Original Post 8/18/21:
Chase is set to unveil a new feature when applying for a credit card. Customers that meet a certain criteria will be presented the option to reallocate existing credit lines when applying for a new credit card. Sometimes this is necessary to get approved for the new card as Chase has extended the maximum credit limit they feel comfortable with. Previously this had to be done via phone when calling the reconsideration department after a card was denied, this new system will be online and show as an option after applying.
