Long layover?
- With up to 3 hours between flights, MIA suggests staying inside: there are art exhibitions, shops and restaurants in the concourses.
- With 5 hours or more, you could visit an attraction or a shopping center outside the airport. Leave plenty of time to get back through security.
- Baggage storage is on the 2nd level of the Central Terminal (E), open 8 AM to 8 PM.
Stay safe
- MIA warns travelers to ignore ride offers from people inside the terminal. Soliciting rides there is illegal, and those drivers are often unlicensed and uninsured.
- Get rides only at the marked taxi stands and rideshare zones. Uniformed airport staff at the lower-level curb can help.
- Keep your bags with you at all times, including at the curb.
