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.

Great airline and the website is top notch. United isn't perfect but then again, what airline isn't? I was a faithful flyer based on my travel in a few destinations. Flew ~2-4 one ways each week for a few years. Always booked directly through the website. When you hit status, its great! Unlike some other airlines, they'll never leave a first class seat empty. They'll fill it with those that not only have the most segments, but highest revenue profile (from what I saw). It asks a few more questions than others (Southwest) but once you get into the groove of using it, you barely notice the extra clicks. Not a huge deal. Their mobile apps were sketchy back in 2011-2013 but the recent updates are great! Never hit a problem with it since ~2015.

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.

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.
