Answering the basic question ... none at all, ever.
However, on occasions, sh 1t happens and you live with it or go into hyperventilation.
The only serious irrops recovery I've ever experienced have been with FlyBE [flew in a replacement aircraft after many hours] or BA during the 2010 strikes [which was superb].
I live in a world where things happen. I have learned to cope with it, for 60+ years.

Reason: Strikes and Ash were in 2010 ... I'm getting amnesiac.
