Sometimes there are sales in Aug but generally the earlier the better.

I feel like there is a sweet spot around September. I don't think you'll see the best price if you look now; but if you keep an eye on fares, you'll get a good sense of the market price and you'll see a dip if it comes.

Sadly, the earlier the better. We travel to India regularly over Christmas and you don't want to wait too long...fares can be almost double in December!

I'm hoping the rule of thumb of the earlier the better isn't accurate.
