It’s about a 45 minute drive between FLL and MIA. A car service will run you around $130 to $150 and using Uber or Lyft will run you about $50.

Figure adding at least 20 minutes to deplane, exit the airport and get to your transportation, another 30 minutes to clear TSA at MIA and another 10 minutes to get to the departure gate. So a total of about 1 3/4 hours.

All that assumes your inbound flight arrives at the gate on-time, that’s are no traffic delays, and no backups at TSA. So even giving yourself 3 hours you’ll still won’t have much wiggle room.

I’m assuming you are considering doing this because you found a good airfare from your home airport to FLL but you have to ask yourself is the savings, after taking into account the cost of transportation between airports and the inconvenience you are causing yourself is worth it.
