I recently flew between two NYC airports and LAX and did not encounter free wifi or plentiful outlets. They have outsourced wifi to Gogo (paid).
Some airlines will take over an entire terminal at an airport (e.g., JetBlue, Virgin America) and make it much better on both fronts. But in my experience that is not the norm.
