Flight booked for July

My brother is graduating during the last week in July. After a lot of to-ing and fro-ing, I've finally booked my flight home! It been a bit difficult what with my schools changing in August and the BoE's need for SHS ALTs to run seminars during teh summer, but it's finally sorted.

I'm a bit annoyed about the cost. The basic flight with Thai Airlines costs 130,000 yen (£650), which I thought was reasonable considering I was flying peak season. What I didn't expect was an extra 35,000 yen(£175) in taxes and 'fuel surcharges'. The Fuel Surcharge is actually twice as much as it was is February. A note was attached to my reservation email explaining the reasons behind the higher surcharge. Care to guess? Yep, it's the old "rising price of oil" excuse, which to me is 'business speak' for "we'd like more money off you, so we're inventing a surcharge so we can blame someone else and look like a caring company forced to do something bad instead of the money grabbing b@stards we really are".

I wonder if it is possible to consume 175 quid's worth of beer and snacks in a twelve hour flight?
