Online Flight and Baggage Check-in @ delta.com

Delta.com, 4/2/2008 (excerpted)

Delta Air Lines customers now have more control of their travel experience with the ability to check in conveniently on delta.com for most international flights — right from the comfort of their home, office or anywhere they have online access. Customers departing the United States on international flights will save valuable time by printing boarding passes at delta.com, and proceeding directly to security when they arrive at the airport. Customers traveling with luggage can check-in bags simultaneously at delta.com, and make a quick stop at a Delta Baggage Drop location before heading to security.

Delta.com check-in is available for travel to any destination served by Delta that does not require the customer to hold a visa.  Customers can check in at delta.com up to 24 hours prior to departure using their SkyMiles number and PIN, a confirmation code, credit card, or electronic ticket number. Check-in must be completed at least 30 minutes prior to departure for travel within U.S. and no less than one hour prior to departure for international flights. Minimum check-in times may vary by airport; exceptions can be found on delta.com.
