I don’t do this commute with any regularity but I’ve done it more than a few times and I’ve spoken with a couple of pilots who regularly make this commute... From my understanding and experience it is completely hit or miss. Sometimes the flights are oversold by like 40 revenue standbys and you won’t get on and other times it will be way oversold and you will end up making it on. A couple I know who do make this commute rent a car and drive from time to time because it’s like $30 out the door. Not impossible but it’s a fair bet that almost any MIA or MCO commute from anywhere else in Florida is going to be tough.
