Pros: "The crew was very attentive to each guest."
Cons: "Well I paid more for a lesser quality plane ride... didn’t like that very much."
Pros: "The crew was very friendly."
Cons: "Flight was late, excessive baggage fees, plane was dirty, there was trash under the seats in front of us."
Pros: "When the bag size is small , boarding pas would not print without paying the $50, u would like to get refund"
Cons: "Most of the other do- passengers k we the rules of the airlines while I was unaware of the rule bad ended up paying$50 for a very small carry on luggage"
Pros: "Was direct and easy. No issues with boarding or flight"
Cons: "Cramped"
Pros: "Nothing"
Cons: "I will never fly Frontier airlines again. No matter how inexpensive the tickets are, it is not worth the aggravation. Agents were rude. Flight horribly delayed. Plan ride was uncomfortable. I lost my car rental because they close at 5:30pm. When there own employees say there flights are always delayed that alone said it all."
Pros: "THe passengers were well behave during and polite"
Cons: "The 2 hour flight delay"
Cons: "The crew was rude to the passengers. They charge form 9$ to 40$ for seat selection. Charge for a Carry on bag (anything that doesn't fit under your seat). The flights had maintenance issue, hence delayed. I will absolutely avoid traveling with frontier in the future."
Pros: "Nice new clean plane"
Cons: "Connecting flight was delayed by one hour!!!!!"
Pros: "I arrived safely. The crew was very friendly and helped to. All my husband who was scared as this was his first time flying."
Cons: "The agent who checked me in was extremely unprofessional. I felt like she was envious that I was going on a vacation and she had to work. She tried to make my experience a living hell. I personally think she should be fired. She does not enjoy what she is doing. She joyfully told me that it costs $40 to carry my luggage and after I informed her that I saw it online for less she informed me that I should have bought it online. She then stuck me all the way in the last row of the plane. I am 5'9". My husband is 6'2" and over 300 pounds. Those seats have the least leg room. It was pure torture. The flight crew in the back help my poor husband by using humor to help him."
Cons: "Uncomfortable seats - don't recline! Rude crew, create an impression if they're doing you a favor by being there. Flight significantly delayed. No clear announcements. As a frequent flier, didn't expect a Spirit like experience from Frontier!"
Pros: "Nothing."
Cons: "After paying for the flight. We had to pay to get seats guaranteed next to each other. And the charges for everything including a ridiculous amount for a can or soda or water and a snack."
Cons: "There was a malfunction online and I was overcharged for my flight. There were also delays going to and from my destination."
Cons: "The seats couldn't recline plus they were very uncomfortable to be in."
Pros: "This was my first time flying Frontier, and I was pleasantly surprised with how smoothly everything went! Check in was simple, the flight was on time, the cabin was spacious and we arrived almost an hour ahead of schedule! I will definitely be flying with Frontier again!"
Cons: "I was charged $10 extra to check a bag because I didn't pay in advance. This was my first time flying with Frontier, so I was unaware of this."
Pros: "The crew was friendly and helpful."
Cons: "There were extra fees for carry on and checked bags, which was not revealed until we printed our boarding passes. In addition, we had to pay to reserve seats. On top of that, I have never sat in such uncomfortable seats. They charged $2.99 for a can of soda on the flight. Finally, they lost our bag, after our flight took an hour longer than it was supposed to."
Cons: "5 hours late, no updates sent via text or email, $15 dinner boucher useless and given after restaurants closed. I will never fly frontier airlines again!"
Pros: "Nice crew. Plane clean."
Cons: "On this long flight from Atlanta to San Francisco, a reclining seat would have been nice."
Pros: "The seats were comfortable and the thin profile gave a feeling of roominess."
Cons: "Baggage fees and carry of fees. You can save by paying online but I didn't learn that until the second time around."
Pros: "The initial price I paid. Which was very reasonable for a non-stop flight."
Cons: "Paying for a checked bag. Paying for a seat so I could be assured a decent seat. My decent price soon became what I would pay on any major airline. So why would I fly Frontier?"
Pros: "The crew was friendly and helpful."
Cons: "Had to sit on the tarmac about 30 minutes on arrival in Indianapolis because another aircraft was at our gate. Why couldn't we have gone to a different gate? Arrival was at about 9pm and the airport wan't that busy. This was uncomfortable. Would have been a good time to hand out free snacks and beverages or drink coupons for a future flight."
Pros: "Little."
Cons: "Worst flight of my entire life."
Pros: "Boarding. Charging for baggage limits what passengers can carry making boarding and sitting quicker"
Cons: "oK with me to buy my own snack and pop. Can see that it may catch people by surprise as passengers not notified earlier that except for water have to purchase own snack."
Pros: "I flew from Seattle to Denver. It was okay."
Cons: "When I flew from Denver to Philadelphia, the assent was excruciatingly painful for my ears. I thought my eardrums were bursting."
Cons: "Flight was significantly delayed. Advertised as low cost, which it was, but that is because they make you pay for everything except water. Seats do not recline either...bad for red-eye."
Pros: "Nothing."
Cons: "The flight was delayed for over 4 hours due to operational issues (not weather or maintenance). The gate representative didn't keep us informed of the issues and when he did, he was usually wrong. There is a surcharge for everything from carry-on fees to beverages on the plane. The plane itself was uncomfortable with uncushioned seats. Let's just say that if I had to choose between a Frontier flight and a Delta flight that was $400 more, I will choose the Delta. Same goes with any competitor. I will never fly Frontier again."
Cons: "It's very late to get a hotel and they didn't arrange anything for us. We get a credit for future flights and hotel reimbursement. But I'd rather not fly Frontier again!"
Pros: "Low price was great. It had everything I needed which was a flight to where I wanted to go. It didn't have any additional amenities but the lower price was worth it."
Cons: "You get what you pay for. No entertainment. No complimentary drinks or snacks. A fee for a carry on bag. All of these however are unnecessary so it was fine."
Cons: "Flight From San Antonio to Philadephia, Late for 1 hours Flight from Philadelphia to San Antonio boarding on time, however we have to wait for 1 hour to take off"
Pros: "Did have good leg room in exit row."
Cons: "Thought we got such a good deal on flight, but had to pay extra for carry-on and even to choose a seat. The seats did not recline, but maybe that was because we were in exit row. Boarded an hour late to clean up from last fight because of (per their announcement) vomit."
Pros: "The crew and neatness"
Cons: "Entertainment"
Pros: "I do not normally complain, but my two flights this weekend were more than an hour late each, coupled with horrible cramped seating, unfriendly flight crew, tons of extra charges, and a dirty plane. I will be trying to avoid frontier flights on the future."
Cons: "See above."
Cons: "Flight had uncomfortable Seats was delayed 1.5 hours and the baggage took more than 30 mins to come out"
Pros: "Nothing."
Cons: "Got a cheap flight but little did I know that that would be offset by being nickeled and dimed for seats, bags, and drinks. On top of that th plane was five hours late from its start point and the only information the gate agents would give (with an attitude) was the plane was coming. I called customer service to see if they were offering any restitution for this, and I was told that's not up to him. I will never never never fly frontier ever again."
Cons: "A word of caution to anyone flying Frontier airlines. Carry on bags cost $40 each way. Even checked baggage is cheaper at $35. Don't forget to add the extra $70-80 when you see the tickets slightly cheaper online. Plus, it will cost more to select seats to sit together and even the snacks/drinks cost money. I'm shocked I didn't have to pay extra for a pilot."
Cons: "I was seated between an overweight man and a very tall man, both of whom felt as though their sizes allowed them to infringe upon my space. There were plenty of open seats on the flight and yet no effort was made to alleviate this clear problem."
Pros: "The time of the flights, and the quick security at the terminal."
Cons: "Hidden fees for everything. You book your flight for one price. (mine was about 100$ less than other airlines at time of booking) -Then they have you pick your seat (charge) -Then if you want to check a bag (charge) -Then if you want to BRING A CARRY ON (CHARGE) It ended up being way MORE than the other flights I could have just booked on other airlines. (I booked at $220.00 and by the end of my trip spent $373.00 with Frontier) Also, the returning flight was delayed 45 minutes but I received no notifications."
Pros: "The cost was low, so it made the return part of my trip easier to pay for."
Cons: "I had not been prepared for how "no frills' your airline is, so I didn't know to expect rigid chairs with no adjustment, and that all items offered in flight were to be paid for. It wasn't a long flight, so I didn't miss not have a snack or drink, but I didn't know any of that in advance. My fault for not checking into it a little more, but it was a whirlwind trip to move my daughter and the travel was Spartan but necessary."
Pros: "The flight was right on time leaving and arrived early. The planes are new ."
Cons: "the boarding pass was wrong. The check in clerk forgot to tag my bag with the any tag.so it stayed in Phila. They did deliver it on Wednesday to my house. Thank you."
Pros: "Nothing"
Cons: "Seats hard plastic and inhumanly closed together. Tray tables smaller than a car's sunvisor. I think Frontier should be called the Middle Passage airlines for how they pack us in. They make you pay for luggage, improved seat size, location, food and then ask you to tip your cranky flight attendant whom they seem to screen and select the most misanthropic applicants they can find. And then they try to sell you their credit card with a $69 annual fee. I watched and there where no takers."
Pros: "Seats were comfortable and I arrived safely. Grateful for these aspects of my trip."
Cons: "Employees were rude. Inaccurate information about flight times provided before and during the flight. The hidden fees were ridiculous, such as $1.99 for seltzer water. Note that you cannot pay in cash for anything. Not so unusual, but a pain for since my debit card was lost. Because flight times were inaccurate, I had no time to buy food during my layover and wasn't able to purchase food on the flight. Overall, I would NOT choose to fly Frontier Airlines again unless absolutely necessary."
Pros: "Your flight's delay was unchanged; I likes its consistency."
Cons: "I did not like paying $5 more for my checked bag. Although I did log in to see if I could check in more than 24 hours before the flight nothing suggested that I should pay for my bag though I could not do seat assignment at that time. I did not like that I paid $5 for set assignments inferior to what my friends got by taking their chances. Although I understand your motives, not showing what the free alternative is seems a bit smarmy. The one hour delay on the tarmac before we could get to a departure gate was not directly your fault, but it was annoying."
Pros: "The staff"
Cons: "The plane, the five-hour delay."
Cons: "Boarding was bad, after a delay it seem as if we were rushed onto the plane to make up time."
Pros: "Nothing"
Cons: "These flights are horrible- hard cramped seats, no services, not even a cup of coffee unless you pay extra. $40 to bring a carry on bag on the plane. Cost more than any other flight in the long run."
Pros: "Boarding process was easy Crew were attentive On time I didn't pay for a seat, but got an aisle anyway"
Cons: "Checked bag and seat fees Seats do not recline Charge for water! Tray tables are half the size of typical trays, but I guess since they don't feed people, it's not much of a problem"
Pros: "Flight left and arrived on time."
Cons: "Seats didn't recline and website is misleading when it comes to purchasing seats. I was very uncomfortable."
Cons: "Getting nickeled and dimed for everything from carry-ons to seats to drinks. Uncomfortable seats"
Cons: "I didn't like how we were notified last minute about our flight being delayed for THREE hours. There was no voucher offered as well. Completely terrible."
Pros: "Smooth flight, courteous staff and on time."
Cons: "Be sure to get there definitely two hours prior due to their strict policy about boarding. It would be nice to offer something for their flight, snack, etc. At least water."
