I have the MileagePlus Explorer Card. My AF posted on Jan 1. I am thinking of asking for a retention offer and then cancelling if not offered. I have Elite Status for 2021 so I don't need the benefits of the Explorer card such as boarding priority or free bags. Two questions: (1) If I say that I am thinking of cancelling and want a retention offer will I be able to cancel the cancellation if I decide not to proceed while on the phone (am I stuck with the cancellation if I just ask?). (2) Can I get this card again in the future (2022) if I cancel now? As my elite status lasts until Feb 2022.
