OAK-LAX-JFK (on the outbound portion of a $150 ticket)
JFK-LGB (on the outbound of another $150 ticket)
Was going to return the same way, but was bumped in LGB ($300) and ended up getting a nice agent to change my ticket so I just went home LAX-OAK instead. I was mistakenly credited miles for my return to JFK from LAX (where I'd been sent after I was bumped). I also called a customer service rep who gave me double miles for that, too, since I was missing out on the LGB promotion by going out of LAX.
