Pros: "The crew and entertainment options are great. Relatively comfortable seats by today's standards."
Cons: "Literally any of our flights could have been on time. None were."

Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"

Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."

Cons: "1.5 hour delay...no reason given!"

Cons: "Flight was delayed and completely packed so our family could not get seats together"

Pros: "Love the fact that the head rests move to support your head better."

Pros: "The seat was great, I wish all seats on the plane were that comfortable"
Cons: "Nothing, everyone was great"

Pros: "The male crew member was excellent. He was responsive and speedy with trying to find a solution. He gave me a few flyer miles for my trouble and was empathetic, which is rare."
Cons: "The tv/monitor didn’t work so there wasn’t any entertainment for the majority of the flight."

Cons: "No meal option and my video screen volume did not work"

Pros: "The crew was great and super nice!"
Cons: "Screens with games, more leg room, and not having kids behind us messing with tray tables the whole flight."

Pros: "Boarding was easy."
Cons: "I am 6' 1" tall and weigh 220, so not out of the ordinary and I felt like I was stuffed into a sardine can."

Pros: "Not comfortable a little but scary on the flight to Detroit. Way better coming back to Denver"

Pros: "great crew!"
Cons: "luggage. what a nightmare. I waited 30min for my luggage (after a delayed flight) only to be told by a fellow PASSENGER that some of our luggage was directed to a FRONTIER CAROUSEL. I then had to wait by that carousel till I found it. so much for "bags in 20min guaranteed""

Pros: "Inflight experience was fine. TVs didn’t work but Flight attendants are friendly on Delta, cramped seating - but not unlike other airlines."
Cons: "Regular fare seat assignment not available prior to gate . Airport concourse F - poor - limited services. Customer Service seemed uninterested and unable to provide service both on phone and at gate. I’m a frequent United flyer & today’s Delta service experience made me more loyal to UA."

Pros: "Early and middle seat was open!"
Cons: "Coffee tasted like fish. :("

Pros: "The crew on the airplane was great. We had 2.5 hours turbulences but the crew started to give out drinks as soon they got the ok from the pilot"
Cons: "We went in LGA to the Baggage drop off and the employee there was super rude. On the flight to New York with Delta we had to check our carry ons at the gate because it wasn't enough room for bags in the airplane.so we asked when we checked our one suitcase if we can/should check our carry ons to avoid having to do it at the gate. The delta employee told me sure no problem. He checks in my one suitcase I purchased gives me the tracking paper and says ok have a good flight. I asked him so what is with our carry ons and he told us that that would cost 25$ and we can't check those in at the drop off?!?We ended up taking the carry ons with to the gate and then off course there wasn't enough room on the airplane that we had to check it in. And surprise it was free?? We had never issues with Lufthansa, icelandair etc. with checking our bags at drop off to not needing to carry it around and than still end up to check it at the airplane. Every airline has been more than happy that we volunteer to check our bags that they don't have the trouble at the gate."

Pros: "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: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"

Pros: "JFK to Denver the flight Attendants were once again great. Lots of entertainment choices again. The usual rough air coming into DIA."
Cons: "From JFK to Denver the seats were to close for leg room by an inch or two. The temperature was hot most of the flight."

Pros: "The Delta service desk was great! We wanted to get an earlier flight home and the Delta Rep got us on standby quickly and with a smile."
Cons: "Some chaos getting on the flight. The area they have set up for the different sections to wait before getting called weren't marked very well so everyone was bunched up and confused. Once they started calling the sections it was fine. Not sure why they even had the marked areas."

Pros: "My upgrade and breakfast were fabulous!"

Pros: "Love the built in tv’s with free entertainment."
Cons: "The plane got delayed on the runway and the shut the engines off so the plane got super hot, but even after we got up in the air it never cooled down. Normally I’m freezing on flights, but I just sat sweating this whole flight. It was terrible."

Pros: "The seats had plenty of leg room and the crew was was very kind."
Cons: "My seat was uncomfortable and I was seated in the only row of the aircraft without entertainment for a four hour flight. Then on top of that the passenger next to me removed his shoes and you could smell his feet from a mile away but the flight attendants never requested for him to replace his shoes."

Pros: "Staff very courteous and professional"
Cons: "None"

Pros: "I usually have had great experiences with Delta. The meal selection was limited. By the time they made it up to my seat they had run out of what we wanted. Also, the entertainment system at my seat and my husbands wasn’t working well. One of the bathrooms had a cabinets Tvst oliiiooooiiooooioiooiiiooiio"

Pros: "When deplaning in Denver, I was impressed that the captain was the staff who got behind my wheelchair and offered to push me up the walkway :)... New aircraft, kind staff, shorty flight!"
Cons: "Nothing disappointed, butt i didn't have any good besides pretzels."

Pros: "Not much to like here. The new crew was pleasant"
Cons: "Old crew was surly. Plane had much problems and finally replaced. Left 5 hrs late. Delta claims it doesn't have to compensate for a late flight - just a cancelled one so guess which this was The baggage fees are obscene and the gouging of the customer is immoral. No wonder people hate the airlines."

Cons: "Excellent service excellent pilot"

Pros: "The airline did not disappoint and the customer service were very professional"
Cons: "Make sure the new signs are posted in all airports for boarding. That will help control people at the entrance"

Pros: "Overall, the flight was very smooth and I thought the crew did a great job."
Cons: "I know this is a federal regulation, but I have to mention it as it is part of the boarding process. For the life of me, I can't understand why it is necessary to go through security again after re-entering the country. Understandable that I have to go through customs, but going through security again is ridiculous."

Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"

Pros: "Free in flight entertainment"
Cons: "One of my bags went to Santa Fe"

Pros: "Entertainment"
Cons: "This is my third flight this year with Delta and every time we wait for the "crew" to get off from another flight. And as soon as they get there we can board. It's getting very annoying. Fix it."

Pros: "I love the new snack choices! Way to go Delta for offering Kind bars now!! This is awesome."
Cons: "Tiny old plane, props blocked my window view, no entertainment system."

Pros: "The staff of the flight were very friendly and attentive. They were great!"

Pros: "Smooth"
Cons: "Delayed because the airline misschdduled the pilots!! We had to wait for pilots to come to the plane... while one the plane"

Cons: "I'm tired of Delta making it IMPOSSIBLE to experience benefits of my loyalty. I flew literally AROUND the world in the past 6 months and it STILL doesn't qualify me for anything more than Silver elite? Seriously? When you use a voucher because of their error to lower your ticket price, but still pay cash for it, why does that then automatically exclude you from upgrades? Poor customer loyalty, in fact, non-existent these days."

Pros: "Early arrival. And service"
Cons: "I was assigned very last seat and there is no reclining option."

Cons: "long wait and delayed flight"

Pros: "One male attendant from the first class cabin - super sweet and attentive to our needs even tho we're not seating in the premium cabin"
Cons: "Junior attendants in economy comfort seat - so lazy and whiny!"

Pros: "From the Ground crew to the Flight crew, you can feel the genuine care and thoughtfulness of everyone! They even remember you, if you fly often enough, and let you know how much they appreciate your business."

Pros: "Very professional and caring."

Pros: "plane had individual movies for free with each seat!"

Cons: "Flight was repeatedly delayed. Ended up being over 3 hours late to depart due to weather. Another delay due to mechanical problems."

Cons: "I've only experienced delayed flights with Delta ... and this was no exception. It wasn't weather-related, nor a late flight delivering a plane - just no ground crew to service the plane between flights."

Pros: "Good service"
Cons: "Good and not much leg room"

Cons: "Very turbulent flight"

Pros: "leaving on time"
Cons: "Crew's facial expression were upsetting to see since they looked unhappy. Should I be worried about my flight?"

Cons: "Flight delayed due to weather. Rebooking was a zoo, had to pay for hotel room and worst of all waited over an hour at baggage claim to get our bags back. It's taking us 2 days to get from Albuquerque to Austin."

Pros: "Security was quick and efficient. Boarding was extremely organized. The airline attendants were attentive. The pilot on United informed us when the possibility of hitting turbulence occurred so we could adjust accordingly. Overall, great travel experience."

Cons: "My bag was lost but my husband's, checked at the same time, made it."

Pros: "Nothing"
Cons: "Refused to delay connecting flight in Denver even though severL of where already on ground in delayed flight coming into Denver. Albuquerque flght was still at gate when I got there, having run through airport along with several others. We were refused admission to plane despite delay being United's fault. Unacceptable! I will avoid flying United in the future whenever possible"

Pros: "I didn't fly.I bought the ticket for my son. He had no complaints. You should ask in your questionnaire if the booked flight was for self or someone else."

Pros: "Got there on time."
Cons: "Private screening does not work well. Very little kneeroom. No room in seat back pockets to put anything."

Pros: "Flight was on time; both ground and flight crews were pleasant and efficient."
Cons: "They were out of ginger ale, my beverage of choice :-)"

Cons: "Terrible experience ever!!!!! Didn't get economy plus that I paid for, seats didn't recline and luggage got damaged and was not replaces or compensated for."

Pros: "Nothing because they didn't allow us to board the flight because there was 20mins left til the plane departed. Also the tickets were bought with 24hrs and they didn't refund or give us a flight credit."
Cons: "They didn't allow us tothe tickets were bought with 24hrs and they didn't refund or give us a flight credit."

Pros: "Flying in America gave me no problems. Things only got terrible after we left Denver."

Pros: "The service was food"
Cons: "Lack of leg room!!! After my bicycle box was inspected they failed to secure my bike the way I had it in the box. Bike was flipping around in box. Bent rear brake calipers. Bent brake hoods. Rear skewers were uncoupled. No way to treat a $10,000 bike! Very upset!"

Pros: "Had a stroller, two bags, and a car seat and the check in staff helped us tag everything and loaded it for us. It was nice to see the Billings staff go above and beyond in my families time of need."

Pros: "They sent me a text message telling me it was canceled"
Cons: "Unfortunately, despite the text message saying the flight was canceled, the ANA ground staff in Taipei that we talked to assured us it was not canceled. But it was. And so ensued 24 uncomfortable hours of pain. Thanks, United."

Cons: "A la ahora de irnos hubo muchos contratiempo por el tiempo pero por el vuelo después que nos fuimos fue excelente"

Cons: "Bad snacks. Need biscotti"

Pros: "It was a quiet and smooth ride."

Cons: "Unreliable wifi."

Pros: "The flight was snooze and the flight staff were friendly!"
Cons: "N/A"

Pros: "Crew was nice and friendly."

Pros: "The flight attendant finally took care of it after I complained a couple of times."
Cons: "That you changed our seats, and, that there was no room in any of the overhead bins. So, the flight attendant told me that I needed to fight my way through the people coming toward me back up the aisle and check every overhead bin all the way back up to see if there was room for my one suitcase. Others had brought more than one bag up there. Finally they checked my one carry on bag. The ride was also really bumpy, worst that we've ever experienced. But that was due to weather conditions."

Pros: "Getting off the plane"
Cons: "Bathrooms weren't working, huge lines in aisle, lackluster service. Overhead bins were full by Group 3. late takeoff."

Pros: "I wish all airlines were like Lufthansa. Lufthansa still cares about the passengers, while others only care about profit."

Cons: "One strange thing happened on my United airlines flight. The crew announced before we boarded that there wasn't enough overhead space for rolling bags and encouraged us to check them in. Upon boarding they announced that all overhead space in the back was full. I sat in the back and noticed that the crew closed the overhead compartments even though they were mostly empty. Another passenger opened an empty one and the crew came over and closed it right away, though many people were still boarding. What's going on?"

Pros: "United seems to be recycling which is a good thing."
Cons: "The obnoxious child sitting behind me. He kicked the seat and pulled on the tray."

Pros: "San Antonio flight to Denver delayed too long where could not make connection in Denver to Toronto. Had to make other flight arrangements."

Pros: "Under booked flight was a plus!"

Pros: "Arrived early and flight crew was super nice!"

Pros: "That the flight was on time. disenchanted flight attendants. Makes you want to not need her assistance."
Cons: "Disenchanted flight attendants. For whatever reason, it is obvious that there is unhappiness. Not flat affect, just the look of disinterest, a look that tells you I don't care. In a customer based business it is so disheartening that the very person you may have to depend on to survive is not vested in the clientele that keeps her company in business, thereby insuring future paychecks. I'd like to communicate here that it wasn't all the attendants on either flight, but enough that it was obvious to anyone who paid even casual attention. I was flying home to California, so there were two additional flights a few days before the flights home. I never had any of the same flight attendants on any of the flight. As far as my observation of the attendants, as stated above, I think that speaks volumes. I will cite an example that happened on my trip from Iowa to Denver. I need wheelchair assistance, I walk with a cane, but not able to walk any distance. I pack a light carry-on, bring my purse, jacket and cane. I was being wheeled up the passageway in a regular wheelchair, and the man pushing me stated to the on-coming crew he "would be right back to get my suitcase, couldn't take both at the same time", and added " unless one of you could roll it up?". After an embarrassing pause, a female flight attendant said "Let the flight attendant do it. Add this to the list of responsibilities that aren't really my job." I actually twisted around to look at this person, I was so stunned to hear that! She grabbed my rolling carry-on handle and the look spoke columns. I was embarrased. Thank you. Debra K. Forsythe"

Cons: "It’s was delayed 3 hours in buffalo ."

Pros: "Couldn't get buttons to work on previous page. flight was fine"

Pros: "Nothing. Absolutely nothing. I mean I got where I was going and didn’t die, but that’s about the extent of the positive things I have to say."
Cons: "Very uncomfortable seats, no beverage service. Up charge for literally everything, carry on’s were charged, as much as checking bags. I’ll be avoiding frontier like the plague in the future."

Cons: "Plane was too hot"

Pros: "Cheap price"
Cons: "4 hour delay and terribly uncomfortable plane."

Pros: "Crew was polite"
Cons: "Staff tried to make me pay for two carry-on's for one bag and one purse--totaling to $90. You have to pay for soft drinks. Generally bad experience and a rip off."

Pros: "The prices were reasonable."
Cons: "Check in personnel didn't arrive until and hour before the flight was scheduled to take off which left myself and every other passenger waiting in line for over an hour. The new seats look very nice, but are just hard plastic covered in faux leather leaving passengers with an uncomfortable experience. They did not recline, which wouldn't have been a problem if the tray tables weren't the size of an iPad mini. The seats were so close together you couldn't even rest forward onto the tiny tray tables without hitting your head on the persons seat in front of you. I am by no means a large person at only 5' 3" so I can only imagine how awful it was for tall people! For a three hour plane ride it would be better to go with any other company."

Cons: "They changed gates and there were no signs or announcements. We would have missed our flight if I hadn't searched out an airline employee and asked."

Pros: "A very smooth flight and landing"

Pros: "Everything except one issue."
Cons: "The handle on luggage was broken by baggage handlers at TYS airport when arrived in Knoxville, TN"

Pros: "Equipment was relatively new so no issues there. Orderly boarding and clean cabin. Flight crew did a superb job! Cabin crew were polite and accommodating enough. Gate agents were efficient and friendly, Can't comment on the quality/quantity of food or beverage as I opted not to give them any more money, Make sure to download the Frontier app on your device BEFORE boarding or you will have NO entertainment available! The entertainment is complimentary but there's a charge for internet."
Cons: "I had discovered the carry-on bag charges AFTER purchasing the ticket online which is a bit underhanded. My 'bargain' ticket was now the same price as every other airline plus the 'privilege' of food and beverage purchase whereas all the vanguard carriers still offer free carry-on, snacks and soft drinks. BTW unless you're drunk or completely exhausted, don't plan on getting much sleep: the seats were made with some of the thinnest padding I've experienced and you might get 3-4 inches of recline, IF you can locate the lever! IMPORTANT!! If you don't order THE WORKS pkg ($55) when you INITIALLY pay for your ticket, which includes refund waiver along with check-in, carry-on and seat choice, you're stuck with THE PERKS ($45) which has all the above EXCEPT the refund waiver. The refund fee is $99! You can do everything a la carte, but will cost more beyond 1 bag. BTW, do it all online or you'll pay more at the airport. All in all, absolutely fine for the price if you have a personal sized item (i.e. up to a small backpack) but a standard size carry-on or check-in will definitely put a wrinkle in your flight budget!"

Cons: "Rude lazy attendants. No effort to offer even water to me on a two hour flight. All they wanted us to do was clean up trash to make their job easier. Nickel and dimed and this kind of service?????? Also didn't need a repeated 15 minute sales pitch for a credit card!"

Pros: "Personnel were great"
Cons: "Luggage took over an hour"

Cons: "50 minutes late with no warning"

Pros: "Steamboat Springs, CO There were many CUBS fans on this flight! Good to leave rainy Chicago & arrive in dry Denver! Even though the plane was late, I was still able to catch my Alpine Taxi to Steamboat!"
Cons: "There should be a way to know when the bathroom is available!"

Cons: "I contacted Frontier about a week before my flight to let them know my friend I was flying to visit had to make an emergency trip to see her father who was dying of liver failure. On the first attempt I was notified that only immediate family members were would be an excuse but that I could try to request through a different faucet of emergency circumstances. I put through another request and was never contacted. I did not fly to Salt Lake but I was still charged even though they could very well have sold my seat to another person and made double the money for the seat. I am very disappointed with the service I received from Frontier."

Pros: "Nothing"
Cons: "Everything. Frontier is the worst airline I've ever traveled on. Even worse than United somehow!"

Cons: "40 minutes and still no bags"

Cons: "Crew was a bit rude. I went to put my bags in an overhead compartment and was the flight attendant snapped at me and said I couldn't use that one. Had he explained it was just for the front row instead of being rude, I would not have taken issue with it."

Pros: "Nothing"
Cons: "Delayed on the way there and delayed on the way home. Hen we sat on the runway for another 45 minutes waiting for a gate to open. Never again will I travel with Frontier!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"

Pros: "the ticket was the cheapest."
Cons: "-$30 (at least) for ONE carry-on. Some people had a personal item only. I then noticed that at boarding, the attendent didn't seem to be checking people's ticket and wether or not they had a carry-on. ಠ_ಠ -When you check-in online, they make it look like you have to pay for your actual seat. ($13-30) I was shocked. However, I realized later that if you scroll down all the way, there's a "skip" option. Turns out, you're paying to reserve a seat, versus them automatically picking one for you later. ಠ_ಠ I was a little upset when I realized this. -my tray table was the size of an ipad mini -they've shaved a few inches off of everything, so it was a tight fit. -everything but water costs money. Soda is 1.99 for an 8 oz can. -no tv, no headphone jack in the arm rest."

Cons: "The same 2 screaming babies entire flights. Attendants allowed with no assistance."

Pros: "flight arrived on time"
Cons: "Flight arrived on time sat on tarmac for an hour waiting for a gate. Checked luggage took another hour. three hours in destination airport before we could get to our car. this airline sucks the big weenie!!"

Pros: "Good Fly, nice atention and good landing"
Cons: "the seats do not recline"

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

Cons: "The portland-denver flights are NEVER on time. I will never be booking with frontier again."

Cons: "There were several delays."

Cons: "I did not book this particular flight for these dates."

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: "Wellllllll it didn't crash I guess that's about it"
Cons: "An hr delay, only one working bathroom, rude staff, late 45min wait for checked bag. Overall got to my destination in Denver about 2 hrs late."

Pros: "nothing"
Cons: "They honey dick you with the cheap plane tickets then screw you over at the the counter when they charge an unnecessary amount for carry on baggage. I WILL NEVER FLY FRONTIER AGAIN. Not to mention the meal trays can barely hold a lunch-able... Go home frontier airlines.. your drunk."

Pros: "Seats were wider than most airlines and there seemed to be a couple of inches more legroom, but the seats were thin and not very comfortable."
Cons: "Unexpected fee for carry-on baggage. Who ever heard of being charged for a CARRYON? The airline provides no service with carry-on luggage- all the work is done by the customer."

Cons: "Another subpar experience with frontier and my last"

Pros: "It left on time"
Cons: "The chairs are like torture devices. They replaced their humane, padded chairs with these ultra slim hard plastic ones that don't recline so you're stuck sitting at a 90 degree angle with basically no padding so they can fit more seats on the plane with tiny tray tables. I'd like to see the CEO spend a couple of hours in one these. I'll never fly Frontier again because they've completely lost touch with the concept of treating customers with dignity."

Pros: "When it was over"
Cons: "Even though the ticket is cheap, you have to pay outrageous prices for literally everything else. You have to pay to reserve a seat (any seat) otherwise they can separate your family on the plane. You have to pay for drinks (even water) no matter how long your flight. You don't get a free carry on bag and if you don't book the bag before you get to the airport it can cost you north of 45$ to check it. The accommodations themselves were not great. The chairs have no cushioning, don't recline, are so close together that I couldn't cross my legs, and the tray table is 4 inches wide and couldn't even hold my laptop. The flight attendants on both flights were extremely rude and ran into me with the drink cart twice. One of the flight attendants when asked if the AC would be turned on since the flight was pretty warm asked if the woman wasn't just having hot flashes. She was upset tingly abrasive. The flight was delayed on the Tarmac for over an hour because the team couldn't load the baggage on the flight. The flight team didn't give us any explanation of the delay beyond that, they didn't update is on the expected time delay and they never apologized for the delay. When we did finally get going the flight crew was very rude with asking people to sit back down. Worst of all was that after all of that they lost my luggage. Despite a 2 hour layover and 1 hour delay at the gate specifically because they weren't done loading the luggage Frontier couldn't manage to get my luggage from gate 42 to gate 44... The whole experience was awful. I would never fly with them again no matter how cheap the ticket."

Cons: "This was the oldest plane I had been on in quite a while. The tray tables where half the size of the regular ones and metal. There was hardly any legroom. There was absolutely no entertainment options. No Wi-Fi on the plane. And you had to pay for any snacks and drinks. Although I did get a great amount for the cost, I would have paid a little extra to fly a different airline in order to have Wi-Fi and entertainment options."

Cons: "Flight was delayed 3 hours, then we boarded the plane at 1:46AM. Only to have the flight cancelled. After 45min on the plane we had to get off and wait until 3:45AM to find out what the next step was (rescheduled for 11:30AM). Overall the communication and transparency around this ordeal was handled terribly. Staff had no plan to deal with situation, provided helpline numbers were useless, email/text communication of the rescheduling was nonexistent All of this is not even getting into the cheap service and setup of the flight itself. Will not be flying frontier again"

Pros: "N/A for food or entertainment"
Cons: "Spend the extra money & book with another airline! Staff was rude & contradictory on policies. Was charge for checkin baggage for a skateboard!?! Ridiculous. There was no sleeping in these uncomfortable seats. Flight late. And was an hour wait for luggage."

Pros: "Boarding was easy and efficient"
Cons: "Seats aren't the most comfortable. Tiny tray tables and the seats don't recline"

Cons: "My flight got canceled so I had to buy a new one."

Cons: "The online price was competitive, but it was bait and switch, because I had to pay an additional $90 for a single overhead bag, round trip."

Cons: "Paying up to $60 for a carry on. Waiting on the runway for 30 minutes with no communication from the pilot when we landed in Denver."

Cons: "I hjave never flown on an airline thaty charges you for drinks and snacks"

Pros: "The plane didn't crash."
Cons: "Many years ago, I was an Early Rewards member who flew Frontier any time I could. No longer. The ticket price no longer resembles what you will pay. Now they charge $15-35 to get a seat,another $30-$35 to check or carry on each piece, and sit in uncomfortable seats that do not recline. These extra charges cause long delay at the check in counter even if I already checked in and only needed to check a bag because everyone else had to pay. Now I'll only fly Frontier if there is no alternative."

Cons: "Extra charges like bags, seats, snacks. Slow boarding and deplaning. Very rough flight"

Cons: "Expensive bag fees and $2 for a soda"

Pros: "The 40 minutes the flight was late the crew made up in the air"
Cons: "Took 45 minutes for baggage to appear"

Pros: "I got where I was going to."
Cons: "One zone isn't even through the door and the next zone is called and all we do is stand in the very hot jetway for nearly 15 minutes. Being charged to pick our seat and for our luggage is ridiculous. It should be included in the price, if you have to raise the price then at least people would know better the true cost of their travel. Being charged for a drink! Having $1.99 put on a credit card! Wrong."

Pros: "The crew was pleasant and helpful for those with screwed up flights"
Cons: "Flight was delayed the excuse given was lame so it was caused by the airline. I have not flow frontier in some time the delay coupled with the worlds most uncomfortable seat. Pretty much ensures I will note fly Frontier again for some time"
