I'm in a quandary. I accept the arguement that all aircraft have teething problems. I'm also one of those people who will argue with people who claim air travel is unsafe; it is incredibly safe on every measure.
But I do have my own, internal, risk assessment. I've said before there are airlines I would avoid if possible. But the problem comes when I'm in the home country of an airline I want to avoid and the choice is between flying with them or going by road. Given the level of road accidents in most countries I'll fly. When TWA started 767s over the Atlantic I was invited to Kansas City and they suggested using the 767 and I declined; we went via Chicago on 747s. Nowadays I don't think twice about EROPs on twins.
So, the 787. I think I'll avoid it when booking, if I can, for the time being. If a schedule change puts me on a 787 that's fine. I do have some (laymans) reservations about the battery fix. Somehow the idea of accepting a fire might occur and containing it rather than stopping the cause worries me. But then fires do occur in the cargo hold despite all the precautions and banned items the solution is to try and put it out - contain it, in effect. Daft eh?!
