The American Express Green card is a very often overlooked card, but can be a very powerful card. It can be a very beneficial card to supplement your existing card setup as it has some very useful points multipliers. Unlike the American Express Platinum, it's a viable card to use whilst traveling as it gets you points on everything you can think of in terms of traveling and transit whilst you're traveling. It also has a realistic credit that you can use to completely offset the annual fee.

It is a great travel credit card and one of my favorite travel credit cards on the market. Unlike some other branded travel cards, this gets you earnings in every travel category you can think of and has travel related credits, which other cards don't always have. If you travel even only once or twice per year, this card could be great for you.
