3 hour delay. Had to change plans and was still delayed.

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Delays delays delays. Late taking off, late landing, wait for a gate, etc.

First time traveling on Southwest since bag fees were implemented. Usual good service. Just more expensive now.

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

Our first flight was so delayed that we had 10 mins to board the next one. We requested if the flight attendant could allow us off there plane first and they denied our request even though I have seen this done before. Luck was on our side that we didn’t miss our next flight.

Everything was great except for the in-flight wifi that wasn't working.

It was great! The new boeing has much more space and charging ports!

Took a little longer than normal, but the process is clear and easy to understand.

Baggage check in would have been better if the service clerk told the other clerk that she was merging her two long lines of customers with her line so she could move luggage. Instead she only told the customers. When I told the agent and ask if she could direct who is next in line so we weren’t trying to cut in front of each other she said it’s not her problem and she can’t work three lines. I was shocked. Understood that they were working more than their share but some organization so the customers aren’t getting upset at each other would have gone a long way

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

UA594 was delayed multiple times. I ended up getting picked up so I can make it in time for work 6AM on Monday, 7/6/2026

Both of my flights arrived early and check in process was smooth

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

Was a pain having to leave the plane and reboard but glad the plane was fixed

Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.

For a 22 minute flight all you expect is for it to be safe and comfortable

Lost connnection had to stayON in Chicago Was a mess

Booked economy through United - air canada treated it as standby and was almost refused boarding.
