Something we never talked about in my primary flight training is landing fees.
How does one find out which airports have landing fees, and how much they are?
Are landing fees common?
How are these fees billed?
The legend in the front of the AFD says that landing fees will be mentioned in the "airport remarks" section, but I haven't found mention of it (looking at the AFD entry for SFO as an example: http://aeronav.faa.gov/pdfs/sw_151_5MAY2011.pdf ).
