The flight was delayed and passengers were told that they will miss connections as flight may get 40-55 min late.

I like Delta. I dislike the volume of announcements from the crew. They are not always easy to hear and typically repetitive.

Delayed 7 hours Crew and employees were nice Extra long flight but at least we got in

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

During the flight, the only refreshments provided were crackers and soft drinks; no substantial food was offered despite the international route. Furthermore, our initial flight was delayed, causing us to miss the connecting flight in Atlanta. The airline did not hold the connection, and we were informed that the next available flight is not for another 24 hours. While I am aware of alternative options via JetBlue, they operate out of JFK, which is not a viable solution for us as a resident of New Jersey.

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.

Requested for warm or hot water because of throat pain, it was denied. The entertainment system was hung, requested the crew to turn it off, instead of turning it off they rebooted the device. It was stuck again, no one bothered to check.

A couple flight attendants in business class had bad attitudes and provided poor service. They did provide drinks or refill drinks. They talked to certain passengers for long periods of time and ignored others.

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.

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.

They makes us feel confident on the flight. There was no any cancelation and they are really helpful with us.

Older plane. Food was really bad, almost not worth the effort. Huge difference with European based airlines.

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.

First time flying internationally with AA and probably my last. Not military friendly at all. Didn't allow free checked bag for military family members (dependents) on orders like other airlines. We were charged $100 for baggage weight overage (5 lbs!)even though we had military orders allowing us extra.. Didn’t allow military members to board early. Inefficient and long wait time to board. Seats are smaller and more uncomfortable than other airlines.. no drink service for over 7 hrs of flight! After initial meal was served, the crew never offered a snack or drinks until the breakfast's was served 1 1/2 hrs before landing. Overall expensive and poor experience for the entire flight.

Air was off while waiting on the runway and the temperatures became very uncomfortably hot. Flight attendants were very loud and rude the entire flight.

I booked tickets from San Diego to Cincinnati months in advance to attend my sister’s wedding, a wedding where I was serving as the officiant. At 10:00 PM the night before my 6:00 AM flight (just 8 hours before departure), I received an alert that my first leg to Denver was delayed, causing me to miss my connecting flight to Cincinnati. When I called Frontier customer service, they informed me that they couldn't get me on any other flight that would get me there in time for the Saturday wedding, let alone the rehearsal dinner. Because I had a critical role in the wedding, I was forced to buy a last-minute ticket on another airline for three times the original price, costing me well over $1,000 extra. Even with the emergency flight, I still missed the rehearsal dinner entirely. When I spoke with Frontier, they agreed to refund my original ticket, but showed zero care or accountability for the massive financial burden and distress they caused. Their "compensation" for causing me to spend an extra $1,000+ and miss an irreplaceable family event? A $75 Frontier voucher. Frontier completely dropped the ball. Their customer service showed zero empathy, and their reliability is non-existent. I will never fly Frontier again, and no one else should either if they actually need to get where they want to go. Tip for anyone flying from Denver to Cincinnati: Avoid Frontier connecting flights or layovers at all costs, especially for time-sensitive events. Book direct flights with an airline that actually offers reliable customer support and rebooking options when delays occur.

I will never fly Frontier again, and I strongly advise anyone who actually needs to arrive at their destination on time for an important event to book with literally any other airline.

Flight delayed and missed connection. Next available flight was a 10 hour delay.

It got me to my destination? However we were an hour delayed departing, and we never received any updates or notifications from staff. Poor communication and customer service.

Frontier didn’t give us enough notice that our flight had been delayed. I was just entering the airport when I received the notice, less than 2hrs before my scheduled flight. They delayed it 1hr 22min because another jet left late out of Vegas. Frontier needs better communication with customers because I could have eaten at home and had someone drive me instead of paying for an Uber.

Great flight, no problems. I wish they would increase the checked bag weight limit. Packing was very stressful.

Our flight was on time and unremarkable which I'm grateful for, as it is not the norm traveling these days. Frontier is a low-cost carrier and it really shows when compared to other "normal" carriers. They don't even give you water during the flight. The coach seats are decent, however it was not as clean as it should be. We had crumbs all over the floor by our seats.

I have come to accept Frontier as an absolute no-frills airline, paying for everything I want. A 4.5-hour flight should provide me with a complimentary beverage—rather, $4.9x for a soda. Or a bottle of water ought to be extended at no cost. 4 beers are on the menu, but only 1 type of beer is available (at $9.95). Also, so many restrictions to using a voucher from Barclay‘s Credit Card. Finally, try to reach a live agent for Frontier- impossible!

The ground crew in the Tampa airport were forcing people to pay for their personal items, although they met the measurement criteria. They receive $10 for each bag they charge passengers for so this is a complete fraud. An investigation needs to take place and the ground crew that does this need to pay the price, and the Airlines absolutely needs to make it right for these passengers.
