I got a fax reply from Venice Tessera LIPZ:
"we are sorry but cannot accept this schedulation (sic) flight due parking problems and general aviation trafic congestion"
I wonder if an airport is allowed to refuse IFR traffic in this way?
The Jeppview 3 text pages data shows 2 HRS PPR. Curiously it also shows no Avgas - just like it used to in 2004 and 2005.
So I have tried to contact San Nicolo, so far no reply.
Trieste is another option; down the road from Venice. Last time I went there they were very nice.
