Here are two:
CitiBusiness® / AAdvantage® Platinum Select® Mastercard® = 2X
AAdvantage® Aviator® World Elite Business Mastercard® = 2x
Cards with a general Travel category bonus should recognize rental cars:
EXAMPLES:
3x American Express Green
3x Chase Sapphire Reserve
2x Chase Sapphire Preferred
Thanks! This explains why I earned more miles with my Citi AA card than I expected (it's the Platinum Select version)
Did not think about rental cars coding as general travel. I used to have a CSP and an Amex Green but dumped both over the years.
