I reached 1MM UA status and am no longer chasing annual status, but still flying UA. I am leaning towards the Capital One Venture X card and waiting for a 90K miles bonus that comes every few months. In the meantime, I am either using my Fidelity Visa 2% cash back or old Capital One Venture card 1.25 miles/dollar.

Is there any reason for me to keep my Chase United Explorer card? I get better benefits and permanent Premier Gold/Star Gold except there can be Chase cardholder award inventory - not sure available to the UA Gateway Card. My mom switched her Explorer Card to the no fee Chase UA Gateway card (no annual fee) and back again. Does this show as continuing the same account open for good credit purposes?

My credit score is well above 800 so not really worried about opening a new card.
