Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

Boarded early, left early, arrived 40 mins early! A win win for me!

I felt scammed. The priced advertised was different than what I paid. I paid the whole some online. I then got a call 20 minutes later saying I need to paid 70 more person. She said the price online is not the guaranteed price.

We had a delay, but thankfully I made it to my connection. Overall it went smooth

Left an hour and a half after the listed time. Up side was it had TV screens on the seat.

It's a long flight and I would have liked better snacks between lunch and the arrival meal. It's fine to have fruit and nuts but I really don't like ramen because it's salty junk soup. I'd suggest sandwiches. They're not expensive nor are they hard to store for a long flight. The FA's had a couple of big services and they were super busy preparing, executing and then cleaning up. Then they disappeared.

Great flight. Got to watch a movie. Smooth flight and early arrival at ORD.

I've been flying American mostly, and it's been very frustrating. This united flight makes me realize maybe the issue isn't flying, but the airline. United was a significantly better experience. The plane was more comfortable, with a normal amount of leg room (vs the ridiculous reductions AA has made), more comfortable seats, screens to watch movies. It was a much better experience!

We had excellent customer service despite the chaos at George Bush airport in Houston!

It isvvery small flight. No leg room . No space to put my personal item at feet.
