How Much Dry Ice Is Allowed in Checked Luggage?
Airlines and the FAA cap dry‑ice at 5.5 lbs (2.5 kg) por pasajero, and the bag must safely vent gas.
Packing more than that triggers cargo‑only rules, so weigh your slabs before heading to the airport. Most carriers mirror TSA limits but still require you to declare the shipment at check‑in. Travelers cooling food, medicamento, or research samples should measure net weight—not including the cooler—to stay compliant.
5.5 lbs Rule Explained
| Airline (2025) | Ice seco máximo | Label Required | Lo que significa para ti |
|---|---|---|---|
| Delta | 5.5 lbs | Sí | Standard limit—declare at desk |
| American | 5.5 lbs* | Sí | Higher limits only for medical cargo |
| Alaska | 5.5 lbs | Sí | Cooler must list “Dry Ice” & contents |
| IATA Int’l | 2.5 kg | Sí | Global baseline for most flights |
*Check airline medical‑exception policy if transporting vaccines.
Consejos prácticos
-
Pesar dos veces: Use a kitchen scale; exceed 5.5 lbs and you’ll repack at the counter.
-
Keep vent holes clear: Tape can block them and void approval.
-
Show labels upfront: Saves the agent digging into your bag.
Caso real: A biotech rep shipped samples on a JFK‑LAX red‑eye with 2.3 kg dry ice, declarado en check -en, and cleared TSA in under five minutes—zero delays.
What Packaging Rules Must You Follow?
Dry ice must be in a hard cooler or insulated bag that lets CO₂ gas escape and prevents pressure build‑up.
Vent lids or loosen screws slightly, then add a bright “DRY ICE – 2.5 kg or less” label plus contact info. Carry spares in case condensation weakens adhesive mid‑trip.
Etiquetado & Venting Checklist
-
“Dry Ice” or “Carbon Dioxide, Solid” in ≥ 0.25‑inch letters
-
Net weight in pounds or kilograms
-
Description of cooled item (“seafood,” “insulin,” etc.)
-
At least one vent hole or pressure‑relief valve
-
Airline approval sticker if provided at desk
Do You Need Airline Approval Every Time?
Sí. TSA grants final screening authority, but airlines decide what boards the aircraft. Pre‑notify via customer service chat or add a “special item” note to your booking record. Online check‑in rarely captures dry‑ice declarations, so arriving 10 minutes earlier avoids gate delays.
2025 Actualizaciones: Emerging Solutions for Cold‑Chain Travelers
The newest IATA DGR (66th edition) leaves quantity limits unchanged but adds QR‑code labels for faster baggage scanning. Some carriers now accept smart coolers that auto‑vent as pressure rises, a win for pharma reps on multi‑leg routes.

{#preguntas frecuentes}
Q1: Is dry ice allowed in carry‑on bags?
Only if the airline approves, quantity ≤ 5.5 lbs, and the package vents CO₂.
Q2: Can I combine gel packs and dry ice?
Sí. Keep gel packs fully frozen or they count as liquids at security.
Q3: Do I need a UN 1845 label?
Not for personal luggage under 2.5 kg; the plain “Dry Ice” label suffices.
Q4: What if my flight is international?
Most countries follow IATA’s 2.5 kg rule, but always confirm with your carrier.
