Not passenger airliners though. The most common passenger aircraft in active service shares the fuselage dimensions with the Boeing 707 which first saw service in the 1950s, but there aren't any 707s left in regular civil service.

Commercial aircraft rarely continue in passenger service beyond 25 years, never mind 65, and the maintenance requirements as well as the fuel bill means it doesn't make financial sense to try.
