Mysql get things after certain date

So, I have a database table holding tickets. One of the fields is "availableUntil".

when I make the database call to get tickets, I want to be able to exclude those tickets who's date has already been passed relative to the current dat开发者_StackOverflow社区e.

Anyone know of a way to do this?

SELECT blablabla... WHERE availableUntil >= CURRENT_TIMESTAMP

SELECT [what_you_want] FROM your_base WHERE availableUntil > CURRENT_DATE();
