Is your Miami layover actually long enough?
Miami is the hub where a same-terminal connection can be worse than a terminal change, because Concourse D on its own is a mile long. It is also the one airport here that is ambiguous about whether its transfer route keeps you inside security, and we have resolved that ambiguity in your favour rather than ours.
Short by 15 minutes
You have 50 minutes after the delay. This connection needs about 65. Assume you will not make it, and read what your airline owes you below.
| 20m | Level 3 moving walkway between concourses | Miami International Airport, Flight Connections |
| 10m | Walk to and from the platform | our allowance |
| 20m | Security screening after a landside transfer | our allowance |
| 15m | Gate closes before departure | typical published gate cutoff |
| 65m | needed in total | |
This connection puts you through security again, which is the step that most often costs more than expected.
What American Airlines owes youArithmetic, not a prediction — we hold no data that would let us put a probability on your flight, so we do not pretend to. The gate cutoff is a typical published figure; confirm your airline’s. Your airline’s app knows your actual gates, which we do not.
If you have read otherwise
- The claim in circulation
- That Miami has a specific minimum connection time — commonly quoted as 45, 60 or 90 minutes depending on where you look — and that its concourses are all connected inside security.
- What is actually true
- Miami publishes neither. Its Flight Connections page gives 15 minutes for the Level 3 walkways between the North and South terminals and directs connecting passengers to screening checkpoints; it states no minimum connection time and does not say the North–South route stays airside. We therefore assume a screening queue for any concourse change, and show you the components rather than a single number.
- Where the confusion comes from
- Minimum connection times are filed by carriers and airports into IATA's SSIM and the OAG feed, which are licensed products. The figures circulating on the open web are extracts of that data, which is why they are stated confidently and disagree with each other — and why we will not republish one.

What MIA publishes, and what we assume
MIA is one horseshoe divided into concourses rather than separate terminals, which inverts the usual advice. Concourse D runs a mile end to end and MIA tells you to allow at least 30 minutes to walk it, or to use the Skytrain that runs above it — four stations a quarter-mile apart, trains roughly every three minutes. So “same terminal” at Miami is not the short hop it is at DFW or Houston, and a D-to-D connection deserves the same respect as a concourse change.
For a concourse change, MIA publishes 15 minutes on the Level 3 moving walkways between the North and South terminals. In the same breath it tells connecting passengers to get familiar with screening checkpoints, and nowhere that we can find does it state that the North–South route stays inside security. We have therefore built the arithmetic assuming you re-screen. If it turns out you do not, you arrive with time in hand, which is the only direction an honest estimate should be wrong in.
The Skytrain will not help you reach H or J. It runs inside Concourse D and solves the length of D — that is its whole job. American's international arrivals use the North Terminal arrivals facility, which also serves concourses E and F, and if you land at Concourse F you may be put on a courtesy trolley just to reach it.
- MIA publishes 15 minutes to move between the North and South terminals on the Level 3 walkways, and in the same place tells connecting passengers to get familiar with screening checkpoints. Because it does not state that this route stays inside security, our figures assume you re-screen. If you find otherwise on the day, you have time in hand rather than the reverse.
- Concourse D is a mile end to end. MIA says allow at least 30 minutes to walk it, or take the Skytrain, which runs above the concourse with four stations a quarter-mile apart and trains about every three minutes. A D-to-D connection here is not the short hop that a same-terminal connection is at DFW or IAH.
- American's international arrivals use the North Terminal international arrivals facility, which also serves concourses E and F. Arriving into Concourse F you may be put on a courtesy trolley to reach it.
- The Skytrain is inside Concourse D and does not cross concourses. It fixes the length of D; it does not help you reach H or J.
Every concourse pair at MIA, and what the transfer costs
MIA publishes one end-to-end figure that already covers its worst case, so every one of the 15 pairs below costs the same 50 minutes. That is what the airport states, and inventing a shorter number for neighbouring concourses to make the table look busier would be a guess dressed as a measurement.
Each figure is the published level 3 moving walkway time, plus a 10-minute allowance for reaching it and walking to the far gate — an allowance, because the airport does not publish that part and we do not pretend it does, plus the queue back through security, because this link leaves the secure area. Border formalities and your airline’s gate cutoff are added on top by the calculator above, since those belong to an itinerary rather than to a walk.
| Transfer | Allow | Re-screening |
|---|---|---|
| Concourse D to Concourse E | 50 min | Yes — landside link |
| Concourse D to Concourse F | 50 min | Yes — landside link |
| Concourse D to Concourse G | 50 min | Yes — landside link |

If you do misconnect, what your airline owes you
Start with the thing most articles get wrong: no US regulation requires an airline to give anyone a hotel. Searching for one in the rules turns up nothing, because it is not there.
What is there is better. 14 CFR § 259.5(a) requires every covered carrier to “adopt a Customer Service Plan … and adhere to the plan’s terms”, and § 259.5(b)(14) requires that plan to identify “the services it provides to mitigate passenger inconveniences resulting from flight cancellations and misconnections” — the word is in the regulation. So the demand is never “the law says you owe me a hotel”. It is “your own published plan says this, and the law requires you to keep to it”, which is narrower and much harder to refuse.
It applies only where the disruption was within the airline’s control — crew, maintenance, scheduling. Weather and air traffic control are outside it, and every plan below is scoped accordingly.
Read 14 CFR § 259.5| Airline | Hotel | Transport | Meals (3h+) | Rebook on another airline | Source |
|---|---|---|---|---|---|
| American Airlinesonly on request | Their plan | ||||
| Delta Air Lines | Their plan | ||||
| United Airlines | DOT dashboard | ||||
| Southwest Airlines | DOT dashboard |
Two ticks worth reading closely. American commits to these only on request, so nobody hands them to you — the letter below is that request. And Southwest is the one carrier here with no commitment to rebook you onto a different airline, because it holds no interline agreements; on a Southwest misconnection the next Southwest seat is the only seat, which makes its overnight commitments matter more rather than less. Verified 2026-07-29; we re-read these plans by 2027-01-29.
Hotel, meals and transport after a American Airlines misconnection
American Airlines delayed your inbound flight for a reason within its control, you missed your connection, and you are stuck overnight away from home.
Subject: 14 CFR § 259.5(a) — services due after a misconnection on [FLIGHT NUMBER], [CONFIRMATION CODE]
To whom it may concern,
On [FLIGHT DATE] I travelled on American Airlines flight [FLIGHT NUMBER], [ROUTE], under confirmation code [CONFIRMATION CODE] in the name [YOUR NAME]. That flight arrived late and I missed my connection on flight [MISSED FLIGHT NUMBER]. The reason given for the delay was: [REASON GIVEN]. On that reason the disruption was within your control rather than caused by weather or air traffic control.
14 CFR § 259.5(a) provides that each covered carrier "must adopt a Customer Service Plan ... and adhere to the plan's terms". 14 CFR § 259.5(b)(14) requires that plan to identify "the services it provides to mitigate passenger inconveniences resulting from flight cancellations and misconnections".
Your published Customer Service Plan states:
"A voucher for an approved hotel with available rooms if you are delayed overnight if you're away from your city of residence."
"Transportation to a hotel and back to the airport by hotel shuttle / third-party transportation service, or a transportation voucher."
"Meal vouchers if your delay is 3 or more hours after your scheduled departure."
I am requesting those services now. Specifically: hotel accommodation for the night I was delayed, ground transportation to and from that hotel, and the meal provision your plan describes. Your plan conditions these on a request being made. This letter is that request.
I note your plan excludes events beyond your control: "If the delay or cancellation is caused by events beyond our control (like weather), you are responsible for your own overnight accommodations, meals and incidental expenses." That exclusion does not reach this disruption, for the reason stated above.
Where I have already paid these costs myself, they are: [COSTS INCURRED]. I am requesting reimbursement of those amounts.
Please confirm in writing what you will provide, or your reason for declining. If you decline, I will file a complaint with the US Department of Transportation Aviation Consumer Protection Division, which enforces § 259.5(a).

[YOUR NAME]FAQ
MIA connections — common questions
Answers from what MIA and the carriers publish, with the source named so you can check it. This is not legal advice.
Is a 50-minute connection enough at MIA?
For a concourse change it is short. On our figures a North-to-South transfer needs about 65 minutes once you allow 20 minutes for the walkway at the top of MIA's published range, 10 minutes of walking either side, 20 minutes for security screening — which we assume, because MIA does not say the route is airside — and 15 minutes for the gate closing. That leaves you roughly a quarter of an hour short. Miami is the least forgiving of the four hubs here.
How long does it take to walk Concourse D at MIA?
MIA says allow at least 30 minutes, because the concourse is a mile from end to end. The Skytrain above it cuts that substantially, with four stations spaced a quarter-mile apart and trains about every three minutes, and our arithmetic allows 15 minutes for a same-concourse D connection using it. If the Skytrain is down, MIA's own 30-minute walking figure is the one to plan against.
Do you have to go through security again to change concourses at MIA?
MIA does not say clearly, and that is why we assume you do. Its Flight Connections page gives 15 minutes for the Level 3 walkways between the North and South terminals while also directing connecting passengers to screening checkpoints, and there is an airside connector between concourses D and E that does not obviously extend across the whole horseshoe. Where an airport is ambiguous we plan for the slower case, so our figures include a screening allowance for any concourse change. Confirm on the day, and treat any time you save as a bonus.
Where do international arrivals land at MIA?
At the North Terminal international arrivals facility, which serves American as MIA's hub carrier along with other airlines in concourses D, E and F. Arriving into Concourse F specifically, MIA notes you can take a courtesy trolley to reach that facility. All of this happens before any concourse transfer, so it adds to the arithmetic rather than replacing part of it.
Stuck on hold?
Talk to an independent agent instead
Airline phone queues and chatbots are where a rebooking stalls. Our agents work these routes daily and will look at what is actually available, walk through the letter you are about to send, and tell you what a desk agent will and will not do. We are not the airline and we do not file claims for you — the templates above are yours to send.
Other layover hubs
The arithmetic is the same everywhere; the airports are not. Each of these publishes different figures and hides a different trap.
