Next time wait for a fare war instead of booking at their everyday low price.
Airlines used to offer price protection against themselves when they felt it was advantageous to secure bookings and plan capacity in advance. Apparently that strategy is no longer advantageous to the airlines.
If fewer people booked that early maybe the airlines might reconsider.
