Don't airlines negotiate fuel costs like a year in advance just to make sure they can pay a normalized amount throughout the year? If they negotiate these for the future, there shouldn't be any suprises (i.e. fuel surcharge). If they aren't negotiating for fuel prices, then why have the surcharge in the first place if it's just the actual fuel cost? It's all a game to keep the initial ticket price down and then they slap on a whole bucket of fees by the time you are done entering in your CC info. Google Flights is usually pretty good at telling you what the cost will be before you even click through to the airline's website.
