Airline reviews

Pros: "Did not know I had to bring or buy own dinner and breakfast. I didn’t see that written anywhere."

Pros: "She was cute, really acted like she liked her job! Left early and arrived early."
Cons: "I wanted a candy bar instead of the mai tai"

Pros: "Crew was efficient, pleasant, and had a sense of humor."

Pros: "The crew and gate people were friendly and helpful"
Cons: "It would have been nice to have a choice of free snacks, other than the biscoti"

Pros: "I'm glad it was a short flight!"
Cons: "It was hot. Really, really hot. They were talking about taking us back to our destination, but that call, positive or negative, should have been made before the flight as we didn't have equipment failure post-boarding. The idea that we'd go back is ludicrous if we'd already pushed from the gate. Get it together, Alaska."

Pros: "Everything! Leg room, friendly crew, good food. Easy check in."
Cons: "Not applicable"

Pros: "tablets were perfect for my seven year old."

Pros: "Extremely friendly crew and they were very apologetic for the delay. Very comfortable flight"
Cons: "There was a one hour delay and I really wish I had gotten an email telling me about it before I left"

Cons: "The flight was delayed."

Pros: "Very friendly crew. Efficient boarding."
Cons: "Small selection of movies. Must use one's own portable device to view movies, or rent one of their tablets."

Pros: "Staff was great."
Cons: "Food options just ok. Seats super small"

Pros: "My first time treating myself to first-class, so it was very nice."
Cons: "Delayed an hour at departure, and then got bumped out of first class on my connection, which they did change to a later flight; however, sadly no one looked very concerned about the fact that I'd like to have continued my flight in the class I PAID for. More on that in my next flight review."

Pros: "Alaska provided a food voucher and a future flight credit."

Pros: "It was on time and 30 minutes early to our destination!"
Cons: "Nothing"

Pros: "Comfort,service , and plane all great !"

Pros: "Left early, arrived early"
Cons: "Tell me about the entertainment software before we get to the airport."

Pros: "The boarding process was unhurried and they offered free checked bags to keep the overhead storage from overflowing."
Cons: "The noise level in the cabin was high. I'm glad that I have Bose noise-cancelling headphones."

Pros: "Great service"

Pros: "Flight personnel were focused and expedient. We arrived on time."
Cons: "First time flying Alaska outside of the Mainland. For a five hour flight, surprised there were no complementary meal service. Only beverage cart services. Flying five hours to Maui, Hawaii is a bit different than a 1 hour flight to Portland or Seattle. Price of Alaska economy ticket no less than their next competitor (i.e., Hawaiian Air, etc.) on the same flight route offering meal service. May want to rethink pricing model?"

Pros: "Flight was cancelled!"

Pros: "The crew on Alaska is always great. They always engage in conversation and seem to be in good moods, and not cranky. I like the little prop planes. Plus the complimentary beer and wine is fantastic. What happened to giving the consumer a little something on any other airline? I mean I feel like I have to fight for a cookie."
Cons: "We were rushed on both flights I took this week with Alaska. It was to make up for lost time. It just was a jumble at the gate. It made up for the time but it feels like cattle being herded. And I hate that. But I was happy with being on time so, good and bad I guess."

Pros: "leg room on premier seats. Entertainment had big variety and high quality."
Cons: "No food on 5 hour flight unless you pay"

Pros: "Cabin crew were very nice."

Pros: "The fact that there is air service is great for someone who has disabilities. It is a shame you have to rely on assistance of train or coach staff that may be or not be there!"
Cons: "Due to so few fly it is expensive"

Cons: "Two days before flight online seating chart showed no seats available that were together in main cabin so I bought "economy plus" seats. There were actually 32 empty seats in economy, many people had while rows to themselves. What a ripoff."

Pros: "the upside was that legroom was ok--i'm 6'2". plane did leave on time."
Cons: "1) not that alaska does any worse than others, but boarding is increasingly unpleasant. 5 grades of 'rewards' groups boards, then children, then military, then the elderly, etc. by the time people who paid full fair for their tickets board there's no overhead space left. by charging for any checked bags, the airlines are creating a very stressful and disorganized boarding experience; 2) the ambiance is just dull: cheesy music, dull, grey colors, poor lighting, etc. it just feels as if you're in a space designed by someone with no taste--and this is from the company that bought and killed virgin!? 3) the food is the same cheese plate and tapas plate i get on other airlines. 4) no special greeting upon boarding. it wouldn't take much to make the entire experience pleasant, but alaska and others don't feel the need to make the effort."

Pros: "The flight attendants made our flight very nice. They went out of their way to take care of us."
Cons: "Nothing"

Pros: "Alaska Airlines has chargers at each seat! So convenient. They also have free messaging, and movies! They also de-board their luggage super quickly - I walked off the plane, grabbed my luggage, and was on my way as quickly as if I only carried-on!"

Pros: "Flight crew was friendly."
Cons: "Nothing the crew could do; weather conditions"

Pros: "The flight attendants were kind."
Cons: "There were several issues with my electronic boarding pass. Both on my way in for this flight and previously on another Alaska Airlines flight."

Pros: "Plane was late. Ground crew did a good job keeping passengers notified"
Cons: "Plane was late, but can't help the weather"

Cons: "A long line for the aft toilets, and crew told us we couldn't use the empty toilet at the front because first class passengers pay more. This was TWO attendants making people wait when at least one other toilet was open up front on a five hour flight. Is this even legal? Very disappointed in lack of consideration for health and comfort. Thanks for listening."

Pros: "Crew were super nice, free beer and excellent landing! Great way to start my trip! Well done Alaska!"

Pros: "Fast and easy boarding even with a really busy holiday weekend. Clear communication with crew and staff who make sure to make things as easy as possible really made a potentially chaotic boarding really great! The type of plane is noisy, but I was still able to hear the flight attendants and they were patient with the passengers."
Cons: "I can't eat dairy so having a cheesy cracker snack is a bummer, but I my seat mates on both flights were really excited about them (I said they could take my crackers and they said their kids would be really happy) so I figure it's fine!"

Cons: "Flight was delayed seat was moved to middle seat after choosing a window seat"

Pros: "I like the announcement for every situation and weather and time. But people at the entrance do not say welcome and when you leave they don't say anything. Other wise it is very good."

Pros: "I am a flexible, thin, 5'0" person and had a hard time sitting on that plane! Ugh. I don't know how bigger people make it through the flight."

Pros: "Still waiting for our return flight to land"

Pros: "Crew very helpful since my mom required wheelchair and assistance. Very responsive crew members"

Pros: "Love the charging station on every seatback, friendly crew and healthy snacks."

Cons: "I couldn't understand the captain's message over the speaker....he either had an accent or the reception was terrible."

Pros: "I like the seats - the headrests wrapped around. That was good."
Cons: "They KNEW there wouldnt b enough room for the overhead luggage, so they offered to check bags for free. This is wrong: people bring overhead luggage because it won't check or cant check. It seems wrong to offer to check it because they already know its not all going to fit. also, the Alaska boarding procedure is really messed up, compared to Southwest which always runs smoothly."

Pros: "The staff was so nice and friendly. The ride was fantastic. Boarded the plane it was so comfortable and cozy landed safely without incident."

Pros: "Very pleasant trip. Everything went very smooth. Will fly again with you."

Cons: "The seats were suprisingly small."

Pros: "they were very friendly and funny :)"

Pros: "Very on time flight. Not strict with baggage."

Pros: "The crew was very good & accommodating. The seating was terrible and even though we were required to purchase it they ran out. It was the first time I have ever been UNHAPPY on an Alaska flight and I have been on many."

Pros: "They were totally on time. They were very friendly they were very professional and helpful. I like the fact that you can watch movies from their Wi-Fi for free on your phone. I also like the fact that there's an outlet at every seat so you can charge your phone and laptop. Much cleaner and more comfortable than most other airlines. Really my first time flying them I was impressed."
Cons: "I wish they had offered headset so that I can actually listen to the movies if they offer for free on your phone."

Pros: "the scheduled time offers, the fast boarding time"
Cons: "offer lactose intolerance snacks"

Cons: "Nothing"

Pros: "Everything went very smoothly."
Cons: "I wasn't able to connect my ipad to the free wifi for any of my four flights."

Pros: "Very good"

Pros: "Amazing crew"
Cons: "I had booked a window seat, the when I went to board, it was changed to an isle seat. I find that I dislike the sole due to the rudeness of people in general and I kept getting hit with purses and such from passing passengers."

Pros: "the plane didn't crash."
Cons: "honesty. 29 minute flight took 3 hours. first they blamed it on waiting for luggage, then they likely realized there were no connecting fllights, so that excuse didn't work, then they were 'closing the cargo doors' for 45 minutes, then they had to de-ice as the plane had now sat for 4 hours instead of 45 minutes, had it left on time."

Pros: "Short flight and no problems."

Pros: "Crew attentive and helpful"
Cons: "N/a"

Pros: "I was surprised that we received two meals and constant drinks in economy. Delta definitely has better hospitality than American."
Cons: "The seats were really tight between the rows. The space between the seats on the same row were typical."

Pros: "Comfortable Seating!"
Cons: "Flight delayed Quite a bit."

Pros: "Choice of Entertainment was excellent"
Cons: "Bigger snacks - 2 small cookies or small pack of almonds was indigenous 2 hr flight"

Cons: "Smooth on time flight"

Cons: "Everything was excellent."

Cons: "Seats are so small. Flight was delayed."

Pros: "Crew - Usual pleasant Dutch hospitality. Aircraft: Clean and nice Seats: Reasonable leg room , big Monitor easy operation. Meal: Outstanding personalized special meal requested. Served in each leg of my journey."

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: "Professional appearance of flight staff accommodating and sincete"

Pros: "Clean plane, the seat felt roomy. Smooth ride and the captain communicated clearly."
Cons: "It felt super hot and I wish there was food included in such a long flight."

Pros: "Glass of water and a quick flight was all I needed. Went very well."
Cons: "Small delay waiting for the walkway arm at the gate otherwise we’d have been early"

Pros: "Being able to watch videos."
Cons: "Flew with 5 family members. None of us were seated together. And we have 3 young teen girls. Flight overbooked."

Pros: "The flight attendants gave great service"

Pros: "It was too cold on the flight. I asked for a blanket and luckily the stewardess had one. However, before giving it to me, she told me it was the only one on the flight!"

Pros: "The Delta desk attendant at CVG was unable to come up with another flight to get me from CVG to Colorado Springs on 6/13. There is nothing to like."
Cons: "See comments above."

Pros: "Nothing"
Cons: "Wouldn’t let us take our carry-on because they had overbooked and had no more room in overhead. Delayed our first flight and then our connecting flight left *early*. (If you know you have customers with short connections, why leave early to make their connections even shorter?) Then told us they would not pay for our hotel since it wasn’t their fault. Gave us a “discount” with a nearby hotel that was more expensive than what you could book it for online. Had to wait several hours for them to get us back the carry-on luggage that they insisted we check in the first place."

Pros: "The exit row seat on this leg out of PHL to SLC did recline! No need for Delta Comfort+ unless you want to get off of the plane ... faster."
Cons: "For some reason, the pilot couldn't figure out how to adjust the cabin temperature for the first hour or so. This made the flight (and I was sitting in an exit row seat, right by the door which is usually cooler) uncomfortably hot and muggy. Food? No food. Thank goodness for Delta Lounge (even if it was the one in PHL). Just snacks make this a poor option for many. I don't know what is up, but the USB charger on the two monitors didn't work and neither did the outlet between the seats. And I have two different sets of cables "just in case" and they're the 3-in-1 so I can try to charge multiple devices (Apple, Android and Samsung) but nothing worked."

Cons: "Delta staff is not too friendly"

Pros: "Loved the roomy seats and the upgrade wasn't terribly expensive"
Cons: "Nothing"

Cons: "Seeing as I’m still waiting for my flight, more than five hours later I am not inclined to rank it highly. This airport is an embarrassment and I will try my best to never fly Delta again. Weather is no excuse for this."

Pros: "Nicest crew"

Pros: "Customer service was great"

Cons: "They change schedule day before we flight, the change schedule 2 time while were flighting"

Pros: "Could be among the best landings ever. I felt nothing as we touched down in Salt Lake!!!"

Pros: "Great service all around"

Pros: "Loved the Clear/Skymiles fingerprint boarding! Great line markers at DCA as well. Would love to see those in other cities."

Pros: "I loved his pilot. His take of and landing were so smooth. I wish I could request him and his co-pilot for every trip I take. The flight attendants served and did not hang around and harass you like some do. They were efficient."

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

Pros: "The entertainment was good and we didn't get charged for the blankets, as in other airlines, though it would have been nice not have needed them, the plane felt colder than 70 degrees!"
Cons: "Longer delay occurred when another passenger got into an argument with staff. It took soooo long for security to come to fix the situation so we could continue boarding. We were also packed in like sardines. I would pay more for more room, though business and first class are available, they're way too much."

Cons: "Very dated plane. First class seat was worn, crooked, and uncomfortable. No entertainment offered. Almonds or biscuit cookies were the only food options."

Pros: "The flight left on time and landed earlier than anticipated"
Cons: "The seats were narrow and very upright"

Pros: "Flight was very comfortable and had a lot of space to move around"
Cons: "The gentleman indicating on the loud speakers what zones will be loading first was very rude."

Pros: "Leg room was great compared to discount airlines. The built in entertainment for individualized interests was welcome. Crew was great."

Pros: "At least there was a free shuttle to the discounted rate hotel."
Cons: "There was not enough time to run to the connecting flight. Was told they could not wait, yet then the plane sat on the runway for 25+ min. Had to get a hotel and rebook the flight. Very poor experience flying Delta."

Cons: "Took 8 hours to get from Oakland to Los Angeles. Flight delayed then cancelled at Oakland. Driven from there to San Francisco. That flight delayed by 45 minutes. Got on board and then they neede 4 people to get off the plane since it was overweight. That took another hour. Bad day of travel."

Pros: "I didn't like anything about this flight. Only benefit of the doubt is the 2 hour delay as a runway in SF had shut down."
Cons: "We had seats at first where there was what looked like bubble gum bits stuck on one of the food trays. The flight was clearly not cleaned although it landed 2+ hours before the departure. We had to ask for a wet tissue and clean it up. That was of no use too as it wouldn't scrub off. My wife was feeling under the weather and so we asked for a blanket. The blanket was hardly a blanket and more like a towel. We then luckily could switch seats as there were 2 vacant. But, the air conditioner was leaking water in the seat to our left. The crew was callous and just stuck the passenger with some napkins saying it does that. I don't fly Delta a lot and my experience in this trip isn't inspiring much confidence."

Cons: "I was on the way to the airport when I was notified of the 1st delay. I am sure Delta knew there were issues already and should have let me know earlier in the day. The delays kept increasing. We were offered snacks at the gate. That is it. No free drinks on the plane, no free premium movies. Very bad customer service. More explanations were needed as to the cause of the delay."

Pros: "Gate agent arranged flight via Salt Lake City and also gave me $15 lunch coupon for my troubles. She was awesome!"
Cons: "Dealing with West Jet to refund a mistake on the ticket purchase."

Pros: "Enough said"

Pros: "Ability to change planes with a 30 minute layover."

Pros: "Great crew and service. Very smooth flight. Comfortable seats."
Cons: "Older aircraft without seat back video."

Pros: "I was upgraded to First at the gate. The crew was very professional and friendly. Food mini-minimal, but OK."
Cons: "On this A320 craft, old style, the First class seats are a joke. I had seat 2B. The pitch is apparently less than in the Comfort+ rows. The passengers in 1A and 1B started reclining even before departure, and during the whole flight. For me and my neighbor, with that seat on our chest, it was impossible to reach down to the seat-back pocket, not to mention to the bag stowed under the seat in front. To get out of the seat, I almost could not get my legs through the 5-in. interval between the back of the front seat and the irremovable armrest. I shook the passenger sleeping in 1B rather violently a couple times. The lady in seat 2B apologized, but she had to climb and put her feet on my seat to get out of hers, there was really no other way. Delta needs to address this ridiculous situation of their First Class seats urgently."

Pros: "Flight was on time."
Cons: "Seats are not comfortable, tray tables are tiny, amenities are non existent without a surcharge."

Pros: "the only thing I liked was the cost."
Cons: "$40 for carry on bags..$30 to check in...Seriously???? This must be the way to make up for the cheep tickets...And what is the extra charge for a seat???? Never heard of this on any other airline. I have one more Frontier flight in afew weeks and this will be the last. I am going back to Alaska or Hawaiian..cost is more, but much better service. Cost for one coffee and snack $4.49...snacks $2.99 soft drinks $1.99 Is Frontier filling bankruptcy???? problems with management????"

Pros: "The planes did seem a bit newer than some of the planes with other airlines."
Cons: "The fact that Frontier charges for both checked luggage and carry-on luggage is enough to make me not want to use this airline again in the future. The food and drink options on the plane are also ridiculously overpriced. If Frontier were to price their in-flight food and drinks they would make a lot more money as budget minded people like myself would actually buy an item or two as opposed to refusing to buy anything at all. Overpricing food and drink items and charging for checked and carry-on luggage also has the added negative effect of me never wanting to use this airline again in the future. I will also actively dissuade friends and family from using Frontier."

Cons: "VERY uncomfortable seats!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"

Pros: "The flight was a little rough, but we boarded and landed early. Not bad overall."
Cons: "No onboard entertainment and very limited food."

Cons: "My luggage was misplaced on the plane and I waited for an hour for it and it went to the wrong section. I paid two dollars for a soda. St. Louis frontier desk is not open from 930-3pm which is crazy ridiculous. Also your plans are extremely uncomfortable and have become just like military planes. $30 for a carry on is excessive and $25 for a checked back? Absolutely not. I will not fly frontier again."

Pros: "Nothing"
Cons: "We buy with my friend seats together online and when we went to the airport they changed our seats"

Pros: "???"
Cons: "The seats are like benches. I had to have a body massage as I arrived due to body ache There was no food Paid $40 bucks for my carry on"

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: "Only the price it was cheaper than other airlines"
Cons: "1. The security now a days has long lines and I get to the airport early but can't drop my luggage ,no one was at counter until before 2 hr for departure 2. Unlike other airlines no free snack during the flight 3. Charged for every single thing , seat , food , snack , carry on ...."

Cons: "The flight was delayed and the airline charges for everything. They tried to charge me for my CARRYON bag which is hilarious, and I proceeded to say I would not pay that charge. The attendant let me board the plane anyway and I put my carryon in the overhead without an issue, which deeply concerns me. It seems as if Frontier arbitrarily tacks on that charge, tricking their customers like con artists who will fall for this absurdity. The air conditioning did not work well and they almost forgot to give us water. Maybe they even charged for the water. The attendants were rude. Dont fly Frontier unless you really really really need to save a dime or two."

Pros: "Boarding went smoothly."
Cons: "One of the flight attendants was rude when I was taking my seat. She was rushing me to sit down and put on my seat belt, when I had my own row and no one else was affected by this. Then, as we were landing, the turbulence was bad and we were descending extremely quickly. The plane then pulled up and started ascending back into the air and did a lap around the airport. I wasn't sure we were going to make it back to the ground in one piece. Not the most comfortable experience. Overall poor flight."

Pros: "I liked the convenience of hours flown during my travel time."
Cons: "I did not like the outdated seats which had no headphone adapter, no charger for phones,."

Pros: "All conduct was very good."
Cons: "No food, no tv, no magazines"

Pros: "Cheap ticket"
Cons: "I booked a round trip ticket with Frontier and on both flights the crew was rude. They need to send the flight attendants of this airline to a hospitality course or something. All other airlines I've traveled on I've never had a problem with the crew. I will stick with Delta and United from now on even if it costs more."

Pros: "The fact that they itemized the cost for everything is OK and will make you to take a conscious choice of whether to bring a carry on luggage, buy water or food. You have be very self disciplined to NOT have costs added to you. But atleast I like that we have a choice but a very HARD one to make."
Cons: "Itemized costs for everything - can be a pain and add up to the costs. I mean charge for beverages, water and light snacks, thats pretty standard and expected. So it leads to very bad customer experience and feeling annoyed that you have to pay for everything. Although I dind't pay for carryon, or any drinks or food as I didn't get any. I felt annoyed and went a way with the feeling. I am NEVER going to fly frontier. Although I might fly frontier in the future that might be my last resort and will try to Avoid it as much as I can."

Pros: "This was my first airplane flight ever. I was extremely anxious. However I don't think it could have gone better. I had a cat with me and everyone was welcoming."
Cons: "The only things I'm upset about it there were no healthy options on the menu. Even sodas like Izzie or some Bolthouse Farm/Naked juices would be nice to have for those who avoid anything processed. Fresh fruit would be good too. i was also shocked that I had to pay $80 extra for my ONE bag to fly to and fro, and that my cat had to count as my personal item so I had no choice but to pay for one. I believe we should have a free personal item and 1 free carry on."

Pros: "Nothing. This is the first and last time I will fly frontier."

Pros: "Seats were dirty smelly floor was gross panels loose"
Cons: "Nothing was up to the mark"

Pros: "The boarding process was pretty fast."
Cons: "Talk about hidden fees! You have to pay to choose a seat and pay for a carry on. You're allowed a "personal item" that has to fit under the seat in front of you, but what they don't tell you is that the seats are "sardines in a can" seats only about half as deep as traditional seats (so that personal item has to be smaller than you'd think). So let's talk about these seats. They are literally an inch thick. Like I mentioned previously, the seat part is only about half as deep as normal seats. It ended at mid-thigh for me and I'm short (5'3"). Accordingly the tray tables are only a hand's width, put a drink on it and that's about it."

Cons: "Hated to pay for a seat, no snack, not even water served, tray table a joke, too crowded, no movie no TV , no music, flight boaded early, arrived early and then sat on the tarmac, no gate available. Bags too expensive! I will do my best not to fly Frontier again."

Pros: "Boarding was good."
Cons: "Seats were very uncomfortable. Frontier jabbed with additional fees at every opportunity, including charging us for our carry-on luggage, which I had never seen on any other carrier. Also charged for any beverage or snack -- unheard of!"

Cons: "Charged for carry ons!!!!! Gas prices are down pass it onto your customers. stop charging us for every little thing!"

Pros: "Front ones were nice."
Cons: "These 2 ladies need another job. Customer Service is NOT in their vocab"

Pros: "Seats very small and uncomfortable. Can't recline"

Pros: "Left on time, arrived on time"
Cons: "The gate attendant is hard to understand when making announcements before boarding"

Pros: "Price of the ticket."
Cons: ".this was definitely a "no frills" flight."

Cons: "Everything was fine except the seating. It was the hardest most uncomfortable seating with no flexibility. I am a small person and for a 2 1/2 HR flight my wife and I both very uncomfortablez"

Cons: "There is a fee for carry on bag too."

Pros: "Nothing, service when we got to the airport was terrible we have been charged for 40 dollars extra for our lugagges for nothing."
Cons: "Everything,, service when we got to the airport was terrible we have been charged for 40 dollars extra for our lugagges for nothing."

Pros: "Like any flight, boarding a unloading was efficient. That's about the only good thing."
Cons: "The seats were small, uncomfortable, with no head rests. I had a back ache the entire time and left the plane miserable. Seriously, spend $50 more and fly with a modicum of comfort instead of like human cattle"

Pros: "Chairs don't recline. Bags sent to wrong claim area. No leg room. Plane was freezing."

Pros: "The flight attendants gossiping about the other crew!"
Cons: "Having to pay for seats, mobile check in that kept thing me I hadn't paid for the seat, having to pay for a bag at one price at check in and a different price at the airport (it goes to the same place people), having to pay for your carry on, really?!!!?, having to pay for a pitifull snack, pay for a soda (surprised you don't have to pay to use the toilets!) And could you get any meaner flight attendants. The poor guy next to me seat didn't work and she practically bounced him off the plane cause he couldn't get his seat back in an upright position. what we thought was a great ticket price ended up being more than Delta!"

Pros: "Not one thing! Flight attendants were rude, the seats were the most uncomfortable seats I've ever sat in."
Cons: "The whole experience from check in to getting off plane. I will never fly frontier airlines again. I never complain I usually just don't use or buy again ,but the was a terrible experience . Wasn't expecting luxury but wasn't expecting misery."

Pros: "The crew was fabulous as was the boarding process."
Cons: "The seats are terribly uncomfortable and no longer recline. There isn't any entertainment or food provided so hopefully you have something to occupy your time. My checked baggage surpassed the 50 pound limit and I was charged an additional $75 on top of the $30 checked bag fee."

Pros: "The crew was wonderful and the flight comfortable Thankyou Mary Pete"

Pros: "I liked having a direct flight to my destination"
Cons: "I would have enjoyed having digital plugs in our seats to access wifi during the flight. Originally booked our flight for the low fair but realized upon check-in that checked bags were $35 extra each. The extra cost of the 2 checked bags made this flight comparable to Delta. Will probably fly Delta next time so we have the "creature comforts" of Wifi and in-flight screens in each seat."

Pros: "on time, friendly"

Pros: "The flights were great. Left on time and arrived early!"
Cons: "Nothing"

Pros: "When I boarded and saw the thin, molded seats I braced myself for a long, uncomfortable flight, however to my surprise the seat was the most comfortable Economy seat I have sat in over the last few years. Nothing on United, Americannir Delta compares. Nicely done! In other reviews people have complained about the cost of stowing carry on luggage. I found the disclosures about the fees very clear and easy to understand, which enabled me to select the best option for me. Even when the beverage cart came by and I requested a Coke Zero (which they had!) the flight attendant, verily politely reminded me that they do charge. As I told her, at 30,000 ft, $1.95 seems very reasonable for a can of soda. There were no surprises, and the staff was great. I will definitely fly again."

Cons: "The seats didn't recline"

Pros: "Carew was professional and friendly. Flight was on time with no issues."

Pros: "Nothing"
Cons: "Fees for seat choice, no entertainment, most uncomfortable seats, no leg room (I'm 5'6 140#), fee for a can of juice, terrible and expensive (snack) choices, mechanical difficulties for this airline are the norm."

Pros: "The pilot did a great job of landing in very windy conditions."
Cons: "I've been flying for many years, and I miss the hospitality of the free snack and drink."

Pros: "One hour delay in takeoff !!??"
Cons: "Surprise charge at desk for a CARRY ON bag that fit above the seats. So you made me to be a sucker. Trick them into the seat and then charge."

Cons: "Ridiculous passengers nearly causing a delay in our flight."

Cons: "Charged me for my carryon, no water (you have to buy) no snacks (ie. peanuts, you have to buy) squished seating (no reclining seats) families couldn't book seats together (you have to pay), so kids were distributed all over the plan without their parents. If this "pay if you want" model works for you, by all means, but it doesn't make for great travel experience. I will choose other airlines."

Pros: "Good flight"
Cons: "Just remember, you get what you pay for. My flight was $148 from Denver to Chicago on Frontier."

Pros: "The crew was very friendly"
Cons: "I'm not a tall person but still found the seats very cramped. I wasn't aware up front that Frontier is a budget airline (i.e. you have to pay for a soda in flight and pay for a carry on...) so that was a surprise. We also had to wait 45 after deplaning for the bags to arrive on the baggage claim, and it was when it finally came, it was to a different claim (the staff never updated passengers or signage)."

Pros: "They refunded some of my money back"
Cons: "The crew didn't show up for our 6 a.m. flight. Most airlines would have a contingency plan for this which might include (a) early notification to passengers (b) automatic rebooking connections. Pretty much all would be able to get you to your continental U.S. destination sometime that day. Frontier can't and doesn't even try. They informed the passengers of a 4.5 hour delay right at the time we were supposed to board. Then they informed the vast majority of the passengers with connections that not only would we not make the connections but that we would not make our final destinations that day (it's still 6:30 a.m. at this point). They refused to book us on other airlines. They offered to either give us $100 for a hotel or to refund this leg of the trip and our $40 carry-on fee (another scourge) and told us good luck. I booked a very expensive one-way flight on United so I could get home."

Pros: "Good accommodating staff"
Cons: "Heavy charges for luggage Improvements in website"

Cons: "Delayed for no reason"

Cons: "Seats were very uncomfortable. Extra charges to even sit next to those who were booked in the same booking. Aircraft was dirty."

Cons: "The flight attendants were extremely rude, you dont even get water or a free check on bag... so good luck"

Cons: "Still look for the first on time flight, no luck so far"

Pros: "Seats. Cheap."
Cons: "Outrageous fees if carry-on too big."

Pros: "Nothing"
Cons: "Charging for the carry on luggage Rude service at the counter Even they messed up with boarding pass (both boarding pass on same name) and after that they showed the attitude instead of fixing their mistake !"

Pros: "Had heard bad things about Spirit before, but liked the departure times so brought the ticket. Delayed flights, terrible seats on the plane, ridiculous extra charges for baggage, overall bad although not awful experience, but not worth the cheap tickets."

Pros: "You sit on a metal bar with a plastic concaving back. And there is some thin semi-cushion appearing fabric over it. I would have been more comfortable riding a sybian."
Cons: "The seats suck, the price isn't worth the back pain."

Pros: "Easy access times"
Cons: "No leg room! And I'm only 5'6"

Cons: "Wouldnt let me board, even though i was 39 minutes before my flight time. And $40 bag fee for CARRY-ON?!?! Will never ever fly Spirit again."

Pros: "The quick flight."
Cons: "The rude gate agent, having zero comfort, no complimetery food or drinks, charging me for some unnecessary and something I didn't do, and terrible customer service. Not sure if I'll ever fly on spirit again."

Pros: "Cheap. It Was better than my return flight when they didn't allow me to board the plane."
Cons: "4 hour flight on the worst seat on the plane."

Pros: "Website was simple but online Che k in was cumbersome. Flight crew was friendly. Flight was on time and without issue."
Cons: "First time flying Spirit. Hidden costs were a surprise and kind of ridiculous. After adding back minimal normal travel needs the tickets were not any cheaper. Seats were way too small and no legroom. Will think twice before flying again."

Pros: "They CAPTURE you by their low prices. They DO NOT disclose that there is a charge for everything until AFTER you purchased your tickets -- seats from $9 - $45, every food and drink item, carryon bags for $36 per person and check-in luggage maximum of 40 lbs. for $31 and over 40 lbs is $25. I was better off flying cheaper on another plane. Furthermore, there is absolutely no room space between rows of seats. My daughter's (17 y/o) knees touched seat in front of her."
Cons: "They CAPTURE you by their low prices.

I was better off flying cheaper on another plane. Furthermore, there is absolutely no room space between rows of seats. My daughter's (17 y/o) knees touched seat in front of her."

Pros: "The pilot made jokes about how cheap spirit airlines is."

Pros: "Plane was new"
Cons: "Gate crew were oblivious and unhelpful. Plane was delayed for late flight attendant & bad pilot headset. Most amateur operation I've seen in airline industry."

Pros: "Everything was pretty good. Plane was clean, boarding was fine. I think if you know going in, there are no extras, then you'll be perfectly content. Also, there was more room than expected so that was nice."
Cons: "I have to say the crews going there and back could use a little more professionalism and customer service training. I don't wan't to blanket criticize all of them because I didn't come into contact with everyone of them as much as others, but I was put off by the flight attendants attitudes. They don't help as much as on other airlines and don't pass out food to everyone like on other airlines, so when I do order and pay for it, I expect a pleasant reaction, not to made feel like a burden."

Cons: "Lost bag"

Pros: "I did not know what to expect flying first time on Spirit but was pleasantly surprised at the efficiency and kindness of the employees."
Cons: "I was not pleased to find that the weight for a bag was 40 lbs and was charged $25 on top of the $40 bag fee for an overweight bag. This must have been in the fine print for I did not see it and packed my bag to be less than 50 lbs. The seats have no leg room and I found them to be restrictive for my 5'2" frame. They do not recline due to the space "saving" efforts of the airline. If you are looking for "cheap" remember to add on all the fees charged for bags, select seats, beverages before comparing to other airlines."

Pros: "Flight was on time and boarding process is quick and efficient"
Cons: "Extra charges for everything! Paying for carry-on bags, assigning seats, drinks/snacks, etc. No inflight entertainment. No wifi option etc. At the end, you pay the same (or more) for the flight that lags traditional services."

Pros: "Not much"
Cons: "I paid lots of extra fees for my luggage, and we waited for over an hour and a half for the luggage to come through baggage claim. No one ever announced that there was a problem to let folks know. May folks missed their ground transportation connections. When I tried to find out what the hold up was, I couldn't get through to anyone."

Pros: "Staff at Spirit Airlines at OAK airport were really nice and helpful. Flight was cheap and safely flown - a huge plus for me, but plane not cleaned well and baggage fees were higher than the price of the flight itself so I am very lucky I brought a recognized carry-on bag."
Cons: "For my outgoing flight, my front pocket magazine holder in front was pretty covered in some stain that I couldn't recognize but was sticky to the touch. I knew they hadn't really cleaned the plane. I didn't really open that magazine holder because it was covered by this large stain. My return flight was changed several times due to mechanical issues but I appreciate that Kayak sent updates via email. It was 70% likely not to fly but ended up flying maybe 3 hrs later (good that they made sure to be safe than sorry) but I just couldn't wait to find out overnight that it would be cancelled at the airport, so I had to reschedule my flight for the next day and find housing and transportation again. I overheard other passengers complained out loud even on the initial flight to OAK airport that they would not travel with Spirit again, but I had more issues with my return flight than my outbound flight. All in all, I think you get what you pay for but this was probably not the best experience."

Pros: "Everything went smooth. Cheap."
Cons: "The seats are small and cramped. They charge for all baggage except for a single personal item of something like 12"x14"16"."

Pros: "Nothing everthing was worthless"
Cons: "The poor costumer service and the overpriced hidden fees."

Pros: "Went smooth and without delays, definitely will flight with Spirit again."

Pros: "The flight was on schedule, no tricks or money extortion. No comfort is expected for a deeply discounted fare. It was as promised."

Pros: "I'm a pretty big man n they help get a seat to my comfort"

Cons: "The accents do not recline."

Cons: "it was cancelled"

Cons: "Somehow we missed the baggage fees. I'm used to being allowed a carry on as part of the ticket. In Spirit's case we had to pay $110 additional at check in for our two bags. Laaaaame. Any other carrier would probably have been cheaper. The headrest was too low (in my shoulders, not neck/head like it should be). It's like the seat was sized for a 4ft person. I'm 6ft, which isn't that uncommon. Uncomfortable."

Pros: "Price"
Cons: "Baggage fees. Web site difficult to use. With a few tweaks could be a decent airline."

Pros: "Staff seemed nice."
Cons: "The seats were uncomfortable and didn't recline."

Cons: "They switched gates 3 times in Oakland. In Los Angeles, we waited on the Tarmac for 30 minutes."

Pros: "Standing at the gate waituning to board and 15 minutes after boarding time, flight was cancelled. No Spirit airline workers were even there. About 30 irate passengers had to wxit the boarding area. Went to the front counter and was treated very rudely and never even told us why it was cancelled."

Pros: "I liked nothing absolutely nothing"
Cons: "Delayed 3 hours for a 1 hour flight. They had a bin n made sure everyone's carry on fit into it. If it didn't fit u had to pay 100$ dollars. Cramped plane. No food or drink. Terrible. Never taking again"

Pros: "Not very much."
Cons: "All of my flights were delayed due to plane issues. Also, when I received my luggage bag from the plane.. It was completely destroyed.. The side of it was broken off and the outside was covered in some type of black marks. Not impressed what so ever. Never will fly this airline again."

Cons: "my flight was late arriving to Houston ONE HOUR ... and plan was very noisy and .. PLUS MY FLIGHT FROM HOUSTON TO DENVER FEB 25 WAS OVER 2 HOURS LATE... I AM VERY UPSET SINCE I LOST A WHOLE DAY OF SKINNG WHICH I WAS TRYING TO DO AFTER 19 YEARS LATER .... RUINED MY 4 DAYS VICCATION WITH MY ELDER BROTHER....THEN GOING BACK HOME ALMOST ONE HOUR LATE............................................................................................................................................."

Pros: "Nothing."
Cons: "CARRY-ONS cost money. They cost more money if you don't buy them ahead of time. It costs extra to CHECK IN WITH AN AGENT. The airline is not upfront about any of this. These charges supposedly keep the cost of the ticket low: You only pay for exactly what you want (ie: if you don't have carry-ons, you can get away with paying less.). This is bullshit. They charge for WATER— tap water— on the plane. It is purely a money making scheme. They don't have repeat customers because they are awful. Oh and the seats are tinier than any flight I've ever been on. Truly the worst flying experience of my life."

Cons: "I got an e-mail a couple of hours before my flight saying that the flight was cancelled. However, this was not so. There was nobody from Spirit at the gate giving information, I had to find someone in another gate who was absolutely not nice with customers and just said the flight was OK but did not provide any explanation for the cancellation e-mail. Pretty bad experience at the airport."

Pros: "The new aircraft was nice."
Cons: "The flight attendants weren't very friendly. I overheard one day she doesn't know why people get on the plane and then use the lavatory right away. How about this is a possibility, your flight was delayed 25 minutes and we were in line waiting to board so after we got on the plane and got situated we needed to use the restroom. Maybe she was just having a bad day."

Cons: "First and last time that I'll be flying Spirit"

Cons: "After making the reservation I tried to call to make an adjustment and your website is the worst I have seen in quite sometime and completely worhtless as far as making changes and much less trying to reach someone for assistance. NEVER WILL I CONSIDER THIS AIRLINE AGAIN AND WILL GLADLY TELL EVERYONE I CAN ABOUT IT."

Cons: "I could live with the extra charge od $55 per bag on the Denver to Phoenix portion of the trip, but they cancelled the flight an hour before leaving Phoenix to Denver. This left 100 people scrambling to find an alternative flight. Rather than wait 1-2 hours while two totally unprepared ticket counter clerks tried to accommodate 100 PO'd travellers, I decided to get one of the few tickets available to Denver leaving that day. It cost me $375. I finally got thru to the Spirit Customer Service desk (somewhere in the Philipines?) where somebody did try to help, although the line was sketchy and the accent indecipherable. I recommend not listing Spirit on your site."

Pros: "The good price and straightforward process"
Cons: "The delay but it happens"

Cons: "Delay"

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."

Pros: "It was a short flight"
Cons: "Waiting in the airport for three extra hours for a plane to come for us."

Pros: "Very professional staff"

Pros: "Nothing at all"
Cons: "Every aspect, with the exception of how the employees agreed with all my grievances profusely, and even said they regularly got similar complaints."
