Airline reviews

Pros: "By luck, I had a seat between myself and the other person in my row. It would have been tight, otherwise. Crew was friendly and polite."
Cons: "The seats on the flight were placed very close together - felt very constricting. Takeoff and landing were a bit rough."

Pros: "Really disappointed as my bags was not check thru.It was rechecked at London and British airway charged me for my baggage. I want to make sure that my way back to Oslo London London San Diego has no charge . It is an international flight and I am allowed 23kg one checked bag ."

Cons: "Damaged one baggage, and delayed arrival of other baggage for 2 days that forced me to cancel a following trip."

Pros: "Pleasent"

Cons: "delayed/not on time"

Cons: "3 boarding doors less than 50 feet apart with departures leaving within 15 min of each other created a difficult to penetrate gaggle."

Pros: "The flights didn't have any delays"
Cons: "Seat wasn't comfortable."

Pros: "The flight was great--good food, good service, good entertainment, on time."

Pros: "Take-off and landing were smooth."
Cons: "Was not able to track the progress of the flight on the monitors No entertainment Seats do not provide comfortable leg room"

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: "Wonderful, again. Will fly American any chance I get!"

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: "Poor customer service"

Pros: "AA put us in a hotel and gave $12 (per person) food voucher for missed connection due to delay for maintenance."
Cons: "Our luggage was lost for 2.5 hrs in PHX airport, due to mix-up by service rep at customer service. AA attendant at gate at CLT was extremely rude and unprofessional when I accuse Left my boarding passes in seat pocket. Would not summon someone to retrieve it. Made me wait until entire plane was disembarked and cleaned, and made me wait some more after. She was super snarky, made rude comments, and almost made my family miss our connection to EWN. I will never, ever, fly AA again. Worst customer service and tons of issues with maintenance, luggage handling, and delays."

Cons: "Watched a very weird interaction between Muslim (with a hajib) women with a kiddo and desk crew. She wanted to sit next to her child on the flight and needed to switch seats to be able to. Woman was very gracious and understanding that she was asking for an accommodation. Ends up her flight to Philly had been moved to a different gate after they had found a volunteer to switch seats. Volunteer was totally unfazed but Desk crew made it seem as tho the Muslim mom was at fault for the time and trouble they had had to go through to accommodate her. She apologized profusely and was very appreciative for the trouble evernote had gone to for her. . As she walked away the crew looked at each other and shook their heads. Pretty crummy way to treat customers!"

Pros: "On time departures and arrivals. This domestic first leg of the flight had fairly good leg room and seat width."

Pros: "I initially booked my flight via Kayak for a cheap no hassle price"
Cons: "My initial booking was with Iberia Airlines and a few days prior to my Flight was switched over to American Airlines. Had i known I would be flying with AA, I would have opted for a more expensive option as I've a great disdain for AA. My flight from JFK was not the model aircraft I was promised and thus did not have ac chargers or Wifi in the plane. In my opinion, I was bait and switched via Kayak"

Flight was canceled and they put me on different plane, which make my day in San Diego very difficult, because I miss my meeting, I didn't get better seat ither,instead I got seat in front of toilet and for 3 hours have to listen door bunging and terrible smell. I never been compensate for canceling flight or extra seat price.Nobody care even apologize. I hope that was just unforchened incident and I still like your company and still flying with AA, but I was really disappointed. Sincerely Vera Vasiley."

Pros: "I arrived at Dusseldorf"
Cons: "First flight was delayed 5:30 hours, so I was moved to different flights because I would not have made my connections but those flights were uncomfortable and had bad service and the people working didnt even so much as offer me complimentary peanuts"

Pros: "The flight was on time and boarding went smoothly."
Cons: "Didn't eat or watch the movie. There needs to be an n/a rating available for this review."

Cons: "Im still in dallas.....very angry"

Pros: "I fly alot! I have never been on a plane that was so shaky from take off. No wind nothing crazy effecting the pilot. It felt like maybe it was his first flight"

Cons: "Seats too close not enough leg room for tall people"

Pros: "Flight delayed provided snack in terminal at gate."
Cons: "Flight delayed three hours"

Cons: "I was dissappointed in the additional baggage fees for checked bags and then have to watch people fight for carry-on baggage space. Ridiculous situation airlines have created. Plus flight was delayed because of mechanical problems coming back. But in flight was comfortable and well done."

Pros: "Always. Always. Always"
Cons: "The fact that going to and from New Orleans takes as much time as flying around the planet twice."

Pros: "Although my flight was delayed and I had to take 2 connecting flights to get home my baggage also made it home with me."
Cons: "Seats were uncomfortable. The flight was so loud, it was like driving down the highway with the windows down. AA automated messaging services called me to update me regarding my itinerary change when my 1st flight was delayed and provided wrong information which lead me to attempt to board an incorrect flight causing confusion and frustration."

Cons: "I booked through Alaska and received an Alaska boarding pass that stated the flight was operated by Sky West. To be sure I was at the right terminal I confirmed with the security agent before going through TSA. Once through the disorganized security check I sought out a departure screen but could not find my flight anywhere. I approached a gate agent to assist and he told me my flight was on American, located outside of security and in the terminal I had just come from. He confirmed that despite the verbiage on my boarding pass my flight was neither being handled through Alaska OR SkyWest. I hurried back to the first terminal and asked the security agent but she did not speak much English and could not help me. I then hurried to the American Airlines desk where the woman was also confused. She told me there was a flight to LAX but not operated by American, operated by American Eagle. She confirmed that this was the correct flight and at my prompt gave me a new boarding pass from American. After running back through another very disorganized TSA I finally made it to my gate in time to board. My seat was located next to a woman who took up 1.5 seats and required me to lean into the aisle to avoid touching her at all times. All and all a sub par flying experience."

Cons: "The flight sat on the runway for an extra hour and a half before we took off, causing me to miss my connection flight in Charlotte. Thankfully there was another flight two hours later, however I didn't arrive in Providence until midnight. The real problem was that the connection was delayed to leave at 8pm. We arrived in Charlotte at 740ish. Ran to other side of terminal to reach connection. They already had the doors closed and refused to let us on. There were at least ten passengers who were delayed as well and couldn't make it on the flight. The customer service assistant at the gate was horrible. She didn't pay any attention to us, as we were all out of breath (clearly trying to make the flight). Another gentleman stepped in and put us directly on the later flight. If American knew that there were so many flights delayed, they should have held the other plane a bit longer, as well as helped us out immediately. Not impressed."

Pros: "Professional, punctual good flight"
Cons: "Like on domestic flights limited service."

Cons: "Had to check my bag because they ran out of overhead bin space."

Pros: "I was comfortable. I entered and exited the plane very fast."

Cons: "The change of flights. Had to stay in airport overnight!"

Pros: "It gets you from point A to point B."
Cons: "By the time you add a bag, you can fly another airline. And if you're over 6', it's not worth it. I'm 6'4", and my knees touched the seat in front of me for the whole flight. Seats don't recline, so I couldn't adjust at all."

Pros: "Good flight. Accommodating. Will fly again. Cheap flights"

Pros: "Very professional staff treating passengers with respect Planes were clean and on time"
Cons: "Seats were horrible. Only first three rows recline and they were much more expensive to book. I left the flight very fatigued. Last flight of the day the cabin pressure was off so kind of hard to breath. Both my wife and I experienced this. Overall I think the lack of comfort would make me search for another airline next time unless they improve."

Cons: "I don't like getting nickel and dimed. Baggage charges are standard nowadays, but I was shocked that I have to pay to carry a bag on the plane AND it was more than for a checked bag. And I had to pay for an assigned seat for each leg of my trip. Wow! My first and last Frontier experience."

Cons: "Lack of entertainment options"

Pros: "The flight was late.."
Cons: "You pay for the flight and then pay for everything on the plane"

Pros: "1 flight canceled, 2 delayed due to their aircraft being broken. Lost my luggage and overall the staff was angry and rude when I asked for help getting my stuff back. I will never fly frontier again"

Pros: "Nothing"
Cons: "Why should anyone want to book a flight only to find out that the ticket price doesnt include a seat................. for a seat there's an additional charge. And then a charge for a carry on bag of $40. Your airline is ridiculous!"

Pros: "Cleanliness"
Cons: "Very uncomfortable. Wouldn't want to fly a longer flight. When we exited the plane we were stuck in the hallway between the plane and the airport door for 20 min. There was no one to unlock the door. Passengers were starting to panic. Someone called 911 to get us out. Terrible experience."

Pros: "I'm 6'3" and simply cannot get comfortable in a plane seat."

Cons: "First of I got double charged for my bags second flight delayed for no reason n seats are extremely uncomfortable we arrived n we stuck in the airport for 30 mins no reason bags took an entire hr so I just left my bag"

Pros: "On time, cheap"
Cons: "Have to buy water"

Cons: "I didnt like how i had to pay $105 for a carryon for going there and back. Thats ridiculous! I can understand the initial price at the checkin gate but that price shouldve been covered for the roundtrip. I will never fly Frontier again. And ive told several ove my friends and family not to fly with that airline either. The reason why they are so cheap was because they will find a way to get you in the back end of the deal. I couldve flew with American airlines with no layover and not have paid a fee for a carry on. Wouldve been at my destination faster and no hassle."

Cons: "Seats are super uncomfortable they dont recline at all!! , A drink cost 2 dollars you have to pay 45 each way for a Carrry on!! Next time ill pay a little extra and atleast get to have a carry on reclining seats and a complementary drink ! it ends up costing the same but atleast ill be somewhat comfortable ! Never again will i fly Frontier its not worth it"

Pros: "NOTHING"
Cons: "charged me 40 for check in and 45.00 for carry on bag... Also charged for drinks and chips... seats were hard and terrrible"

Cons: "There was no tv."

Pros: "Got home from San Diego, Ca."
Cons: "Seven hour layover in Denver. Flight started out one hour late and then the Air Conditioning on the plane did not work putting us another hour late leaving."

Pros: "Pricing was very reasonable. Flight crews were, for the most part great, although I was a bit put off by one attendant who chewed gum throughout the entire flight."
Cons: "Severe weather in Denver caused significant delays for departure and while I realize that the weather was the major factor, changing gates several times in a large airport for departure made Frontier look as if they were not prepared for events such as this. On the return flight, we arrived early only to find there were no gates available for deplaning."

Pros: "seats were some what comfortable"
Cons: "did not like the fact that I had to pay extra for a seat when I already purchased a ticket"

Pros: "Getting off the plane."
Cons: "Frontier is all around archaic in a modern world."

Pros: "Nothing"
Cons: "Awful customer service across the board. I have flown Spirit regularly, so I am familiar with the concept of the low price airline, but this is far worse than anything I have ever experienced with Spirit."

Pros: "not much"
Cons: "fees for everything, new plane but hard seats, no screen, tiny useless tray tables, and flight was 2 1/2 hours late. the fees were the worst part, however -- next time I'll factor in an extra 100 bucks per ticket when I'm comparing prices to cover all the fees."

Pros: "The flight was cheap"
Cons: "Flight delayed 3 hours due to technical difficulties. Was forces to pay to check my carry-on because it was considered a "duffle bag". Screaming children the entire return flight not even seated. Cramped quarters. Terrible"

Pros: "NOTHING"
Cons: "They cancelled my flight. Soonest Frontier flight they could re-book me on was EIGHT DAYS LATER. They have no agreements with other airlines to book cancelled passengers with. They would NOT pay any hotel expenses. It was left to me to find alternate transportation home as well as book a hotel room for the night and pay for it. This was the absolute worst airline I have ever flown on in all my years of air travel. Did I mention that they even charge for the in-flight soft drink? Oh yeah, The seats don't recline, none of them."

Pros: "Nothing"
Cons: "Seating because the seats don't recline and the leg space was basically non existent. First experience on Frontier and unless they make changes for some kind of comfort then this is definitely our last!"

Pros: "cheap fare"
Cons: "The new seats were very uncomfortable for such a long trip. Too close together. BTW I'm 5'1" and weigh 100 lbs. paying for a very limited choice of unhealthy snacks"

Pros: "Really appreciate the free check baggage for military. The fares are good."
Cons: "The airline charges for everything except water. Seats do not recline at all."

Cons: "The seats are extremely uncomfortable."

Pros: "Easy check-in & baggage drop"
Cons: "Seats were stiff and did not recline No neck support for snoozing ..."

Pros: "There's nothing bad about Frontier's service. Flights were on time, staff was courteous."
Cons: "BUT, they don't honor Global Entry or TSA Pre-Check, which is ridiculous! The ticketing agent told me "it's not in the budget." Had I known this ahead of time I wouldn't have purchased a ticket from Frontier. The security lines were incredibly long in Denver and this added a good 30 minutes to my passage through the airport."

Pros: "I didn't have to pay extra for my seat with extra leg room"
Cons: "There was confusion about my seat"

Pros: "Arrived early"
Cons: "Had to pay for seating"

Pros: "Crew was great"
Cons: "Small seating"

Pros: "Cheap cheap cheap flights even with paying for a checked bag our total round trip for 2 people was less than $160. We knew frontier was a bare bones plane ride. We had no issues with everything. The seats were a little uncomfortable and the trays were about the size of a check book but other than that the flight was fine."

Cons: "Did not have any food or drink"

Cons: "No help from ANYONE from this airline!!!!!!!!!!!!!!!!!!!!!!!! What's wrong with you people??????????????????"

Cons: "I had the flight from San Diego to Denver then we stopped at Las Vegas because of some who had heart attack. I had a meeting at that day I couldn't attend because we were at the airport of Las Vegas from 9 to 2 pm looking for a flight going to Washington DC. They found a flight from Vegas to Denver then to DC but they lay over is 15 hours in Denver and I couldn't wait because I had an appointment for my dad in the next day in the morning for dialysis. So I had to reserve another flight from Vegas to Baltimore directly. And I paid that. Also, there was a lady who checked in the luggage in San Diego. When I was checking in my luggage she told me to pay 30 dollars for my bag while there was another family after me and she didn't get any money from them for their luggage and she checked their luggage for a free. This UNFAIR and impolite. So I need all of my money back also the difference that I paid for the new ticket and luggage. Thanks Wafa"

Cons: "they cancelled the fligh on me - over booked"

Pros: "The crew are nice people, and it got me from Denver to San Diego and back. Relatively inexpensive."
Cons: "I'm tall (6'4"), there's no leg room, and the head rests aren't actually tall enough for me to sleep on. So, not super comfortable. I didn't expect anything more really. It just sucks that air travel forces premium prices for basic comfort."

Cons: "Crew was not very friendly, seats are not comfortable, and baggage is too expensive."

Cons: "Frontier is the worst airline ever. Make it look like a cheaper fare but charge you for every possible thing they can. Your seat, drinks and even your damn carry on bag. NEVER AGAIN."

Pros: "The handle on my suitcase was broken sometime between check-in in San Diego and arrival in Madison. Agent didn't know how to file a claim. Later supervisor took over as nd told me that "handles and zippers are not covered for damage." She held up a paper and told me it was in the fine print. The least they could have done was at least refund the $40.00 baggage fee. Bad news poor training . Easy fix but they missed it Joel A."

Cons: "The crew on the ground in Denver were not able to get the walkway up to the plane for at least 20 minutes after we landed. The luggage was really slow too. left the airport 50 min after the plane landed and was at the gate. Online there was no option for not purchasing a seat at check in. Deceptive pricing and policies. I did not know it was an option to not pay extra for a seat."

Cons: "Ridiculous amount of room,so cramped. You used to do well, costs for baggage too high...1 hour late start...on time commercials are false. Will not fly frontier anymore. Very disappointed!"

Pros: "I would like a free snack and drink. The stewardess passed over me when asking for a drink."
Cons: "We had to pay for a drink."

Pros: "The flights were short and the passengers were nice."
Cons: "I understand that Frontier is trying to minimize flight price by charging independantly for everything, but they take it to the extreme. Charging for a carry-on and choice of seat (including a middle seat) is a bit ridiculous. The plane seats were not comfortable and did not recline. I would not recommend Frontier to anyone because the flight price plus the add-ons did not make Frontier any cheaper than a comfortable airline."

Pros: "The staff was very nice/pleasant."

Pros: "Customer service during flight check-in was great, quick, friendly and efficient"
Cons: "Overall attitude of main female flight attendant, simply condescending and overall rude."

Pros: "Seats and space we're awesome"

Pros: "Both flights, Denver - San Diego and San Diego - Denver left and arrived ON TIME! Very happy"
Cons: "For a 98$ flight including insurance I guess the only thing I can complain about is the 50$ checked bag fee. But still was a decent deal."

Pros: "Right on time and made me feel comfortable"
Cons: "Nothing I didn't like"

Cons: "Very uncomfortable ride. We a t-shirt hard ,zero leg room"

Pros: "Nothing"
Cons: "my ticket was $53 and had to pay $50 for my bag. If I would've known they'd charge double I would've chose a different airline."

Cons: "Changed time to one hour later than time posted at check in."

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

Pros: "Clean airline. Nice staff."
Cons: "Very little leg room."

Cons: "Flight was 2 in a half hours late"

Cons: "I cancelled my flight, but still received this, interestingly! I had no idea when I booked that even a carry on suitcase would cost extra! I was so angry, and nothing could be done. Therefore, I cancelled the flight at an additional cost and booked with Southwest, who is extremely generous with baggage accommodation. I was very happy with Southwest."

Pros: "Landing alive"
Cons: "Everything"

Pros: "Ended up with 1st row which was great. Plenty of room."
Cons: "Unfortunately that put me front and center for the flight attendants catty behavior. They opened the bathroom door on two people, a child and an older man. Then proceeded to spray deodorizer outside the bathroom door and snicker. When the cart went around no one ever asked me or the guy in 1a if we wanted something. Just skipped us completly."

Pros: "I really liked the stewards and stewardesses,the smooth on time flight was also great!"
Cons: "That I was given a 7.00 food voucher because of all the problems and the 4-5 hour delay,but I was unable to use because it expired. We were given the credit right before being put on the plane,so we were unable to use it that day!"

Cons: "the system for online check in has been down since i took a flight with Spirit last month. To have to wait in a long line to print a boarding pass with no checked bags is beyond frusterating. All the nickel and diming and unnecessary waiting puts me in the mind set to never fly Spirit again, it ends up bring the same amount of money and way less hassle to just go with another carrier."

Pros: "The planes are new and comfortable."
Cons: "The flight attendants serve almost no purpose. You have to pay for everything and almost everyone doesn't want to spend extra cash on food and whatnot. So I found the flight attendants just spend their time gossiping loudly at the front of the plane."

Pros: "I liked the crew"
Cons: "I did not like that my flight kept getting delayed and they provided late notifications"

Pros: "not much"
Cons: ",having to fly back home on it"

Pros: "Spirit sucks big time"
Cons: "Bad bad bad"

Pros: "I loved the price."
Cons: "The plane was delayed by 45 min then 2 hours. Don't like waiting personally."

Pros: "That it got us there safely."
Cons: "Flight attendants were not friendly. Felt they should smile more."

Cons: "Flight was cancelled due to mechanical issues at 1030pm after waiting for 4 hrs. We were all sent to the front desk, got there, and no one came to help us for 30 min. The guy from the gate actually had to come up, I felt so bad for him. He gave - few people at the front of the line cards to call to rebook, but the phone number didn't work so I just called the help line. But most people didn't know and weren't told they could do that. Instead the guy helping us had us form two lines, one for rebooking and one for refund that didn't move for the next half hr. They didn't tell anyone in the line they could call someone so they just waited. The worst is that they told everyone Spirit would not be offering accommodations. It really seemed like a "we aren't going to deliver the product we promised and good luck figuring out what you'll do now." By the end of it, I was just happy to get a flight for the next night. I'm not sure what happened with everyone else once that flight was filled because there were no others. Between the astronomical bag prices and the worst customer service I've ever seen, I won't be flying with Spirit ever again."

Cons: "Never happened- call center - no one actually does anything. 1:30 hours on the call - never received conformation."

Pros: "-The employees are very friendly and helpfull."
Cons: "-everything cost extra -only 18kg allowed (other airlines minimum 20kg, for FREE!!) -only 1 personal idem (other airlines at least 2) -Extra bags (also suitcase) are really expensive!!! -it cost even more if you don't check in by yourself -even if you want to sit you have to pay, should I stay in the airplane???? -water in the airplane cost 3dollars!!!!! (other airlines for FREE, PLUS snack!!!!!) -on my site (WHICH I PAID FOR!!!!!) were used tissue!! -worst airline i've ever flew with! never again!!!"

Pros: "The plane got me to my destination and back without major incident"
Cons: "I bought my ticket through Kayak thinking what a great deal! But what I didn't know is that they would then nickel and dime you the rest of the way. When I went to check in I found that I needed to pay $40 if I wanted to bring a carry-on (each way! I suppose it's possible I was going to leave my bag somewhere?) and then had to pay to pick a seat. None of the seats were actually free, which leads me to believe my original ticket price was like a cover to a very overpriced and boring club. Nothing else is included, not even water, so either prepare to pay onboard or be well-stocked (but not too well-stocked, because if your bag is over weight you have to pay more.) The planes themselves were old and rickety and made some weird noises, which didn't inspire much confidence. The spirit credit card was pushed on me multiple times through my online check-in, my additional seat/bag purchases (note: don't offer someone a credit card while they're already annoyed at your company) as well as throughout the flight. I finally fell asleep only to be woken by a long, blaring pitch to sign up for a credit card. This was my first and last trip with Spirit."

Pros: "there was really nothing I liked, would never fly Spirit again."

Pros: "The price was great. I pack light and take advantage of the "bare fare" offered. Flight was uneventful which is how it should be."
Cons: "I would like to see a more streamlined process for checking the baggage rather than waiting in line. My wife checked a bag so we had to wait in line right as we arrived. Was hoping this "hands-off" approach would streamline the waits in line."

Cons: "So late!"

Pros: "The T-Bone steak was done perfectly...5555555"
Cons: "It was the worst bus ride ever!"

Pros: "Crew was great"
Cons: "It was just an ok but cheap flight. Thank you for low prices!!"

Cons: "the flight attendant was extremely annoying, being loud and almost putting on a show, it was the worst. he kept getting on the intercom and saying dumb comments. what topped off this annoyance was that they didn't even offer the passengers water, you had to buy it. i was seriously parched by the end of the flight, so bad."

Cons: "Late and delayed constantly"

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

Cons: "Flight was cancelled for mechanical errors. Offered cash back to fly another airline (Spoiler: wouldn't cover cost) or wait 5 days for next available flight. Not acceptable."

Pros: "Cheap"
Cons: "Small seats"

Cons: "Hidden fees and delays in takeoff poor customer service"

Cons: "Really late departure without knowing why. We were left unsure if the flight would take off and given the option for a refund or get on the next flight the next day"

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

Pros: "If another plane is broken down in our spot figure out an alternate plan before we land so we can deplane in an appropriate timeframe. Think and plan ahead."
Cons: "If u have not guessed yet... The above answer is for what I did not like."

Pros: "Nothing"
Cons: "Had to cancel trip because flight was delayed 3 times, and was going to get into Denver at 3 am when originally supposed to get in at 10:30p"

Pros: "pricing was good"
Cons: "seats were very close. sound travels"

Pros: "The crew was nice, but have little to do during the flight."
Cons: "The seating in the $10 seats is terrible. Too close quarters to the seat in front, the seat bottom is too short, and hard to stretch out legs. I am a small woman and it was too tight for me.....not to mention the tall, heavy people behind me.. Whew!"

Pros: "Because of blizzard was cancelled. Took three days and hours to get another flight. Some on phone were not at all knowledgeable"

Pros: "I liked the leg room"
Cons: "Horrible customer service.... maybe spirit should raise everyone salary because the entire crew looked out of it .... absent minded. That's not the spirit. No pun intended! Flight cancelled. Because a flight attendant didn't feel well. Replacement flight both delay by more than an hour each. I was treated like a thug until I showed my military ID ...that's sad"

Cons: "The plane smelled overwhelmingly like urine."

Pros: "The price was great."
Cons: "The great price means basically no amenities. That's okay, I'll take the cheap price."

Cons: "The plans are to packed, and the hidden fees!!!!"

Cons: "The passengers and the seats are very uncomfortable"

Cons: "Too many delays for too long each time. This was the worst flight I have ever been on."

Pros: "The price"
Cons: "The customer service was so terrible I would rather pay more to be in a more respected a irline. Never again and I will tell everyone I know about my experience how your staff handled the situation."

Pros: "Called Spirit Airlines several times to inform them that I could not fly due to medical reasons, but to no avail. Seems there is no one qualified to talk about medical decisions. My phone number is 619-890-6979 Hopefully, someone will call to resolve this matter Sincerely Barry Huntoon"
