UA's level of customer service is explicitly horrible. I was on the line with UA service center for an hour after having manager on the line he just said things from script saying why this ticket is cancelled then hang up the call.
level of service is getting worse by day. if UA was not part of Star alliance there's no way I would fly with them. their hard ware and human resource is disgusting.
even on the flight crews look at you like so what do you want again from me , leave me alone attitudes .
