They need to do better Their level of service and quality of product need to improve. They can't rely on a business model that everyone else is using and perform worse than their competitors. They either need to develop better products and services, provide more value for customers, or else. Horrible experience on my last trip. They cancelled my return ticket saying that I was a no-show for the outbound flight although I sat in my seat in the outbound flight and even gate-checked a bag. They wasted more than two hours of my valuable time during my trip and caused a lot of stress. They didn't even know how this happened. No one apologized to me for their mistakes as of date. Their agents thought I was lying or I was the one who made the mistake. Incredible.

Absolutely horrible experience Absolutely horrible experience. Been in Quito for 2 days now without my bags, after being told our bags were on the flight last night heading to Quito we find out they have not even left Houston. Been on the phone all day and we still have not gotten a decent answer to where or when our bags will arrive. United you are the worst airline and we will never book with you again.

Terrible service for premium Polaris… Terrible service for premium Polaris price. ORD to LHR for over $6000. Seat changed twice due to aircraft changes, they claim. Seems to me it’s not rocket science to have an algorithm that maintains seating choices and preferences when aircrafts change? Bag drop off also a pain. Then to the Polaris longe seated lunch? No spaces available, sorry. Terrible all around. Waste of money. Premium price for ordinary service or even poorer.

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.
