How to re-enable United Mileage Plus Explorer signup?
Good morning. I've been a United Mileage Plus Explorer holder since 2014. I'd like to re-enable the signup offer. Can I cancel and immediately re-apply? Is there a "cooling off" period? I don't want to upgrade to the Luxury card, but I know at various banks you can upgrade after 2 years and become eligible for the welcome offer. Thanks!!
