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.

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.

Customer Service Just Hung Up on Me! RUDE 3am and i've called and waited in queue 3 times tonight. finally i get through. i complain about the terrible website of United Airlines and the 'customer service' agents hangs up on me!!!! Terrible airline to deal with. Terrible website to book tickets on. Impossible to find detailed and clearly stated information on cancel/refund policies. sadly, i have points to spend to be rid of United!! : (

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.

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.
