If you like commercial service airports, prefer print material and don't have any access to trade magazines, I would like to recommend 'Airports of the World' magazine. It is published by Key Publishing based in the UK. The magazine is published every 2 months. It has quite a good geographical spread of airports featured with well taken pictures and good write ups.

Key Publishing also publishes a monthly magazine 'Airliner World'. (Click here)
