Customers are complaining about the website's search engine timing out, but it's obvious that the problem occurs when searching for an itinerary where at least one of the segments involves a discontinued route/market. Since many of the soon-to-be discontinued routes and markets are still viable for at least another month, it's probably a challenge.
They need to program the system so that instead of it searching endlessly and timing out, a message pops up that there is no service available for the XXX-XXX part of the itinerary, for the dates being searched.
