Delta Air Lines Inc.  passengers flying economy on international flights will now get free beer and wine, a perk resulting from Delta’s merger with Northwest Airlines Corp. last year. On flights longer than 3,800 miles, economy class passengers will also get a hot breakfast.

Northwest already offered free beer and wine for economy passengers on those international flights, said Delta spokesman Kent Landers.
