thank you guys...
based on your responses, seems like it's a too risky. the repricing could be a good idea only if you are lucky enough to talk to a nice agent.
I think I'm going to book EWR-SJC and SJC-ALB, at least that should get me half of the savings! BTW, this is a non-refundable ticket, very cheap, reason why I'm going... $123 + taxes!!!
