I can't do a proper cut and paste due to lack of skills on the iPad but here is what I got for Sunday 24 December to Saturday 6 January. (The first and last days of holiday - Saturday to Sunday - were booked up).

Delta flights are absurd at 7,724 Air Miles. But American Airlines has six options at 2,600 Air Miles and $139.91 taxes.

It may be better availability with two one ways. If you give me your ideal dates I can look it up for you.
