Well, personally I reckon there'd be more chance of you getting onto a delayed flight in general than getting involved in a car accident on your daily commute. But, I reckon there'd be a far more greater chance of you getting into a car accident on your way to work or wherever than falling out of the sky.
Btw, just noticed on the JQ website that whilst the upcoming 787 flight on the 13th is now $199, there's no sign of the return flight around 15:30, or whenever it was, that day. Has it been cancelled, or is it full up already? If it was full, would've thought it'd still show up but just as "not available".
For those who have booked the return flight with the price beat, have you received any emails about a cancellation, or perhaps it is the media flight and not aimed much at the public...
There is, however, another 787 flight returning on Friday 15th...
Edit: Yep, the return flight has been sold out, as confirmed by the price beat dude on the phone. Aaw, bummer! Something official going on with that one!
