Interestingly, my SO was booked SNA-DEN-CCC for this morning - partly to avoid potential weather in ORD, only to have SNA-DEN canceled, and auto re-booked thru ORD (in Y, so COS bonus expected ^). I noticed a few other So Cal-DEN flights for today were also cancelled.

So far, so good...but of course you never know until you touch down at your final destination.
