Back in the 1970's and 1980's both Delta and Eastern had flights between FLL and MIA usually for market consolidation or aircraft positioning. Even had L1011's on this route. I was living down there then and one time flew FLL-MIA on EA to get my connection to NAS. I guess I could have just drove to the MIA airport but it was kind of neet to fly this route. The airports are so close landing at FLL from the west you can see aircraft landing and taking off at MIA.
