Having experienced a few flight delays on my own, I'd like to know if there is some source of precise information about the delay (including up-to-date estimations of the delay and causes). So far it seems to me the only people who can actually inform about it is the air company staff, at the airport, and via oral announcements only.

I'd expect this information to be some sort of obligation, since compensations are related to the cause of the delay (if it's weather, it's OK for the company, otherwise the passengers have more rights, and so on), but I could not find a reliable source for this. At best, websites such as [FlightStats][1] indicate the estimated delay length, but never the cause (or probable cause).

Is this information available anywhere? I tried the airport's website and the flight company's website as well, but I couldn't find anything.

I see plenty of reasons why the company would not like to disclose this information, but I would expect some organism to enforce it.  

Besides, the fact that they currently inform the passengers only via oral announcements seems quite inefficient and prone to generate stress among the passengers (and extra work to ground staff, which is forced to repeat again and again the same information...).
