I think the Douglas DC-3 may take exception to that.
Of course that would depend on the criteria by which you judge.
But as for longevity is concerned I doubt that the 747 has a chance.
Initial service of the DC-3 was 1936 and it is still flying today
The best airliner ever made.

I worked for Trans-Texas Airways from ‘63-’65 (which progressed into today’s Southwest Airlines). Most of the aircraft were DC-3s, as TTA was only flying to a couple of spots in NM and several in LA, beyond TX. Many of the aircraft had placards with dates of 1935-37, but they were workhorses that flew through thunderstorms and delivered passengers safely. The C-47 military version was also a workhorse. ...DC-3s are still flying today, 80 years from birth.
OK. Jetliner would be more accurate.
