I have moved these posts from another thread as it's an important issue.
They would have caught me. I had assumed that prices were cheapest the further away you book.
So when should one book?

I book multiple flights. About 6 months in advance. Particulary if it's any flights that are around school holidays. I have a pretty good idea of when it will be cheapest. For example after Halloween to about 2 weeks prior to Xmas is the cheapest and quietest time to travel.
Both Aer Lingus and Ryanair have sales. But this just knocks a few Euro off and when I compare the sales with what I've already booked I've never overpaid. The reason for this is the cheapest seats sell off first, so by the time the sale comes you might be at the next price level up.
Most Ryanair flights we use are nearly fully booked. We always book a seat now too. And I recently cancelled 4 flights for the new baggage rules and booked 4 alternative flights with the bags in the hold included and the difference in the 4 cancelled and the 4 new bookings was 1 Euro. But now we have priorty boarding, plus a bag on board.
The most expensive time is Halloween, mid term, Easter and not xmas so much as you have so many options on that, in general. It's worst when xmas is very close to the Friday. We no longer fly to Ireland for xmas. As it is just not worth it. Instead we find if you travel anywhere just after the 25th and back on or before the 31st it's also quite cheap .
July and August is also expensive because of family holidays.
Ryanair have a neat tool on their website where you can actually pick which day in any given month is the cheapest.
And if you're willing to travel in the middle of the night, ie 6 am, those tend to be the cheapest option.
