I'm of mixed feelings on this.
Currently the information is very spread out and so putting it all in a single forum could be useful. On the other hand, the implementation and execution of EU261 is often airline specific (e.g., how do I apply for EU261 from Delta? does it apply if I'm ex-US, etc., etc.).
I wonder if it makes sense to combine the existing ad-hoc threads in each major airline forum and create a master 'sticky' thread that sits at the top of each major airline forum but is specific to the airline because ultimately at the end of the day, what I care about most is: if I'm flying airline X and have a delay or cancellation, how do I file a claim with airline X, how has airline X generally responded to these claims, etc., etc. -- and if it turns into case law and corner cases, FT isn't going to be able to solve those issues for me
