If you're on the fence about joining the Amex family, getting the Amex Green card is a solid place to start. It offers a competitive earning rate of 3x points on spending categories that include travel, restaurants, and transit. So if you aren't a full-time or regular traveler who would benefit from the luxury perks of its bigger brother, the Platinum Card® from American Express, and a majority of your spending falls into those categories, this could be a great option.
