Whom would you discuss or write to at UA and what consideration would you ask for if something like the following happened:
1-Baggage loading truck hits our plane's engine. Flight is cancelled.
2-Agent tells us to go to Red Carpet Club and wait for rescheduling info. We take all of our belongings and go to RCC and arrive to the door before 6 PM. The sign on the RCC says open until 9:30 PM. However the RCC is closed.
3-UA finds an other plane and reschedules flight for 3 hour and 20 minutes later.
4-We load new plane.
5-New plane is delayed because air conditioning is not working and needs to be repaired.
5-After an additional hour delay we take off.
6-On new plane our seat is broken.
7-All of the overhead lights are broken-so all night they keep entire ceiling lights on.
8-Speaker system in our chair is not working.
9-Special meal ordered is not found.
10- At the end of the flight Flight Attendant tells us that the special meals were there, but someone else “ate them.“
11- None of our luggage does arrives with our flight.
12-Of course, missed our arriving connections to business meetings scheduled several weeks ago.
13- Due to the delays caused by the mechanical problems and the non arrival of our luggage on our flight, we incurred substantial extra transportation/ phone/ food, etc expenses.

Thank you for your ideas and suggestions.
