Cons: "Space a little tight but my flight was only 2 hours so I could live with that. Would love option of an entrainment unit on seat backs but I understand that with cheap flights it wouldn’t be cost effective for frontier. Flight delayed but that happens a lot with other airlines. Gave regular updates at desk and reason for the delay. Staff wonderful. Plane spotless"
Pros: "Nothing very disappointed with Frontiers service"

Cons: "Nothing"
Cons: "We arrived very late due to the airline being run so poorly. Something about paperwork according to the pilot. Now the rental car company is closed so I have to sleep at the airport and wait till the budget opens again in the morning. Frontier should put me up in a hotel as their mismanagement caused the delay not the weather. But they just said too bad because the flight was less than 4hours late. Frontier - never again!!!- plus the seats are painful"
Pros: "a bit better, the flight was only half full so it made the experience more enjoyable overall."
Cons: "Kinda annoying they are always trying to upsell."
Pros: "Nothing was 2 hrs late"
Cons: "Was 2 hrs late"
Pros: "Attendants very personable, boarding very efficient"
Cons: "Seats were uncomfortable. And because I purchased a cheaper ticket I felt everything was a la carte and very expensive."
Pros: "The flight itself was fine"
Cons: "I used to love frontier but now everything from baggage policies to checking in feel like a huge hassle"
Pros: "Crew took great care of passengers as we were delayed 2 hours on the tarmac for deicing. Not their fault but the company gave passengers a $50 certificate for our late arrival."
Pros: "The fair was low and boarding was efficient."
Cons: "The booking process was terrible online. There’s a charge for refreshments, the tray table is tiny, the staff didn’t seem happy, the seats don’t recline at all, they charge for carry ons, no outlet to charge my device."
Pros: "crew"
Cons: "you should be arrested for those seats"
Pros: "Comfort seating is spacious."
Cons: "Doesn’t make sense to charge for water."
Pros: "When we were flying from phili to Charlotte they put my boyfriend's bag in the slot to see if we woyld have to pay for our carry on. His was good. Mine was a little bigger but because i had my chemo medication in it they did not charge me. When i was returning from Charlotte they charged us for both bags. I told her they didn't in phili and she said every airline does it. So maybe something should be written in ur policy. What is the sence of taking a carry on when you are going to pay $90.00 round trip. Makes no sence to me. I hope u do reply back. Other than that everything was good."
Cons: "Read the above . and now i c the reviews and everyone had the same problem. Getting charged!!!"
Pros: "I got there safely."
Cons: "The crew did not help people with bags and barked when people opened doors that were closed. There was no entertainment and no complimentary snacks or even water."
Pros: "Staff was Friendly and The Price was Great"
Cons: "There wasn't anything"
Cons: "Poor customer service. Baggage fees are ridiculous. Checking in online or by app and paying for bags doesnt save any time. You still have to wait at the counter in the airport. No bag drop. Airplane seats are uncomfortable. Waited on the tarmac for about 45 min"
Cons: "Seats were very uncomfortable they didn't even recline on top of they charge you for every single thing."
Pros: "They were friendly and assisting. Boarding was smooth."
Cons: "Super uncomfortable after 3 hours"
Pros: "Nothing."
Cons: "Had an issue with flight attendant humiliating me in front of all passengers around me."
Pros: "It is so convenient and was a pleasure to get in and out. Pick up was a little crazy but still nicer than other airports."
Pros: "We sat on the plane for two hours before having to get off. The plane was scheduled to leave at 11:59 pm and did not leave until approximately 7:00 am! Pitiful. I will never schedule another flight on Frontier."
Pros: "Nothing"
Cons: "Flight was cancelled. I was not notified until after I arrived at the airport. The only alternative they provided was flying to my destination 5 days later. Their phone line has a 2 hour wait so I am still waiting to find out if I have a refund for my flight. Not worth the cheap flight."
Pros: "Nothing."
Cons: "Flight was cancelled and I was told my only option was to wait 5 days or take my money back. Frontier refused to help me get on another airline to get to my destination. So I end up with a $150 refund and a last minute flight that costs me $600. Terrible customer service. Any other airline would've put me on another flight. never using Frontier again!!"
Cons: "Seat selection charge? 12$ carry on bage charge 45? And not even a bottle of water for free! I will avoid this airline if possible, I like to know how much the trip will cost in advance. For a round trip flight it was an extra 24$ for seat selection and 90$ for a carry on bag! That's 114$ that I could not avoid and would not been able to get on plane until paid ! No information about these charges appeared anywhere while purchasing the ticket!"
Pros: "Friendly crew. Alot of empty seats so we could stretch out.."
Cons: "I don't know why they bought a plane with seats that don't recline and tray tables are only half as wide as normal."
Pros: "The flight was on time."
Cons: "So cramped. So uncomfortable. The crew didn't seem to want to be there any more than we did. I know it's a budget airline, but pleeeease put a little give in those seats."
Pros: "I had no problems. Our flight arrived early."
Cons: "Too many advertisements/promotions over the PA."
Cons: "Frontier didn't have the correct gate on the boarding pass and usually isn't even in the display boards. It was fine for me but anyone not airport savvy would be upset."
Pros: "I never write reviews, but I have to say something about this wonderful flight crew. I have a serious fear of flying and their great attitude and funny personalities made my experience 100x better than usual. Please send them my thanks!"
Pros: "Nothing!"
Cons: "We booked this flight well in advance and had confirmation for it. Imagine our dismay when we received a notification a few days before our trip that our connecting flight from Denver to Salt Lake City was changed to 10 hours later. When we arrived in Denver, we went to the customer service desk and was told that the flight we had booked didn't have any seats for us and we would have to take the later flight. No explanation. It was scheduled to leave on time, just that they had no room for us even though we had a confirmation number for that flight. I don't know if the responsibility was with Frontier airlines or our booking agency, but rest assured I will not use either one of them again."
Pros: "Nothing"
Cons: "The plane was delayed and I was not notified by email."
Pros: "The crew were great and my flight was on time"
Cons: "Charged $40 for carry on bags! Also no complimentary beverages or snacks at all"
Pros: "They let parents with children under 3 board first along with those that need help. That was a plus for me since I was traveling with my 2 years old grandson"
Cons: "I had no complaints"
Pros: "Hey just a normal flight like the rest except I saved over a hundred dollars and it was a direct flight."
Cons: "I'm sorry I usually do not say anything negative but all 4 of my flights were bad. They were all late. 2 out of 4 were at the wrong gates. There were no announcements made. If I had not looked myself I would have not even knew.. The crew were rude and unfriendly. No one smiled. Over all a very unpleasant time. I will not use Frontier airlines again."
Pros: "YEAH FRONTIER! They did a fabulous job getting me back home and once again on time and without any problems! Staffs were kind and gracious from the ticket counter all the way through! LOVE this airline! Watch out Southwest!"
Cons: "Frontier has a lot of hidden fees such as having to pay to have a carry on bag and also trying to charge me for a seat when checking in online. I mean, what exactly did I pay for when I purchased my tickets? Ridiculous."
Pros: "- The quick check-in was great, I found that it was maybe one of the easiest I've had. The flight was great for the cost as well, I was happy to know that it was just what I needed."
Cons: "I didn't like that they didn't offer any snacks on the fight, not even a water or pretzels, everything costed money."
Pros: "Smooth flight, on time departure."
Cons: "Paying extra for everything; eg. seats that were no better than any others, with arm rests that were like rocks; paying for coffee. The 'threat' that if yiu din't pay for seats tigether, you may be separated frim your companion. Overall, a great example of overpromising, overcharging, and underdelivering. A flight attendant whose response to my surprise at having to pay for coffee was "...I don't make the rules." Frontier should spend some coffee money on retraining attendants on customer service."
Pros: "The price"
Cons: "Everything else. Terrible seats, most uncomfortable flight ever. No complimentary beverage/snack."
Cons: "-$40 fee for carry-ons (I am a violinist, so my violin is my carry-on, meaning I also need to bring a checked bag) -$35 fee for checked bags -non-reclinable thin plastic seats -everything on board costs money, including water -both my flight to Charlotte and back to Chicago were both delayed for the same stated reason of the airline not allocating enough time for the plane to be released from inspections after a previous international flight -no information about new projected arrival times -poor communication with waiting passengers -loud thumping and beeping noises on the plane"
Pros: "Boarding was efficient, staff friendly and helpful"
Cons: "New rigid seats uncomfortable in every way, could not feel more packed in nd I consider myself average size at 5'9" 160lbs. I am used to paying for premium seats, and now even used to paying for seat selection at all, but Payment for Carry on policy is a new low in customer service offered."
