Within the past 2 months there has been a major influx of both MD-11s and 777s traveling to Florida, New York-Kenned, and other destinations. Between ATL & MCO there will be 5 777s doing round trips every day until September when the MD-11s are moved back to more domestic routes. Something even more amazing is the fact that the MD-11 is returning to Florida every once in awhile. Not since the MD-11 was first delivered has this ever happen. In conversations with pilots Delta is waiting on its China routes approvement before deciding on which 777 model to order.
