I was hoping someone here with more knowledge of the airplane industry than me (Al, maybe?) could answer a question I have about the availability of airplane tickets.
I've been searching different websites for several months now, for an open-jaw flight Seattle-Rome and Florence-Seattle for mid-November. I found a flight on Orbitz with near-perfect times & connections on Northwest/KLM going through Amsterdam. Due to the codeshare, they pop up as four available different combos. Recently, the same flight showed up on airfare.com for $799. However, if I try to book the tickets (on either site) I get the "due to inventory constantly changing, this fare is no longer available" and poof they go. I can't even get the (return) flight to come up directly on Northwest's site.
Are the tickets sold out? Not released yet? Is Orbitz/airfare.com just messing with my head? I'm asking mostly out of curiosity, since I've never had this situation occur before.
