Major credit card issuers have indicated they will waive late fee charges due to the disruption in the mail service caused by Tuesday’s tragic events in New York and Washington. Discover, MBNA, and Bank One are among the first to relax the policies regarding late fees. Discover announced late Thursday that it is eliminating all late fee charges effective immediately until normal mail service is restored. Discover Card said it is also providing additional assistance to its cardholders with special services including necessary emergency credit line increases and the issuance of replacement Discover Cards. MBNA and Bank One confirmed yesterday they will reverse late fees if customers call. However other issuers have indicated this morning they are reviewing the issue and may follow Discover’s decision to waive all late fees until full mail service resumes. CardWeb.com received a significant number of calls yesterday from consumers concerned about the impact of slow mail service on their credit card payments.
