American Express added Etihad Guest miles as its 17th airlines transfer today.

You can send Membership Rewards in increments of 1,000 points to Etihad miles at a 1:1 rate.

Etihad Guest is already a 1:1 transfer partner of Citi ThankYou Points. In November 2015, we saw a 25% transfer bonus from many programs including Citi ThankYou Points to Etihad Guest miles. I expect if we see a future transfer bonus like that, American Express Membership Rewards would be included.
Uses of Etihad Miles
Etihad Guest miles are NOT good for booking Etihad flights.

The Starwood Preferred Guest personal and business credit cards from American Express now come with 35,000 bonus Starpoints for spending $3,000 and $5,000 respectively in the first three months of cardmembership.

Enroll any Membership Rewards earning card today for 2x Membership Rewards at Amazon on purchases through July 31, 2016.

Sign into your American Express account, click on the card you want to enroll, and scroll down to see your "Amex Offers & Benefits."

For my AMEX Platinum, the Amazon offer was listed second.

You can enroll through July 31, 2016 and earn one bonus point per dollar on Amazon purchases made after enrollment through July 31, 2016. Bonus points will post by October 29, 2016.

Bonus points are not available at foreign versions of Amazon.

You can only get the bonus on American Express credit and charge cards once per lifetime.

In 2014, American Express changed its churning rules so that you could only get the bonus on a personal credit card once per lifetime.

Now the rule has been extended to business cards.

This follows the general trend of tightening the giving of bonuses by banks. For instance, Chase is about to institute a rule that you'll be denied for a credit card automatically if you've opened five other credit cards in the last 24 months.

I expect to see further tightening, and I expect the changes to be profitable for the banks.

The Citi Prestige® Card comes with 40,000 bonus ThankYou Points after $4,000 in purchases made with your card in the first 3 months the account is open.

I will spend over 200 nights this year in Airbnb apartments--here's where I am sleeping in 2015--so three pieces of news about Airbnb caught my eye today.

Most (all?) AMEX cards are offering $50 off a $100 Airbnb purchase made by 12/31/15.
You can use AMEX Membership Rewards to pay for Airbnb stays.
You can earn Virgin America Elevate points for Airbnb stays.

Right now, if you sign up for Airbnb through my referral link, you’ll get $25 off your first stay, and I’ll get $25 off my next stay.

American Express is offering real FICO scores for free to cardholders. Get yours here. Barclaycard, Citi, and Discover already offer real FICO scores for free to cardholders, so by now everyone who opens rewards credit cards should have free access to their real FICO score.

Your FICO score is the main or one of the main factors in all decisions lenders make about whether to extend you credit, how much, and on what terms. Watch it. Guard it. Keep it high.

American Express christened the Saturday after Thanksgiving, and the day after Black Friday, as Small Business Saturday in 2010. Every year since then, American Express has offered $10 to $30 in statement credits per American Express card for shopping at small businesses on Small Business Saturday. There are probably people who have racked up over $1,000 in free statement credits from American Express in the last five years.

Well this gravy train is over, at least for this year, but I'd guess forever.

The page that shows American Membership Rewards transfer partners seems to require sign in, so I will put the partners and ratios here for those who are considering getting an American Express card and want to see where their points can transfer.
