Am an AC flyer who has been rebooked tomorrow on EDI-EWR-YOW -- EDI-EWR on UA, EWR-YOW on Porter. When I try to check in online it requires me to enter a contract tracing address in the US. There is no option to say I'm only connecting in Newark. Is this what I should be seeing? What I am supposed to put as the address?
thanks

Edit: now that this post has been moved to this thread, I see what to do.
