Hey guys,

I'm an Australian passport holder who'll be tavelling to YYZ for less than 24 as part of a Mileage Run. I'm traveling from Frankfurt and will not be stopping in the US.

I was of the opinion that as an Aussie passport holder I didn't require a visa or have to advise anybody that I was coming. However when I just booked my flights on the AC website, its telling me

Your current flight itinerary includes travel to a country that requires additional passenger information.You are required to provide this information at the time of check-in.

To enjoy a quick and easy check-in process, we strongly encourage you to provide this information ahead of time from the comfort of your home or office with our secure online form.

Clicking on this link takes me to a page that says as I'll be entering the US I am required to notify AC of my address whilst staying in the US.??

Is this some sort of generic notice? Or do I have to enter these details? Seems strange.
