Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

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.

The plane was very warm the entire time, despite my vents being open. Additionally, we didn't have internet on our personal devices

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.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

Cramped seating for me. Luckily it wasn’t a long flight

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

Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats

They lost my bag and I still haven’t received it yet

The plane was old Only 3 bathrooms available for economy The entertainment was old and the selection was poor

Boarding was a disaster being moved by Air France by bus to the plane. The plane should have been at the right gate.

Flight was late over a hour just like the first one. WiFi was down.

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

They charge me for luggage which is was included on the ticket

Lost luggage, 2 bags were badly damaged and one of the bags came open.

Please serve no god if you must serve dog food

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

Awful. Delay after delay. And then again on the tarmac.

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

Food was not Good Nuts came very wet & not tasting Good Main course I asked for Steak they got me Chicken because they don’t have more !!!!

It cancelled and we were unable to catch our connecting international flights.

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

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.

All flight attendants could benefit by taking an international flight on Qantas Airline. Qantas attendants are much more hospitable in every way. Much superior than and attendants on any US airline.

Did not have enough time from Venice seaport at Ravenna to get to Venice airport in order to make the scheduled flights. Need to have at least 3+ hours from ship docking to airport.

The only negative aspect was turbulence, but that is out of the airline’s control. It was a great flight!

Our flight from Chicago to Des Moines was the problem flight due to a dismissive flight attendant. His conduct was unnecessary and unprofessional.. I will avoid using Americam Airlines again because of the situation. Very disappointing.

Mostly excellent. However, many too many gate changes. Connecting flight at ORD changed gate 6 times.

Mechanical issues and delays. I get it but bad experience. Turned my 3 hour airport experience into a 9 hours

The baggage process at the gate was terrible. Stay was not friendly at all

Flight was delayed because of mechanical. Could not get landing space which caused me to miss my connection. Messy and not organized.

We landed slightly early but then sat in holding area waiting for our gate to clear out for about an hour, so technically we arrived one hour late at the gate at ORD. The airport may be partially responsible here, but regardless of who is responsible, it was a bad experience to be so close yet unable to get off the plane.

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.

Left on time. Arrived early. Turbulence coming in and gate not open due to early arrival but expected.

Longer wait time at check in at Paris. No bridge to board flight , had to take bus and climb up stairs again to flight. Difficult for ones with back pain like me.

I was booked to travel from Dallas to Nairobi via Chicago and Brussels and had been issued boarding passes for all three segments of my journey. At the boarding gate in Dallas, I was required to check my carry-on luggage due to limited cabin space. Despite my attempts to explain that I was traveling internationally and would not have access to the bag during transit, my concerns were not considered. I also informed the staff that I did not have a padlock to secure the luggage, but this was disregarded. Consequently, I had to hastily transfer essential items from my carry-on into my handbag. To my surprise, upon arriving at Chicago Airport, I observed numerous international travelers boarding with cabin bags that were significantly larger than mine. This experience left me extremely disappointed and led me to decide against using United Airlines for future international travel, a sentiment I have also shared with friends and family. Unfortunately, the onboard experience on the Chicago to Brussels flight further reinforced my dissatisfaction. The cabin crew appeared disengaged, indifferent, and lacking in attentiveness, resulting in a service experience that fell well below my expectations.

I want to highlight the crew members and their excellent work and professionalism. They work hard to make a long trip the most comfortable as possible, the food and drinks they offer are pretty good. And they are always asking if you need something else. I have had experiences with other airlines where you have to basically beg for a bottle of water. This is not the case. Highly recommended!!!

the blanket was great and pillow helped. really need a toothpick packed with meals

Very comfortable plane. The food was very good (for airplane food). The crew was great

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

Everything could have been better. What needed to be wrong with United went wrong

It was good. The seats in economy weren’t bad

Very good. Comfortable and I felt well taken care of from start to finish

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.
