Have not had a flight out or returning to Norfolk that has not required maintenance, and a gate delay. Properly staff the crew so maintenance can be performed without last minute emergencies on each flight and there is enough staff to have gates prepared for inbound flights. Staff to ensure the safety and on time service vs. profit.

Staff to ensure the safety and on time service vs. profit.

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

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.

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

The seats on this flight weren’t as comfortable as we had expected. Even leaned back these seats left us feeling crappy in our backs. Also we had to use our own tablets for movies, but nothing in the seats in front of us to hold the tablets up.

It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.

Flight was delayed “due to earlier delays of that plane”, so we were nearly three hours late.

Both my flight where delayed Had 25min to make it to my transfer flight

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

We were delayed due to a mechanical issue, but the gate staff and then later captain were giving thorough and frequent updates. Ended up being delayed about an hour, but we did get out, so it was overall a good flight!

I was able to check into my flight through the app and online but had issues getting my boarding pass once I arrived to the airport.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

The flight attendants were very friendly, efficient, and helpful. The plane was ahead of schedule, and it all went very smoothly. Thank you.

I have a gluten allergy so did have any food

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Wonderful crew and early arrival to our destination. It was so nice to have free wifi access and movies too. Thank you!

Flight was delayed after boarding and no idea when it would take off. Crew in Portland did arrange for transport to Boston for a different set of flights to my destination.

Seats are so close together. Middle seats should be discounted.

I just for my TSA. So security line is short and upgraded to one group up. I do think the ground crew should learn new way of boarding - the passengers sitting in higher number seat should board first to prevent traffic jam.
