I did Rekyavik to Frankfurt in a 350 which was nice, got up to 174kts groundspeed inbound to Aberdeen. Via the Faroe Islands.
Skopje in a 350 (Macedonia just as they were bombing Kosovo! Very helpful RAF air defence co-ordination chap let me through the net) to Münster in Germany straight through Transylvania without being bitten!
Münster to Alexandria in a 206B 1999NM according to my GPS via Italy, Greece and Cyprus. Don't trust the wind forecasts!
Spain, Portugal and the South of France nearly every year with 205's
Lost my side window ( Bell 205) due to vibration cracks over the Alps in 11500ft wearing just a t-shirt on the way to San Remo. Got a new one made up and I wore a jacket on the way back and the damn thing blew out again! They were long and cold flights.
