British Airways is notorious for its "fuel surcharge", which is not a government-imposed tax. It's just an extra fee they tack on to make sure the low advertised ticket price ends up costing you enough for them to make a profit. The worst is when you use frequent-flier miles to book with them; you still have to pay the "fuel" surcharge, which guarantees they get an amount, in cash, equal to an economy-class fare even for your "free" ticket.
