There was no internet on the flight. As an executive flying during prime business hours, having internet is critical for a smooth experience. This impacted productivity and time that will need to be spent later to do the work I could have done on flight.

There was no internet on the flight. As an executive flying during prime business hours, having internet is critical for a smooth experience. This impacted productivity and time that will need to be spent later to do the work I could have done on flight.

They took us all the way to Monterrey to tell us they United were not allowed to land and we were sent back to Houston. Terrible experience.

Great flight and crew. Need more legroom and DO NOT allow seats to recline.

I dont like to buy ticket type no carry on because I can have along with me my personal stuff like computer, headphones etc etc

Flight was very smooth from Boston. But when we got to Houston, the gate was not open and we waited on the runway for over 30 min!!

It was very good. the food was varied and tasty, the movie was the same, maybe I would recommend changing the movie selection every month because my flight to Amsterdam was in September and I came back from Munich en October they are flights so long and we need something to see. But however I liked flying with United

Flight attendants need to know their plane. Seated in first row yesterday. The seat had about a 1 inch recline that was not adjustable. I don't appreciate being awakened to raise a seat that can't go any further forward and such a small recline is either irrelevant or the plane needs to be repaired. Not the way to treat any customer and especially the ones who have paid that level of money for the seats.

Flights was great, service and transit support was outstanding - but the food was limited and of poor quality - only a snack on the first hour for 2 hours 1/2 leg. and a light breakfast on the second 4 hour leg.

typical but they have finally enhanced the wifi on some UA flights. Boy, its such a huge improvement

I like the first class seat amenities like the phone charger on the armrest even though it didnt really work on mine and the partition between the seats. I also liked that there were additional places to stash things during the flight. The food I got was steak and it was really tough to cut with the knife. Chewy too. A little disappointed in that. I liked that your name is on the screen too. nice touch. great service overall.
