Always an issue I hade at least 5 hours of delays for a flight out of buffalo to newark. an aircraft never left and after switching my connection flight twice, was told it was being taken out of service. another plane was going to be sent from Chicago, to arrive after my last connection flight was scheduled. there way no way for me to get to any connection. I was set up with flight following day. we were an hour late getting off ground and we arrived in Washington fifteen min before my connection. I got off fast and shuttled to other side of airport and ran to gate. the flight was supposed to leave at 8:15a and I arrived to gate at 8:19 to find the plane left earlier than scheduled. now I'm stuck again for five hours before I can get home or continue to ny original destination. always have issues with United.

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.

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.

Never try calling their customer… Never try calling their customer service, they sound like robots they don't try to help you with the situation at all. They just repeat the same thing over and over again until your realize that they are completely useless. Horrible experience, will never use united again.

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.
