Baggage claim signs were not updated with my flight information, so I had to guess. The app wasn't updated either.

Baggage claim signs were not updated with my flight information, so I had to guess. The app wasn't updated either.

Read the fine print. This was my flight home. I booked my flight for the quickest way home. Had a carry-on and a personal item. Same as my outbound flight. Apparently I needed to pre-pay extra for my carry-on. When I checked in, I was told that I had to check it. I said I’ll pay for it, and was told that this wasn’t an option anymore. They said I still had to pay $50 to check my carry-on. I told them I’ll pay whatever to just carry it in as intended. I was not allowed, so eventually I paid $50 to check my carry-on under a plane that was half full, with overhead compartments that were even less full. My white carry-on suitcase was practically destroyed getting from Idaho falls to Denver to Orange County. The low price air fair was a bait and switch. Got me to the gate, made me pay extra, then didn’t even allow me to pay for a carry on. Not to mention that I paid the $8 for WiFi that didn’t work. All to get my suitcase destroyed. I don’t think I’m going to even keep my Untied mileage plus membership and card. Apparently, membership does not have its privileges for this one.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

Everything was great. Only thing that could’ve made it better was buy on board options for hot food, but the snacks were decent. The flight attendants were great. I had no complaints. I was able to make it to my destination safely

David went above and beyond to make our flight the best that it could be

The crew and flight was amazing. I haven't flown United in years but plan to switch to you being my main airline

Wouldn’t let me check in said couldn’t find a ticket had to wait very long Time

Seat cushions were worn down and it hurts as I seated under 5 hours of the plane ride.

I wish I had another choice. Domestic flight in the USA is atrocious.
