I'm not from Hipmunk but my guess is that yes, it affected them because they are sourcing their flight info from Orbitz. In fact, this is one of the reasons they probably struck a deal with ITA since that will give them access to pricing/availability without going through Orbitz. On the flip side, this probably means they will make no money on any flights referred to AA.com unless they have an agreement in place with them since before the AA pullout, they had been paid by Orbitz for the AA booking.
