The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

The flight was delayed, they didn’t even have water for the toilets or for drinks

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

The flight had a delay but I made it to my connection. Flight was smooth overall

The flight to Houston the agents were not very helpful

Horrible, absolutely horrible. The airline overbooked the flight, did NOT assign seats and boarding was a hot mess with lots of confused passengers. There was no "large plane" gate for us, the 500+ passengers were squeezed in a small hold room area, and multiple busses had to shuttle us to the other side of the airfield, where boarding of the plane, that was parked on the ramp, took place in rain. The old plane had a broken seat, that the technicians tried to fix - with no success - resulting in a 50min delay. The flight attendant with heart shaped earnings with German flag was screaming on the passengers without a reason, was extremely rude and entitled the entire flight. The food was junk. I hope I don't have to fly United ever again.

No screens or meal options. Freezing cold. Dirty seats. Left late.

It was terrible. sat on airplane 2 hours then flight was canceled. made to pick up bags and go through Panama immagration to rebook another flight. worst experice ever at a airport.

Good but airlines getting smaller. I didn't like the meal but the service was fine. Flight was fine and luggage arrived. So good.

Lounges are packed and very poor, food is really bad, for business class in an airline is well below expectations
