(MIAMI, FLORIDA) Miami International Airport (MIA) is trending again—this time for a viral claim that it’s “the worst airport in the world for lost-luggage,” with posts citing about 306 bags lost per million passengers. As of August 11, 2025, that claim is unverified. No official source has published a global airport ranking using that metric, and the United States’ primary dataset for baggage issues, DOT’s Air Travel Consumer Report (ATCR), does not rate airports worldwide. Instead, the ATCR ranks U.S. airlines by mishandled baggage per 100 checked bags. That difference matters For travelers trying to make sense of the headlines while planning trips through South Florida.
What Official U.S. Data Actually Measures
The ATCR, published monthly by the U.S. Department of Transportation, tracks mishandled baggage—lost, delayed, damaged, or pilfered—reported by airlines that operate in the United States. The key metric is mishandled bags per 100 enplaned checked bags, broken down by airline (both marketing and operating carriers).
- Airlines, not airports: Airports are not ranked in the ATCR; there is no “worst airport in the world” table in any recent issue.
- Normalization difference: ATCR uses per 100 checked bags, not per million passengers.
- U.S. focus: The ATCR covers U.S. operations and does not compare foreign airports or assign global superlatives.
Latest schedule: The ATCR’s most recent posting was July 9, 2025, continuing its monthly cadence.

The Viral “306 per Million” Number Lacks a Published Methodology
The social media post spreading on August 11, 2025 names Miami International Airport (MIA) and asserts a rate of about 306 lost bags per million passengers. The post does not link to a study, dataset, or method.
- There is no matching release on the DOT ATCR page or the Bureau of Transportation Statistics.
- Without a disclosed method, the figure can’t be validated or placed in context — for example, whether it counts:
- airline mishandling,
- TSA property complaints,
- insurance claims, or
- airport authority reports.
In short: there is no official confirmation that MIA is “the worst in the world” on lost luggage. It’s a viral claim, not a verified finding.
What Recent U.S. Studies Actually Found in 2025
Several media analyses this year used a different dataset: TSA property complaint records obtained via FOIA. Those studies compared U.S. airports by complaints per 100,000 passengers (not airline mishandled-bag rates, and not a global field).
- Highest complaint rates often appeared at:
- Orlando (MCO)
- New York JFK
- Palm Beach (PBI)
- Fort Lauderdale (FLL)
- San Francisco (SFO) ranked among the lowest complaint rates for large airports.
- Miami (MIA) was mentioned due to Florida’s busy hubs, but it was not identified as the worst within the U.S. by that method.
Key point: different datasets tell different stories. TSA complaints measure passenger reports to a security agency; ATCR measures airline mishandling; neither produces a global airport ranking. VisaVerge.com notes that while Florida airports feature prominently in complaint-based reviews, the current social claim about MIA being “worst in the world” is not backed by a primary study.
Why This Matters to Immigrants and International Flyers
Checked bags often contain more than clothing—especially for newcomers carrying vital documents, gifts, or cultural items. A lost-luggage episode can derail:
- a family visit,
- a job start date, or
- school enrollment.
Understanding responsibility and timelines helps protect your trip:
- Domestic U.S. flights: Airlines follow DOT rules on baggage liability and timelines. Claims must be prompt and documented.
- International flights: The Montreal Convention sets liability limits and deadlines for written notice. Receipts, photos, and time-stamped reports strengthen your case.
- Connections through busy hubs: High traffic can increase the chance of misrouted or delayed bags. Preparation reduces risk and speeds recovery.
Practical Steps if Your Bag Is Mishandled at MIA or Any U.S. Airport
You can’t control every variable, but you can lower risk and improve recovery chances.
- Use a tracker (AirTag/Tile) inside checked bags to help locate them quickly.
- Photograph your bag and contents before travel; keep serial numbers for electronics and a short packing list.
- Remove old baggage tags and stickers to avoid routing confusion.
- Arrive early for check-in; late-checked bags miss flights more often.
- Keep medications, keys, documents, and one day of clothes in carry-on—never check essential items.
- File a written Property Irregularity Report immediately at the baggage office; ask for a copy and reference number.
- Save receipts for emergency purchases; airlines may reimburse reasonable items during delays.
- Follow up in writing within set timelines. For international flights, submit written notice within Montreal Convention deadlines noted on your ticket.
- If valuables are missing, report pilferage to the airline and local police; keep copies of all reports.
- If the airline response stalls, escalate with a formal complaint to DOT for U.S. flights and keep all evidence organized.
How to Evaluate Future Claims About Lost Luggage at MIA
When the next graphic trends online, use this checklist before accepting conclusions:
- Is there a linked report with a clear method and sample period?
- Does the source use airline mishandled-bag rates (ATCR), TSA complaints, insurance claims, or airport authority data?
- Is the scope U.S.-only or global? If global, does it include comparable data for non-U.S. airports?
- Are numbers normalized (per 100 bags, per 100,000 passengers, etc.), and are they comparable across airports?
- Has the Miami-Dade Aviation Department or MIA issued a statement or published official statistics?
- Do reputable industry bodies—like IATA, ACI World, or SITA—support the conclusion?
Without these basics, treat sweeping “worst in the world” labels with caution.
What Officials and Industry Data Show Right Now
- No global airport ranking from the ATCR places MIA at the bottom; the ATCR remains an airline-based report.
- Prior 2025 press coverage using TSA complaint data highlighted MCO, JFK, PBI, and FLL at the top of complaint rates; MIA was not the worst by that U.S.-only measure.
- As of today, there’s no primary-source report matching the viral “306 per million” claim specific to Miami International Airport (MIA).
For travelers, the practical takeaway is steady: prepare smartly, document everything, and act fast if your bag doesn’t arrive. For policymakers and airport leaders, transparent, comparable data—shared with the public—builds trust far more than viral lists do.
This Article in a Nutshell
A viral August 11, 2025 claim that MIA is “worst” with 306 lost bags per million lacks published methodology. Official U.S. data (ATCR) measures airlines per 100 checked bags, while TSA complaints use different denominators. Travelers should document, track luggage, and follow airline or Montreal Convention claim rules promptly.
