The description of the $300 travel credit seems to say that you get it annually and that "annual" is from when you open the account until the end of the year and then each calendar year thereafter.
If so, then doesn't that mean that if you open an account now, that you could get the $300 benefit now and then again in 2017, even before your next annual fee is due?
A statement credit will automatically be applied to your account when your card is used for purchases in the travel category, up to $300 in statement credits annually ("annually" means the year beginning with your account open date through the first December statement date of that same year, and each 12 billing cycles starting after your December statement date through the following December statement date).
