Incredibly disappointed with United, again. My checked bag did not make it back and was sent on a different flight. Customer service at the baggage claim ensured it would be sent to my house by ten PM (on a Sunday night). Just received an email that it will be here at 230am, so I called explaining I needed many things in that bag for work but they could only say that it takes 6 hours to process and deliver. I could drive back to Chicago myself to pick up the bag that United lost in that time. Incredibly frustrating and they also do not reimburse for the original checked bag fee.
