Question 1, I checked the Sydney internet site and it appears that there is a bus that goes between terminals. Also, I see on the airport map that the train stops at both terminals. Further, Virgin Australia seems to have a transfer site.
How do we expeditiously go from Terminal 1 to 2?
Question 2, DW has her flight booked all the way from the USA to Perth, since I purchased her ticket. I used frequent flyer miles and my ticket on Delta ends at Sydney. I had to purchase my flight from Sydney to Perth on the internet with VA. I realize that we will be going through customs and taking our luggage. When entering the USA, we usually are able to hand the luggage back after custom and not have to handle our bags.
Since my travel is made with two separate tickets. How will I deal with my luggage in Sydney? Will I accept the luggage after customs, then check it at Terminal 1, or have to carry it to Terminal 2, where I check it?
