Earn a 20% Bonus When Converting Marriott Rewards Points to AA Miles
From now until October 31, 2015, you can convert your Marriott Rewards points into American Airlines AAdvantage miles and earn a 20% bonus. Is this limited-time offer worth acting on? Let's take a look.
To get 50,000 AA miles (worth $850, according to TPG's valuations), you'll need to transfer 140,000 Marriott Rewards, worth $980. So you're ultimately losing $130 in value during the transaction based on the regular transfer rate.
Once you throw in the 20% bonus, though, you're essentially buying 60,000 AA miles worth $1,020 for $980, so you're coming out ahead by $40. It's not exactly the steal of the century, but if you need AA miles for a particular redemption and have a ton of Marriott Rewards points going unused, this offer could make sense.
You can also use the transfer bonus for hotel and air packages, in which you receive miles when you redeem Marriott points for a seven-night stay. In general, this only makes sense with higher category hotels, and then only if you're able to stay a full seven (consecutive) nights. Still, if you were planning to take advantage of one of these awards, now's the time to do it!
