I'm sure this probably qualifies as a "frequently-asked question" but I've not found an answer using Search...

Hypothetical example:

#1) Rate for city B to city C $400

#2) Rate for city A to C, with a connection in B $200

If you book the A-B-C option and don't fly the A-B segments, is there any hassle or penalty? In my case, I live by the City B airport and City A is a 2hr drive, so I'd rather skip that segment if possible (while still enjoying the lower rate).

Thanks in advance --
