Airline reviews

Pros: "The accommodation to the military service members!"
Cons: "Air fresheners should be used on the airplane."

Pros: "Delta is doing a great job keeping everything calm and clean during this pandemic!"

Cons: "Nothing all excellent"

Cons: "It was great! Nice job Delta !"

Cons: "Wouldn’t change a thing! I don’t always fly! But when I do!! I fly delta!!"

Pros: "Christina brown was amazing at gate"

Cons: "The main economy seats were far too narrow."

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: "DTW to FLL, plane was delayed coming from BOS to DTW 5 hours for BOS weather. The plane arrived & they announced they would turn it around ASAP. They started the boarding process & then stopped it stating that a crew member had timed out. Delayed hour to FIND one. Shortly after delayed overnight."

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

Pros: "Flight attendants were very friendly."

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: "Entertainment"
Cons: "Boarding at JFK.Always messy"

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: "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: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."

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

Cons: "My flight was delayed, which would have caused me to miss my connecting flight. The customer service person was not at all helpful, and told me there were no other flights available on any airline until the next day. However, I was able to go online and book another flight immediately...which means that she was either being disingenuous or actively undermining efforts to get me home in a timely fashion. Very disappointing and as a SkyMiles member would have thought there would be some level of common courtesy dealing with a non-weather related delay that drastically impacted my travel plans."

Pros: "Everyone who has a kid knows how challenging certain things can be in a flight and for me the combination of a night flight interrupting my baby’sschedule + a full flight it equalized disaster. My daughter could not get comfortable for the love of life and I just felt horrible and frustrated and what sucked most was the 9 year old and her obese father siting in our row that kept giving us weird looks."
Cons: "There’s NO room in planes between seats. It’s 2018 and new planes must be done ASAP to accommodate people better. I’m 5’1” and 110 lbs but adding my 25lb daughter siting in my lap before she turns 2 is absurd to expect that it will be comfortable whatsoever for us or the people breathing next to us. Please DELTA, lead by example and make sure your planes are designed with more room in between and around the seats. In my opinion, every seat should be first class."

Pros: "In a pinch they were able t"

Pros: "Everything was perfect !! Staff friendly"

Pros: "Good customer service"

Pros: "Great in every way"

Pros: "It got me home, eventually."
Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"

Cons: "Check in lines were crazy long"

Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"

Pros: "The entertainment unit allowed me to watch the Denver Broncos game live which helped lessen the delayed departure and uncomfortable seating."
Cons: "Uncomfortable seating....too crowded!! We had a delayed departure by 30-40 minutes because of a computer download issue. Too many folks carrying carry-ons delayed boarding. I wish folks were not encouraged to go that route but to check baggage. This time of year gets even tougher with folks carrying Christmas presents and over sized personal items. Ugh. Not fun to travel this time of year."

Pros: "App is good and convenient to use."
Cons: "The app went down just as we were getting ready to board and luckily i had a printed pass and it took some extra time to check in."

Pros: "really helpful and friendly service and nice seats."

Cons: "We left late, it was delayed then maintenance issues. Twice. Seating was very tight and uncomfortable, no movies or entertainment at all. U.S. flights are the worst. Even on short flights with aeromexico outside the U.S. you get movies and food. Zero stars for comfort, food and entertainment."

Cons: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."

Pros: "Friendliness of staff. Second flight was a newer plane - sweet!"
Cons: "For a long flight perhaps a little more in the snack department."

Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"

Cons: "I liked it all"

Pros: "The boarding agents were especially helpful and friendly to my disabled wife, travelling in a wheelchair."

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

Cons: "long wait and delayed flight"

Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"

Pros: "Very professional and caring."

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

Pros: "Everything was smooth from start to finish, and the flight landed 10 min. early! Can't ask for more!"

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."

Cons: "Too much to write down. Start at the counter and work yourself to the plane. I hope you get it right eventually, I’ll be flying Southwest"

Pros: "Plane wasn’t full and left and arrived early!"
Cons: "Offering some kind of beverage"

Cons: "Feed me"

Cons: "IFE was not streaming movies, WiFi on but not loading"

Cons: "Less crowded."

Cons: "A bigger plane."

Cons: "Baggage handler lost my bag, grabbed it off plane cabin, never found"

Pros: "Boarding was quick and well organized. Crew was friendly."
Cons: "By the time the snack service was completed, the plane was already descending and the crew had to pick up the service items before people had a chance to finish."

Pros: "Wonderful flight attendants in both our flights."

Pros: "Left on time and arrived early"

Cons: "Great flight"

Cons: "Flight currently delayed 3 hours! No help booking another flight or compensation or way of getting back to NYC in time."

Pros: "Crew was great. Seats could be a bit wider"

Pros: "Crew was great. Boarding was easy."
Cons: "Easier option for entertainment."

Cons: "To many delays."

Cons: "Flight delayed, interior of aircraft was deteriorating"

Pros: "Great service and sweet attendants"
Cons: "Person next to me was a little large and it was uncomfortable."

Pros: "Nothing"
Cons: "Flight was delayed six hours. Flight crew arrived late further delaying trip. Connecting flight missed. Promised hotel reservation by American were non-existent when arriving in Dallas. Had to try to sleep in airport. Will never willingly fly American again"

Cons: "Delayed for mechanical."

Pros: "I loved the attitude and helpful approach of the female flight attendant working the AA gate for the flight I took from DFW to COS last night (6/13). Truthfully, it was almost like I was back with Southwest. She was kind, calm, polite, efficient, and capable. Very rare in my experience with American Airlines yesterday. Interacting with her was refreshing."
Cons: "Getting home to Colorado Springs at 11:30 PM, taxiing for 15-20 minutes, and then waiting another 20-30 for checked luggage! Never have I waited that long during and after a Southwest flight! AA could truly learn something from their more modest counterpart. I have all but decided to resume my drives to Denver every other week rather than risk more and more time and poor experiences with AA flying in-and-out of Colorado Springs."

Pros: "Arrived on time despite late departure"
Cons: "Bumpy ride in CLT but uncontrollable"

Pros: "WiFi was on the flight. Free with TMobile."
Cons: "Easy and fast flight"

Pros: "Everyone was nice"
Cons: "No gluten free snacks. Flight was late"

Pros: "Great service"

Pros: "Flight crew very friendly."
Cons: "No entertainment so 1 star rating. Kind passenger switched seats so I could sit with my husband and son. Would have had to sit behind them if not for her. Paying extra for isle seats was a surprise."

Cons: "Wish they had told me there was a shuttle to other side of airport. Had not been to this airport in many years."

Pros: "We arrived on time."
Cons: "These planes feel like they are made of Legos. They are absurdly tiny and uncomfortable (and I am a small woman). Hot and stinky when boarding and no room for you or your carry on luggage. The days of glamorous air travel seem very far away."

Pros: "Efficient, fast boarding and quick departure."
Cons: "Leg room was minimal. I am tall."

Pros: "Quick flight"
Cons: "seating too small."

Pros: "Other passengers were friendly?"
Cons: "I was traveling alone with my tired, cranky 13 month old. I get that it's no fun for anyone, including me, to have a tired toddler on the flight! But from the moment we boarded the flight attendant was unfriendly and unhelpful. I asked for help putting a heavy bag in the overhead compartment. She half-heartedly tried and then told me it "didn't fit". By simply turning it on its side, I was able to easily make it fit, but it was uncomfortable for me to have to do so while also holding my baby! The flight attendant then commented that I couldn't have the child in a carrier during the flight (something I am well aware of!). She also neglected to offer us a snack later on. Overall, she was rude and inconsiderate and made a difficult trip more unpleasant."

Pros: "I liked that the internet connection was free because I am a T-Mobile customer."
Cons: "Boarding the plane was a bit clumsy. I felt like everyone was tripping over each other since the front of the plane was boarding first."

Pros: "We didn't crash."
Cons: "No safety briefing for infants, rude gate staff, primitive fleet, terrible customer service at all levels."

Pros: "The PWM airport, ALMOST makes air travel tolerable. Great little airport. Crew was pleasant, Seemed to enjoy their work. That, alone makes a huge difference in an industry that truly doesn't put customer service anywhere NEAR the top of the priority list."

Pros: "Quick and fast. Slept through the landing and woke up to everyone gone and was in a rush to get out, but forgot my phone and passport, and I asked about it they went back there and looked for it for me and got it back. Over all good experience."
Cons: "Wish they offered water, but since it was short it made sense."

Pros: "Everything went more smoothly this time than on our way to Phoenix. Even though the airport was quite crowded they had enough staff to get us through baggage check fairly quickly. They flight was smooth."
Cons: "No problems on this leg of the trip."

Pros: "Punctuality"
Cons: "Small plane with no leg room"

Pros: "Everything"
Cons: "Nothing"

Cons: "Flight was good until, after arriving 30 minutes early to PWM, our plane had to wait about that much time for our gate to open. Once pulling to the gate we waited another 15 minutes for someone to figure out the walkway and open the door tom the plane-- all with no communication from the crew."

Cons: "i decided to purchase a separate direct flight at a different time instead of changing my flight, only to be informed later when i tried to hop on the back end of my original flight, that they had canceled my ticket since i hadnt boarded on the front end of that flight. i had spoken to a customer service rep about my option before purchasing the extra ticket, and she did not mention that this would be an issue. then i had to pay extra to get back on my original flight."

Pros: "Quick and easy"

Pros: "American Airlines is my favorite Airlines to fly. There is a little more leg room and the seats are a little wider. The staff is very professional and courteous."

Cons: "My flight date was changed because of a medical issue with my grandson, and I was outraged by the amount of the change fee."

Pros: "The flight was on time, and the crew was friendly."
Cons: "The boarding was very disorganized and took a long time, and there was no silverware on board, which I needed."

Pros: "Not applicable"

Pros: "N/A"
Cons: "It took so long for me to leave this airport. I got there around 11:30pm and my flight wasn't till around 9:45am the next day and so when it came to that time they had cancelled my flight so I got another ticked for around 2pm and they didn't board that flight till around 4:30. My experience there was to much to handle. I was supposed to get to Colorado Friday night but didn't even get here time Saturday afternoon. Really upsetted me because I leave wednsday so I don't have enough time to be with my boyfriend. I honestly don't think I'll be flying American Airlines again"

Pros: "I used points to bump up this flight to first class and was very grateful for the delicious food and extra room. We received good service from attendants who checked on us often to bring extra drinks and answer questions. I see now that it's worth the extra money/points to fly first class. Thank you for making it a great experience!"
Cons: "I felt the flight attendant who first served me was a little brash. We were seated for what seemed like extra time before takeoff so I ordered a mimosa when asked if I wanted a drink. She seemed reluctant to give it to me so I wish she had explained that there wasn't much time or explained any hesitations that she was maybe trying to hide from her expressions. I was only 1/3rd finished with the drink when she practically grabbed it from my hands and said she had to take it away. A warning would have been nice, I could have finished it faster. Then during the flight when I ordered another one so I could actually enjoy it, she still seemed hesitant/judgmental and finally said "that will be the last champagne the plane has." It was an awkward experience that I didn't appreciate. However, this same attendant seemed more friendly throughout the flight and was kind and helpful."

Pros: "The flight attendants were nice and the plane was on time."
Cons: "I tried to switch my flight to an earlier time. First, they charge $75 (Southwest is always free). Second, the gate agent charged me and let me board, but her boss came on the plane and pulled me off because I wasn't Executive Platinum status! The plane took off with an empty seat and I had to wait two more hours for the first flight. When I complained to AA about it, they sent me a $50 voucher. I don't plan on giving any business to AA for the rest of my life."

Pros: "Nothing"
Cons: "I never even made the flight because they kept jerking us around"

Pros: "I fell asleep on the trip so that was nice."
Cons: "The seats are pretty uncomfortable for tall people."

Pros: "Crew was very accommodating in light of the maintenance delay. Especially for those of us with small children."
Cons: "Look, delays suck. We fly about only once a year, and we ALWAYS have a delay. ALWAYS. Air traffic control at Newark will delay a flight for a hangnail."

Pros: "Very friendly crew."
Cons: "This is a small airplane. I would like to see United insist that people check large bags."

Pros: "Not much"
Cons: "Cheap seats. And why were we not seated together when we booked way in advance?"

Pros: "The plane was clean, the pilot and attendants were pleasant."
Cons: "Rules are rules. Yet, at least ten people brought on more than the designated one carry-on bag and purse. Flight attendants shouldn't have to deal with those poorly mannered passengers who think they deserve special treatment. Otherwise, it was all fine."

Pros: "It’s existance. Informative capt."
Cons: "Late almost 3 hours. Sketchy bev service. 50 seat RJ."

Pros: "Nothing"
Cons: "Flight got cancelled again and again then call customer service but he doesn’t know anything about information. Totally ruined my day"

Cons: "3 hour mechanical delay"

Pros: "An early departure!"

Pros: "Nothing was good about this airline with the exception of the baggage crew that finally helped me in Washington Ronald Regan Airport"
Cons: "My flight out of Portland was canceled and it took hours to rebook. I had to fly American Airline to Washington DCA where I roamed the airport at 9pm looking for someone from United. The crew in Portland ME told me the gate person would have a hotel for me.... The baggage crew had to help me."

Cons: "I only made it as far as Chicago, and my bag was fairly comprehensively lost as I did so"

Pros: "Helpful staff and smooth flight. No connections or Hassels"
Cons: "Snacks"

Pros: "AT THE TERMINAL IN PORTLAND THE ATTENDANTS WERE SUPER HELPFUL AS I WAS CONFUSED ABOUT GETTING MY TICKETS."
Cons: "JUST BEFORE BOARDING THOSE OF US PASSENGERS NOT ALREADY BOARDED WERE TOLD WE COULD NOT BRING OUR CARRY ONS WITH US AS THERE WAS NOT ENOUGH SPACE TO STOW THEM OVERHEAD. SO WE WERE TOLD TO SEND THEM DIRECTLY TO OUR FINAL DESTINATION. WHEN I BOARDED THE PLANE I COUNTED 7 OVERHEAD STORAGE BINS ON THE OPPOSITE SIDE TO MY AISLE WHERE I WAS SEATED WERE NOT FILLED AND THERE WERE SEVERAL SUCH BINS ON MY SIDE OF THE AISLE (I DID NOT HAVE TIME TO COUNT THEM BEFORE I SAT DOWN). I ASKED AN ATTENDANT WHY THIS WAS SO GIVEN WE WERE TOLD THE BINS WERE FILLED JUST AS WE BOARDING FROM THE DEPARTURE AREA. SHE WAS POLITE AND SAID SHE WASN'T SURE ABOUT WHO MADE THE ANNOUNCEMENT IN THE TERMINAL BUT THAT IN ANY EVENT MY CARRY ON WOULD ARRIVE SAFE AND SOUND IN VANCOUVER - IT DID BUT WITH MY BOOK FOOD SNACK WHICH i HAD INTENDED TO USE WHILE ON MY WAY TO CHI. AND VAN."

Pros: "First time first class flyer. It was great!"
Cons: "Being separated from my wife in seating when we booked before others that we talked to!"

Pros: "The flight attendants. Especially Meagan and Heather. Amber was a,sweetheart too. I had the same attendants 3 out of 4 of my flights that weekend. So cool. When they realized it was me again they spoiled me rotten. So good I feel like unless I have those 3 as my attendants I won't fly United again"
Cons: "No food options. No free food"

Cons: "Really awful, disorganized and unapologetic."

Pros: "Wi if!"
Cons: "Uncomfortable seats"

Pros: "Flight did not happen"

Cons: "Very bumpy ride....but I realize that can't be helped"

Pros: "Bigger jet, more room. I was able to keep my carry on with me in the over head bin. Friendly staff. Very clean cabin."

Pros: "Stroopwaffle!"
Cons: "Cramped plane. Not enough space. Late boarding and then sat on the tarmac for a while."

Pros: "Not a single thing!"
Cons: "Arrived late"

Cons: "The flight was cancelled so I'm on stand by for who knows when"

Pros: "The crew was nice and the area was clean."
Cons: "I didn't like the fact that before boarding they offered to check peoples bags for free because so many people were trying to take ridiculous sized bags onto the plane. I always pay to check my bag . That process took for ever but we did still arrive on time."

Pros: "Both flights were early landing which was nice everything moved smoothly"
Cons: "I didn't have an assigned seat in the 22nd flight so when they called I asked about they said wait for ur flight to be called so I went and Sat back down til they called me by name so almost missed my flight because the communication with the staff needs improvements"

Pros: "We stood in line forever to then be told the clerk couldn't ch we ck us in. When we tried the kiosk it didn’t work. Long story short we missed our flight due to their poor organization of the line and crowd."
Cons: "The confusion caused by lack of direction from the staff."

Cons: "Seating next to the bathroom is gross"

Pros: "Friendly and polite! Crew."
Cons: "Middle seat. Space too small."

Pros: "Couldn't really figure out your Wi-Fi system so I just read a book"
Cons: "It's not really easy to set up your Wi-Fi system through the United app"

Cons: "No agent to check in when I arrived at airport. Only at gate. No advance check in or advance seating. Allowed passengers to have more than 2 bags. Flight was late. No help getting to next gate or holding aircraft. Absolutely uncomfortable sitting."

Pros: "Flew on Delta Airlines"
Cons: "Had to run to Delta and barely made that connection."

Pros: "Updated interior. Those new seats make it feel like a lot more room."

Pros: "That I got a refund, although that should be a given"
Cons: "Had to purchase new flight day of, as I was told of flight cancellation 5 hours before leaving to the airport. I then had to spend $500 on a new flight, and one of the connections refused to let me on the plane. Stil not home."

Pros: "Pleasant crew"

Pros: "Larger plane, great comfort. Nice staff!"
Cons: "You have to pay for wifi, nothing to look at during flight."

Pros: "I had an empty row."
Cons: "Waiting for boarding an extra 30mins. Waiting for departure an extra 30mins. All after having my gates switched, and walking accros the concourse just to get to it."

Cons: "The 2 hour delay"

Pros: "I like that they waited for me before they took off"

Cons: "Canceled flight, booked me an impossible connection, put on stayby when I get the tickets months in advance. Offered no vouchers and made me fly out on a diffrent day. Hs aircraft delays on all flights"

Pros: "Nothing."
Cons: "Never flying United again. On my way to the airport in Portland I got a text from United that my flight to Newark had been cancelled and there was no way to fly me out of Portland to San Diego that day. My sister had to drive me to Boston so I could catch a flight to San Francisco, which took 6.5 hours because it flew over most of Canada for some reason AND had three babies that cried from start to finish. Oh and because I was a late addition, I had a middle seat. The second I turned my phone on after we landed I had another yet another text from United saying that my connection to San Diego had been delayed three hours and wouldn't take off until 11:15 pm."

Pros: "Nothing"
Cons: "Payed to upgrade seat was not comfortable and person next to me kept moving onto my side. Flight was 2 hours late so I missed my connection and had a terrible time to find a flight home. United staff was not helpful and kept telling me to go somewhere else for help. No food was served only tiny packet of way too spicy pretzels. Sat on the runway for an hour. Flight crew said 15 min and it was much longer. Crew seemed to be really confused."

Pros: "Polite staff"

Pros: "Great"

Pros: "Everything was perfect"

Cons: "Boarding was 15-20 minutes late, no one at the counter. Bumpy flight due to turbulence due to weather."

Pros: "Staff excellent"
Cons: "Passengers space is insanely small, staff work under restrictive conditions"

Pros: "Female pilot was the best I've ridden with"
Cons: "The delay was horrible."

Pros: "I made it to my destination"
Cons: "It’s Frontier so it’s not supposed to be amazing. Not having to pay for a drink of water would have been nice though.."

Cons: "A soft drink that doesn’t cost money!!"

Pros: "Everything"
Cons: "Nothing"

Pros: "Nothing"
Cons: "Window seat and a beverage"

Pros: "The crew was great, the prices fantastic and everything whet extremely well. We even arrived in Denver early. The flight crew did a great job of keeping turbulence down despite some conditions that were less than easy to navigate. For a no frills flight, this was fine."
Cons: "I miss the frills although they have them available all at a cost during and before the flight. If you need all the frills I would probably go to a more comfortable venue. If you bring your drink and snack and don't mind not choosing your seat, etc., this will work just fine."

Pros: "Is good"
Cons: "Yes"

Pros: "Nothing"
Cons: "Everything"

Cons: "They need to stop having so many delays"

Cons: "Bathroom was beyond tiny"

Cons: "So grateful for all of the help we received!! Thank you!"

Cons: "Ridiculous surcharges, no water, no coffee"

Cons: "Check in"

Cons: "Free water"

Pros: "Frontier was smooth and efficient, didn’t have any issues."

Pros: "Nothing"
Cons: "Delays, gate changes, lack of notification, last minute changes."

Cons: "Frontier is an airlines that doesn't care about its customer. Period!"

Cons: "one hour late"

Cons: "Late again"

Cons: "I had to pay $50 for my bag"

Pros: "I did not like anything about this trip. The check in process was a pain. The boarding was chaos... (Of course, same 2 careless ladies were in charge."
Cons: "I did not like anything about this trip. The check in process was a pain. The boarding was chaos... (Of course, same 2 careless ladies were in charge)."

Pros: "Went exactly as described"

Pros: "Plane interior was bright and new."
Cons: "Baggage retrieval. Chairs don't recline."

Pros: "The staff was a well oiled machine! Very funny & accommodating. They were all very friendly & helpful to all of the passengers. Everything was clean & orderly."

Pros: "Early, friendly staff"
Cons: "No WiFi"

Cons: "Flight attendants inattentive and forgetful."

Pros: "The first"
Cons: "This flight was canceled at the last minute and all passengers were told they needed to find another flight because the airline didn’t have any to rebook them on. Passengers had to pay out of pocket for new flights. Frontier said they would reimburse but I haven’t seen anything yet."

Pros: "Not applicable."
Cons: "Due to mechanical error, the flight was delayed, we missed our connecting flights, and customer service was rude. With all the added fees, my total flight round trip came out to $502.90, so the options given to me as partial refunds did NOT make sense ($180 if I refunded my entire return flight, which is way less than half my overall cost, or per customer service at my connecting location, “you’d be lucky if you got $80”, which is way less than a quarter of the overall cost). My connection was at Denver and my final destination was Seattle. My options were to fly to Portland, OR and figure out the rest on my own, at my cost. Or book the next flight to Seattle, which was 24 hours later. I got a voucher for up to $150 for hotel, but absolutely no assistance finding and booking a hotel, especially since they were sold out (I was looking for hotels just past midnight) or cost over twice the voucher. Am NOT flying Frontier again and I have shared my experience with friends, family, and co-workers and have strongly advised against this airline."
