Evening Alan,
Regarding code 34C290, I have checked 'MyLog' and it was at FL360 squitting for 20 minutes. It was also using Flight ID ORO901. ORO relates to Clipper National Air therefore it looks like it was one of their aircraft miscoding or perhaps a new aircraft on delivery. Their website shows them owning 3 aircraft, EC-LZS, EC-LDK and EC-LQF. EC-LZS uses 34458D, EC-LDK uses 34340A and EC-LQF uses 344290. The latter looks a distinct possibility particularly as it used to miscode 344280 !
