Dunkin' (Open 24 Hours)
Finding it
Dunkin' (Open 24 Hours) is in 2nd Level Departures in Central Terminal at Miami International Airport. It sits landside, so you can reach it without a boarding pass — and you still have to clear security afterwards.
Central Terminal has 32 places to eat and 31 shops in this directory; the earliest opens at 4am.
Hours against the security queue
Across the week, MIA security runs longest around 5pm at a median of 16 minutes, and lightest around 11pm at 2 minutes.
Queue figures are medians from FlyIndex's MIA wait-time record, not a live reading.
About this location
This location sits pre-security on the 2nd level departures side of the Central Terminal, run on a 24-hour clock rather than the daytime hours posted elsewhere in the terminal. Being open around the clock puts it in reach of overnight staff, early arrivals and anyone waiting on someone through Concourse F outside normal service hours. It's grouped near Jackson Soul Food, QUORE Gelato and Skittles Remix, though none of those keep the same all-hours schedule. Landside placement means it's reachable without clearing the checkpoint, useful for meeting someone at baggage claim or killing time before a flight rather than mid-connection.
Other options in Central Terminal
All landside, so you can reach any of these before security.
