I understand that all airlines at T2 will be moving to the new T3 over the next few months. I have a 3-hour transit (without checked bags) through FRA on separate tickets this summer. While I'm hoping for an on-time arrival of LH's early morning shuttle from CPH to make AA's 11am departure to DFW, I was wondering if the new Skyline Train will connect Shengen-arrival gates at T1 to the new T3 gates?
