I currently have Chase United Explorer MileagePlus (opened in Oct 2021). I was planning to close this personal card in November but after second thought, it would be a good idea to downgrade it to United Gateway instead because in case I get approved for Chase United Business card in the near future, there's a deal where the cardholder gets 5,000 miles for also having a personal card open. I just wanted to confirm -- does the United Gateway also trigger the 5,000 miles for the Chase United Business card at anniversary?
