I can still get great fares to many locations, it's the "++" that's getting old. Surcharges, fees, etc. I still trip over $29ow fare-only, that turn into $300ai.

Supply-and-demand. If there's no demand, it's either sell it at what the market will pay for it, or not sell it at all. There's many flights I've flown that were half-empty, and the lowest fare day-of-departure was Y. Huh?
