Phx - ORD was nice 737 with starlink and the ORD - grr was ancient bare bones airbus with not even a power port lol

It was easy to board, and the staff was friendly and helpful. What could have been better is that I shouldn't have to pay extra for a seat that doesn't recline.

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.

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.

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.

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.

We were told our seats were switched which put us in row 1 instead of 12. We were not able to keep our personal items with us. This caused us not to be able to have our gum to pop our ears and we weren’t able to get our iPads out due to the seat belt sign never turning off.

Boarding was quick and efficient. My screen didn’t come on and everyone else had theirs working so a little bummer but it was a short flight!

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.

The amount of gate changes and delays is completely unacceptable. This has happened on 3 of 4 trips between Chicago and Dallas in 2026.

The delay update was very late. I had a stressful short connection and RAN through Chicago to get to the next flight, only to find the plane wasn't at the gate yet an nobody was boarding. I would not have had to run if the delay was updated earlier.

No flight delays. No need to rebook to make connections. Enjoyed second leg of flight on Iberia.

Same the delay was not ideal and the credits to move flights was not sufficient

No food on 4.5 hour flight, wi-fi did not work. Terrible experience for a long haul flight.

The plane was delayed after we boarded - although they sent an email to my work email (which I did not get until later) there was no announcement from the PA about the delay in flight. Fortunately, they made up the time in the air and we landed around the original time.

My luggage was not sent with us. Not sure if this is Envoy Air responsibility but that was a very BAD experience

The wifi experience is awful. I had to try again and again, taking over 30 minutes, to connect to the wifi. I had to watch the same two ads over and over until I was finally successful. Once connected, it was anything but "high speed" and disconnected at least three times during the flight.

This was the best 2 flights I have had with American out of SGF. Great crew both flights.

The CX617 from HK to BKK was delayed more than 1.5 hours.
