I'm still out 6 months before I ER at age 55, so I'm trying to foresee what types of things might change in the future. Presently I have no problems qualifying for/getting whatever happens to be the best rewards credit card at any moment in time. I also from time to time take advantage of various sign-up bonus offers (e.g. 50,000 miles, etc.). While I don't see myself going crazy doing "churning" I do see myself continuing to tweak which credit cards I have post retirement - closing some and opening others. Do retired people have issues getting the cards they want with smaller post retirement incomes and no active employer? Admittedly a bit questionable ethics-wise but what stops someone from listing their pre-retirement income and employer? I've never seen how those have been verified for credit card applications, and it would be consistent with the information already established with the credit reporting bureaus.
