JetBlue allows lithium batteries in carry-on bags but prohibits them in checked luggage. Passengers can bring consumer electronics with lithium-ion batteries (up to 100 watt-hours) and up to two spare lithium metal batteries (up to 2 grams of lithium each). Larger batteries, like those over 160 watt-hours for mobility devices, require airline approval. Proper packaging to prevent short circuits is mandatory.

How Does JetBlue Classify Permitted Lithium Batteries?
JetBlue categorizes permitted lithium batteries into two types: lithium-ion (rechargeable) and lithium metal (non-rechargeable). Lithium-ion batteries must not exceed 100 watt-hours, while lithium metal batteries are capped at 2 grams of lithium content per battery. Devices like smartphones, laptops, and cameras fall under these guidelines. Spare batteries must be individually protected to avoid contact with metal objects.
The distinction between battery types is critical for safety. Lithium-ion batteries are common in modern electronics due to their high energy density, but they carry a higher risk of thermal runaway if damaged. Lithium metal batteries, often used in watches or medical devices, are more stable but still require careful handling. JetBlue’s classification system helps crew members quickly identify potential risks during security screenings. Passengers should note that power tools with removable lithium-ion batteries exceeding 100Wh require special authorization, even if the tool itself is packed in checked luggage.

Why Are Lithium Batteries Restricted to Carry-On Luggage?
Lithium batteries pose fire risks if damaged or short-circuited. In carry-on bags, cabin crew can quickly address incidents, whereas checked luggage lacks immediate monitoring. The FAA mandates this rule to mitigate in-flight hazards. JetBlue enforces this by scanning checked bags and removing improperly stored batteries, which may delay luggage delivery.
What Are JetBlue’s Rules for Spare Lithium Batteries?
Spare lithium batteries must be carried in original packaging or insulated with tape over terminals. Passengers can bring unlimited lithium-ion spares under 100 watt-hours but only two lithium metal spares under 2 grams each. Batteries in checked baggage—even inside devices—are prohibited. JetBlue reserves the right to confiscate non-compliant batteries at security checkpoints.
How Does JetBlue Handle Larger Lithium Batteries for Medical Devices?
Batteries over 100-160 watt-hours for medical equipment (e.g., CPAP machines) require prior approval. Passengers must notify JetBlue at least 48 hours before departure and secure the battery in a rigid, leak-proof case. Crew members may inspect the setup pre-boarding. Batteries exceeding 160 watt-hours are generally banned unless certified by the FAA or IATA.
How Do JetBlue’s Lithium Battery Rules Compare to Other Airlines?
JetBlue’s policy aligns with major U.S. carriers like Delta and American Airlines but is stricter on spare lithium metal batteries (capping at two vs. Delta’s allowance of up to eight). Unlike Southwest, JetBlue doesn’t permit loose batteries in checked baggage under any circumstances. International carriers, such as Emirates, often enforce lower watt-hour limits for non-approved devices.
The table below highlights key differences:
| Airline | Lithium-Ion Limit | Spare Lithium Metal Limit | Checked Baggage Policy |
|---|---|---|---|
| JetBlue | 100Wh | 2 batteries | Prohibited |
| Delta | 100Wh | 8 batteries | Allowed in devices only |
| Emirates | 160Wh | 4 batteries | Restricted by device type |
“JetBlue’s lithium battery policy reflects industry-wide efforts to balance passenger convenience with aviation safety. Their emphasis on carry-only storage and terminal insulation aligns with IATA’s 2023 guidelines. However, the two-battery cap for lithium metal spares is more conservative—likely a precaution against thermal runaway clusters in crowded cabins.” — Aviation Safety Consultant, Michael Torres
FAQs
- Can I Bring a Power Bank on a JetBlue Flight?
- Yes, power banks up to 100 watt-hours are allowed in carry-ons. Those between 101-160 watt-hours require airline approval. Label the power bank with its watt-hour rating for faster security checks.
- Are E-Cigarettes Allowed on JetBlue?
- E-cigarettes with lithium batteries must be in carry-ons. Usage or charging mid-flight is prohibited. Spare vape batteries follow the same rules as lithium-ion batteries.
- Does JetBlue Allow Lithium Batteries in Checked Bags?
- No. All lithium batteries, including those inside devices, must stay in carry-ons. JetBlue scans checked bags and removes non-compliant batteries, which may delay luggage delivery.
