Delta Air Lines this month introduced new checked-bag fees, including second-bag charges of $40 or $60 for economy-class passengers on many international routes.

Those fees, for travel booked as of Oct. 1 and flown beginning Oct. 15 or Nov. 1, depending on the market, affect those traveling between the United States and markets in Asia/Pacific, India, the Middle East and South and Central America. Routes to and from Brazil, Japan and the Philippines are excluded. Delta also introduced a $25 first-checked bag fee for Caribbean travel booked on or after Oct. 1 and beginning Nov. 1, excluding flights to and from the Dominican Republic, Guyana and Haiti. The carrier also raised to $40 from $30 the second-checked bag fee for travel between North America and the Caribbean and Mexico. Delta previously had instituted a second-checked bag fee for economy-class passengers traveling between the United States and Europe.
