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.

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.

United is costing me $244 I won't forget On my way back from a business travel from Denver CO to London UK I had to pay a fortune to select one of the few row seats still available, because I like to be able to stand up and go to the toilet without bothering anybody to let me through. When I try to locate the past trip and get the receipt for the seat selection, United website simply throws a series of schizophrenic errors. Finding past trips? Impossible to do so using the confirmation number and last name. It doesn't matter if confirmation number meets criteria, or if I enter the last name exactly the way it is spelled in the ticket, it doesn't find it. Finding receipts? The website finds none, not even of the entire flight ticket.

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.

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.
