Staff have a bad and unhelpful attitude I had a flight booked from heathrow to cancun which went via Houston. The staff were unhelpful and rude they were more interested in feeding themselves.when we got to Houston for an internal transit it took two hours to get through passport control and almost missed the connecting flight.

They need to do better Their level of service and quality of product need to improve. They can't rely on a business model that everyone else is using and perform worse than their competitors. They either need to develop better products and services, provide more value for customers, or else. Horrible experience on my last trip. They cancelled my return ticket saying that I was a no-show for the outbound flight although I sat in my seat in the outbound flight and even gate-checked a bag. They wasted more than two hours of my valuable time during my trip and caused a lot of stress. They didn't even know how this happened. No one apologized to me for their mistakes as of date. Their agents thought I was lying or I was the one who made the mistake. Incredible.

Our flight was cancelled after sitting… Our flight was cancelled after sitting 8 hours at Newark Airport due to plane issues. United could not get us out on another flight for 2 days. We had to drive 8 hours home that night because we had to be home. The issue is they would not reimburse us for our car rental to get home. They offered us vouchers. Why would we spend more money with someone who does not take care of their customers. Our request was for an expense far cheaper than staying in Newark for 2 days. Never again with United. First and last experience

Baggage was delayed and they closed my… Baggage was delayed and they closed my case after I got the baggage. They dont answer because of interim expensives. Really bad airline. Dont book.

First Flight, Last Flight. Aside from the recent scandal United Airlines is literally the worst airline I've ever flown with. The only impressive this is how consistently bad they are at literally every area that constitutes a good flight experience. Incompetence like that takes dedication. Hats off to you United, I will never be flying with you again.
