Does anybody know if the prices on dates that have already been released are affected when new dates are released? In my case, I'm looking to book April 30-May 6 out of RDU. Up until last week there was an internet one-way fare offered as the cheapest rate, then last week that rate no longer showed up and hasn't since. I've been holding out for a DING! but am starting to get antsy about waiting much longer. Now I'm wondering if the release of new dates would have any affect on the fares for my dates? Any experience w/ that?
