Stranded in Chicago and had to get a rental car, United never took responsibility United said I would be stranded in Chicago for 2 days, no hotel accommodations, sleep and hang out in the airport for 2 days. I had to be in KC for work, so I got a rental car and drove myself to KC. United declined to cover the rental car, and the whole experience was a disaster of customer service. Fly any other airline.

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.

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.

First Flight, Last Flight. Aside from the recent scandal United Airlines is literally the worst airline I've ever flown with. The only impressive this is how consistently bad they are at literally every area that constitutes a good flight experience. Incompetence like that takes dedication. Hats off to you United, I will never be flying with you again.

Worst airline to travel Worst airline to travel. They will try to suck money out of you in every possible way. They charged me extra $50 for 2 bags that were allowed free to carry on by all other 5 airlines in the itinerary. Also they insisted again and again that the “kind of ticket class” I booked, they are doing me a favor for everything. I am not sure how they treat economy passengers but It felt insulting at one point. It was unfortunate that I booked tickets through united airlines. But I will not repeat this mistake again in future, it’s a lesson learned for me.
