Can't get as far as the questions as we are not travelling until November. Looks like you can only get further than the initial sign-in until three days before travel. I was hoping to see the questions well in advance so I would know that the trip is not possible well in advance of three days before. I would guess that the process and the questions will change by Nov, so I guess I'll wait until mid-Oct and start thread asking for help.
November? Lots WILL happen between now and then.... Keep aware of the changes and by mid-October you should have a good idea of what's what.
