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

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.

I stupidly booked flights from London… I stupidly booked flights from London to LAX in March 2020, trusting that I'd be able to easily re-book. Well the pandemic hit and I converted my flights to 'future flight credit'. Can I book a new flight with these? - simple answer is no - at least not via the website and the phone is useless. United customer service is non-existent.

Awful Booking Process and Customer Service I haven't even flown with United yet, but so far they've made me re-book my flights 3 times, and there's still another 3 months before I fly. I booked a return flight to the US from the UK in January, I went on-line in March to check some details to find that my flights had been changed and my seat upgrades had been cancelled with no refund. So I re-upgraded and chose new seats, a month later I checked again, the flights had changed again, still no warning or refund, so yet another, re-select the seats and pay the upgrade fee again, 1 month later, same thing. Each time I re-upgrade my seats my bank charges me £1.50 for each transaction (United put each seat on each flight through individually from the US whereas the original booking was taken from the UK). In terms on transaction costs alone I'm down around £18, if you add to that the fact that not a single cancelled seat hasn't been refunded then it's around £250. I feel a small claims court action coming on.

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.
