My previous company had Amex Gold, which I usually redeemed the points for Home Depot GCs. New company does not have a company card, so I have to apply for one. My wife and I like to travel, so we want to use points for future vacations. With my business, I will be flying mostly Delta, while occasionally American and USAir. Also, I will stay in Hilton properties 75% of the time and Marriott 25%. SO.....THANK YOU for your recommendations on which card will earn us the most points for future travel.
