Really old place. Not as clean as it should be, tray tables needed better cleaning. The items, trays and some other items need to b6 engineered. Anything task you or crew may do is incredibly load, seriously engineer for quiet smooth, easy. Just opening and closing the tray table is actually dangerous and can easily injure a finger. I'm sure it happens as it happened to me! First time I used United and likely will be the last!

I’m an EP on AA every year for more than a decade but this was a very pleasant and surprising experience. Clean and sizable plane for HOU to CHI. 5 row first class. And excellent food in first class the steak option was really good. Your flight attendants even better. Seat 5A

The experience with United Airlines was excellent; however, the experience with Houston Intercontinental Airport (IAH) was horrible. Although our flight departed from Terminal B, we had to go through security in Terminal C and then get on a train for travel to Terminal B. Additionally, there was significant walking required to get to the boarding location.

Unbelievably smooth boarding at IAH and the flight attendants were top notch.

We flew business fares. Was amazing. However, the check in didn't offer business fares preboarding which is less hectic. 8/10 due to this. Staff compared to Canadian carriers go above and beyond. Would gladly fly United again.

Comfortable seating POS to IAH. Food options were satisfactory. Good seat from IAH to ANC. Food options could be better.

Always pretty good as far as I see it. Staff was friendly and process was quick to get on and off.

There could have been better food options in economy on the long 7hr trip from IAH to AM.

It was terribly delayed with zero support from united airlines. I reached at 1 am in the night. They did not provide any option to change the flights.

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

DFW notification of changing the gate notice was an inconvenience.

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

Platinum status. 65 people in the upgrades list. When everyone is special No one is

The flight was delayed multiple times due to the inbound flight arriving late, which is not a major issue. That being said, the boarding process was awful. The gate agent(s) didn't allow sufficient time for the pre-boarding passengers to get settled in and then called the four priority groups at the same time - i.e., called Group 1 and then called Groups 2-4 all at the same time. This approach had all four priority groups standing on the jet bridge from the airplane door to the gate end of the jetway for 10+ minutes in the heat (i.e., it was 96F outside and uncomfortably warm). This approach also made the actual boarding process a mess. There were multiple points of failure with the boarding process that turned a late departure into more of an issue.

Worst experience ever, extremely disorganized airline with super rude crew for first class passengers. I have submitted feedback to AA customer care online that this was my worst experience traveling in over 30 years

My flight attendant was miserable. Bathroom filthy and the water soapy in the tea. I’d choose delta everytime.

Nothing with the flight. It was good. Crew as very helpful especially fist class flight attendant.

I am generally an American Airlines loyalist but this flight was not good. I was seated in an aisle seat and the gentleman in front of my had his seat fully reclined which made it impossible to work on my laptop, eat or drink.. The gentleman in the middle seat was watching something on his phone without headphones.

Flight was smooth and on time: however, this flight was filled with advertising. We got it over the speaker system both when we took off and when we landed. Flight attendants were handing out sales flyers when we landed. It was not a good look.

The first leg of my trip from Dallas to CLT was smooth from check-in to landing. The snack, biscott cookie really needs an upgrade. Even if the upgrade is a choice of the cookie or pretzels.
