Trash experience on all my flights this week. Delay after delay. The flight I’m waiting for has been delayed 6 times and nearly 3 hours.

Exceptional. The gate crew responded quickly and got me onto this earlier flight as the final passenger, saving me more than four hours of wait time for my reserved flight.
The flight was delayed due to earlier issues at other airports. The crew was excellent & made it a good trip.
Snacks are always pretzels. Why can't you also offer peanuts ?
Only downside was the legroom and seat width, which is always a problem unless I spend more for a premium seat.
Very good. Sad to learn Southwest is going start to charge for bags
Exceptional crew! Friendly and professional. Pleasant attitude and treated everyone with respect.
The flight was promptly on schedule and Southwest delivered everything they promised. No excuses for any shortfalls just 100% ownership of their responsibilities and business. The boarding and seating policy is a complete shambles. What started out as a great idea when Southwest first hit the market has been turned into a disaster due to the lack of integrity in many of the people who fly Southwest and take advantage of Southwest generosity at the expense of their fellow passengers.
Crew was excellent - Plane was fine. Media was good, could use more kid shows; Not a fan of the brownie brittle -- snack could be slightly better.
Left on time and arrived early. Brand new plane and no parts missing. Comfortable seats. The actual Captain spoke prior to the flight and reassured everyone about safety. Crew was so nice and fun. Perfect flight!
The flight was delayed and knowing I was going to miss my connection, nothing was done proactively to try and get me rebooked. It was an act of congress to do so. This is not on the crew, but on the experience itself
Your survey needs a N/A option. I didn’t use the entertainment or eat food.
Flight was delayed multiple time and for more than 1 hr. My onward flight from BOS to MCI was also delayed. These delays have caused me so much inconvenience and Delta does nothing to ensure flights take off on time. No one knew why the inbound flight was delayed and what was the issue.
Our flight was delayed by over 4 hours due to a maintenance issue. They announced a new plane was on the way. We were given a $12 food voucher ( airport food is quite expensive You can’t even by a water and a small snack for 12:00. 4 hours later we boarded and landed in Atlanta at 10:20 ish pm. Of course we missed our connection and we were given a hotel voucher and another food voucher ! We didn’t make it home until 11:00 the next day ! Unacceptable
From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.
Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!
My flight was canceled after being rescheduled for four days canceling my trip. Kayak and everyone affiliated with it I.e the airlines, and just fly have been excruciating to deal with. My trip to visit family had to be canceled as there was no way to make it. I am furious at all of you.
They delayed our flight because of bad weather in NY which was completely understandable. Then they cancelled our flight and a later flight that evening. The earliest we could fly was the next morning. We ended up buying last minute tickets on another airline and made it home slightly delayed but safely that evening. Delta kept saying it was weather related but if that was the case how did we make it back on another airline? The weather in NY was cloudy but not bad.
The plane smelled like a sewer. Multiple passengers complained. It’s a safety and quality issue to clean these planes.
We were delayed 2 hours leaving STL. I had 20 mins from when we landed in SLC terminal A to make it to SLC terminal B. I had to actually run! thankfully I made my flight but 3/4 legs were delayed to some capacity.
Great Brasilia aircraft - not a Boeing 757 like the next part of the flight. Flight from MCI to IAD was great, on-time, comfortable, did I mention that? The flight from IAD to EDI was painful. One of the reasons I won't fly United again? Boeing 757, with a seat pitch and material that was horrendous. Worst aircraft ever, made worse by United sardine-can tight seating. Oh, and the connection window, 45 minutes, really? At IAD, in different concourses? What idiot came up with that flight scenario? Happily, (for me and my travel insurance people) the flight was late (reminiscent of American Airlines). The crew was professional and courteous.
On boarding crew at the airport called in the boarding numbers too early meaning before the previous line was completed resulting in later numbers getting to board ahead. Also she asked those who boarded from number 3 to have the tags in their carry-on bags and leave it in the jet bridge. Most of the overhead bins were empty though. This is more work for the ground staff in addition to more inconvenience for passengers waiting to get their carry-ons from the jet bridge.
The flight to America was freezing. The overnight flight back to the UK was boiling hot and the cabin stank of toilet or occasionally perfume, even though I was several rows back from either bathroom. Food was tiny portions. Two small pieces of tough and dry beef in random gravy with pretend mashed potato raking up most of it. Very little veg. Salad was ok. Wooden cutlery broke within minutes of using. Lots of old films for entertainment. Some new ones. Generally a bit rubbish.
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.
Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.
HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.
Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.
Overall a very poor experience - booked premium economy tickets but due to last minute flight delays , all my itinery went for a toss and had to fly economy class with no access to lounge or any compensation by united airlines to make up for the flight delays . i had expected better experience than that from united.
Onboarding - it would be great to see on the screen what group they were boarding. It was very confusing on who was boarding (even though they called it out) they were not clear and the space to board was strange.
Older plane. Food was really bad, almost not worth the effort. Huge difference with European based airlines.
I was assigned the last seat in the last row directly in front of the bathrooms at check-in when there were plenty of open non-upcharge seats available. That seat should not be given out unless it’s the absolutely last one available. I had traveled/waited for over 10 hours and to get that seat on my final of 3 flights from Rio was a slap in the face.
I bought the ticket as a work/ business issued ticket, meaning my company probably payed extra for a flight of I bought by myself I would avoid let gol manage the entire reservation with its partner America. The App from gol and America were not able to properly handle check-in and information about the trip. Creating unnecessary confusion, also preventing properly define seats even by paying the fee. The boarding on Miami was in a very disconnected gate, that had limited access to other gates and food. So, I would avoid this route in the future in my travel. There are better routes.
GOL turned out to be a very decent airline . To be honest better than I expected.
Was given all 3 boarding passes. Was refused boarding to Brasilia in Miami even though I had up to date Brazilian Visa and US passport. Had to return to Phoenix as trip was cancelled. Waiting for refund of the fare. Missed my son's birthday and visit with him and his wife.
The pilots landing and taking off was very bad on the first flight, the second one taking off was great but landing was also rough
The check in and on the ground experience is very poor. Their online check and trip management is the worst I have ever seen and they have long lines to check in at the airport, technology is glitchy/unusable and have exorbitant baggage fees. The flight itself is fine, although the food is about what you would expect and their was no functioning entertainment for an international flight.
My experience with this flight was extremely negative and resulted in serious financial and personal consequences. The flight departed with a significant delay, which caused me to miss my international connecting flight. As a direct result of this delay — which was entirely beyond my control — I was unable to reach my final destination on time, causing me to lose a previously scheduled hair transplant surgery that had been arranged months in advance. This was not a minor inconvenience. The surgery involved: • A reserved operating room • Medical and technical staff scheduled specifically for that date • Surgical instruments prepared in advance • Strict scheduling that does not allow for easy rescheduling Due to the airline’s delay and poor handling of the situation: • I lost already paid international flight tickets • I was forced to purchase new tickets, incurring duplicate expenses • I spent over six additional hours in airports, under stressful conditions • I incurred unexpected costs for meals and transportation • I lost a medical opportunity that cannot be easily recovered, along with the emotional distress associated with it Although the airline covered one night of hotel accommodation, this did not address the real impact of the delay, nor the significant damages caused by missing a critical medical procedure. The lack of punctuality, planning, and effective solutions reflects a serious lack of responsibility toward passengers, especially when international connections and time-sensitive medical commitments are involved. I do not recommend this airline for travelers with important schedules, medical appointments, or critical connections. In my case, the delay did not merely cause inconvenience — it resulted in the loss of a surgery and substantial financial damage.
I was not able to get on the flight due to delays out of Philadelphia. I arrived in MIA at 10:30pm and there was no one at the GOL Desk. Is there any flight credit available for this flight?
Unfortunately it was very disappointed experience. Our first flight our was delayed 2 hours, as a consequence we missed our connecting international flight. Customer server at Miami American Airlines was very disrespectful, gave us the worst replace itenarary for the next day that we had to spend 2 hours calling Gol to get a better itinerary otherwise we wouldn't make it on time to fulfill our trip purpose. We would have missed the reason to travel all the way to Brazil if we didn't change for a better itinerary. The worst thing is that our baggage was missing for 4 days. We had no cloths for all this time, plus the aggravation to locate our baggage. Nobody knew where our baggage was. We ended up picking it up at the airport when they said that they will bring them home. Unfortunately our experience was very dissatisfied.
Lost luggage, people are not very nice to help you , I was just instructed to fill out a baggage claim online, they were not helpful when I had additional questions after I completed the form on my phone.
Staff in first class seemed to struggle to provide service to both sections. I didn’t get breakfast though I requested it. I only got coffee after asking the opposite side flight attendant and then could never see them to request a bottle of water.
My luggage was not sent with us. Not sure if this is Envoy Air responsibility but that was a very BAD experience
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.
Good crew and flight was on time. It’s a small plane with limited overhead luggage space. They said the overhead space was full and I had to check my bag. There was still space when I got on. Waiting for my checked luggage added 30 minutes to my trip. Not the end of the world but also not great.
Trip delayed for 2 hours because of rain. We boarded and have to get down the flight and reboard again.
No enough space plus only allowing one laggage instead of two like other airlines.
Qatar airways ,boarding arrangements at Hamid international airport could been better
Two flight changes before the scheduled flight. On the day of the flight, the flight was delayed, which caused the connecting flight to be missed. Then, I was directed to another airport (CUN) and traveled to Tulum. American gave a $12 voucher for lunch. The least expensive item on the menu at a Mexican restaurant was $9.99. Driving to Tulum was a bad auto crash, and traffic was delayed two-plus hours. The bottom line is that we should have been at the hotel at noon, but it ended up at 11:30 PM.
Miami lounges were overcrowded and we were unable to get in. We only had a short time. But the banks are too tight in all American hubs
Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.
