Oldest airliner in service
Anyone willing to take a stab at which is the oldest commercial airliner in service today with a major Western or international airline ?
I know definitions here can vary. I am not thinking of a clapped out 40 year old 727-100 in the boondocks of South America, but - like I say - major international scheduled or non-scheduled carrier. I also know cycles and hours make a difference as well. But for simplicity the oldest in calendar years ?
Was thinking, to kick-off, of some of Northwest's old DC-9-30s.
