Connecting at Miami: only two concourse pairs stay behind security

Last checked 30 September 2026

At Miami, America's biggest gateway to Latin America and the Caribbean, only two pairs of concourses connect without a second security line: D with E, and H with J. Every other combination means clearing security twice. MIA's own site doesn't state this outright — this is the best reading of the evidence available, so check before you rely on it.

At a glance

• Concourse D with Concourse E: connect inside security. A connection between these two is just a walk.
• Concourse H with Concourse J: also connect inside security.
• Every other concourse pair — including anything to or from F or G, and J to D, E, F or G — means leaving security and clearing it again. No reliable time figure exists for how long that actually takes.
• Arriving from abroad, connecting onward: you'll clear US Customs and Border Protection at Concourse D, E or J (F arrivals get shuttled to D), collect your bags first, then recheck them and go through security again.
• MIA's passport-control wait: half of passengers were through within 16 minutes; one passenger in ten waited about 46 minutes or more (GateCast estimate from US Customs and Border Protection wait data, Sep 2025 to Sep 2026).
• Moving between MIA's North and South sides takes about 15 minutes on foot — but that walkway is outside security, so it means clearing security again at the other end.

Six concourses, two pairs that appear to connect inside security

MIA has three terminals and six concourses: D, E, F, G, H and J. American Airlines is the dominant carrier, concentrated in Concourses D and E (D alone runs about a mile long), alongside Oneworld partners and several Caribbean and Latin American airlines in E. Delta sits mainly in Concourse H, Frontier in F. Other domestic carriers GateCast covers that fly to MIA are spread across Concourse G alongside smaller and regional airlines, so check your specific flight.

Only two concourse pairs connect without a second security check: D with E, and H with J. MIA's own site doesn't say this outright, but its screening reservations page assigns one shared checkpoint to each pair, and two third-party travel guides describe the same D–E and H–J connectivity directly — one of them adds that F and G specifically often work better reached by leaving security. MIA hasn't confirmed this outright — treat it as the best available reading until it's checked further. Every other combination — including Concourse J to D, E, F or G — means a real second security line, and nobody publishes a time figure for how long that takes, so don't assume a number.

Arriving internationally

Follow these steps in order.

1. Everyone arriving from abroad: international arrivals are processed through Concourse D, E or J, with US Customs and Border Protection. If you land at Concourse F, you're shuttled to Concourse D's international arrivals facility first. Go through passport control.
2. Everyone: collect your checked bags before clearing customs, then clear customs.
3. If you're connecting onward: recheck your bags and go through security again. This is the routine most international arrivals face at any major US hub.

Passport control at MIA: half of passengers were through within 16 minutes; one passenger in ten waited about 46 minutes or more (GateCast estimate from US Customs and Border Protection wait data, Sep 2025 to Sep 2026).

Tips

• D-to-E and H-to-J are the only concourse pairs that skip a second security line here. Any other combination, budget for a real security queue.
• Moving between MIA's North and South terminals is about a 15-minute walk, but it's outside security — you'll still clear a checkpoint again at the far end.
• Landing internationally, build in time for bag claim before customs, then the recheck and security line after it, on top of whatever the passport-control queue looks like that day.
