One of my flights today is oversold. When I checked it, I got a message asking if I wanted to VDB for $150, which I declined.

I am now looking at seat assignments and get a message stating that my ticket needs to be reissued.

I called UA and they said I was being rebooked because the flight was oversold.

Now, I am annoyed by this because I received no communication regarding what they did.
The good thing is, they put me on a direct flight so I will be home sooner.
The bad thing is, I will need to reorganize transportation at home, and had I left for the airport at my normal time, I would have missed the flight.

Bah...
