When I am not flying I like to go to my home airport. Stansted. I spot with the log book because it tells you airline codes, frequencies, airport codes and lots more. It gives you lot of pages to write what aircraft, airline, registration, flight number and lots more. One thing which is not so good is that the lines are quite small so not much space to write on a line. I think this is worth the money and would recommend it to spotters.
