So here is another example. I am trying to book BRU>PER via DOH on Qatar on September 13. Expert flyer says yes to D class:
But the OW website says no:
The full itinerary after PER is, surface to SYD then SYD>MEL>LAX>SEA>ORD>BOS>EWR>BRU. Maybe it is one of those screwing up the marriage but where the hell do I start to figure that out?
