It seems domestic* flights are cheapest 21 days in advance, and international flights cheapest 34 days in advance.
I must confess that I've been booking further and further in advance recently, as I enjoy planning and booking travel nearly as much as I enjoy travelling. Over the last year I've been booking 6 to 8 months in advance. Clearly this has to stop...
*It's not clear whether they mean all domestic flights, or just the USA.

The study only evaluated prices starting 6 months in advance, so it isn't applicable to what you paid 6-8 months in advance. I've booked several flights 6-11 months in advance over the lest 2 years and only found one that decreased, and only about 5%, in the intervening period.
The savings by booking 21 days in advance is <10%, so is it worth possibly saving that for the uncertainly of knowing?
