The NBA American Express card is sending out emails to its cardholders regarding a bonus for spending money towards travel.
If you spend $1,000 or more towards travel between July 1st and July 15th, you will earn a 5,000 point bonus which is worth a $50 statement credit.
Bonus seems to include Airlines, Hotels and Car rentals. This should be on top of the regular 1,000 points you will earn for spending $1,000 so it would be the equivalent of 6% towards travel.
Email does not mention anything about being a targeted email but it might be worth calling up if you don't get the email to see if you are included.
