Pros: "Everyone was helpful and friendly."
Cons: "Not charge so much for luggage and carry-ons."
Pros: "The Crew"
Cons: "It was a passenger on the plane acting real suspicious. I didn’t like that. Also the seats was uncomfortable."
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$50 for a very small carry on luggage"
Pros: "THe passengers were well behave during and polite"
Cons: "The 2 hour flight delay"
Cons: "The crew was rude to the passengers. They charge form 9$ 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."
Cons: "Connecting flight was delayed by one hour!!!!!"
Pros: "Very fast boarding process."
Cons: "Seats didn't recline. The tray table was very tiny, dimensions were prob 5"x3" which barely fit my phone. You have to purchase drinks and snacks but they'll give you a cup of free water but only if you ask. On a 5 hour flight, no food or drink is very crappy so be sure to bring your own on."
Cons: "if flight was delayed should at least provide complementary soft drinks..."
Cons: "Delayed 7 hours"
Cons: "There was a malfunction online and I was overcharged for my flight. There were also delays going to and from my destination."
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!"
Cons: "The flight was first cancelled, then I had to wait two days for the next available flight out. Also was charged for my carry on bag. This airline does not offer any complimentary drinks. I will not book this company again, you think your saving a little and end up spending More at the end."
Pros: "Nice crew. Plane clean."
Cons: "On this long flight from Atlanta to San Francisco, a reclining seat would have been nice."
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: "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."
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."
Pros: "There was a 4 hour delay on both flights. What a HORRIBLE airline. They issued me a 100.00 voucher for a future trip, which I will NEVER use. I will not fly fron tier ever again."
Cons: "Everything. You have to pay for all luggage, drinks, everything. In the end, it is Not the cheapest because they charge for toilet paper. Oh get this, you cannot recline. That cost extra. Never fly FRONTIER."
Cons: "Operational failure by Frontier made the flight late and chaotic."
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: "My bag is still missing i don't have critical medication and I can't even get customer service to answer my calls"
Cons: "Flight attendant from Denver to San Francisco had a bad attitude and was passive aggressive with guests. Perhaps it was a long day for her but at the end of the day you have a job to do and don't take it out on paying customers."
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."
Cons: "Frontier charges for seat assignments and even carry-on bags. It's the #1 airline for indignities and nickel and diming its passengers."
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"
Cons: "We were stuck on the runway for over an hour after we landed and getting our luggage was a DISASTER. They changed the location of our baggage claim carousel with minimal notice, only to change it back to the original carousel with NO NOTICE. It took over an hour again for our luggage to come out and it trickled in so slowly, that I ended up getting my bag a full two and a half hours after we landed. Awful experience."
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: "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: "Crew were friendly"
Cons: "Airport gave wrong information, display showed gate A30 instead of the correct A11, mistake cannot just be attributed to airport but also to the airline for miscommunicating with the airport. Chairs were uncomfortable. But it was a cheap flight so understandable."
Cons: "Boarding was bad, after a delay it seem as if we were rushed onto the plane to make up time."
Cons: "45 bucks for ckecked bags and you have to pay for your carry on"
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: "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: "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: "When we got to the airport the kiosk was not working, and no one was at the counter. Checked in online, they charged us $45 per carry on (didn't read the small print, because it's so small, and no other airline I've been on charges for carry ons). To check a bag was cheaper, $35 but no one was at the counter. Also, they charged us $20 per seat when we checked in, did not give us the option of a no-charge seat online. (even though we did have tickets) So, I paid an additional $130 for the 2 tickets total. Shabby airline."
Cons: "Having to pay for a carry on. Having to pay for water on the plane!! That's insane! The fact that it's 2016 and there's no entertainment or free wifi. Ridiculous. I fly frontier out of desperation but never as a choice."
Pros: "N/A"
Cons: "the time , the plan is not on time and the customers service they are not patients ."
Pros: "$45 to carry on a bag and put in the overhead bin. Ticket was cheap but after paying $45 EACH WAY I spent more than buying a ticket on another airline that lets you carry on a bag for free. They even charge for soda. Ripoff. Will never fly this airline again. Buyer Beware. There is no way to know about the hidden fees before buying your ticket unless you want to spend an hour or more combing through the multiple pages of fine print."
