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.

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.

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.

Shockingly bad from start to finish Shockingly bad from start to finish. Rude cabin crew, appalling lack of any service and fithly unattended bathrooms on-board, capped off with 1.5 hours sitting on the Newark tarmac waiting to disembark. "Fly the friendly skies" must be the most ironic slogan in all advertising history.
