It was great. I really love the app. User friendly and very comprehensive when it comes to having information at my fingertips tips related my travel.

Seat would not recline, and charger did not work. Person in front of me reclined before we took off and left it reclined when they got off the plane. Nobody ever told them to put their seat in upright position....which meant I was somewhat trapped in my window seat when deplaning. Another passenger had to go to their seat and un-recline so I could get out.

- delayed because video screens not working - delayed getting a gate at DCA Just continued bad experience IAH to DCA.

I couldn’t give an honest evaluation, because the Houston airport has a problem and I was stand up for several hours and after a long trip from Munich I feel really very tired

The experience was good overall; however, my United Airlines Mileage Plus Account didn't reflect my flights to Houston from Newark. In essence, my mileage rewards points do not reflect my actual travel. This should be corrected.

Good flight, even though there was a delay, still got back on time

First class flight crew was barely available. They came through 3 times while we were on the plane for nearly 4 hours.

It was partially ok .. not anything like from Orlando to Houston... first the flight attendant was not so nice and insisted on have a small backpack down when really was not to put in danger anyone, also the beverages they were not so good... not big chance to select other tea.. the seat was partially ok could not have those flips to hold your head.. and finally when it land off in Guadalajara, it was raining and the flight was going to the main area then go back and drop us out of nowhere with the rain.

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
