Pros: "Smooth flight. Early arrival. Friendly flight attendants."
Pros: "Nice new interior"
Cons: "Immediately after all passengers were boarded United discovered the plane had to be replaced. We all had to deplane, wait an hour more for a new A320, and reboard. Also irritating that delays are posted at 15 minute intervals and then updated; so you have to keep updating friends & family via WiFi. If it's predicted to be an hour, say so."

Pros: "The crew was very helpful and polite"
Cons: "Anything but water was for extra. We weren't even offered a small snack for the price of the flight. My flight was changed three times and it was very cramped.

Pros: "Everything was fine once I got on board the aircraft"
Cons: "Once again I had to see an agent to get a seat assignment on a 30 min layover. I though I got an upgraded seat but instead they gave me the wrong boarding pass. Same last name different first name so I had to wait till it got figured out and then be the last person to board so once again I couldn't find a place for my bag. Probably one of the worse flying experience I've had in a while"
Pros: "Overall very good. Friendly staff and timely arrival and departure"
Cons: "More leg room (on first flight) and drinks with ice!"
Pros: "Just happy to be home"
Cons: "That I asked to be put on an affiliate airline they didn't offer which was perfect because I was able to get home to get medical attention"

Cons: "I was left high and dry in Denver airport for over 12 hours because I was never notified of the change in connecting flight from AM to PM! I am absolutely livid. The Frontier agents weren't helpful at all in finding me an alternate flight. #wasteofmytime #NeverAgain"
Cons: "Late departure again! Poor everything! Frontier sucks!"
Cons: "The plane was cramped and uncomfortable. I also don’t like all the additional baggage fees tacked on to the original ticket price. I didn’t expect that when i first bought the tickets."
Cons: "Have passengers with no carry on off the plane first."
Cons: "too costly for baggage fees, seat assignments and beverage"
Pros: "Denver airport is really nice"
Cons: "Marginally better boarding than JAX"
Cons: "Everything. The staff kept lying about the fueling issue. They kept blaming the fuel tankers being frozen. They said 3 of them came, however i sat on the window seat and only one tanker came. After being delayed for 2 hrs and 15 minutes, when we got to cruise altitude they asked us for money for water. Are you serious? Also i was told that same plane will depart from Denver to Phoenix. I was told the same thing while in Chicago, during the flight to Denver and in Denver. It turns out everyone knew the flight left already from Denver to Phoenix. Needless to say, I won’t be flying with frontier ever again."
Cons: "Delay out...and delay upon arrival."
Pros: "Easy check in"
Pros: "We got there safely."
Cons: "They made the flight more than an hour late so that 12 people could make a connection. I understand having some compassion, but more than an hour? What about the rest of us who, do to the sardine can nature of plane travel these days, had to all listen to each other call their appointment s and explain the delay? Also, they charge for nearly everything -- soda, checked luggage ($45 for one!), carry on. I won't choose Frontier again unless it's my only choice."
Pros: "I was able to get from point a to point b with no issues"
Pros: "Didn't take flight"
Cons: "Don't overbook take care of customers. You have booked if you are late for flights you enter into contracts with them follow through"
Pros: "I lived"
Cons: "When I tried to get on at the last minute from Denver to Phoenix the girl at the desk right before I got on was acting like a jerk, other than that everything else was ok, definitely would be better if there was USB ports and if I'm gonna spend $7.99 on a shot of whiskey it would at least fill the glass up and the plane sounded like it needed repairs"
Cons: "I can't believe you have to pay $40 for carryon!!!"
Cons: "The seats were small and cramped. The flight was almost 40 minutes late due to delays in other flights. Our plane was there well before 955 but we didnt leave until after 1030 due to delays in other flights that had passengers for our flight on board."
Pros: "Crew was great"
Cons: "No food or drinks served Additional cost just to chose seats was crazy! Charging for a carry one...really? That is just madness and greed."
Pros: "The crew"
Cons: "Biggest regret buying this "discounted" ticket. Not a real discount. Found out there were a bunch of hidden fees when I was checking in. They charge $60 for the checked bag EACH WAY and was super shocked they charge for a CARRYON!! Unbelievable. None of the regular seats recline whatsoever unless you pay more hidden fees just to have your seat not be straight up the entire time, and there is no front table to put a computer. To save another dime, they installed some super cheap 6 inch x 3 inch mini ledges that they call tables. I'll NEVER fly with Frontier again. They also refused to let me check in early so I had to sit and wait for hours since they refused to give me a boarding pass until I came all the way back to ticketing exactly and only exactly at 2 hours before boarding. Worst flight. A total shame since the crew was incredibly nice."
Pros: "The cost of the flight"
Cons: "No complimentary beverages or snacks"
Pros: "Boarding was swift"

Pros: "The people around me who were miserable too"
Cons: "The seats were horrible , the cost of food and drink was outrageous"

Cons: "Lost luggage"
Pros: "The customer service agent st the desk was friendly."
Cons: "I arrived 90 minutes before boarding and missed cutoff for bag delivery because of poor flight time staggering and understaffing at the checkin desk. And now my flight is twice as expensive because of changing flight And bag fees. I'm very stressed by this experience and will never take this airline again if I can avoid it."
Pros: "That they waited for a plane to get in and take the passengers who were already booked. Between the holidays and bad weather, it was the right thing to do."
Cons: "A completely unprofessional,disorganized and disappointing experience. I will be sure to steer everyone away from this airline in the future"
Cons: "all of it."
Pros: "New planes. Plenty of leg room. Good customer service"
Cons: "The checked luggage came in two waves. The second took about 45 minutes."
Cons: "Was late going and coming back"
Pros: "Finally getting home"
Cons: "Employees were helpful"
Pros: "The boarding experience is terrible. The PA system and boarding announcements are poor, can barely be heard. On the video screen that lists the flight and (revised to an hour later) departure time, list the boarding zone(s) currently loading. It's a free-for-all among the passengers in the lobby jockeying for position to load."
Pros: "the price"
Cons: "We left Denver 50 min past our scheduled departure which made us late arriving in Phoenix."
Cons: "It was 20 min late."

Pros: "I was surprised with how smooth the boarding process was, how clean the plane was, and how nice the flight attendants were."
Cons: "Ground crew was not ready… 20 minute wait. Couldn't attach jetway… 25 minute wait. Baggage was delayed 45 minutes."
Cons: "Flight delayed"
Cons: "NO BAGGAGE & VERY LATE AT NIGHT"
Pros: "Boarding seemed to move really quick and seats were comfortable and seemed roomy."
Cons: "Flight was an hour late leaving. Check in at ticket counter was beyond packed, the line wrapped around."
Pros: "Crew very nice. Ticket and gate agents helpful, although a little stressed."
Cons: "Seating cramped and uncomfortable. Plane on this leg of my trip dirty - didn't want to place my purse under seat due to filthy carpet. Piece of window trim fell off during boarding; took 40 min to get maintenance to come up with roll of duct tape and make temp fix - flight delayed more than 1 hr overall."
Cons: "Again I paid for emergency exit seats and people moved into those seats from other Rows after the plane was boarded that did not pay for those seats I feel ripped off"
