Cons: "My flight was delayed almost 3 hours. Not good. Once in the air it was fine."

Cons: "No US carrier seems able to master smooth boarding without standing waits."

Pros: "comfort plus really makes a difference"

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: "Boarding was easy, plane clean, snacks good."
Cons: "Small plane but that’s not really fixable"

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."

Cons: "Waited in the runway and then taxied forever"

Cons: "Very little leg room."

Cons: "."

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: "The staff really helped me out getting on standby so that I didn't have to wait for a 9 hour layover. Overall great experience and great staff."

Pros: "In a pinch they were able t"

Cons: "Economy is very tight quarters."

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: "The baby"

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: "Nice plane, smooth flight, flight was on time in spite of the disaster in Houston."
Cons: "There was food listed in the book but it was never offered. On a 4 hour flight, this is too long! Wifi was broken...I bought a $20 pair of earbuds in the airport specifically to watch movies and was never able to use them."

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: "On Time"

Pros: "The plane was not so new or good"
Cons: "The plane and the atention"

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."

Cons: "Late taking off"

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

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: "Board the back of the plane first"

Pros: "On board crew was helpful and polite considwring our circumstances."
Cons: "Our flight was delayed 3xs (non weather) they said we would miss our connection (I didn't think we would) THEY rebooked a later flight. Of course we landed in time for our original flight. They refused to let us back on our original flight. Put me in touch w/ the help desk who after talking in circles admitted it was their mistake but he had no authority to help. FINAlly & only because others missed their flight we were given the option to go. Crew misplaced our luggage and sent it on a flight we were never supposed to be on, and the bad experience with delays of hours on end continued coming home. (Mechanimal non weather) WE WILL NEVER FLY DELTA AGAIN!"

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

Cons: "Spacing people out until this covid is over"

Pros: "It was standard AA service"

Cons: "Sat waiting for gate for 30 min"

Pros: "Boarding was fairly quick and on time. Transfer in Phoenix was no problem. Luggage arrived OK."
Cons: "Seating is too small and too close to next rows. Unhappy with having to pay for seat assignments and checked bag while watching gate agents refuse to enforce overhead bag size limits."

Cons: "Only pretzels, came eat refined flour, nuts or something else would be great."

Pros: "Horrible staff at LAX boarding gate. Been treated horribly by incompetent and rude AA staff."

Cons: "Everything. Had to sleep overnight in airport and was late coming home."

Pros: "Staff was great!"
Cons: "Seats were really uncomfortable up and reclined. Overhead baggage was full by the time I boarded and there was no enforcement of the carry-on baggage sizes... This needs to be addressed and contributed to our lack of comfort, noting this was the last leg of an 18 hour journey. My body still hurts today after a good nights sleep."

Pros: "The people in fayetteville treated my William well. Thank you fayetteville, and shame on you Denver."
Cons: "When we got to Denver there was no one to help William off the plane. We even called ahead of time to make sure someone would be there with a wheelchair. The captain of the plane had to help him off the plane. It was so sad. William was so embarrassed. When it was time to board still no wheelchair. He had to struggle to get back on."

Cons: "It would have been great if a movie was provided."

Pros: "No one sitting next to me."
Cons: "I need more room."

Cons: "Didn't maker it to our destination."

Cons: "Boarding at Dulles was stupid. The line for 1st class and Premier was against the wall, so these passengers had to fight their way through the lines for passengers in sections 3,4,5 just to get to their line. It would make more sense to have groups 1 & 2 in lines which face the door, and keep the lines for 3,4,5 as they are--that is, parallel to the wall. Or, have the lines in the opposite order, so that 1&2 are closest to the concourse, and 5 is next to the wall I actually felt sorry for these 'privileged' passengers who had to fight their way through the other boarding lines just to board when their section was called"

Pros: "Quick easy trip"
Cons: "I couldn't put my Cary on luggage in cabin.."

Pros: "The crew went above and beyond on this flight. They were continously carrying around juice for us and constantly making sure we were all comfortable. The movies and TV shows were free if you had the united app.overall it was a amazing flight!"

Pros: "Everyone was so very helpful."

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

Pros: "Nice snack packs."
Cons: "Wow, chairs are packed really tightly front to back."

Cons: "You pay a price for an airline trip somewhere and then you have to pay again to get a seat on the plane. hard tiny seats, anything you want is extra money."

Pros: "Basically on time and no issues. Just a way to get from point A to point B"
Cons: "Seats not reclining. Not even a freakin free soda?"

Pros: "Well the flight itself was good overall. Seats were tight but i imagine all flights like that."
Cons: "Wellbi hated all the fees. For a checked bag, 35 dollars, to select your own seat 11-25 dollars, carry on 40 dollars, and nothing really special about the flight. Thought i was flying sheaper but i spent as much in bag fees as i did with the actual ticket price."

Cons: "We were supposed to depart in the early morning. One and one-half hours before departure (so at the time one should already be at the airport), we received a text and an email indicating the flight was delayed. The delay was 12 hours. The flight was delayed one more time, and we finally departed 14 hours later. I asked the customer service rep about the reason for the delay, and he replied "that's a funny story." The reason was because the airline was understaffed and the crew needed to rest for 10 hours. That is not a funny story. We lost an entire day of vacation. Frontier sent by email a voucher for a small amount to be applied towards a future flight. After this terrible experience, I am very very hesitant to fly this airline again. The crew on the plane was nice. There was no flight to Denver, by the time we finally departed, we were put on a direct flight to our destination. The direct flight was nice, but we still lost an entire day of vacation. We had to rearrange all reservations and add an extra night in a hotel. The voucher in no way makes up for the loss of vacation and the extra expense in changing reservations."

Pros: "Non stop flight."
Cons: "Paying for carry on bags-- 45$ Paying for any soda or food."

Pros: "Nothing"
Cons: "Arrived at the airport for a 5:45 AM flight and was told there was a four hour delay. Would have missed my connection in Denver to Seattle and instead of arriving in Seattle at 10 AM I would arrive there at 9 PM at night. I took a refund and went to Southwest where everyone was helpful and I was in Seattle by noon"

Pros: "They were on time & crew friendly."
Cons: "The charge for everything, even water, food, seats, carry on luggage."

Pros: "Flight time was good flight crew were nice and helpful"
Cons: "Delays were kind of annoying and the denver gate change was totally unexpected being i had to go to the frontier counter to have the associate print my ticket for me and had gate 36 for departure and flight left out of gate 40 ."

Cons: "We have several flight delays and ended up missing our connecting flight to our final destination. We sat in the airport for 9 hours."

Pros: "The affordability of the ticket"
Cons: "Checked baggage prices and how they are different online and at the check-in gate. They should be the same everywhere. The staff at the airport was rude."

Cons: "Very uncomfortable plane. Seats tiny and hard and did not recline. Paid $40 for a carry-on bag. Only water served without a charge for >2 hour flight."

Pros: "Not much"
Cons: "Seats are hard with almost no padding and don't recline, can't have a carry on. Tray table is too small to anything on! Front tier from my favorite airline to my least favorite airline in a matter of a few years!"

Cons: "Seats did not recline back. Very tight and uncomfortable but at least the ride was short."

Pros: "My husband uses a wheelchair, and the boarding and deplaning went smoothly. Crew was friendly and helpful. Flights were on time in both directions, in fact we got into Denver more than a half-hour early. Price was good. I'm sure you get a lot of complaints, but I'm glad you charge for carry-on bags. It encourages people to check items rather than trying to overstuff the overhead bins.."
Cons: "Not sure why I;m being asked to rate Food and Entertainment; there was none on the flights. We paid extra for more legroom, and the seats were still cramped. I don't think my husband could have even gotten into a regular seat from a wheelchair. Of course, this is not unique to Frontier."

Pros: "should have free coffee"
Cons: "no coffee"

Pros: "Ease if check in"
Cons: "Was unaware all food including coffee cost extra!!!! Seats are also very uncomfortable. They aren't what they used to be"

Pros: "thank goodness for isle seat"
Cons: "small leg room, seats didn't go back, really? not even coffee is free..."

Pros: "very smooth flight and excellent pilot and crew"
Cons: "I didn't get to pick my seat on this flight and had to sit in a middle seat."

Pros: "Service was good."
Cons: "I still didn't receive a $100 voucher that was promise because of the 10 hour flight delay."

Cons: "Original fight was cancelled and rescheduled for 6 hours earlier. Unable to do 6am flight and only other option was fly to Dallas first then the Denver. Long flight no food or entertainment."

Pros: "I liked the ticket prices."
Cons: "The seats were uncomfortable which made the entire flight uncomfortable."

Pros: "We were greeted and told, "We can get you to SLC until tomorrow", but that quickly changed to, "we can potentially book you on another airline". Within 30 minutes we were booked on a Delta flight that got us to SLC through Denver 30 minutes earlier than planned. We enjoyed beverages and snacks on Delta that would not have been provided by Frontier. The clerk at the Frontier ticketing counter was most helpful. We were able to make it to SLC and a wonderful vacation with family. We also received a voucher for $200 each. We will try Frontier again."
Cons: "Frontier did not have the appropriate redundancy to provide service for their passengers."

Pros: "Not much"
Cons: "Everything tha makes frontier itself."

Cons: "Having to pay for carry on bags"

Cons: "unconscionable fees, including baggage snacks and everything other than water. as long as your are at it whey not charge for water?"

Pros: "The trip was simple, quik & inexpensive."
Cons: "Seats were tight, snug"

Pros: "The crew"
Cons: "I've been flying frontier for years and it's sad to see the quality of their flights go down so drastically. The constant extra charges for everything, the major delays and the most recent recent redesign of the seats and tray tables just made for a very poor experience! I honestly do not want to fly frontier again."

Cons: "They lost everyone's luggage for over two hours and al they did was give us bag our baggage fee. I missed several appointments because of this."

Pros: "- Cheaper flight"
Cons: "-Aircraft was dirty, the windows hadn't been cleaned in who knows how long - There was a delay, but no communication, so we just sat there for an hour waiting in confusion - No complimentary drinks - Rude staff"

Pros: "The price was cheap. Boarding was easy. Pilots were very nice."
Cons: "No entertainment. Have to pay for everything even just water which makes no sense. Crew did not want to be there and was not helpful. Took forever for people to get off much slower than other flights."

Cons: "Seat are uncomfortable"

Cons: "They have hidden costs. The carry on charge is unbelievably high."

Cons: "They wouldn't even provide a cup of ice water for waiting over 4 hours delay. Then another 45 minutes before pulling away from the gate."

Pros: "Flight was on time."
Cons: "Seating is too tight."

Pros: "In the interest of always saying something positive, our check-in agents and flight attendants were friendly and positive both ways."
Cons: "-It cost an extra $17 if I wanted a seat on the plane -It cost an additional $35 if I wanted to bring any clothes -Flight to MKE was delayed over an hour -Flight back to DEN boarded on time and left a little early, however, upon arriving in DEN, there was no gate for us. We sat on the tarmac for about 20 minutes and actually ended up at the gate later than the scheduled arrival, so the early touchdown was pointless -It took almost 90 minutes for our luggage to be delivered to Baggage Claim"

Cons: "My bag that clearly fit as a carry on was held hostage at boarding until I paid $60!!!!"

Cons: "There was clearly an issue with the plane, and instead of being honest, we were continuously told it was paperwork and it'd only be "15 minutes." Plus, there wasn't even an effort to hold the plane from DEN to POR, although there were 8 of us needing that flight and we only missed it by a few minutes."

Pros: "Flight staff were very hospitable and kind. Plane was clean and seats were comfortable."
Cons: "They seemed to charge for everything. Even carry ons! $40/carry on! So much for packing light to save money and help the airlines with fuel savings. Checked bags are $30 carry ons were $40!!!! Crazy! Also, there was a charge for a beverage or snack onboard. Insane."

Pros: "Comfortable seat. Enough room to store my bags."
Cons: "The online check in to get boarding pass was extremely frustrating."

Pros: "Free seat upgrade at gate - Alex was very accommodating"
Cons: "Seats very uncomfortable, multiple delays for takeoff"

Pros: "Nothing"
Cons: "Canceled for no good reason. Never flying frontier ever again."

Pros: "Smooth flight"
Cons: "The seats were terribly uncomfortable!!! They had new thinner seats on my flight and you could feel little kids bumping or kicking your seat and every time they pulled down the little tray. The seats did not recline either. Very uncomfortable."

Pros: "nothing"
Cons: "Seats don't recline, they are hard as a rock, they are narrow and absolutely uncomfortable. Will never fly Frontier again and will recommend that no one else flys Frontier either."

Pros: "The flight was on time, smooth, friendly staff."
Cons: "You have to pay for a carry on, which is more than a checked bag, no complimentary food or beverage. There isn't much leg room, even for a short person as myself."

Cons: "Before my flight I went on the Frontier website to find the dimensions listed for an acceptable carry on in an effort to avoid checking a bag and paying luggage fees. I purchased said acceptably sized carry on bag only to find upon checking in for my flight that I would be charged $45! I was also informed that selecting my seat would bring a charge as well. The "great deal" I was led to believe I'd found by flying this airline was simply untrue. When all was said and done, I could have flown more comfortably and for less money on another airline. Will never choose Frontier again."

Pros: "It 's good and bad . For the good thing its fly on time. The bad thing its when the air plane going to lend it was too loud to made air hearts."

Cons: "I did not know you all do not provide complimentary beverages and snacks. I did not know I had to purchase a seat to sit in for check in and only one carry-on was allowed."

Cons: "It just sucks! Lost the bags for our flight and 3 other flights before than us"
