Flight coming out of Buffalo was delayed, so we had to be rescheduled on another flight from Baltimore to Phoenix which means we had a long layover and got home 3.5 hours late. Shuttle to parking stopped at 10pm, so we had to pay for an Uber to the parking lot and got charged an extra day of parking since it was after midnight. Not the best experience. Long day!

Flight coming out of Buffalo was delayed, so we had to be rescheduled on another flight from Baltimore to Phoenix which means we had a long layover and got home 3.5 hours late. Shuttle to parking stopped at 10pm, so we had to pay for an Uber to the parking lot and got charged an extra day of parking since it was after midnight. Not the best experience. Long day!

One major problem that was very unprofessional and uncalled for. Plane landed and we had to wait 20 minutes to get off the plane since they were waiting for someone to come to the gate to drive the jetway. Southwest couldn't have someone available and waiting for the plane to land? Is there only one person in Hobby airport who knows to drive the jetway? Was he at lunch? In the bar? Uncomfortable and uncalled for!

Southwest is kind of a slum airline. It’s gotten more expensive over the years for less and less service. I am a Southwest Chase Visa card holder and was forced to choose a seat in the 26th row in the middle seat. However my wife who is a rewards member but doesn’t hold a card or anything else, gets randomly assigned a normally paid seat in row 6! How does that work?

The seat was not comfortable. 1D. My back was sore all night and the next day.

One of the best airlines for fast boarding, on time arrivals, and top notch service!

I elected to pay for the upgrades and found very little difference

The new seating arrangement is so over priced for what you get.

Snacks are always pretzels. Why can't you also offer peanuts ?

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

An entire day of delays. Cost lots of money. Meals and a hotel.

Third flight in two months where the crew was not there. Comfort seating does not guarantee overhead bin space. Passengers with children are allowed on the plane first - if you are flying to and from Orlando, this means half the plane has boarded before you get on. And somehow all the bin space is taken up. 3 out of 5 flights have had issues with equipment or procedure. Some of these instances caused the flight to be delayed because of a "nuisance" light. One time it was a bag that had been brought on board but did not belong to anyone so we had to return to the gate. Last night we were told the "AC" on the plane doesn't work well and we're 10th for take off- because the crew was late - and that it will get cool when we're in the air. Not sure if this is usual, but I didn't think flight crew could jump seat in first class. Movie and TV selection has not been refreshed for several months- flying one to two round trips each month easily exhausts the list of content.

Great experience nice pilot very soft and easy landing and take off

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

On time! There were plenty of airport employees who were able to keep us moving in the right direction. The crew on the plane were professional.

I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

Was revoked with Jet Blue due to delay from Kenya Air

WiFi didn’t work. Flight delayed 3 hours Crew members were illiterate Seat lean back did not work.

Transparency from pilots, quick boarding and exiting the plane, staff greeted to each and everyone,

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.

Flight was delayed three times and we had an international connecting flight which we would’ve missed but AA manage to find us a flight that allowed us to catch and we made our international flight. However, due to the flight change, I’m in Amman, Jordan missing all 4 bags. It’s been a nightmare. Been waiting since June 17 and today is June 20th. Still without luggage. Customer service wait times are two hours and I get disconnected while waiting. I’ll update when/if my luggage arrives. Every day is costing money in a hotel in Amman. I can’t continue my trip to Palestine until the luggage arrives. Then, I will be updating my review.

Flight had mechanical issues and it was delayed 30 mins - some of us boarded and then had to deplane.

Awfully rude American worker at door when we started boarding flight. Then, walk into a blazing hot airplane with no air conditioning until twenty minutes into the flight. Free entertainment was non existent! My husband, along with the fellow passenger in our row, and I could not get entertainment to work, no WIFI! Really?? Been flying American a long time. Was very disappointed.

Leave on time. We waited on the plane for hour hours and it was hot and smelly

I’ve got 31F seat and window seat . My 2 co passengers was AA crew members and they were very rude attitude and when I was going to use bathroom their gestures was very different and awkward and the guy beside me completely occupied the hand rest and I was really uncomfortable

The gate experience at LAX was abysmal (same for the arrival experience two days prior). Despite the LAX -> SAT schedule of two flights daily, our departure gate was at a smaller hub that we had to be bussed to from Terminal 4. Fortunately, I arrived at LAX extra early and had time to spare, but if I had not known, I might have missed my flight. I looked at the LAX airport map in the AA app and there was no indication of the additional boarding process. Lastly the gate area we were bussed to was crowded with limited food and beverage options. On flight, the fight attendant was hospitable and attentive, the flight was smooth, and AA's free (and working) wifi for AA members were all on the positive side.

The flight back to Dallas was delayed, which has happened to me several times with American Airlines. There was no announcement, no update sent out, no compensation offered for the inconvenience.

As always, most AA flights that we fly are almost ALWAYS delayed and that too multiple times. Very frustrating

Boarding was smooth and seamless and the flight was without incident.

Food is what you expect on a plane. Nothing gluten free. But that is expected. Drinks, apple juice, was fine. Seat, what I expected. Fine.

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

They didn’t offer a water, even after I asked

They switched our terminal 3 times and we were delayed for four plus hours!!!

It was an early flight and most people napped/slept and the crew let us which was nice.
