I also booked before I registered and recieved the 2500 miles. I have another trip next week that I booked after registering so hoping for another 2500.
To those of you saying it is "targeted". Doesn't it have to be targeted? It is your birthday.
It's not only targeted to your birthday though. You have to have a birthday during the promotion AND be targeted. For example my husband with a January birthday got a big old ROCK when trying to register for the January Birthday Promotion.
