I would assume that since CO owns a substantial stake in ORBITZ that one would acquire FF miles on any flights booked. I called OP service center and the agent told me that the only flights that don't count are Priceline, Hotwire, and some BULK FARES. I inquired specifically about ORBITZ and she said that as far as she could tell they WOULD count. I said "as far as you can tell" is not good enough - I wanted a definite answer, and she checked with a supervisor who said YES - ORBITZ tickets DO count.
