Chase has brought back product changing on the United cards. A lot of people are interested in signing up for the various Chase United personal and business card given their recent increase in signup bonuses.
You can product change your annual-fee United card to the no-fee Gateway card. That should make you eligible again to signup for the card, assuming you have not received a card bonus on this card product in 24 months. (Note: there aren’t any fee-free Chase United business cards, only the personal Gateway card.)
This card product is available to you if you do not have this card and have not received a new Cardmember bonus for this card in the past 24 months.
It should be just a few days from when you product change a card until it clears out in the Chase system which will then allow you to apply again.
