This is a no frills, get it done, efficient airline. The seat is a lawn chair. You better bring your own entertainment. If you want something other than water you need to pay for it. But they will get you to your destination quickly, on time, and then they will turn the flight around and go right back where they came from. Reliably. Couple times a week tops. If it fits into your schedule, you can’t get there cheaper or faster.

A three hour delay to board and then another hour on the tarmac because they couldn't get a tractor? Ugh.

Allegiant canceled the flight. The flight the next day was full. Allegiant did not provide any compensation besides a refund. Last time on Allegiant.

Seats were very uncomfortable and being charged for snacks and water.........

Allegiant actually impressed me, original inbound flight from PBG was so late they gave us a bird inbound from Des Moines and only left 1h late and gained 40 minutes back in the air. Comfortable flight with no frills but no complaints.

Flight was delayed. Crew was good but hot coffee was not available.

Great. No choice for n/a. No food or entertainment options

No food is available without purchasing it and there is no in-flight entertainment. Both of these are OK because we got an inexpensive flight from Allegiant and, otherwise, our experience was excellent.

just had water and there was plenty of leg & seat room. But then i don't weight 220#s!!

No complaints. It’s a budget airline so can’t expect any frills.

Flight was delayed 5 hours. Initial reason for delay was 'maintenance' - which makes sense. Then, the additional 2 hours continued to say it was maintenance - when I know EWR had a 2 hour delay. AA did not say that. Additionally, when boarding, there was only one agent at the counter for a long time - until another came to help. After boarding, we had to wait another 45 minutes due to 'no catering'. So while we waited for catering, AA continued to board additional passengers - which seemed odd - and raised questions about what really was going on. I sat in First Class. During the flight, the flight crew allowed a significant number of non-First Class passengers to use the front bathroom - which created a very crowded environment in First Class which was uncomfortable. This also delayed First Class passengers from using the bathroom. Overall, horrible experience.

Returned home with a blood clot from flight homes and the uncomfortable aircraft I was on.

Seat was VERY uncomfortable. Flight was delayed and then boarded slowly. The crew was super helpful with boarding and supporting maximizing the luggage in the overhead.

Absolutely terrible. Would never fly American again. 2 deplaned incidents and delayed by close to 24 hours. $12 meal voucher for first class passengers was an insult to the injury. Pathetic.

Delayed, no updates, had a rewards number but was not working

Newark airport grounded inbound flight and only announced when the flight was about to start taxing.

I'm not a valued flyer so I'm always in the last group to board...that sucks, always

My flight got delayed for almost 4hrs and then it thankfully went to only 2hrs. Then we were told that there were no space for carry on bags and I had to get it checked... well I counted at least 8 spaces that weren't used and I was one of the few left that actually had one. There was definitely enough space and either the crew can't count or just genuinely are so lazy they don't want to do their jobs correctly and make sure that there ACTUALLY is no space.

Boarding can be more efficiently done by having the back row passengers board first. This way, the other people do the have to wait for front row passengers to load their luggage in the overhead cabins. Food is simply pathetic for the price I paid. Cleanliness is simply poor; my seat was full of crumps.

My morning PHX to NY flight was canceled. Not a cloud in the sky. No wind. No weather across the country. My guess is they canceled the flight because they didn’t have enough people or a mechanical issue. Either way really bad. I checked it at midnight and the 830a flight was on time so I was very surprised when I woke up to see the flight canceled and I’ve been rebooked on a flight… An hour earlier than my originally scheduled one. Of course I missed this earlier flight because AA texted at 4 AM when I was sleeping. I was re routed to Miami, boarded a plane, sat in the heat for 40 minutes, then boarded because of mechanical issues and had to wait another hour before finally getting to New York Ironically, the 430 Phoenix to New York flight landed at the same time I did… I could’ve been sitting at the pool all day vs jumping through hoops. never ever will I again fly American Airlines. No offer of a free drink, maybe a few points on my advantage account nothing… As if nothing happened and they did not inconvenienced me at all. I’m so sick of the dumb crackers that they give us on these flights. It’s really like a budget Airlines these days. A far fall for s once mighty company.

Crew was kind of grumpy and there was no beverage service at all. Sodas were $4. Disappointing.

There weren't enough employees at check in took awhile to get bags checked. There wasn't a wheel chair for me, I was sent to someone who turns out to work for a different airline, if My flight hadn't been delayed I probably would have missed my flight as it was, by the time I arrived at my gate, they started boarding in about 15 minutes. I don't know who took me to my gate, definitely was not the normal people who take passengers to the gate. I'm guessing she may have been in a management position. I wish I knew her name, she went beyond to help me. With that said everyone was kind, and were doing the best they could. So, I choose to say it was an Adventure, stressful start, but good. In the end went well. The situation was not only difficult for passengers but the employee's.

The staff at the check in counter was so rude. Made you feel Incompetent

Frontier scheduled a 40 minute connection in DEN. What they failed to mention was that they “close the doors” 20 mins prior to departure, which means you only have 20 mins. Not enough time. Possibly against DOT regulations. Filing complaint.

Flight was scheduled at 9:40pm. Got delayed to 10 am, the next day. crazy

The bag check, flight check-in, and onboard experience convinced my wife and me that we will actively go out of our way to avoid flying Frontier Airlines in the future. At bag check, we were informed that check-in could only be completed via the Frontier mobile app. Unfortunately, the app was extremely frustrating—sending us through repetitive, confusing loops that repeatedly forced us to decline add-on services with nearly every click. While most airline apps upsell, this one felt intentionally exhausting. As the process dragged on, we became genuinely concerned that my phone battery would die before check-in could be completed. We approached the bag check staff—who were standing together talking—and explained both our frustration and our predicament. They laughed. Later, my wife described the interaction as “gaslighting,” which felt accurate. We were then informed it would cost $25 per person simply to have our boarding passes printed. From that point forward, the tone of the experience was consistently hostile. The bag check employees were condescending and combative, behaving more like bullies than customer service staff. Unfortunately, that same attitude continued onboard. One flight attendant argued with me when I attempted to stow my backpack in the overhead bin. I explained that we had each paid $75 to check our bags specifically so we would not need to use carry-on space and could have adequate legroom. She demanded to see my ticket, pointed out that it said “no carry-on”—which I acknowledged—and I reiterated that this was precisely why we paid to check our bags. Her response was, “I don’t make the rules.” She then walked away, but not before asking if I “truly wanted to fly back to Chicago today?”—an unnecessary and unmistakable threat. It is also worth noting that despite booking our tickets together in the same transaction, we were not seated together. Upon our return to Chicago—where we could once again sit together—we compared onboard experiences. We both remarked on how unhappy the flight attendants appeared and how each of us was separately asked whether we would like to purchase a beverage. We declined. At no point was water mentioned as an option, leaving us with the clear impression that even water came at a cost—or that complimentary water, if available at all, was deliberately left unmentioned. Overall, the experience was shocking and deeply disappointing, but it was also a profound learning experience—one we will not forget and will not repeat. -Steve

Plane was hot and miserable and the crew was rude!

12 hour delay required getting on and off plane 3 times - would have at least liked to have been offered a snack or drink

Our flight was on time and unremarkable which I'm grateful for, as it is not the norm traveling these days. Frontier is a low-cost carrier and it really shows when compared to other "normal" carriers. They don't even give you water during the flight. The coach seats are decent, however it was not as clean as it should be. We had crumbs all over the floor by our seats.

The ground crew in the Tampa airport were forcing people to pay for their personal items, although they met the measurement criteria. They receive $10 for each bag they charge passengers for so this is a complete fraud. An investigation needs to take place and the ground crew that does this need to pay the price, and the Airlines absolutely needs to make it right for these passengers.
