I must be particularly unlucky

I've had 5 IRROPs in the past few years: one was long haul (SIN to ZRH) and two were early morning flights (of which one was due to fog at LCY). The other two occasions (LH and LX) were admittedly late, intra-Europe flights, but both overnight and one made me miss half of Christmas!
To the OP - for your stats, I have on average I have an IRROP once every 30k. I don't count segments, but I fly an even mix of short and long haul on almost exclusively *A.
