Delta will check a customer's baggage between the origin and destination airports that are issued on a single or conjuncted* ticket exclusively. When issued on one ticket, Delta will also continue to check baggage through to the ticketed destination for interline itineraries.  If a second ticket is presented for travel, Delta will only check the bag to the destination of the Delta ticket(s). Baggage may be claimed at the Delta-ticketed destination, and then re-checked by the customer with the downline carrier for the next flight.

* A single ticket also means a conjuncted (i.e., conjunctive) ticket. Conjuncted tickets are sequential in number on same ticket stock.  It is not possible to conjunct tickets from different airlines.

 Travel Agency Information

Delta recommends creating a single ticket instead of split ticketing as a general best practice to ensure that Delta will be able to check baggage to a customer's final destination.

If a travel agent issues a multiple-ticket itinerary, the issuing agency must:

• Inform the customer to claim and recheck baggage if a customer's itinerary is issued on multiple tickets.
• Inform the customer of passport and/or visa requirements in cases where they must collect their baggage and recheck the baggage with OAL.
• Ensure that the itinerary booked allows customers sufficient time to claim and recheck baggage. Please note: When separate tickets are issued, it may result in misconnects. Minimum connection times (MCT) in a GDS apply only when an itinerary is sold as a connection, not when flights are sold by flight segment. 
• Inform the customer that Delta is not responsible for missed connections including flight irregularities or delays that result in a missed connection to a flight that is ticketed separately.

 Single-ticket and Multi-ticket Examples

Single ticket example:

• Ticket 1 - ATL-LAX on a Delta flight connecting to another airline operating LAX-NRT.

Delta Policy: Delta will check the baggage from ATL to LAX to NRT.

Multi-ticket examples:

• Ticket 1 – ATL-BOG on a Delta flight
• Ticket 2 – BOG-SCL on LATAM (LA) Delta partner airline (see list above)

Delta Policy:  Delta will check the baggage from ATL to BOG to SCL.  Baggage allowance and fees will be calculated from ATL to SCL. 

• Ticket 1 – ATL-LAX on a Delta flight
• Ticket 2 – LAX-NRT on a different airline (OAL)

Delta policy: Delta will check the baggage for the ATL to LAX flight only.  Upon the flight’s arrival at LAX, the customer will then need to collect the baggage at the Delta baggage claim and then proceed to check it with the down-line carrier for the next flight LAX to NRT.
