Pros: "The flight didn’t have entertainment which is fine. I can entertainment self."
Cons: "Carry on bags cost extra."

Pros: "Nice stewardesses - very polite and helpful"
Cons: "When I checked in online the day before, I was only given seats that I had to pay an additional charge! I had already paid for my tickets when I booked the flight. This is ridiculous to check in and be expected to pay an additional charge just to get a seat! No snacks unless you pay for them - also ridiculous."

Pros: "Direct flight"
Cons: "Delays before we boarded, plus delays after we boarded. Communication about what caused the delay seemed like an afterthought."

Pros: "The employees were so attentive & caring. Very accommodating. Was pleasantly surprised."

Pros: "The San Francisco based crew and customer service was very welcoming, friendly and accommodating."
Cons: "On the return flight (out of their hub airport!), their online system failed so it didn't capture that we had prepaid both our checked bags nor our seat selection. When we arrived at the ticketing counter they were essentially accusational about the issue. We showed the confirmation page on our cell phone and even logged into our mobile banking app to show them and still had to argue about paying again. On top of that, they acknowledged the system was having issues and would do absolutely nothing to help us get seats together (my husband and I), let alone anywhere near what we had selected during the online check-in process (we paid extra for an aisle and middle towards the front of the plane, and they gave us two middle seats in the back of the cabin). There were four empty seats in first class, and they wouldn't even bump up a frequent flyer to give us seats together in coach. Not once did anyone apologize, ask how they could help, or just try to be helpful. Both "managers" were clearly poorly trained in handling these situations and defensive and dismissive (walking away while we were speaking). They didn't even offer a free meal voucher. Nothing was done to help rectify the situation. It was honestly shocking how terrible of an experience it was - no indication that they felt we were a paying customer. There were so many little things they could have done even without changing our seats that would have made the situation better. I will never fly this airline again, out of principle, and will absolutely share my experience with everyone I know. If someone from Sun Country reads this, the managers' names are Oniekey Brown and Jolynn Carpenter. I would suggest your management chain have a conversation with both of them and highly suggest training."

Pros: "Everyone was kind and helpful."

Pros: "This plane was what it was, the crew was nice and didn't have turbulence, they offered food for purchase and entertainment. Only 70% full"
Cons: "Seats aren't great for a 6'3" guy, it was hard to put my head back because of the seat shape, the plane was old, it even had ash trays in the arm rests. leg room in a normal isle was cramped."

Pros: "On time, friendly efficient service from the crew Luggage delivered with very little wait time. This was our first time with Sun Country and won't be the last"
Cons: "Nothing negative to report"

Pros: "The boarding was efficient and the plane left on time."
Cons: "It would be nice to get a snack along with the beverage, like peanuts or crackers. There is minimal leg room."

Pros: "All went well boarding. The flight team was friendly."
Cons: "I couldn't print my boarding pass online."

Pros: "Not turbulence, but over correction. Worried we had a junior pilot. Pilot should have come on speaker after take off incident, many afraid passengers."
Cons: "Older plane, not super friendly flight attendants"

Pros: "Comfortable, friendly staff, early arrival"
Cons: "Should have free wifi since no on flight entertainment"

Pros: "Friendly service"

Pros: "The flight was on time."

Pros: "Good service; free soda, stowed our carry-on rollers. Best of all: no hidden fees and extras. Honest pricing good flight. A throwback to better times."
Cons: "As always, exiting plane took forever."

Pros: "Flight attendants friendly, seats comfortable."
Cons: "I don't like that they only offer one hot food - a hamburger. A wrap and or sandwich offering (healthier choice) would be better. Other airlines offer more."

Pros: "The crew was friendly and attentive, there were extra seats on the plane which gave us room to stretch out. Easy experience all around."
Cons: "Apparently (from the conversation behind me), the cheese/cracker platter ran out on the flight, which I had on a previous flight. Its awesome, but if this is worth writing about, then I cant really complain."

Pros: "It was a good flight. Cleanly and comfortable!"
Cons: "No snacks :("

Pros: "Everything was great. no complaints!"

Pros: "All the other attendants."
Cons: "The male attendant. I got sick in flight, sitting in row 8 I went to the front of the plane to use the restroom and he wanted to make me go to the back of the flight. Had I not challenged him when I asked if there was a restroom up front his response was "there is one in the back" I would of thrown up all over on the way to the back. Only when I asked him again and then told him I was sick did he then not argue. Stupid."

Pros: "Check-in was easy and quick. I had great seats (plenty of leg room), flight left on time and landed a bit early which was great."

Cons: "Seat broken, plane late to leave"

Pros: "The staff was kind and accommodating."
Cons: "My seat's headrest was broken and kept rocking forward into my head the entire flight. My seat also did not recline as far as my seat mate's. For first class, this was the least comfortable flight and almost would have taken a coach class just for more comfort. Disappointed!"

Pros: "U S money is legal tender for all debts public and private how come I have to use a credit card when I wnat to pay with US currency doens't seem legal"

Pros: "Wonderful service and the staff was great!"

Pros: "On time"
Cons: "Seats are so close"

Pros: "Gave me good food."

Pros: "Good service and friendly attendants"
Cons: "Both legs of round trip were delayed by 2 hours, and no mobile tickets."

Pros: "Decent price, polite administrative staff in home office"
Cons: "Website - wouldn't allow me to check in, difficulty with mobile site, frustrating repeated issues with seating choices and online check in. Seat assignment - only pre- releasing and then having airline assign certain number of seats is a ridiculous system that results in people being uncomfortable and lacking any ability to exert preferences for certain seating conditions. This is like a process for the 1960s airline, especially combined with the dysfunctional website."

Pros: "At first it seemed cheaper but ..."
Cons: "You won't actually get to your destination. When you choose to fly Sun Country you'll think you saved $50 by not flying delta or American or whoever. When you get to airport prepare to fork over that extra cash because more than likely you'll have to switch airlines. switch ? Why ? Inevitably flights get delayed a little bit and when you get delayed and have a connection to make you'll be royally screwed. The next connecting flight won't be for another 12hours because this airline is the butthole of airlines and always flies like four planes total."

Pros: "Flight delayed for three hours. Wasted my time at the airport for three hours. Didn't receive any notification ahead until I arrived the airport. It was a disappointed experience."

Cons: "The flight from SFO to MSP was delayed due to weather. The ticket agent told me that I would miss the connection to Miami, but that they would put me on another flight that day. When I arrived at MSP, I discovered that I was the only passenger to MIA who had not been re-routed and that the next flight on Sun Country to Miami was four days later. The gate agent at MSP sat me aside while all other passengers who missed connections to other destinations were re-ticketed. After that process, the gate agent made several calls and eventually, refunded my fare on Sun Country. At that point, the only other direct flight from MSP on any airline (and the only other flight that would arrive at MIA at a reasonable hour) was leaving in approximately one hour. I was able to purchase the last seat on that Delta flight for about double the amount of my Sun Country ticket. I then had to go find my bag that was checked to MIA, change terminals, purchase the ticket, negotiate my way through security and run to the gate to barely make the flight. This was my first flight on Sun Country and probably my last. The incompetence of the SFO ticket agent caused a significant disruption to my travel experience and resulted in a significant financial penalty for me because of the ticket price differential between my original Sun Country fare and the last minute Delta purchase. I have been flying for many years and this was, by far, my worst flight experience ever."

Cons: "Crew member opened champagne bottle as passengers were getting on the flight and it spilled on the person in front of me and on myself and I had to ask for napkins from him instead of him apologizing and giving them to me himself. No free food, not even chips or anything. No TVs. I was on a 5 hour flight with no in-flight entertainment."

Pros: "Delayed for an hour And no food ( it's ok but I could give "doesn't app" so I gave one star)"

Pros: "Although the flight was delayed, everything went very smoothly!"

Pros: "Connecting flights held to accommodate late arrival."
Cons: "Flight attendant was abrupt with passengers."

Pros: "Nice flight attendants Sun Country uses International Terminal at SFO. Half the line than domestic."
Cons: "Old Plane. No WiFi. Cramped seats. Chair could not recline down."

Pros: "On time, smooth flight, excellent landing, clean"
Cons: "Good customer service is what keeps your business better than others. Yet I felt a few of the flight attendants were abrasive. I'd want to know this if it were my company."

Pros: "missed my flight and got another one at the same day with no extra fees. i really appreciate this."

Pros: "Boarding experience was pretty smooth. I liked that because it was a 4 hour flight they served us drinks twice. The crew was generally very nice and pleasant. I didn't purchase any food or rent the entertainment center."
Cons: "It was too cold at first (and I saw many others fiddling with the AC vent and putting hats and scarves on), but after I told them about it they turned down the AC to a comfortable temperature."

Pros: "Checkin was smooth and e"

Pros: "I had never heard of Sun Country before flying San Francisco to Minneapolis. I decided to look up the airline on Yelp to see what kind of experience to expect, and found that I may have to deal with delays and rude customer service. I was glad that neither of those turned out to be true. Flight boarded and left right on time, despite being toward the end of the day, and everyone was perfectly courteous."
Cons: "I'm sad for the days when you'd get free food on flights. There are no complimentary snacks on this airline, but then again most have done away with them. So yeah, pretty standard experience."

Cons: "Counter close 45 minutes before the flight . Need to stay 24 hours in the airport to go to the next flight."

Pros: "Sun Country's service and kindness is the best. They're a small airline from St. Paul and that why they're so great. Their whole crew is so nice and willing to help."

Pros: "crew was friendly"
Cons: "worst food options i have ever seen on an airline"

Cons: "."

Pros: "Flight departed and arrived early! Flight was not crowded and seats were roomy. Flight attendants were very friendly and courteous."
Cons: "Boarding process was a bit slow because tickets had to be paper, and tickets were manually torn by the attendant at the gate. Fortunately there were very few people on the flight and we left early. SunCountry's website needs a revamp and facelift - it takes a long time to Check-In or re-print your boarding pass."

Pros: "Nice flight attendants."

Pros: "SFO ticket counter agent was A+"

Pros: "The crew was outstanding and the flight on time."
Cons: "One of the bathrooms was not working properly so everyone had to do with two bathrooms."

Pros: "Fast flight. Made it 12 min earlier to the gate."

Cons: "THERE was NO flight! WTF were you sending me reminders for!!!!! There was complete disruption here, preparing for a surprise flight that did NOT exist!"

Pros: "Free drinks and a snack."
Cons: "United entertainment app doesn't work on all devices."

Pros: "The price was decent. The plane was delayed by about 20 minutes, and they worked hard to get us on the flight quickly so we could make our connector flights."
Cons: "For a 5 1/2 hour flight, the only snack we got was one cookie. For the 4 1/2 hour flight, the only snack we got was a very small bag of pretzels. There is no TV. They give you free United wifi that you can use if you have a device to watch movies/TV on, but they don't have any outlets to charge the device, so it's kind of pointless. You have to download their app before the flight starts. I was having issues with the app on the previous flight, so I tried to get help with it before we took off. Our flight attendant acknowledged she heard my question and then just walked off and didn't help me."

Pros: "Least expensive and quickest trip"
Cons: "Not always available on return trip"

Cons: "Seperated me from my partner after we originally had assigned seats. Middle seats non reclining - horrible"

Pros: "Thought it was cool with the screens in the seat even though I didn't use them"
Cons: "Seats were cramped and the power outlet was to hard to reach since I couldn't see it. I ended up just using my battery pack."

Pros: "Nothing delay"
Cons: "Mahor delay and tarmac issue refund immideate"

Pros: "Super easy & smooth flight. We left on time & arrived early."
Cons: "Nothing really. Honestly, I slept for half the trip, so it was pretty uneventful."

Pros: "I had a special meal and they were mindful to bring it and check that everything was okay."
Cons: "I downloaded the United app for entertainment but for some reason, I wasn't able to watch movies. It kept giving me an error. Make sure you download the app before the flight and that you have the latest version! At least they were playing movies and shows on the main screens."

Pros: "We didn't crash?"
Cons: "After much concerns and inquiries made bag did NOT make the plane! There is as no one to h love me to n white Planes for 45 minutes! No one at the counter? Wow! Finally supervisor Jill was able to track it down in Chicago where th y took it off the he plane as my carry on because they had no room l ft from the h limited space. After working very hard to get my bag of o White Plains that evening, supervisor Jill hung out an hour past her shift ended to get it on the last transport to my hotel. The transport blew herself by ft and never showed up or called the o say he wasn't coming back! I got my bag on he next morning just in tim for my event! I also was not credited my frequent flyer miles. Some glitch in the system. Overall I must rate my experience as a one star simply because the pilots got us there safely."

Cons: "Uncomfortable seats, inefficient food service and pricey, and entertainment is a rip off."

Pros: "The crew was very nice and polite. Service was prompt and excellent"
Cons: "Excessively long layovers. I came home with 3 broken ribs and had to endure a 11 hour layover in Japan and another 6 hour layover in San Francisco."

Pros: "Comfortable."

Pros: "Quick flight, beautiful day, interesting company sitting next to me very pleasant flight."
Cons: "The flight was overbooked and they were offering vouchers for later flights, wasn't a bad thing, though, I'd have done it."

Cons: "On board service!!!!!"

Pros: "On time/early"

Pros: "Great flight friendly person sitting beside me, would like seat towards front but my husband likes sitting in back , we had seats in row 27 & window seat for him he likes looking out. It was very enjoyable. Thank you"

Pros: "Direct flight was convenient"
Cons: "The crew on the outbound leg of the trip was unprofessional loud and disrupted everyone's sleep."

Pros: "Crew worked hard and were terrific."

Pros: "No charging docks on plane as military duffle bag open with clothing hanging out on arrival ~ not sure if anything stolen but the threat is very real and it's unacceptable for military bags to be delivered in that manner"

Pros: "Good crew. Nice ground staff in SFO."

Pros: "The pilot apologized profusely for our delayed departure, and offered us free in-flight TV. He made up time, and we arrived only 30 minutes late (take-off was delayed over an hour)."

Pros: "Nothing"
Cons: "Plane didn't leave until 2.5 hours after expected departure time and we never got an actual reason why. This also made me miss my connecting flight so I had to spend an additional 6 hours in the airport waiting."

Cons: "One of the fight attendants answered no to moving to an empty seat saying it was an Economy Plus seat but in less than 3 minutes another passenger freely occupied that seat. Really?"

Pros: "Noting"
Cons: "Bought the ticket from Lufthansa but the operator was United. Although it was known by the operator that there is a delay already at check-in, passengers where notified only at the gate. Delay was so long that most passengers would miss their connection. After standing an hour in line at the gate to book alternate connection, counter was closed and we were directed to another 10 min walk away. After another 1.5 hours without reaching a representative we had to rush back to the gate to board. In Frankfurt had to stay in standby for the next alternative flight. Luggage was delayed in the US for 2 more days."

Pros: "Easy quick boarding - attendants seemed to watch and keep the misc items from going into the overhead."
Cons: "Being woken up to see if I wanted water or food"

Pros: "Boarding was much more organized with lines marked for each boarding group. The crew was super friendly. Also, I received a whole can of cran-apple juice, which was much nicer than just a small cup. The tv options were also fairly priced for the options available."

Cons: "Long delay in San Francisco"

Pros: "Seats were comfortable. I passed out so couldn't take advantage of the food and entertainment. Nevertheless, I was comfortable enough to take a snooze. Despite the turbulence, Captain remained in control and ensured smooth safe travel."
Cons: "Sitting in the middle. And the bright light from the TV kept turning on because I would lay my arms on the arm rest. Also, airline attendants were not friendly. Maybe, they too needed to take a quick snooze."

Pros: "Crew"
Cons: "Seat did not recline at all. I have no idea if the entertainment was any good because I did not experienced it"

Pros: "I got from San Fran to Balitimore in one piece."
Cons: "Flight was overbooked, and my seat was one that was oversold. I still don't know how this happens, but it's fine. When I do get on, I'm literally wedged between a rather large man and the window. No ones fault, but comfort was horrible. Crew was nice enough, but I was uneasy when we were about to land, flight attendant reminded us to not take belongings in the event of an emergency evacuation. I'm all for being prepared, but please don't make me feel like we're about to crash."

Pros: "Part of personal device show of "By the Sea""
Cons: "San Fran to BWI unable to view end. Hubby watched Olympics I refused to pay for two devices."

Pros: "On time!"
Cons: "Many open seats but I was crowded into the back with several small children directly behind me and to the side who were wiggling, screaming, crying with parents correcting, chastising and singing to them. Thank goodness the trip was just over an hour and not any longer'"

Pros: "Very little to like"
Cons: "First : I bought Lufthansa tickets but was flown w United. Rude staff terrible food and unbearable seating no tv monitors per seat. I travel to Europe 4 time a year... This was without question the worse"

Cons: "Limited leg room. Seat didn't recline."

Pros: "Uneventful flight, on time performance, fast boarding"
Cons: "The main cabin entertainment was really bad, with picture freezeng once every few minutes for 20sec. Crew ignored it, movies mostly not watchable"

Pros: "The length of the flight was acceptable."
Cons: "My seat was moved futher back in the plan 34D, seats were smaller, knee space tight, the air back here was unpleasant (b.o.). Very noisy. The stewardess did not know how to operate the entertainment screen, finally she said I needed headphones, once I was hooked up volume up High I still couldn't hear the movie, to much outside noise, I thought the guy behind me was shaving. The Asian snack was dreadful no beverage available for awhile."

Cons: "There was a long time delay. The inflight crew seemed to have an issue with helping you and when you did finally get a stewardess/steward, they will tell you to wait. No hot towel and almost an 8 hour wait to get your meal on a 13 hr flight!!!"

Pros: "Flight crew"
Cons: "I couldn't believe that this long flight had NOTHING in the form of entertainment. No wifi to watch on your own device and no inflight entertainment. I was stuck in the middle of 2 people with a baby with nothing to pass the hours. Unbelievable!!!"

Pros: "United got my passengers from origin to destination on time."
Cons: "UA staff tried to intimidate my daughter into redesign sting her registered service dog as a "comfort aninal", and demanded that she describe the nature of the dog's service, IN DIRECT VIOLATION OF THE AMERICANS WITH DISABILITIES ACT. UA staff also, at the outset of the flight, attempted to confiscate all food and drink items from passengers, so that UA could immediately sell food and drink items to passengers."

Cons: "Seats were not comfortable, no individual tv screens"

Pros: "You can carry up to 16kg in your carry on. That's great."
Cons: "Food was below average and only twice during a 14 hours flight. Plus, no free snack available... you have to pay. I will think twice about travelling with United for an international flight."

Pros: "Movies were ok."
Cons: "Openly rude, almost argumentative staff. I was afraid to talk back because the last thing I want is any accusation of bad behavior on an airplane. But if this were a restaurant, the customers would get up and leave without eating. I've never had this experience on China Airlines or Japan Air. I will never use UA again."

Cons: "Seat could not recline, voucher was only a small fraction of the ticket fare that I paid. This is a business class seat."

Pros: "Lmnot full flight"

Pros: "on time arrival"
Cons: "power outlets were present but not functional. A real pity as I counted on it for my long trip to keep my portable devices. Lounge in Chicago does not have many outlets either and the next plane to Brussels either. This prevented me to keep my devices up along my trip preventing to work or watch movie as I wanted."

Pros: "No food provided except small snack"
Cons: "Completely full flight"

Pros: "Food was good, flight was early, and I watched three movies on my phone through the United app. No complaints here!"

Pros: "Nothing"
Cons: "Staff was unpleasant. Uncomfortable seats."

Cons: "Carry on bag cost of $45."

Cons: "Seats did not recline and were very uncomfortable. Couldn't believe you had to buy your drinks. No snacks. By the time that I paid all the a'lacart it cost me more than a flight with Delta or Southwest. Will not be flying Frontier again."

Pros: "the flight was cancelled after being delayed for 4 hours. it was delayed because "many passengers booked the flight", and then it was cancelled because the window crack was found. fronter did not partner with other arilines, so the next one was available in 3 days. i had to cancel my whole flight and book last-minute flight with United and left in an hour. I had to pay $1000 extra for this flight. Frontier really ruined my day and my finanicals."

Pros: "Nothing!"
Cons: "Delayed 3 hours, then told flight was cancelled! Frontier did nothing for passengers! Return flight had over 2 hour delay! We changed carrier and had no problems. Will never fly Frontier again!"

Pros: "Nothing!"
Cons: "Everything! Had to pay $40 for a carry-on, $35 to pick my seats in advance, $35 to check a bag, over 110 in fees before I got on plane. $2 for a Coke- water was free but they were rude when you asked for it. No tray tables, seats didn't recline, Felt like I was on a bad school bus."

Pros: "There was a flight delay due to bad weather and since I would miss my connection, I had to be rebooked onto another flight. The whole process of rebooking was tedious and annoying"
Cons: "The customer service and the airline staff."

Pros: "Not much. The crew was fine. Also customer service people I spoke with were good. One was excellent. Seats themselves are comfortable but the closeness of the rows is horrible! NO ROOM!"
Cons: "I cannot stand the fee structure of charging more than any other airline for EVERYHING! $60 to pay for one carry on bag if it is at the gate!!! You guys are simply mercenary. It looks like others hate this also from the reviews I can see. Your fares are not less! to justify the additional charges! LEG ROOM WAS LESS THAN ON ANY OTHER FLIGHT I HAVE EVER TAKEN. I have never been so squashed in a plane. I will not fly frontier again if I can help it."

Pros: "Great leg room, clean, on time and great staff"
Cons: "Everything was great."

Pros: "except for the food and what entertainment it was over all good"
Cons: "could not pay cash"

Pros: "Had to cancel flight because of long delays. Actually went smoothly and got an appropriate refund. Wasn't expecting that to be easy but it was."
Cons: "Carry on bag fees made it more expensive at the end. First flight was delayed 6 hours ended up having to buy another flight last minute"

Pros: "I like that they flew me to where I laid to go."
Cons: "The crew was discourteous the entire flight--yelling at passengers and not accommodating. At least the flight was $38"

Pros: "Overall great flight."
Cons: "Unfortunately, the flight was delayed for an hour and 14minutes, and when waiting for baggage for over an hour to come out."

Cons: "Late late late. Delayed on both ends of both flights! It wasn't even raining! No explanation or support from airline. It's cheap for a reason: because it's a worthless airline! Just pay the extra money for a real flight and you might actually get there at a reasonable time. Also: you have to pay for carry on items, use that money towards flying on a better airline!"

Pros: "The flight attendants, specifically the two at the head of the plane, were absolutely terrific and so nice. I haven't had great experiences with flight crews recently, but those two women deserve some praise. Unfortunately, I don't recall either names."

Cons: "The fact that the flight was delayed by 3 hours for some "minor maintenance" problem. You want to do your maintenance on the passenger's time. You suck."

Pros: "They make you pay for carry on"

Cons: "The flight was cancelled so I was unable to experience it."

Cons: "They forced me to pay $60 at the gate for bringing a carry on bag in the plane. Such a dishonest racket!"

Cons: "Wish I had done more research never flying frontier again they charge ridiculous prices for every single bag you bring"

Pros: "Nothing."
Cons: "Rude flight attendant, old plane,expensive fees. Will never fly again."

Cons: "In San Francisco we were not charged for our carry-on luggage, so we did not purchase the outrageous $40 fee prior to our Phoenix departure. We were stopped at the gate and told we had to pay for our carry-on luggage and because we didn't pay the fee in advance we were charged $60 for our carry-on. Person at the gate said "I can't help what they do or don't do in San Francisco. Get it together Frontier. We will NEVER fly Frontier again!"

Pros: "The ticket cost is slightly cheaper than other major airlines, but you have to pay for everything, including carry-on. Include them in your ticket price and you will end up paying more!"
Cons: "They charge you for everything! Uncomfortable seats"

Cons: "The new narrow seats that don't reclind back. Damages my bag again."

Pros: "On-time departure and arrival, no-hassle boarding (expected a RyanAir like treatment w.r.t carry-ons, etc"
Cons: "seats don't recline"

Pros: "The crew was nice. Never have I been so delayed with little to no information, but they were doing the best they could.."
Cons: "Horrible delays, no information, tons of hidden costs, and did I mention horrible delays?!"

Cons: "They were delayed due to a mechanical issue, making me nearly miss my connection. This airline has rediculous fees for their luggage, they charged me $290 for 4 BAGS all well under weight limit. My luggage missed its connection to Sioux Falls and they wouldn't send it until Christmas Eve, two days after I landed. And it didn't get there until Christmas Day evening, ruining my family's Christmas. I will never fly with them again."

Cons: "$45 to check my carry on. Just give me the bottom line when you charge me instead of saying I am getting a deal than charging me even more once I carry my own bag onto your plane."

Cons: "Fronteir's cabin is pretty bare bones. Plus they lost my luggage. Having no jacket on a freezing night in Denver was brutal."

Pros: "I was taking my parents to Colorado because they are 82 years old and they need help. I requested two wheelchairs. They only provided one and the guys insisted that my dad walk because we have enough time. I booked and early ticket at 5pm and it was a delay of almost 6 hours. We got to Denver in the middle of the night and we had to drive 2 hours to Colorado Spring.We had to get a hotel. My parents couldn't sleep at all. Everything because there was a very long delay in San Francisco and they told me it was because bad weather which we checked in both cities and it was not an issue at all. The lady on the desk told me once "if you want to know more about it, you could back through security and check it out" That was rude and nonsense. I was just asking if she could check if there is an early flight for my parents."
Cons: "I would like some sort of compensation for the huge inconvenience."

Pros: "Short fly thanks Big airport (as well as services)"
Cons: "Very late Not organized Hidden fees ...."

Cons: "Flight from San Francisco to Las Vegas on a Friday night: - 4 hour delay - After heading to the gate to finally board our flight (~30 minutes before departure), we overhear the desk agent telling the people coming to the desk - not even by announcement over intercom! - that the gate had been moved to the INTERNATIONAL TERMINAL. - This meant that we had to run across the airport and go through security again! The agent also neglected to tell us that mobile tickets for Frontier (even on the app?!) were not accepted at the international terminal. On top of that, you would think they'd have at least one agent available at the main counters to deal with any resulting problems. Two friends who could not get in with the mobile app and had to run around to even OTHER sister airline kiosks just to find someone to print the ticket (even the touchscreen kiosks wouldn't print). We even had a friend that did get through security run to the gate to talk to the boarding agent and was VERY rudely told to just "go ask TSA how to deal with it." - By the time everyone arrived to the gate (~30 minutes PAST the projected boarding time), they announced that they would just need a little time to just clean up and turn around the airplane. We take a look aside to see that there isn't even a plane at the gate! Overall, as cheap as these seats might get, don't waste your time your time. You get what you pay for, and a headache to add."

Pros: "Our flight attendant sang us an original song about turbulence"
Cons: "Paying $30 to check a bag and waiting an hour for it to show up at the carousel"

Pros: "I found that a $16 charge to chose a seat was rediculous. I understand a baggage check but a price for a seat should be included in the price of the ticket. Otherwise what am I paying for than a seat on the plane"

Cons: "Great experience but for the exorbitant bag check rates"

Pros: "The crew was as helpful as possible, very kind and clearly as frustrated with the situation as we were, and did their best to make sure the rest of our flight was comfortable."
Cons: "My flight was delayed for three hours. We were loaded on to the plane, then told it would be another hour, got off the plane, got back on, and it was still another 20 minutes until we started moving. It was tiring, frustrating, and caused a lot of issues with my ride in Phoenix. I do understand, however, that many of the issues were unavoidable, such as mechanical problems and missing mechanics, but it was frustrating nevertheless."

Cons: "I had a pretty unpleasant experience with Frontier on 12/21/15. Rain in San Francisco caused flight delays. Go figure. Frontier kept us waiting for six hours then cancelled the flight. They were rude; they didn't help their customers, including families with kids, get on other airlines; said they would try to getpeople out of SFO in the next couple days! When I realized I would not get to the wedding I was trying to attend, they siad they wouldn't refund my money' When I insistedon a refund they then said there would be a $19.99 cancellation fee. Eventually, they agreed on a refund. Pretty poor way to run a business. On the other hand, when I needed to cancel my Enterprise car rental, I was able to do it in less than two minutes over the phone - no hassle."

Cons: "I stood in line to check in for over an hour. At one point there was ONE agent working the desk. Easily over 100 people in line. The line to just drop off bags was also hideously long and slow-moving. It wasn't due to the holiday rush. The rest of the ticketing desks at other airlines were clear. Get it together, Frontier."

Cons: "Worst flying experience of my life. Terrible terrible airline. Had everyone wait for a 5 hour delayed flight the. Changed plane had to remove people from the flight then after reissuing each person seats and boarding cancelled the flight once everyone was finally on board. Never ever again."

Cons: "This is the worst airline experience I've ever had. How do you not use electronic tickets? Waited an hour for someone to show up to work at the counter- also all the 4 kiosk ticketing machines were out of order. Then my flight was delayed almost 4 hours. And it was uncomfortable. And you have to pay for everything. I will never fly frontier again!!!!!!!!!!"

Pros: "The crew was fine."
Cons: "It is incredibly dishonest to not include the 40$ fee to carry on any bag, and 13-20$ fee to choose a seat, bringing up a 60$ per flight leg additional cost. That means roundtrip tickets can easily be 100$ more expensive than listed, making other, more reputable airlines actually cheaper. Not to mention they do not take electronic tickets like every other airline, and when the flight was delayed, I went to have my ticket printed and no one was staffing the desk and no automated kiosks were available. I managed to flag someone down and they wanted to refuse to print me one because "my flight was listed as earlier" despite me being emailed by them that the flight was delayed. I eventually got to my destination, but I will never book a flight with them again. Let's not even mention charging for water, the plastic seats on the plane, etc. Terrible airline."

Pros: "pleasant atmosphere and crew energy. perfect sized tray tables and easy way to adjust them. Nice, too, to know that now one was either going to get squished in their seat by person in front reclining, or person in front reclining to be alarmed by person behind trying to stand up."
Cons: "Would like to be sure that any announcements by crew are made by ones with clear English dialect and appropriate pausing so all can understand. (not saying that was an issue on this particular flight....but I noticed it during my trips this month...)"

Pros: "The flight was extremely delayed and airport staff did not clearly communicate late gate changes or updated boarding times. There was mass confusion and the whole experience was quite unpleasant."

Pros: "Frontier has the absolutely least comfortable airplane seats I have ever used."

Cons: "4 hour delay makes dick a dull boy Never again, frontier"

Cons: "If it weren't for having had so many bad airline experiences, I would rate it lower. And hour delayed for a 2 hour flight. Frontier seems reasonably priced, until you factor in the hidden fees - $30 for a checked bag, $35 FOR A CARRY ON, $ to choose ANY seat. Not much legroom and seats didn't recline. At least they didn't lose my suitcase."

Cons: "A $30 ticket ended up costing me over $200 because of all the extra charges for baggage. Never once have I been charged to take my guitar on a plane but they wanted $60 at the gate. Not to mention that I flew Frontier with my guitar for free 3 weeks before this happened. I will never fly with Frontier again. Do yourself a favor and choose an airline that is upfront about what they will charge you for."

Cons: "Lots of delays"

Pros: "I was easliy checked in"
Cons: "It was more then an hr late The plabe shook all the ride long It felt terribly unstable"

Cons: "I spent the entire day in the airport b/c they strung us along 2 hours at time. Then when the plane was finally ready they had to get a new staff for the plane and delayed us another 4 hours. Couldn't they have planned ahead and found a staff before the plane was ready?!? Or if they had just told us upfront the repair was going to take 8-12 hours we could have made use of our day. Losing a whole day of productivity when you own a small business is catastrophic. Frontier really screwed me over."
