I rarely do ticket bookings myself these days, but I will have to book a ticket online myself for a flight in the summer. I was wondering - I know in the old days, the earlier you book, the cheaper your ticket would be. But with all the price discrimination and other calculations that goes on behind the screens, can anyone confirm that booking ASAP is still economically the best way to do it, or is it actually cheaper to wait a little?

Thanks,
