Missing Parts

As I anxiously await for my first leg of the trip to take off at from Kansas City to Los Angeles, I hear that there is a "part missing" from the plane and our flight is now DELAYED.

Some time later, all the passengers found out that the part is on its way from Milwaukee, but will not be arriving until at least 2:45pm.  This part also takes 3hrs to fix, apparently...  Meaning that my flight to L.A. will not actually be leaving until "some time between 6pm and 7:30pm with an arrival time around approximately 9:30pm."
That is, if the weather clears up.
My reaction: WHAT?!
My saving grace is the 12-hour layover that I scheduled to take in L.A.!  While I was supposed to arrive there by 11:20am,  I hope to now arrive with about two hours 'til by connecting flight to China.
Lesson Learned: Extended layovers are your friend.
