Similar to Chase, Citi and Amex - CIT Bank has an offers section where they offer discounts to certain merchants. I saw offers for Avis, Budget, Albertsons, Fossil, 1800Flowers, Expedia and more. Worth checking your account if you have one to see your offers. Some notable travel offers;
10% off at Expedia (log on to see coupon code)
