Taxiied by the gate yesteday. Slight slope for about one plane length, at which point, at least from my perspective, the slope increased.
In general the ramps seem to slope up to the terminal. The worst, fortunately not that common, are the 'downhill' gates. Nothing like trying to pushback when the ramp's damp and the tug can't move the aircraft because of the slope(LAX comes to mind). Yes, the new, lighter, cheaper tugs. Field tested, just not on damp, 'uphill' gates.
