I agree. I monitored the flight prices for 3 months before booking. You're not guaranteed to get the best price but as Mark says, as long as you're happy with the price.

One tip though. Once you've booked, don't go back on to look, you might just get upset?! (i saw a £700 reduction in the price i paid within 6 weeks of booking).

FYI i Booked 8 months in advance.
