not to fly Frontier and this reminded me why."
Pros: "To be fair, the last time I flew with Frontier was like 10 yrs ago. Back then, they used to be one of the best airlines out there. Sadly this time I was hugely disspointed by this airline. The seats are extremely uncomfortable, very little padding, do not recline and very small. Fell bad for the flight attendants because they were more of sales agents than actually attending the passengers. I don't think I will make Frontiet a flight of choice again."
Cons: "Seats are extremely uncomfortable."
Pros: "The assistance at the check in counter was great and I was able to move through the line quickly."
Cons: "The kiosks were broken at the Frontier at IAH that made the line a bit longer than it needed to be. Also, there was a last minute gate change that was annoying. I heard another passenger on another flight that said they had experienced a last inure gate change as well."
Cons: "Mechanical problems caused 3+ hour delay. Missed being able to pick up my rental and didn't make for quite the same evening."
Pros: "Clean and decent equipment."
Cons: "Loud credit card sales pitches at the end of a flight."
Cons: "You get what you pay for... they are not kidding when they say cheap with no frills.... nothing extra. Terrible seats, they don't even recline. No padding on the seat part."
Pros: "Stewardesses were very nice and pleasant. We left timely and arrived on time."
Cons: "My seat got randomly assigned and I was put on the back row window seat with no window. I wish I could have selected my seat from a list of free spots (w/o extra charge). I don’t like that you are charged for everything: seat change, water, and any snack. I would expect at least water as passengers get dehydrated from flying. Seats are uncomfortable, not much space from seat in front, and there is no recline. Feels crammed. Lacks hospitality majorly as I am charged for every little thing. I hope they don’t start charging for oxygen intake. I was not informed of entertainment options, but I’m sure they were not inexpensive. I will not be flying with Spirit Airlines again. There are other airline options that are less expensive (after you add all the additional fees up) and much more comfortable and hospitable."
Pros: "Cheap n effective"
Cons: "Airport work"
Pros: "Everthing is better"
Pros: "Price"
Cons: "Unable to get refund for a flight that hadn’t been missed yet"
Pros: "Crew was easy to work with, friendly & accommodating"
Cons: "Nothing! Good crew!"
Pros: "Good cheap fare"
Cons: "Smaller carry on size"
Pros: "Boarding was on time, take off was smooth, it went better than I thought it would. Not a lot waiting, no long lines."
Cons: "Paying for the snacks and having to pay extra for bags."
Pros: "The flight was good"
Cons: "The very long delay."
Pros: "Good flight on time great crew."
Cons: "Attendants were rude"
Pros: "Was pleased to have extra leg room."
Pros: "Left on time, landed on time, good flight, cabin crew helpful"
Cons: "Gate agents not very friendly, extra fees for all bags were not clear until we were already at the airport"
Cons: "The seats were very cramped. Everybody was pretty much sitting on top of each other. The comfort level was very poor. Having a bunch of screaming babies and children made the flight worse."
Cons: "Quality and ease of use of the web site... very difficult to navigate..also, it looks like it was designed for a 5 yr old Price of luggage is way out of line... Charging $3.00 for water is totally unacceptable..."
Pros: "Comfortable seats with plenty of leg room"
Cons: "I wasn't able to choose my own seat and got stuck at the back of the plane in a "window" seat without a window. Being unable to see outside with a very rough flight made me so nauseous. I was highly disappointed in having to pay to carry on my small suitcase. Or pay for a can of pop. Seriously? And there was a gentleman in front of me that caused us to be delayed about 15 minutes on anew already late flight. I probably won't fly on Spirit again."
Cons: "Flight was cancelled with no reason given, it took almost an hour to call and get my return trip cancelled because the website would not allow me to change my flight. Representative tried to reschedule me for a 12 hour trip when the original flight was 2.5 hours before finally cancelling my trip all together. Spirit ended up costing me $150 more than had I booked with another airline at the beginning because I was left having to purchase a ticket day of on a competitor."
Pros: "The air host was kind and funny"
Pros: "Flight attendants were great!"
Cons: "Paid almost double the price of my ticket during check in for bags and to also purchase an actual seat. You'd think a seat is included in the price. Tried calling customer service with an issue on my boarding pass, and there is no customer service representative either. All automated and unable to get through to anyone for help."
Cons: "Our luggage was supposed to come out of carousel number 3. It took an hour for the checked bags to land after we had arrived. "Karen" at the luggage window next door, was incredibly rude and unhelpful."
Cons: "Late."
Pros: "Clean airplane"
Cons: "At baggege now for 52 minutes AND STIL NO BAGSS SHOWING UP!!!!!!!!!!!!!!!!!!!"
Pros: "Low airfare prices. You can't beat spirit."
Cons: "No TV are WiFi. Spirit should give complementary drinks like all other airlines."
Pros: "Price Easy"
Cons: "Nothing. Was cheap and what I needed."
Cons: "Everything was over priced especially checking in luggage"
Pros: "Nothing"
Cons: "I was charged $100 at the gate when I was told my carry on was free when checking in! Bogus airline. You lay $110 for a flight then are bombarded with $160 worth of bag fees. So unfair!"
Cons: "My luggage was lost. The agent that helped me didn't even appoligize on behalf of Spirit. She was very rude, and acted like she didn't want to be there, which made me even more mad and upset that my bags were lost. I don't know if I would fly Spirit again. It isn't worth the savings after you are nickeled and dimed. Also, customer service needs some improvement."
Pros: "Cheap"
Cons: "Spirit lost our luggage"
Cons: "Flight was delayed 1.5 hours airline attendants did not know where bags were to come out said ask gate attendants took forever for bags to come out. There is alway problems with spirit airlines flow them 4 time problem every time"
Cons: "We didn't take off on time. this is so common with spirit airlines"
Pros: "Staff was super friendly and helpful!"
Pros: "Fast boarding, but then we sat with the door open for 20 minutes. Flight was fine. I would only ever consider flying again if there was a phenomenal price break from the next cheapest airline."
Cons: "Gate change with no announcement or change on departures board. Late takeoff. Tiny cramped seats, and miniature tray tables. Trash in front of my seat at boarding. The majority of passengers seemed to be inexperienced flyers, maybe gravitating towards the cheap fare? VERY annoying, needy, chatty, panickey at take off and landing. Not a pleasant environment."
Pros: "Bought my ticket day before and paid $100 for base price plus about $50 in fees for cheap seat and luggage. Quick boarding process. On time/early flight."
Cons: "They charge for everything, including water. Tray table isn't really a table - it's a ledge. Seats don't lean back and are very uncomfortable."
Pros: "The flight landed early which is great. The staff was friendly, and a flight attendant did the safety brief to the tune of "Leavinf on a Jet Plane" by Peter Paul and Mary."
Cons: "Spirit Airlines really should have an app!!! Everything would go much smoother if they had an app, and I think I'd probably be more loyal to Spirit if they make the ticket buying/ saving them in passbook smoother and easier."
Pros: "Crew was pleasant and flight was on time."
Pros: "Courteous crew."
Pros: "flight price before bags"
Cons: "Seating the worst I have ever seen, husband 6'5" will never fly spirit, bags cost to much. I returned on Southwest and it was well worth the $50 more. I paid the same price on spirit when the bad fee was so expensive. I can get two free bags, leg room, drink and snack. Not worth it."
Pros: "Price!"
Cons: "Seats are rigid. Given the price, it makes sense. I didn't expect anything else."
Pros: "Cheap last minute prices!"
Cons: "No customer service is probably due to cheap prices!"
Cons: "everything"
Pros: "Same crew and plane as the first flight from Detroit to Denver, friendly and helpful. Comfortable with what room I had."
Cons: "This was my first time flying Spirit and I was unaware of all the extra fees, I ended up paying the same if not a little more than I would have with another airline. I ragweed food and entertainment a 3 because there was no N/A option, I brought my own onto the flight and did not purchase any from the airline."
Cons: "The flight was delayed and I missed my connecting flight, had to wait 17 hrs before being able to fly."
Pros: "We were given good seats together. The flights were both on time."
Cons: "Not very much leg room."
Cons: "Seats are horrible with no leg room! I'm 5'10" and I was so uncomfortable and I had to pay $10 for it above the ticket price!"
Pros: "Friendly staff."
Cons: "The bagage fee is more than other airlines. The website asks you to pick a seat and then charges you for each seat and each flight so it could have been $ 120 more for my family. Early check in fees are not appreciated."
Pros: "The staff was very friendly !"
Cons: "Offering water for free would be nice."
Pros: "The initial ticket price (if that included the seat), baggage I understand"
Cons: "Hidden charges: Why did I have to buy my seats? Is it not included with the ticket? I had to pay an additional $158.00 on top of my $176.36. Online is very misleading."
Pros: "The low prices when timing is correct. Great departure & arrival times"
Cons: "The new seats, tray tables, seat pockets give the overall appearsance of "cheap". Customers will have to get used to another round of "no frills". Hate using credit card for a drink of water."
