Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

The seats were really comfortable. Flight crew were friendly with passengers. Overall was a great flight.

Great crew, flight on time, luggage pick up a breeze

Was on time, normal boarding. The worst flight attendents and service I ever seen,, can't believe Delta can have such service. Bathroom was dirty and no toilet paper, paper towels and used toilet paper all over the floor, when I tried to tell flight attendant she didn't even let me to finish and turn around. Very rude. Wi fi didn't work.

Flight was delayed. Then eventually cancelled. The female staff that was announcing overhead was unprofessional. She was telling everyone that the company is not going to give any money for taxi, hotel etc. then eventually the flight was cancelled.

Seats were comfortable, 8 hours. One flight attendant was not appropriate in his verbal response: "Please, DON'T touch me.", after being tapped near his elbow after being made unaware he skipped serving me & had passed further down the aisle.

The baggage belt was not updated on the Delta App and was displayed on the wrong belt board. Was not expecting this to happen.

Landed without a gate ready. Plane is extremely old and dirty.

Wonderful crew, great movie selection and good food. I prefer Airbus to Boeing, much more comfortable

Got to fly my favorite plane, the Boeing 767-400ER, to Milan. The soft blush pink mood lighting during meal service was very beautiful and gorgeous. The service was top-notch, and our flights were on time. I highly recommend Delta.

Agency very bad had to cancelled my booking too many changes in the flight changed my flight to 1 week

The middles seats on the 777 airplane are very small. I am only five feet tall and my knees were touching the seat in front of me and the is no leg room if you have a person item under the seat. The food was horrible, spicy sauces, tasteless bread, and wilted/brown lettuce. Keep it simple. The staff was mediocre., one minute loud and chastising, and the other friendly. We liked how clear and easy to understand the entry process in to the US was.

Our flight from JFK to Madrid was delayed. We had to go from one side of the Madrid airport (Terminal 4s to the far end of terminal 4 - Gate K98) to our gate in less than 30 minutes. Put passport control and security/baggage check and that’s very hard unless you’re Usain Bolt. I called Iberia Airlines and the telephone customer service told me that I was going to have to pay to re-book. Luckily the help desk in the airport (who was dealing with dozens of people from the same JFK-Madrid flight) did not charge us extra to reschedule to a flight 8 hours later. They also gave us a voucher for breakfast and lunch. Glad the actual person at the airport had some actual sense.

Our flight was repeatedly delayed for maintenance problems: scheduled for 9.30am, eventually delayed to 7pm! Very very inconvenient! AA should have provided a substitute plane much earlier.. On the other hand, Customer Service crew in Charlotte helped us to reach NY (LGA) by late afternoon. Thank you Patricia!! The actual flight was quick and very comfortable. As always a. excellent, professional crew. [no food on a a short hop).

The flight was peaceful, just s slight turbulence, pilots and crews were all nice and made a great job! Arrived safely in the Philippines. Thank you ya’ll!

Boarding gate at LAX was too crowded—two gates next to one another

This short sector between Miami and JFK was undertaken purely for business purposes, with efficiency as the primary objective rather than a full inflight experience. Overall, the journey met its intended purpose; however, the ground experience at Miami stood out significantly. During check-in, I was unable to link my frequent flyer details from Qatar Airways (oneworld alliance) through either the self-service kiosk or web check-in. The situation was handled exceptionally well by the check-in agent, who demonstrated remarkable ownership. She coordinated across multiple counters, ensured my frequent flyer number was correctly reflected, reissued the boarding pass, and confirmed that mileage accrual would be recognized. Additionally, she ensured the boarding pass reflected priority status, enabling a seamless priority check-in experience without delays. This level of proactive service was both commendable and impactful. Boarding and the inflight experience, operated by American Airlines under a codeshare arrangement, were efficient but largely transactional. While operational delivery was smooth, there was no visible recognition of oneworld frequent flyer status onboard. In comparison to the consistently personalized engagement typically experienced with Qatar Airways, this absence was noticeable—though understandably a potential limitation of codeshare alignment rather than a direct service shortfall. In summary, while the flight itself fulfilled its operational intent, the exceptional professionalism and commitment demonstrated at the Miami check-in counter was the defining highlight of this journey. Greater consistency in elite recognition across partner airlines would further enhance the overall experience.

A chaotic and uncomfortable experience from start to finish. The boarding process was a disaster; despite group numbers, it was a free-for-all that the staff failed to manage (especially after group 5). Once on board, the "entertainment" was non-existent. There are no seatback screens, and the mobile app selection is incredibly thin. The hardware is severely dated. My seat had zero cushioning left—it felt like sitting on a hard board for the entire flight—and the legroom was cramped. To make matters worse, the bathroom was repulsive, with toilet paper, soiled paper towels and liquid/pee all over the floor. When I did interact with the crew, they provided the absolute bare minimum and made me feel like an inconvenience for asking for anything. Avoid this flight if you can.

We left at 1030 am pacific from LA and supposed to land at 7 pm Eastern in NY. They made a detour, stopped in Philadelphia and didn’t land till 1130 PM Eastern!!! Worst flight experience with no pilot communication with no explanation as to what was going on. Everyone was very frustrated to say the least.

Found that the plane used for this short flight is smaller and therefore the seats are really squeezed tight.

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.
