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.

Worst airline to travel Worst airline to travel. They will try to suck money out of you in every possible way. They charged me extra $50 for 2 bags that were allowed free to carry on by all other 5 airlines in the itinerary. Also they insisted again and again that the “kind of ticket class” I booked, they are doing me a favor for everything. I am not sure how they treat economy passengers but It felt insulting at one point. It was unfortunate that I booked tickets through united airlines. But I will not repeat this mistake again in future, it’s a lesson learned for me.

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.

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.
