Delta Air Lines is charging many customers $15 to check a first bag and $25 to check a second bag, "consistent with Northwest's existing policies

." Delta officially acquired Northwest Airlines last week and is in the process of merging it into its own operations. Delta determined that "customers are not differentiating Delta as the only major airline not charging for a first checked bag." Also consistent with Northwest's policies, Delta now offers customers the ability to pay an extra fee of between $5 and $25 to reserve bulkhead, exit row or forward-cabin seats. Other aspects of the carriers' "alignment of policies and fees" affect phone reservations fees, loyalty program award redemption and curbside check-in fees.
