Austrian Airlines, Air Berlin, Scandavian, Turkish. I think they're all part of the Star Alliance. If you count ALL airlines coming into MIA, the number is over 100. Pretty impressive.
Yes there was a clip on YouTube showing the landing of the A-380 in MIA. RE All Aboard Florida, there was an article posted somewhere that ticket sales are 16 or 17 months are in the future 16 or 17 months from now.
