Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

It was as good as it could be. Flying is not a pleasant experience these days.

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

Got on the plane and sat there for an hour before departure.

5 hour delay. They blamed the weather but it was the computer issues they had been dealing with for days.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

long flights are never truly comfortable but the airline did their best. crew was great and the flight was safe.

The captain was amazing and kept us informed throughout that there would be some rough air. The flight also got delayed but we were able to actually leave on time, which was great.

The staff did not do a good job of getting everyone boarded quickly, so we missed our take off window and had to sit on the tarmac for 20+ min waiting for our turn. The plan was old. Pockets on the back of seats were torn and tearing off. One of the attendants was rude-she would ask a question but he walking away before you finished answering so she kept getting our drink orders wrong.

Flight Crew Review The crew was absolutely amazing from start to finish! They were friendly, professional, attentive, and genuinely made the flight feel comfortable and enjoyable. Every interaction was pleasant, and they went above and beyond to make sure passengers were taken care of. You could really tell that they cared about providing great service. I truly appreciate their kindness and professionalism and would be happy to fly with this crew again!

stood in line to check in luggage for nearly an hour. very poor service and not excusable

Same as the previous flight as far as comfort and food. Entertainment didn’t have a watchable screen so everything would need to be watched on your own device in which they didn’t have a charging port that accommodated my iPhone. Seats were very uncomfortable. Staff was very friendly.

Do not book it’s a scam! They stole $1200 from me

Flight got delayed; had to go through security three times.

A lot things happened in this trip.The fly should be less stress.

Some of the Air hostesses are not that friendly. Need improvement

We had a great flight just wished they had a tv so we can see a movie that would of made my trip excellent.

I would like a glass of wine or some kind of alcoholic drink.

Very long delay but we just made the connection. The requested wheel chairs were not there so I had to assist/carry BOTH of my parents to the gate while carrying their bags so we could make the connection. The plane had no entertainment system and NO WIFI, legroom zero. Restrooms on ALL of flights were dirty and one restroom did not even work properly. I was surprised to see COPA like this since my flight with them in 2013 was incredible, the seats were amazing and the food options were spectacular. Of course, I see this kind of service on many airlines now, with services and hospitality at an all time low. The worse part of the trip was seeing my 90 year old parents go through hell on these flights and having to try and rush to a gate to make the next flight. Never again

Flight was great. Almost miss my connecting flight due to late departure from Haneda. Had to run all through airport in Chicago to make the flight. Experience was great for 1st time flyers using ANA Airlines.

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

Seats are complete BS for 10 hrs. The guy at counter canceled our return flight from europe. Lufthansa on the way back made United look like a trailer park gathering. If given the opportunity, I will never fly united again. Lufthansa seats werent much better to be fair but the service was a 10 out of 10. Incant express how difficult umited made my trip.

It was a great experience to fly with ANA, the sit is very comfortable.

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

I’m an EP on AA every year for more than a decade but this was a very pleasant and surprising experience. Clean and sizable plane for HOU to CHI. 5 row first class. And excellent food in first class the steak option was really good. Your flight attendants even better. Seat 5A

Gluten free snack options and meals that offer both gluten free and dairy free.

Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

I almost missed my connection in Chicago due to having to wait on a gate to be open I am assuming. Having to run from E terminal to C terminal and I barely made it there before they closed the door. This may not be the actual airline's fault it's crazy how there is so little time between flight especially when they are placed so far apart in the airport.

Delays and cancellations. Mechanics weren’t on site. Replacement plane took hours to arrive although it should have arrived within 90 minutes. Flight back was cancelled. Ended up driving over 12 hours and wasting 3 days between everything.

Little bit of trouble getting my KTN and pre-check status onto the ticket, but otherwise the counter staff were friendly and truly concerned to get it right.

The flight could have actually taken place. Canceled flight and no option to rebook that day.

Missed connection from delays and times changing multiple times and then involuntarily booked on another airline next day

The flight was delayed in 30 minute increments for a total of 4 hours and 30 minute delay. All other flights to Chicago left on time except for this one flight. If there is an issue with the inbound flight, just let customers know so they can find another flight right away, Once we got on the plane there was another 30 minute delay taking off at 10:30 at night which is very unusual that a flight wouldn't be ready to take off

My seat had a worn out cushion, which made it a bit uncomfortable. Other than that, the flight was excellent.

Take this flight regularly. Every single week same thing. Departure delayed. Make up some time in the air. Land at ORD and then wait for gate in "L" concourse Terminal 3 for 30-40 min-which yields a very delayed final arrival. Plus I get to taxi around and see every runway and drive over the bridge (IFKYK) over the expressway 2-4 times in most cases. Change the sched of incoming plane/work with FAA to improve traffic flow at ORD/change the timing of these flights. Whatever it takes. But do better.

- flight was delayed several hours due to weather (understandable) - flight delayed further and we were told by attendants "we are not sure where the pilots are but they are on their way" as we have to find different pilots for the flight - announcements over the PA were somewhat unprofessional by the attendants, seems they need more training and were not reading off the script. They showed their young age and immaturity in their communications with the passengers. They were not clear and lacked professional communication language. - going from a hub to hub we were also parked at the tarmac at ohare for an additional hour and kept being told "few more minutes". Please just let the passengers know the real wait time instead of hiding the truth. We understand there is traffic and weather delays, but we just want transparency. There are several logistics of our lives that revolve around what the attendants and pilots are sharing with us but they are not being transparant.

Boarding and Delays The boarding process for my American Airlines flight from Copenhagen to Philadelphia was a bit tricky. We experienced a gate change that required a long walk to a new area of the airport. Additionally, boarding was not via a jet bridge; we had to take a shuttle bus to the plane and then carry our luggage up the stairs ourselves. Furthermore, the bag drop didn't open until about 12:20 PM, which was only three hours before our scheduled departure. This meant I couldn't drop my bag off early and had to wait outside of security in order to drop off my bag and use the kiosk. The bag drop self-service kiosks also didn't open until about 12:00 PM when an American Airlines employee unlocked them so that we could print out our boarding passes and bag tags, which further created a backlog. The flight was delayed by over an hour because we had to wait for one of the tires on the plane to be changed. Flight Attendant Professionalism On a positive note, the flight attendant was very professional when handling a passenger who was sitting in the wrong seat. Even though the passenger was persistent and reluctant to move, the flight attendant calmly ensured the assigned passenger could take their seat. Kudos to the flight attendant for keeping his calm and composure, not allowing the issue to escalate, and handling it well under pressure while a line of passengers waited in the aisle to board. In-Flight Service The in-flight service was also fast, prompt, and efficient, although service had to be suspended for the last two hours of the flight due to weather and turbulence, which was outside of the crew's control. Limited Flight Options Please note that American Airlines only operates one flight per day in and out of Copenhagen. This means there are limited options available if your flight is delayed or canceled, which is something to take into consideration when booking.

This may have been the hottest cabin temperatures I have experienced on any flight prior to take off lasting for approximately 30 minutes. I am not typically one to complain but I was genuinely worried about the health of several passengers on the flight due to the extreme temperatures including a small toddler.

Better seats, allow us to upgrade, terrible website, poor telephone service, better equipment

Horrible experience with Avianca, they delayed their flight and when we arrived to NYC, AVIANCA took 1 hr y 30 mins to park the airplane and all passenger get off the plane, it made me lost all my trains to get back home and I came back to my place at 3 am instead of 12 am. On the top of that their plane seat are so uncomfortable and is not enough space and killed my legs and knees, Avianca used to be good when it was a Colombian company, now after Brasilian company bought them, their service quality is bad and their flights are delayed and oversold.

I handed in my suitcase in perfect condition at SAL Airport. And in MIA Airport I received it with one corner broken and the wheels bent.

I like the crew members they're very friendly. Clean plane. The flight was on time. I dont like the comfort my car seat its better that the plane seats. They charge for everything. This airline was very good. Now it's a low cost airline

6 hour flight and have to pay for everything 100 dollars to add a carry-on bag is insane

The check in is the only positive thing in Avianca. The seat is the most uncomfortable I have traveled, the distance is minimal.

Not what it used to be. The sale of food makes them look greedy!

Avianca is not what it used to be. So disappointing

It was horrible. My experience with Avianca. I didn’t know it was Pakistan international Airlines but anyway, whatever it is it is bad horrible you guys need to upgrade everything in those planes. And you guys charge $130 for a carry-on did they wanna let me in with my carry-on that I travel everywhere with the luggage you guys are such a dog thank you

why did we have to go through security mid flight
