SMART BAGS ADVISORY
Effective Jan 15, 2018 Delta will not accept smart bags with non-removable lithium-ion batteries as carry-on or checked baggage on any Delta mainline or Delta Connection flight.
Customers checking a smart bag with a removable lithium-ion battery must remove it and take it with them into the cabin. Customers carrying-on a smart bag containing a removable lithium-ion battery must remove it from the designed enclosure prior to boarding the aircraft. Once the battery is removed from the bag’s designed enclosure, the battery may be placed inside the carry-on bag. The removable battery does not need to be carried separately from the smart baggage.
