RE: spotting at Rome(FCO), Nice, Naples
Sorry , but HAJ is the three letter-code for the the Airport of Hannover/Germany.
So I am a spotter from Hannover (HAJspotter)
Hannover is ca. 170km south of Hamburg and have an airport with about 5 Million pax.Hapag-Lloyd has its headquarter here.
Most interesting in HAJ is the CIS charters with some exotic airlines like Sibir Airlines,Air Kazakstan,Omskavia,Saravia,Chelyabinsk Air Enterprice and lots of more.
