Delta to charge fliers for first bag

Delta Air Lines Inc., the last U.S. full-fare carrier without a fee to check a traveler’s first bag, will start charging $15 for the service as it works to boost revenue.

The move takes effect Dec. 5, Delta said. Checking a second bag will cost $25, half the current rate.

Atlanta-based Delta became the world’s largest carrier by closing its purchase of Northwest Airlines Corp. last week.

The fee reverses Delta’s earlier plan to keep the first bag free and is among its initial moves to match Northwest’s pricing for certain services.

Delta shares fell 80 cents, or 7.1%, to $10.48.
