I've seen them set at pretty consistent levels for many years, generally between £2800 and £3300. The past 12 months has seen them at £41000-£4300 no matter what time of the year I've been flying - in fact Thai were cheaper on a few occasions which is something totally unheard of. Now they've dropped back down to the £3200 mark. I get they can change their prices and I get that peak season may attract premium pricing but they seem consistent for the rest of this year at the lower price. I just don't get it. Anyhow...time to move on.
