Might we be able to come up with a consensus on the topicality of requests for reasons for delayed travel (esp. for compensation purposes)?
For an example, What caused the delay of DL49 AMS-JFK 08-08-2017?
I would ask for opinion on both a generalized question, or one that appears to be simple curiosity (what delayed this flight by 12 hours?) and a more specific question about delay which is explicitly for assistance with a claim for compensation (linked question is an example).
