Update: On October 25, 2012, Delta published a policy on delta.com clarifying the baggage check process for customers traveling on separate tickets. The publication stated that for travel on or after January 15, 2012, Delta policy would be to check a passenger’s baggage between the origin and destination points of a single or conjuncted ticket exclusively. Delta has since determined that it will postpone the implementation of the clarified policy in order to further assess implications, to better understand any applicable regulatory requirements, and to provide travel partners with additional time to evaluate potential adjustments to ticketing practices associated with such policy.
