✈️ Flight Guide: Dayton (DAY) → Miami (MIA)

September in Miami features several events that attract travelers and can affect airport crowds.

Labor Day weekend brings increased domestic travel and resort bookings, especially to Miami Beach, Fort Lauderdale, and the Florida Keys. Cultural festivals and university events at the University of Miami also add localized demand. If your trip coincides with these events, book flights and ground transfers early and expect higher occupancy and surges in rideshare prices during peak event times.
