I flew into FLL from EWR on 1/1/17 and did in fact see the Delta 777 parked on the apron away from the gates, in the holding area off to the west. I was curious about it myself, but could not find any information about it online - until now. Air Canada Rouge does operate a daily 767 flight into FLL, and less than a month ago, Emirates began daily service from Dubai to FLL using a 777-200. A treat to see such a giant at a smaller (but growing) airport like FLL.
