Can you drive me between two Florida airports?

Yes, and it is one of the rides where booking ahead earns the most. A transfer between two airports is a long drive with a hard deadline at the far end, which is exactly the combination you do not want to hand to whoever happens to be at the kerb.

Miami, Fort Lauderdale and Palm Beach sit close enough together that this comes up constantly: a fare into one and a departure from another, or a cancelled connection that is faster to drive than to rebook. Orlando and Tampa are the same story over a longer distance.

Give both flight numbers. The arrival is tracked so the pickup moves with the aircraft, and the departure is what the drive is planned against, with the traffic at that hour accounted for rather than an average.

What nobody can do from here is tell you how long your bags and the border will take, and on this particular ride that is the number everything depends on. Your airline sets the check-in and bag-drop cutoffs at the far end; CBP's own published times cover passport control and explicitly exclude baggage and the walk out (U.S. Customs and Border Protection, n.d.). Tell the desk both flights and the plan is built around them, with the car waiting rather than the clock.
