Now there's a customer friendly policy change. DL to allow SDCs for Premium Cabins without requiring the same fare class to be available. Effective today, March 18, 2014, Delta has modified its same-day confirmed travel program for customers ticketed in a premium cabin (BusinessElite, First or Business Class) for travel within the U.S. or for travel between the U.S., Canada, Puerto Rico and the U.S. Virgin Islands. For travel on or after March 18, 2014, Delta will allow customers to confirm a same-day change to their itinerary if there are seats available in the same premium cabin instead of requiring the same booking class as on the original ticket to be available. All other same-day confirmed program rules apply. There are no additional changes to the same-day confirmed program and no changes to the same-day standby program. Please note that the above policy change does not apply to tickets booked using Unlimited Complimentary Medallion Upgrades.

For complete SkyMiles program rules, please visit Membership Guide & Program Rules. Additional Information The same-day confirmed program and the same-day standby program are subject to change and the rules in effect on the date of travel will apply, regardless of the date of ticket purchase.
