    Will recommend everyone if it's urgent work please don't travel with this airline. Always late and have lot of issues. Don't travel with kids and old people. Because they don't have any rules and regulations. African airlines is better than this.

    Flying with frontier from Houston to San Francisco through Las Vegas was an absolutely miserable experience. The issues encountered were myriad: The flight out from Houston to LAS was over 2 hours late. During that time, the air conditioning was not functioning properly - so a full flight of passengers sitting in over 90 degree heat during an excessive heat warning for > 2 hours.

    As this delay would make me miss my connection, I tried reaching out to have my flight from LAS to SFO rebooked - initially through the app. However, a bug in the app meant at some point I could no longer type any replies, and trying to refresh the page lost me the connection with the agent. I then tried to access customer service through Whatsapp, but the link from the app didn't work. Instead, I had to Google search it and initiate a Whatsapp conversation from there. The service staff I got connected to was helpful, but quite slow (>2 minutes for any reply), but luckily/unluckily the flight was delayed long enough to have her complete the change for me.

    As the missed flight caused an overnight stay of >12 hours to the soonest next flight, I requested hotel vouchers later after landing but the new customer service agent I got connected to could only offer "<name>, as much as I'd want to, hotel vouchers are only distributed by the airport when they are available. Please contact them if you are still at the airport." As I was exhausted, I was already out of the airport by this point and on my way to a hotel I booked on my own dime.

    I did however try to speak the next morning to Frontier staff at the airport to inquire of this, which was the worst bit of the experience. The manager at the station was extremely rude and did absolutely nothing to help. She showed no empathy to the situation, refused to engage even when presented with the above text from customer service on the hotel voucher and needing to talk to ground staff about it (her response was a repeated "contact customer service, we can't offer that here, sir you're not listening to me" even when I showed her literally what customer service said when I contacted them) and only offered to offer a meal voucher if she could confirm the cause of the flight delay.

    This involved having me stand to the side by the counters for over 20 minutes, at the end of which she told me to go to the gate and speak to the staff there. Her game plan was clearly stonewalling me till I gave up. This pattern of no one on the staff taking any ownership, stonewalling on customer concerns, and deflecting by trying to foist any dissatisfied customer onto someone else so it becomes their problem is laughably terrible, and means you've gained yet another "Never Fly Frontier" data point.

    Your airline is literally terrible, process is janky! Hot on the plane, always delayed and unprofessional. Y'all should really close this airline, the customers would be better without your airline lies of on time flight departure. Customers pay money for on time departure and arrival not to fill your effing pockets.

    Don’t let the cheap fares tempt you for any flights with connections. Because the planes were stuck on the tarmac I missed my connections twice on the same trip, coming and going. In both cases the agents on the ground were not helpful, only offering the next flight which was on the next day. They did not compensate or help with hotels. Basically you were on your own. The app was inaccurate or did not have any info.

    Frontier Airlines failed to get me to my destination 2 times in a row costing me thousands to rebook with another airline, please don't fly with them. Their customer service has not offered anything to compensate for incurred cost or time except a measly $100 flight credit. This time our group of 4 was flying from Salt Lake City to Cancun with a layover in Denver, I got to the airport and there was no gate agent, we checked and found out our flight was delayed which would cause us to miss our connection, Frontier had no other option to get us from our connection to Cancun for a couple days so we had to rebook through Delta Airlines at a cost of over $5,000 plus additional rental car and hotel costs due to their schedule being a day later on both ends of the trip.

    Family members had a flight on Friday, May 30th that was delayed 3 times from New Orleans to Pittsburgh, with a connection in Orlando. Their bags have never arrived and after hours on the phone with numerous employees, nobody can find them. Customer service is the worst experience of any situation we've ever had. 8 to 10 hours a day trying to track the bags has accomplished nothing. No one can say for sure where the bags are. Service numbers have had 2 to 4 hours of waiting time, (No surprise). They have to resort to physically track down their bags by driving to the original destination of their flight. Service desk at the airports are only open when flights are arriving and departing. What a joke of an organization that treats its customers in this way. Buyer,s be very aware that they have no clue how to treat their clients.

    If I could give this airline a zero I would. Don’t be sucked in by their low fare or if it’s a nonstop flight. This is absolutely the worst airline I have ever flown. From customer service to rude employees to such disorganization, I can go on and on. I will never fly with them again! I would rather pay extra money than to go through what I experience with them. Also, by far the worst group of individuals at the Cleveland airport. There are way too many other airlines to fly, Frontier is a total fail in every aspect. Save yourself the frustration and fly with another airline!!

    I have never heard that you needed to be at the airport 3 hours before a flight for National travel. When checking in yesterday, it said 1 hour before. I got to the airport at 4:45 am for a 6 am flight and I was told by the agent at the beginning of the line that the flight was closed because I was supposed to have been there 3 hours prior. I asked to talk to someone and he allowed me to make the line. Obviously when I got to the counter it was 5:08 am and the lady told me that I was late and gave me the same explanation (that I needed to be there 3 hours prior), and that is had lost the flight without even allowing me to ask any other questions or offering a solution. I lost the flight, the conference I was going to and 1 night hotel on Denver. This is the worse experience I have had in all the years traveling and using many different airlines. Frontier is by far the WORST!!!

    Frontier Airlines! I’m a United, JetBlue, Delta and American Airlines customer. My daughter went to Puerto Rico last week and her friends booked with Frontier. She was supposed to fly back yesterday, 5/31/25 at 12:42 pm. Flight took off but returned about half hour later. Which is fine, but take care of your customer!!! It was rescheduled for 1:00 am 6/1. They changed it again to 4:00ish. My daughter and friend are waiting at airport with a $27 voucher for food. Decent food is expensive and $27 wasn’t enough. They all boarded at 4:00 am ish and had to exit plane for whatever reason. The flight was cancelled. They got their luggage and wasn’t properly informed of the situation. The workers are rude and offering NO information. They are now set to board at 9:00 am, 6/1/25. Almost 24 hours at the airport. This is ridiculous!

    Unacceptable experience on flight 4964 from Los Angeles to Dallas, Texas, scheduled for May 23, 2025, at 7:05 PM. The flight was delayed eight times (to 7:46 PM, 8:46 PM, 9:36 PM, 9:55 PM, 10:25 PM, 10:50 PM, May 24 at 10:00 AM, and 11:15 AM), forcing my family, including my one-year-old, to spend over 15 hours overnight at the airport.

    Frontier staff denied us hotel vouchers due to our California residency, and with our luggage on the plane, we had no blankets or sweaters, leaving us in cold, uncomfortable conditions. My one-year-old was distressed, and my daughters were emotionally and physically exhausted, now refusing to fly with Frontier.

    My luggage, valued at $3,000 (including shoes, clothing, a breastfeeding pump, a $300 hair straightener, and four $150 colognes), remains unrecovered. The delays caused me to miss my son’s soccer tournament, a $400 Airbnb night, and a family member’s car loan, leading to a $600 car rental. I also spent $150 on transportation to the airport and $500 on replacement items, food, and essentials. Unacceptable, worst experience ever.

    CANCELLED MY FLIGHT AND LEFT ME STRANDED!!!! ON 5/26 Monday - My flight was cancelled at 4:30am - 1 1/2 hours before my flight was supposed to take off out of SFO. When I got to the ticket counter - the lady told myself and everyone else that the next flight out of SFO for Frontier was Thursday - 4 days away. There was no explanation as to why our flight was cancelled and no way to get home. Over 100 people just stranded in SFO!!! We were all scrambling to find our way home. I was able to get on another flight after buying a one-way ticket at the cost of $450.00 which was the cheapest and closest time to my original departing time. I was trying to get home as quick as possible to my sick child.

    Calling Frontier the next day - all they said they could offer me was a refund for the part of my flight that was cancelled and $100 flight voucher that had to be used in the next 90 days. Like I was going to fly Frontier again and be left in the same situation. I am a single mom, I could NOT afford the one way ticket but I also had to get home asap. Looking at the company website and Barry Biffle - the CEO of Frontier; he is worth millions and makes millions a year but their revenue has continued to go do substantially for the last several years. Considering this situation - it probably has happened more and more times and why they are losing business. I will never fly Frontier again considering their customers are not valued and they do not do anything to help when they leave them stranded at the airport after they cancel the flight for no reason. Seriously poor Customer Service for a multi-billion dollar company.

They wouldn’t let us off the plane and when we got to Denver they said they would refund only the half of this flight and there was nothing they would do to help, after enough complaining we finally got a flight the next day to Spokane where we would have to rent a car to drive the additional 6 hours to Portland and when we got there they lost all of our luggage and said they don’t know where it would be at. And now no one can explain where our luggage is. They won’t refund any part of this trip, or do anything about all three bags and all of our belongings stuff.

    Frustrating Customer Service Experience.** I recently had to contact Frontier Airlines after a travel issue and was appalled by their lack of support. I spent ** over 40 minutes on hold** with their customer service line, only to be disconnected twice. Their text/chat system was equally unresponsive—it repeatedly claimed agents were "available to chat" but never connected me to anyone.

    This complete lack of timely assistance left me stranded without answers during a time-sensitive problem. While Frontier’s fares might be budget-friendly, their customer service is *anything but reliable*. I’ve flown with other low-cost carriers (like Southwest or Spirit) that prioritize communication—Frontier needs to overhaul its support systems to match. Save yourself the stress and book elsewhere if you value timely help.

    We were supposed to fly out from Atlanta to San Juan at 4pm Sunday, May 4th. We were around 40 min late getting to board the plane. We sat on the tarmac an hour or so before our plane started moving around the runway. We were told there was a brake sensor issue. We wound up sitting 5, FIVE!!!, hours on the runway before being told our captain was over his flight hours and we had to get off the plane. A notification came to the APP saying the flight was delayed until the next day at 9am. No one from Frontier knew anything, or would tell us anything. The line for customer service was half a mile long. Why didn’t Frontier announce to all the passengers about what to expect? Were we getting our luggage? Were we supposed to do anything to be on the 9am flight the next day?

    We wound up trying to find 2 hotel rooms at 11:30 pm with no luggage (our checked bags were not returned). We had not eaten since a snack at lunch. We received no compensation, other than $50 voucher for the “next flight”. AS IF!!!! Everything other than the air you breathe was an add on. Nickel and dimed to death. Tickets booked together as a couple are deliberately put on opposite sides of the plane to try and get you to pay $30 per person, per flight, to sit together. And while we waited 5 hours in cramped seats, we were given a cup of water and a cookie for free. So generous of Frontier. I will never fly with this airline again.

    Well, let's start with the good. The plane looked very clean. The flight was on-time and I arrived at my destination. To some that should be enough. First complaint is regarding the seats. HOLY CRAP - they are torture devices designed by an accountant. HARD, no padding whatsoever - I'm talking park bench level here. Then there is the room itself. I get it, they are trying to squeeze everyone in - this is the ABSOLUTE limit - anything over two hours consider getting off and going to a back doctor.

    My problem with this particular flight was the flight crew. Having worked as a flight attendant myself I can honestly say they were nothing short of horrific. It was the first airline I've ever got on where the flight attendants were on their cell phones and didn't bother to acknowledge my existence. Not that I need that - but this is their job. Greet people make it cheery - smile. They all looked like they had been run through the ringer. Not one of them smiled - I attribute it to the feeling of an old Soviet era flight. Again, I got to my destination - San Diego, but imagine my surprise when I got off the plane in Las Vegas and had to get BACK on with the same nasty crew. Seriously these people were NASTY, the seats suck, the room is barely passable. I get low-cost - but this is one that needs improvement in the worst kind of way.

    If you want to fly fairly inexpensively - do not - look to Frontier. The unassigned site will be cheap but if you want to select a seat the upgrade cost is very expensive. The checked bag fee is expensive and you must also pay for carry-on bags!! They will also make you pay for snacks and any kind of drink on the flight. There is no WIFI or phone jacks on the plane so be prepared. My baggage was very damaged during both flights, we were making jokes that there was a T-Rex trying to bang its way out of the cargo hold.

    On May 17, 2025, at approximately 1:45 PM, my fiancé Ikia and I had a frustrating and disappointing experience at the front desk while preparing to board Frontier Airlines Flight F9 2634. We were met with unhelpful and inaccurate service from two customer service agents, Ms. Katelyn and Alexis. When we asked if we could be accommodated with seats together, since our original booking had us sitting separately, we were incorrectly informed that we had not paid for seats and, even more concerning, that we did not have seats on the plane at all.

    This response was both confusing and distressing, as we had valid tickets and expected at least a baseline level of clarity and professionalism. It was only after we requested to speak with a supervisor that the situation began to improve. Thankfully, Mr. Jaylen stepped in and handled the matter with professionalism and care. While we were ultimately still seated apart, he confirmed that we did indeed have seats on the flight and ensured we could travel home as scheduled. We’re very thankful for his calm demeanor and solution oriented approach, which stood in stark contrast to the dismissive and inaccurate service we initially received.

    Frontier Airlines must address the training and oversight of its ground staff, particularly agents like Katelyn and Alexis. Providing passengers with false information and failing to show basic respect or courtesy is unacceptable. While we appreciate the support we eventually received from Mr. Jaylen, this incident highlights the need for better training and accountability in customer service to ensure other travelers don’t experience similar issues in the future.

    Flight F9-1068, originally scheduled to depart on May 2, 2025. I and many other passengers boarded the plane and remained seated for approximately 2 hours and 30 minutes before we were instructed to deplane. At that point, we were informed the flight was delayed until 9:30 a.m. on May 3, 2025, which was subsequently delayed to 11:45 a.m., and then again until 1:00 p.m., when we finally departed. Adding insult to injury, Frontier Airlines has denied providing any refund or travel credit, citing that passengers had “boarded the plane” and therefore the initial delay does not qualify under your policy. This rationale is extremely disappointing and feels like a manipulation of technicalities to avoid compensating passengers for a major inconvenience. It is especially frustrating given the total delay extended well beyond 12 hours from the original scheduled departure.

    I too dealt with "Joshua" on the chat line (see review above). I claimed a $525.98 refund for an additional ticket for two PHL-TPA. The second tickets were necessary because of fraudulent statements of Gate Agent enforcing a bogus two-hour cut-off for passenger arrival (See review Below). "Joshua" can be reached only through Frontier's chat line. He apologized for the gate agent and proceeded to see what he could do. He consulted his records. Suddenly he said that I had received a refund of the fare I paid in cash (about $ 230) for the first tickets and the ff miles I used were forfeited. He pronounced this was a "full refund" (how so?) and abruptly hung up before I could object. Obviously, this "full refund" does not make me whole. His pronouncement was in bad faith.

    Importantly, his hang-up wiped out my record of the chat including his apology! If Frontier allows its customer service reps to "cover their tracks" this way Frontier has a systemic problem that management must be aware of. So much for improving customer service. Hence, if you deal with the chat line (as you must; it's the only way Frontier allows) take screenshots of your dialog as you go along.
