Too early to book flight for winter break?

<p>In about 2 wks my D will be off to OCU and is very excited. Of course, all I can think about is how long til she comes home again. Since airline tix just keep going up I was hoping to buy a ticket sometime soon for the winter break but I don’t know when it’s “safe” to book a flight. I’m wondering if this is even possible to do until they’re actually on campus and can find out when their last final exam is. I’m hoping those of you who are veterans at this can give me some guidance. (I did already buy a ticket for Thanksgiving but that didn’t seem so complicated).</p>
