Reliability of information

Hi all,

how reliable are the data provided by FA on their website?
I see more and more often that flights are not documented properly regarding flight timings.

Example is for today OS392
The flight should have been departed on 10:05, all major websites reported the delays properly, but on FA the flight was “scheduled on time” even if it was already 11:00
Only once the aircraft departed BCN the status changed to “en route, landing in 1h 52m”.

And this flight is just an example for flights which have delays. What are other sites doing different to get the proper data?
