Plane was clean and comfortable. Flight attendants and gate staff were professional, friendly and efficient. Boarding and deplaning were orderly and efficient. All in all, the typical excellent Southwest experience.

Not having a five hour delay with little notice! The crew was very kind, though, and just as tired as we passengers were. The flight didn't depart until nearly 1 am...and no reason was ever given.

This leg was much better, but we did have to have a 3 hour lay o er after coming from a very exhausting hiccup with our flight from BNA to Den

The Air hostess were very rude on my flight from Houston to Austin . Their regular communication itself felt a they are shouting at people.

Boarding was easy. The seats are small and fairly uncomfortable

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

Mediocre. Boarding is now unpleasant. The employees, once friendly and nice, are now regularly speaking sternly to passengers, badgering them to do things right so they can take off on time and gate check bags because they don't have enough overhead bin space. The pretzel snack was crushed flat and broken into even smaller pieces, which happens frequently lately. Drink service was suspended before they reached my row.

The charges were ridiculous for an hour flight and the turbulence was very scary.

Everything went smoothly, although the usual gripes about airline travel were still present: the boarding process is inefficient, the snack selection is limited, and so on. Since there was extra space on the flight, the gate agent rearranged many people's seats to put people on the aisles and windows, leaving the middle seats empty, as much as possible, which was pretty great.

While they turned off most cabin lights to allow people to sleep, I was bothered by how bright the side lights still were. It was still quite bright for me in a window seat, when I wish I could have slept!

One of the flight attendants was a little cranky. I appreciated the free wifi and plug to charge my laptop

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

The crew bent over backwards to thank us for flying and make us comfortable. The food service was quick and efficient. The Captain communicated and said goodbye and thank you as we departed. They really stood out!

Generally on time departures and arrivals, clean planes, sky miles membership provides great benefits (complimentary upgrades, etc).

my mom urmila patel needed a wheelchair which was not available on the curbside. she needed to walk almost 50 meters inside (at the risk of falling) and then had to wait in line to get a wheelchair (this is not ok). Once obtained she had to seat in it for 30-45 minutes for someone to take her in thru the checkin process (which was fairly smooth and easy). the lady who helped her with her checkin process was very courteous and helpful

Staff at the check-in counter were friendly, happy and helpful. They tagged our bags and sent us to “bag drop off” but were not very clear about where that was. The airport was busy we headed off in what we thought was the right direction until a gentleman waved us down and actually came after us. He was the baggage handler for Delta and recognized our “deer in the headlights “ look-he brought us to the right area (which was marked as the Southwest Airlines Drop Off) and sent us on our way. Wonderful guy, low key and working with a big smile on his face. Loved it. Loved him.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

Like: flights are on time, good boarding process Can improve: planes are old, improve entertainment and make space more comfortable

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Flight: Started on time. Comfortable flight. Arrived on time. Crew: Very cordial and helpful. Drinks and snack was served with a smile. Overall enjoyed the trip. Regards, Hari Doss Chanchala Doss

To have arrived on time and not 3 hours late after having already spent $100 to change to an earlier flight, only to arrive back home close to the original flight time.

American Airlines is a miserable experience. It is predictably miserable, in the sense that every time I fly American, I brace myself for the certainty that it will be unpleasant and uncomfortable. But it is unpredictable in the sense that I never know if the flight will be on time or delayed nine hours (both happened to me this week). I never know if I will be able to sit in the seat that I selected when I purchased the ticket or if I will be told by Customer Service (!!!) that I must relocate from first class to a seat in the back of the aircraft with no explanation (both happened to me this week). Will the food be frozen and half defrosted, or scalding hot? Will the drinks be warm? Will the flight attendants be surly and mean? Will the toilets be cramped and foul? Will the seats be narrow and uncomfortable? Will there be a real electric outlet at the seat, or just an unreliable USB-2 port? Will there be enough seats in the boarding lounge or just a few? Will the boarding process be smooth and efficient, or will the gate agents mess it up and delay it needlessly for 30 or 40 minutes? Will the catering and cleaning crew be prompt or will they take an extra 30 minutes? Will the brakes on the aircraft work properly, or will the pilot delay takeoff for four hours while the ground crew attends to what can only be described as routine maintenance that should have been done the night before? I've eexperienced every one of these unpleasant things this year, 2026. The only thing I can reliably count on is that American will find a new way to make the experience of flying as miserable as they possibly can.

Wifi was spotty. Tray table was very dirty when I sat down.

The WiFi would not connect enough for me to do my actual work. It permaspooled, disconnected, said it was connected, then wouldn't open an email... it was frustrating. I am not a tall person, 5'4" - and I felt cramped with little room to reach into my bag under the seat in front of me. I feel sorry for anyone taller than me having to fly. the one positive thing I will add, is the overhead bins are roomy enough to manage more bags than other carriers.

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

Delayed for mechanical and no updates on what was happening and how long the delay might be.

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.

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.

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

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

Good for a budget airline! It was easy to get on, staff was really nice. Can’t say anything about the food or entertainment because it wasn’t available, which is fine.

It was costly and difficult to check in. $85 to take a small suitcase with me, carry on or checked and $75 on the return trip, Plus $25 if I didn't check my self in check in $25, because I couldn't do it on the kiosk. Small very uncomfortable seats, waited on the runway for near an hour each way. It was my worst flight to date.

Horrible. I would never fly Frontier again. The booking process is tricky at best, but fraudulent in my opinion. Frontier customer service did nothing to rectify my purchase -- I ended up paying more than double what I could have gotten from other airlines and nearly triple what I thought I was buying from Frontier. Their booking practices are unfair to the consumer.

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.

i was unable to check in the flight. refund requested

I think Frontier was very good at communication. Their app worked very well. Loading was great and the flight was nice and easy.
