| This flight was delayed by one hour or so, which made me miss subsequent flights Delta 0121 (MSP to HND) and China Eastern 0540 (HND to PVG). This delay caused me to change my subsequent flight to next day which caused a penalty of $1,187.90 that I had to pay to China Eastern. Also, when Delta booked me for the next day flight, they told me that my single piece of luggage will be in the same flight as me and that I should not be worried about it. Next day I came early to the airport and wanted to double check that my luggage is on-boarded with me in the same flight, to my surprise, I figured out that my piece of luggage was actually sent to Chicago and no one can explain why? I spent an hour with luggage service, at the end they told me that we are forwarding it to Shanghai and that it will be in Shanghai 8 hours before me, so, I was OK to just go to luggage service to pick it up once there. When I reached Shanghai, the luggage service could not even track it, China Eastern had no clue where it is. Next day I spend couple hours on the phone to try to figure out when can I receive my luggage but didnt get anything. I called then Delta luggage service, they told me that my luggage is still in Chicago and it is planned to go to HND next day then to PVG. After calling 2 to 3 times a day, finally I received my luggage 4 days since my original flight. I was on a business trip and my stop at Shanghai was primary for meetings scheduled for Saturday April 28th, due to delay, I missed these meeting and my stop at Shanghai become worthless. I couldnt make up for these meetings since Monday and Tuesday was a Holiday in China and I had to continue my trip to my next stop in Wuhan. The damage caused by this delayed flight and luggage is difficult to quantify beside the cash penalty that I paid ($1,187.90). I would like per this complaint to explain all the negative impact I went through due to a delay of a Delta flight.Resolution: Sugar coated email with 7500 bonus point. Total disrespect to customer.
