It was delivered to Austrian Airlines on 20/12/71. Nowadays it is registered to Air Tran. Don't know if it is still operational though.
I've probably flown older planes, including a BMA Viscount, but I didn't record their registration.
The newest plane I've flown on is an Air 2000 757 registration G-OOBC. It's first flight was on 17th February 2003.
