Pros: "Nothing."
Cons: "Everything"

Pros: "We didn’t crash and die. That’s the only positive."
Cons: "Before we boarded I listened to a couple described how they always went ahead in line at boarding because no one ever stopped them. They described how they waited until group 3 was called and then went right through. While we were waiting, we watched them do it again. If you need to cram people into tiny spaces to be profitable, then you cannot allow them to make it worse by putting back their seats. I spent 90 minutes with a seat back jammed into my chest. We were ignored when handing out snacks, probably because we were invisible behind the seats pushed in our faces. It was one of the most miserable flights I’ve experienced."

Pros: "Nothing"
Cons: "Had to change our plans, and AA wouldn't give us a refund. We never got on the plane but had to pay for the tickets anyway. I'll never fly AA again."

Pros: "We were allowed to board early with my father, who is disabled."
Cons: "Denver airport was a nightmare with my disabled father. We were given a “wheelchair” but no escort through a nightmarish security scene.

Cons: "Was delayed a lot"

Cons: "The flight was delayed which caused us to miss our flight in London our family was delayed for 12 hours"

Cons: "prefer having tv screens in the seatbacks as opposed to using my tiny phone as a viewing screen. only food available besides pretzel was pay food."

Pros: "The plane was super comfortable"
Cons: "Long check-in lines in Denver - there were two sky caps outside who had no line which allowed me to reach my gate in time. Otherwise I may have missed my flight"

Cons: "Try to be on time!"

Cons: "If we had access to the WiFi to watch shows earlier like United does, that would be nice."

Cons: "We are delayed 7.5 hours dues to mechanical issues with our plane and told we would have to wait or book another flight the following day. American Airlines sucks!!!!"

Pros: "The flight was on time."
Cons: "The seats are absolutely horrible. I feel crammed like a sardine in the plane. Seriously, can we adjust the seat widths and distance to the seat in front and make them a couple inches bigger?"

Cons: "I have changed flights. Been delayed 5 times now. And still haven’t left the USA."

Pros: "The crew was very friendly and accomodating."

Pros: "We were rerouted through Philadelphia."

Pros: "Great service, friendly staff. Plenty of in-flight entertainment options"
Cons: "N/A"

Pros: "Free in-flight entertainment. Like that in-flight entertainment is available on users device, rather than screens in headrests. Staff were courteous and friendly."
Cons: "Flight delayed d/t computer glitches and problems in NC. Once we eventually boarded, we were forced to check our carryon luggage d/t lack of space."

Pros: "Good is that they sent you to Finnair to correct AA created break in service...why would they pay for it? AA is just an operator per itinerary! Why would you care if ppl get help with connections!"
Cons: "Checked in online on Finnair and automatically for the second connecting flight...and not the first -AA. So, had to check-in again for the first flight at the terminal. Board passes were printed 2 out of 3 by AA and both had errors - wrong gate for the first flight and no boarding info for the second connecting flight - just blank! AA did not provide connecting info until I found an unoccupied employee at the terminal and customer service lines were about 20 people in 2 locations I went to. The connecting info should be in the itinerary they said at customer service...nope, it was not there either!"

Pros: "Nothing"
Cons: "Broken plane, re-route and conflicting inaccurate email updates."

Pros: "Great service."

Pros: "The helpful steward"
Cons: "The bumpy ride"

Pros: "fairly comfortable, crew was helpful"
Cons: "Having to use my phone for entertainment, with no place to plug it in"

Cons: "I'm not sure where the problem was - whether with AA or Royal Jordanian, but my luggage did not make it to Amman with me. In fact, there was a whole group of passengers traveling on American from different US cities, switching to RJ in Chicago, whose luggage did not come on the flight to Amman. My advice: be sure to pack enough for a couple of days in your carryon - and don't accept an offer to check your carryon to its final destination!"

Pros: "Comfortable seats, good legroom."
Cons: "Not enough coffee for breakfast."

Cons: "This was a BA flight on an American Airlines plane. Very small crowded and uncomfortable. My husband is 6'2" and barely fit in the seat."

Pros: "The crew was awesome."
Cons: "You guys lost our luggage!"

Pros: "Quick and easy boarding"
Cons: "Uncomfortable seats"

Pros: "Everything ran smoothly despite turbulence and bad weather, thanks to the crew."
Cons: "Seating is even more cramped than I'm used to, and everything outside of a drink and a biscuit is extra money."

Pros: "Nothing"
Cons: "Everything"

Pros: "There was nothing too bad other than I wasn't able to check in online bc our first leg of the flight was operated by American Airlines. But there wasn't anything that really stood out that would make me want to fly them again other than it was the best price."

Pros: "Very nice and showed concern for safety. That made me feel good."
Cons: "No in flight DirecTV"

Cons: "Not leave 2 hours late"

Pros: "The counter for UA was not attended. I had to make few calls and they managed to put me in the next flight via Chicago"
Cons: "Reality. Flights are sometimes delayed and bound to miss connection"

Pros: "I missed my flight due to a delayed flight from denver to Washington. When I arrived I beg if there is a sooner flight to Geneva. They said no more. They book me another flight which has more connections. When I was waiting for my next flight there were actually more flight going and direct to Geneva before my flight. I even ask the gate personel if There is more seats avilable for one of those flight before my flight. They said yes but because I had a luggage it will take time to transfer my luggage and they will end up being delayed. United airlines is HORRIBLE!!! My flight were delayed and with that they should have more consideration for those costumers who were delayed. But instead of being kind and considerate. They had book me a later flight and the worse thing is the itenerary had more connections. Very Exhausting. The other costumer when we were in the line at the costumer service desk some people were given flight which are like 12 hrs away. How Horrible service. I WILL NOT FLY WITH UNITED AIRLINES AGAIN. Very POOR SERVICE."

Pros: "Read above"

Pros: "The crew was friendly and patient"
Cons: "The seats aren't very comfortable, but it was a short flight"

Pros: "Much more room, seats are more cushy"
Cons: "Delay"

Pros: "It was okay."

Cons: "I was very cold!"

Cons: "I was allowed only 1 bag to carry on when both my bag & purse would have clearly fit underneath the seat in front of me. Makes no sense. Also other airlines don't require you to check in at the counter if you're not checking a bag. Why would United want all passengers at their ticket counter or kiosk? Ridiculous!"

Pros: "We arrived on time"
Cons: "The ticket clerk up charged me stating that my carry on was over weight and insisted the bag be checked. When I inquired why, the ticketing agent became indifferent stating that they would not issue a boarding pass because they were not dealing with questions. Had to pay and pacify the agents rudeness or be denied a pass. What happened to this airline?"

Pros: "An attractive, attentative crew"
Cons: "Snacks sucked"

Pros: "Everyone was friendly, flight was on time checking in at kiosk was very efficient no complaints . I would recommend Kayak and United to friends and family"

Pros: "As long as United still provides snacks and doesn't charge for carryons I will definitely be flying them again. Their staff was great, the flight was a bit turbulent but everything g was great otherwise."

Pros: "Had space on plane nice staff"
Cons: "Still price on wifi and snacks"

Pros: "I haven't flown United in quite some time and Im not sure why but I can tell you that this was by far the best airline service I have received in many years. The staff was friendly and accommodating. I will fly United as often as possible going forward."

Pros: "All around great service for everyone"

Pros: "Even though the flight was a little delayed, the crew really did their best to get everyone boarded as quickly as possible! They were all very nice, and the little snack was delicious!!"
Cons: "It really was a positive experience. Like I said, the flight was delayed 45 minutes, but it really wasn't bad at all."

Pros: "I would have rather of not been offered"

Pros: "Ok, since United now serves complimentary Illy coffee, it is much better!! Thank you for the great improvement. Sometimes it's the little things that make a big difference!"

Pros: "Able to sleep the whole way"
Cons: "Nothing in particular"

Pros: "Being extremely punctual."
Cons: "Nothing!"

Pros: "It was on time"

Pros: "Do delays everything when smoothly"
Cons: "Took a little long for baggage to be released"

Pros: "Same as above"
Cons: "Same as above"

Pros: "Same as above."
Cons: "None"

Pros: "Everything."

Cons: "STINGY DRINK SERVINGS TINY SNACK BAGS"

Cons: "Long waiting time to get luggafe"

Pros: "It got me home."
Cons: "The flight was delayed by more than two hours. I had a two hour drive after which got me in bed at 4:30 AM instead of 1:00 AM. Had to work that day which made it hard to function. Usually great, but was disappointed they didn't offer anything to us for such an inconvenience."

Pros: "Great service"

Cons: "Had to check my bag"

Pros: "Everything was great"
Cons: "No complaints"

Pros: "All the rest was good"
Cons: "Boarding crew"

Cons: "Paid for first class, didn't get offered dinner"

Pros: "Same as above statement."
Cons: "Pilot landed the plane a little on the rough side. The Tarmac was definitely felt."

Pros: "Loved the amenities."

Pros: "Staff and Pilots did a great job. Wheelchair was much apprecciated!!! Everything was on time or ahead of it. Great landing!! Wish you didn't charge for baggage and would like better snacks--oh for the good old days!"

Pros: "The landing was not good as we had turbulance. Other than that, everything was good."

Cons: "The only snack available was a mix that had dairy. Other airlines, like JetBlue not only have a selection from which to choose, but at least one option is vegan."

Pros: "Great stewardess"

Pros: "Same"
Cons: "Same"

Cons: "Horrible flight delayed an hour and the. Waiting an hour for my bag to learn it didn't make flight even tho I was at ther airport 2 hours before flight left. They said couldn't deliver it until the next day so had to go back to the airport to get my bag! Horrible experience !"

Pros: "Spacious!"

Cons: "I HAVENT EVEN GOTTEN THERE YET!"

Pros: "The crew was friendly, boarding was efficient, you got a whole can of your preferred drink without request."
Cons: "Not a lot of leg space, the trail mix snack(ranch flavored?) was gross."

Cons: "No beverage"

Pros: "Cheap airfare."
Cons: "The entertainment and small charges."

Pros: "Nothing. I almost missed my brothers funeral and my wife DID miss because they canceled the flight and never let us know!!"
Cons: "Abominable customer service. No flight no communication"

Cons: "Cabin pressure was terrible."

Cons: "Plane was scheduled to depart at 8:20 pm it was then delayed until 8:58 pm due to weather. We all boarded the plane and were ready for take off when a maintenance issue was discovered. We all deplaned and we’re told we would be put on a new plane arriving from Seattle set to depart at 11:30 pm. This departure time was delayed until 1:35 am and then 2:35 am because the captain had timed out and we would need to wait for a new pilot. Also due to the first delay everything was coded as “weather” and customer service was unable to give hotel rooms. This miscommunication between corporate and passengers and the late night created lots of frustration. Instead of being helpful or honest customer service called security on the disgruntled passengers. I heard no threats of violence just elevated voices. At midnight Frontier began handing out meal vouchers (15 dollars to McDonald’s) as a way to increase morale. I finally gave up and requested a refund, got a hotel, and a new flight on a different airline (all Frontier flights the next day were sold out). When I asked what would happen to my checked luggage they said it would be sent to Dallas (my destination) or I could pay for it to be sent back to Denver. The flight and my luggage arrived in Dallas at 5:30 am. Paid $400 for Southwest flight the next day (flying into different Dallas airport away from my parked car and luggage) just for the guaranteed service."

Pros: "So you got me from point A to point B."
Cons: "Uncomfortable seats. Overpriced fees for carry on luggage."

Cons: "Nothing, the whole trip booked through Kayak on Kiwi was a disaster."

Pros: "Everything well"

Pros: "The personal is berry frendly"

Cons: "I had pre checked in but when I got to the gate (on time for the flight but late in the boarding process) they didn't make an announcement for last calls or for any checked in passengers so I missed my flight. They were changing over the signs for the next flight, so it still read my destination, but the time was an hour later so I thought it had been delayed."

Cons: "I do not feel I willl fly Frontier again. The crew was nice and flight fine. However, the way you nickel time your passengers is beyond awful. How unfriendly can you be!"

Pros: "the beginning price - maybe?"
Cons: "I got to the airport in Dallas 2 hours before my 6:55 flight, and at that very moment, received a text that the flight was delayed 3 hours. At that time, there was NO ONE at the Frontier check in to explain what was going on. I understand there was excessive wind in Denver, but there should have at least been a Frontier representative at the gate in Dallas. On my way home, again the flight was delayed by an hour because of something on a previous leg. Because of this, I am going to go with any other airline first. I think Frontier should either co-op with other airlines to get people to their destinations on time or have more planes.......or AT LEAST have someone at the gate to offer next day service or a voucher or a free snack or something. I also do not like the whole A LA CARTE theme with this airline and Spirit Air. I do not like that I was going to be charged for a coffee or a coke. The whole thing is too confusing, and I am going to pay more for an American, United or Southwest flight next time."

Cons: "Flight was delayed in increments and ended up being 2 hours late. No communication to let us know what was going on and when swoke did come on the speaker you couldn't understand anthing she was saying."

Pros: "the flight attendants were very attentive"

Pros: "Cheap flight! and we did get a voucher for the delay."
Cons: "Five hour delay, I think mostly due to weather."

Pros: "This was my first time to fly frontier... and probably my last. The fact that you have to pay to do everything puts this as a more expensive airline without any of the benefits."

Cons: "Not on time. The contract crew that loaded luggage took 45 minutes to load after we had boarded the plane. At 80 years old, the flight attendant who was still wearing her new years eve hat and looked like she was hung over, did not offer to help after I lifted the carry on and it started to come back out. Not to worry I did it my self. Charge for water!!! Will never fly Frontier again -- even the pilot said it was not the Frontier that he went to work for. Will never fly them again."

Pros: "On time smooth take off and landing friendly service"

Pros: "The crew on my flight from Dallas to Denver did nothing about the obnoxious children (6 & 9yrs old) behind me who kept screaming, yelling & kicking my seat & the one next to me. The little boy behind my neighbor stood up & hit the man on the head."
Cons: "While waiting on my flight in Denver to go back to Dallas they changed gates on at least 5 different flights & it was very confusing watching groups of 50-100 passengers moving back & forth. This all happened in about 15min & my flight was called to board during all this chaos but because the woman making the announcements did not speak very good English I along with several others missed our flights. When i went to customer service to rebook my flight they tried to charge me $100 to rebook!!!!! Other airlines will try to book you on the next available flight thru another airline. Frontier told me the next available was 24hrs later, same time the next day. I was supposed to be back at work the next day. So i ended up spending $150 on a hotel room that i couldn't really afford. I WILL NOT FLY WITH FRONTIER AGAIN."

Pros: "I like that the seats are thinner without a lot of padding. It gives more leg room. I like that my knees aren't hitting that seat in front of me. That crew was very nice."
Cons: "I don't like having to pay extra for my luggage. One bag should always be free and extra bags should be paid for. Paying for water is bad too. Water is cheap. People would buy a snack if they get free water. The fold down tray is also too small."

Cons: "The food trays are spring loaded. This is the worst idea! Kids sit behind you and flip the food tray the entire flight. Frontier should remedy this."

Cons: "I paid for seat selection to have 2 seats by ourselves but Frontier changed the type of plane and it changed the seats to an aisle and a middle seat, exactly what I was trying to avoid. The flight attendant said I would have to talk to the gate agent but we had already boarded so of course that was impossible."

Cons: "THE FLIGHT KEPT BEING DELAYED ALL DAY AND THEN IT WAS CANCELLED. PASSENGERS HAD TO SECURE OTHER FLIGHTS TO THEIR DESTINATIONS. SOME EVEN MISSED IMPORTANT EVENTS LIKE FUNERALS, CRUISES APPOINTMENTS, ETC. I WAS A DAY LATE FOR MY EVENT. I THINK WE SHOULD HAVE BEEN TOLD IMMEDIATELY SO WE COULD HAVE MADE OTHER ARRANGEMENTS EARLIER. I WAS NOT A HAPPY CAMPER AND WILL NOT CONSIDER FLYING FRONTIER IN THE FUTURE!!!!!!!! THAT WAS MY FIRST AND LAST TIME TO PURCHASE TRANSPORTATION FROM FRONTIER AIRLINES."

Pros: "I was transported safely from point A to B. That's about it."
Cons: "Check-in was atrocious as we watched the clerks migrate from one crisis to the next, and no TSA pre-check. WAITING at every stage of the flight. You would think a one-way would be simple, but no. An hour at the departure terminal, delayed in-air, then sitting on the taxiway for an hour and a half at the destination, followed by more waiting at the gate. The pilot's excuses didn't help any, clearly trying to avoid an onboard riot for a flight in which we waited longer on the ground than we flew in the air. We checked the board afterward to see if any other airlines' flights were delayed--nope, only Frontier, every one. It's clear what happens. They pay the least possible expense for airport services, and are then the lowest priority at every stage of operations, resulting in delays at every phase of flight. The most frustrating flight I've ever had that didn't include actual incompetence or bad weather."

Pros: "I was stuck in the Dallas airport for 15 hours. The plane was broken waited on s part and was delayed and finally canceled. Scheduled to leave at 6am finally left at 8:05 pm. I was stuck in the Dallas airport for 15 hours. The plane was broken waited on s part and was delayed and finally canceled. Scheduled to leave at 6am finally left at 8:05 pm."
Cons: "I was stuck in the Dallas airport for 15 hours. The plane was broken waited on s part and was delayed and finally canceled. Scheduled to leave at 6am finally left at 8:05 pm."

Cons: "Checking in / dropping off bags: pulled many out of line to go ahead because they had obviously shown up late. Long line"

Pros: "Same as above"
Cons: "Same as above"

Pros: "All was exactly as expected on the budget flight."
Cons: "The lack of space. I felt crowded and the person next to me smelled making it uncomfortable in such close proximity."

Pros: "Made the trip safe"
Cons: "Seats were uncomfortable."

Pros: "Nothing."
Cons: "The ticket taker at my gate was very rude and did not give any information about my flight. Even one of the flight attendants was rude. Plus, my gate on my ticket was wrong so I almost missed my flight."

Pros: "Nise peaple"
Cons: "Bad weder"

Pros: "Nothing."
Cons: "I didn't know I had to pay for a carry-on bag upon arrival. That's an additional $45 I didn't know about. There was a 4 hour delay and no clear explanation as to why. There was never an agent at the desk when people tried to ask. Our gate changed 3 times. Overall an awful experience and I will never be flying Frontier again."

Cons: "There was a delay of over an hour and half. Boarding process was pretty terrible."

Pros: "All Awesome!"

Pros: "In every way"
Cons: "A to Z"

Pros: "One of the attendants was courteous and entertaining. She made the trip that much more enjoyable."
Cons: "Price of drinks and snacks. I was disinclined to order anything, and kept to myself."

Pros: "The best part about the flight was when we landed in Dallas."
Cons: "The most uncomfortable flight I have ever been on. The seats were very hard and could not adjust. There was no information about the flight provided at any time during the flight except for when we were preparing to land. Compared to American Airlines (which we flew with on our way to Denver), Frontier has no comparison. There was absolutely no entertainment provided, and there were additional costs and fees at every turn. Not only do they charge for any and all refreshments, they also charge you to have a carry-on bag. The flight was also very very loud. The cabin rattled and roared for the entire hour and a half flight. We will not be flying Frontier again unless some major upgrades are made."

Cons: "It waa cancelled"

Cons: "Rude about luggage and not polite"

Pros: "First time flying with Frontier. No complaints other than having to pay for my carry on luggage. But when I only spent $80 (taxes and fees included) to fly from Dallas to Denver, I'm still happy."

Pros: "Delivery of promised services"
Cons: "Things out of anyone's control ie security"

Pros: "Easy boarding, older model plane with reclining seats and padding, friendly crew members, flight was 45 minutes early upon arrival."
Cons: "Expensive carry on fees."

Pros: "Friendly check-in at Denver airport, smooth process"
Cons: "Nothing really."

Cons: "I bought my ticket online for $41. I went through two long lines to get my boarding pass. At the end of the second line I was refused a pass because it was 25 minutes until flight time. I was told I had to be rebooked on another flight to the tune of $99 plus $30 baggage fee. Since I had no other choice I rebooked for a flight NINE hours later. After all this I was sent to TWO different WRONG gates nearly missing that flight. At least I got an apology for that. The wrong gate fiasco was because Frontier shares gates with Jet Blue and Spirit. I could not hear the gate change announcements because I am hearing impaired. A lovely way to spend a day in Denver!"

Pros: "crew was fantastic"
Cons: "seats do not recline, and very narrow."

Pros: "price is excellent"
Cons: "changed gates 3 times and flight delayed due to maintenance issues"

Cons: "No complementary drinks. Short fold down tables."

Pros: "The price"
Cons: "You get what you pay for, I guess. It's so sad to see a once customer-focused company become only about the numbers. Tiny seats, EVERYTHING is an up charge."

Pros: "Nothing"
Cons: "Everything"

Cons: "Very slow baggage claim. Had to wait about 1/2 hour."

Cons: "The plane didn't leave the terminal for over an hour after boarding!"

Pros: "We got to LA eventually."
Cons: "With the unexplained 4 hour delay I could’ve driven faster, which I’ll do next time."

Pros: "The humor of the crew."
Cons: "N/A"

Pros: "Nothing"
Cons: "Nothing"

Cons: "Website check in held up my process stating a spirit agent would need to help me further. Price was held for when I got to the airport. I was charged at the gate for a personal seat choice to get extended seating that was from my online check-in. I was told I would be assigned a seat at the gate. I was placed in an empty seat near the back, not the seat I paid for. Ticket agent was not helpful at all"

Cons: "Was stuck in LA because Spirit told me it I shouldnt have a problem making my connections. WRONG. They had no other flights out. I had my 2 young kids with me and we were not going to sleep in the airport, so we had to book a hotel. I lose a night of hotel in seattle and my car rental because i was a no show."

Pros: "The price"

Cons: "Will never use this airline again."

Pros: "Did not have any food. Plane left and arrived on time."
Cons: "Everything was great"

Pros: "Space"

Cons: "It was really cold inside"

Cons: "THE COST"

Cons: "Ugh"

Pros: "You get what you pay for. Departed on time and arrived early"
Cons: "The beverages (soda) were overpriced."

Pros: "Entry point pricing."
Cons: "Add on pricing for everything."

Pros: "Price"
Cons: "Small, but still worth the price"

Cons: "Little to no communication from staff. Hidden charges on baggage. Different instructions/information from different staff. Delays, no apologies."

Cons: "My round trip ticket was $150. Great deal except for the added $100 for my check in luggage! Which would have $110 if I would have carried on a bag! Ridiculous! For that price I could have taken another person with me! Next time I should just wear all my clothes I would normally pack and check nothing in! LOL!"

Cons: "I didn't like the baggage policy. I didn't like the check in policy or the fact that they don't support TSA precheck because they hope to sell you on an additional fee that will get you through a prority lane. I didn't like the seats which are hard plastic, close together, and don't recline. I didn't like the mini tray table that wouldn't support my laptop so I couldn't work. I didn't like that Spirit falsely advertises with the tag line "LESS MONEY, MORE GO" when the base fare for my connecting flight on this sub-par airline was more expensive than a direct flight on a better airline-before the other fees were added."

Cons: "I had to connect in Las Vegas from Denver on a delayed flight, the connection as well was delayed. My self and traveling partner grabbed a sandwich returned to departing gate and plane was boarded and taxing away. They left early to make up for delay but we were not warned nor did they attempt to intercom us. We were 100 yards away. We had to take a flight 24 hours later and cost me $400 in hotel and a day's work. Very disappointed"

Pros: "The personnel was personable."
Cons: "Everything, truly everything. Awful plane, awful prices, not good."

Cons: "Didnt understand the charge for luggage. Wasnt able to get a live person that understood my questions. Overpaid on luggage that I didnt have to check in."

Pros: "Nothing"
Cons: "Everything"

Pros: "Cost was cheap, left on time, friendly service"
Cons: "No complimentary drinks. No entertainment available. No WiFi."

Pros: "Bery confortable"
Cons: "N/a"

Pros: "The flight attendant didn't make a fuss when she saw me crying on the plane. I was very upset to be leaving Denver. She just gave me napkins and let me be. Also, the attendant who checked in my luggage at the desk was more than helpful and so patient with me especially since I was a bit frazzled."
Cons: "Nothing! I'd fly again."

Pros: "Delayed"
Cons: "Being delayed"

Cons: "Flight was late. Had to wait for luggage 45 minutes. Had to pay $40 fog luggage."

Pros: "The person sitting next to me"
Cons: "Plane was delayed"

Cons: "You have to pay for everything check a bag $50 each way you want to pick your seat $9 each flight it's such a joke"

Pros: "Friendly staff"

Pros: "Good value. Absolutely no bells and whistles."
Cons: "Perfect for a very short trip. Bring your own everything."

Cons: "Long lines, poor service, lack of communication w/ passengers"

Pros: "Liked first class seats"
Cons: "Didn't like the fact that when I got to lax my bags tock 1 hour to get to us and also my bag never mad it down the carousel I had to go up and get beacuse it stopped your guys customer service in Los Angeles sucks and the do a horrible job she didn't even know what was going on with out bags didn't know where our bags where or when they where arriving last time I fly with spirit airlines"

Pros: "I liked how short the flight was, because I wouldnt have wanted to spend another minute necessary on that cespool."
Cons: "There was a rotted out banana peel in my seat pouch, and gum stuck all over the seats."

Pros: "Comfortable seating. Great customer service."
Cons: "Paying for our luggage! $52 seems pretty steep!"

Cons: "Changed gates with out any kind of announcement"

Cons: "Our two bags never get checked to be sent with the flight, and we have today to pick them up ourselves in San Diego."

Cons: "Flight was delayed so I missed my connecting flight and had to pay for my own accommodations in lay over city until next day because there are so few flights with Spirit."

Pros: "THE FLIGHTS LEFT ON TIME AND ARRIVED ON TIME. MY LUGGAGE ARRIVED SAFELY"
Cons: "I MISUNDERSTOOD ABOUT THE CARRY ON LUGGAGE AND PREPAID $72.00 FOR WHAT YOU CONSIDER A PERSONAL BAG. I CALLED IN BEFORE I BOARDED MY FLIGHT TO DENVER AND SPOKE TO SOMEONE AT SPIRIT WHO REASSURED ME THAT THEY WOULD REIMBURSE ME THE $72.00 WITHIN 7 DAYS. I DID NOT FIND OUT IF THEY WOULD MAIL THE REFUND TO MY HOUSE OR WOULD SEND IT THROUGH PRICELINE WHERE I PURCHASED MY FLIGHT????"

Pros: "great service"
Cons: "1 layover but only 1/2 hr"

Pros: "tome schedule"
Cons: "amount for my luggage......complete rip off"

Pros: "took off and landed on time and smoothly."
Cons: "Cost of checking baggage - obscene!"

Cons: "The Flight was delayed for 7 hours but through out the process there was no clear information when we would be able to fly. So it was hard for us to make a decision on what to do. The airplane we were supposed to ride arrived 6 hours late at 12:00am and they told us first that if we dont board by 12:30am the flight will be canceled and rushed us to the changed gate. Then told us because of inspection that the flight will leave maybe in an hour. We ended up boarding at 1:30 and the flight attendant had no regard of our situation. She made loud and unnecessary PA annoucements such as "now we will dim the lights for your comfort so you can rest well" after the plane has been in the air for 40 minutes. Just overall a terrible experience. I understand now why the price is so cheap."

Pros: "Great service"

Cons: "My flight was so delayed I missed my dinner, my ride had to leave so I had to pay for that, and I couldnt check into my airbnb. This long delay cost me so much money and really affected my trip and reason for going to LA."

Cons: "If you just want to fly and not bring a carry on or care where tou sit then it can be worth it. But paying for baggage is a little too much considering it almost always costs more than the flight itself. I would rather pay more for another airline off the bat then get stuck paying surprise fees later"

Cons: "I was almost charged for my trolley bag, just because you decided it does not fit (by a centimeter) in your stupid measurement. I had to insert it to my luggage (in 2 shots - the second time it was OVERLOAD???!!!)... Are you serious? Very disappointed... I will try not to fly spirit anymore... Erez Nassimi erezn@hotmail.com"

Cons: "Did not like the fact that i was on time to my flight but my flight didnt not leave for an hour after it was schedualed due to a "computer" problem. It didnt seem like much was wrong since all the mechanics were just sitting around talking to the flight attendants. Also the plane kept making this unusual grinding sound before we even took off as well as while we werr in the air. The flight attendants were very rude to alot of people, careless with the credit card machine dropped it very roughly on the ground and laughing about it. I am pretty sure the older one of the three was drunk because she reaked of alcohol , I didnt not catch her name but she was the ruddest of them even to an elderly man and a small child. Then Liz was also very rude to customers as well as having an attitude that was as if she didnt carr about her job. The man Gustavo was not to bad he just spoke over the intercom as if he was new. My mother who was traveling with me asked for a seat belt extender twice and the third time was finaly given one and laughed at by the staff and the during the flight she discoverd a roach in the pouch in front of her. Also back to a referance to the bad staff a woman sat next to us asked for a pain killer or some sort and was told " i cant give it to you before we take off, and if i could we dont have anything other than our own"-liz then twords the end the poor girl was sweating drasticaly and holding her stomach and the older attendent whose name i did not get came up and said " WHATS WRONG WITH YOU?" and laughed. Over all i was NOT haooy woth this flight i do understand the fact that i GET WHAT I PAY FOR BUT THAT WAS JUST RIDICULOUS."

Pros: "Organised"
Cons: "Paiing for lugge is ridicules"

Pros: "Nothing"
Cons: "Everything about my interaction with this company."
