Best time to book a flight?

My husband and I just got married and are looking at taking a delayed honeymoon to Maui in July. When is the best time to book a flight for this? Looking right now it looks like it would be approximately $5K for both of us as we are looking to fly business class since it’s a longer flight and my husband is a bigger guy and likes the space. Are their typically good Black Friday deals for flying? Or is it better to wait around 2-3 months in advance.

The closest airport to us is Rochester, NY which is tiny so we’re looking at flying out of Toronto or even JFK (and open to other suggestions)

Any advice/suggestions would be helpful!
