Well, it is a problem in that the services no longer exist. Each of the different inventory services have different details from different carriers. Losing out on Apollo or Worldspan when they had the best (or only) view of data for a specific carrier is an unfortunate development, even if there are still other tools out there with different data in them. Such is the risk taken when relying on other sources to provide data for which there is no guarantee of delivery. All of the other websites can change their feeds at any time. That's what happened here.
