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.

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

Fraud of Refund Voucher Around 6 months ago, I was forced to cancel a family flight and received a voucher number to get a discount to book a new flight. The new flight booking is not accepting the voucher code. The costumer support made the booking manually and received the same error and requested to change the voucher into a discount code. The answer from the CS team is that a refund is impossible. I corrected them saying the other CS requested a discount code, not a refund. The Email bounces back. No answer given. I was in 49 countries in around 200 flights globally with endless of flying companies. But united was one out of two (Turcish Airlines second) which is involved in unfunctional service that causes fraud.

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.
