I would personally be waiting for at least six months of relatively incident free operations. I totally accept that there are daily problems with many airlines and or airframes, but as a percentage, how many problems are we seeing compared to the total number in use? I also accept that it's a new type and that there can be glitches but these seem more than that to me.
I have some personal flying experience (only a PPL) and accept that there will always be risks. For me, for now, the odds aren't favouring the 787.
